Abstract

A new subgenus of leaf-beetles Chrysolina (Ambrostomima subgen. nov.) is described from Hengduan Mountains (Sichuan and Gansu, China). It is characterized by the following main characters: body metallic, mostly green mixed with purple or one-colored green; last maxillary palpomere elongate, narrow, similar in both sexes; elytral punctures arranged in more or less distinct rows or mostly irregular; elytral epipleura inclined outside; hind wings completely missing; pygidium without furrow in apical 1/2 in most species; tarsomeres 1–3 more or less broadened in male, narrow in female, with entire sole in both sexes.

The subgenus consists of 25 species: Chrysolina amica Lopatin, Ch. baimana Lopatin, Ch. davidiani Lopatin, Ch. korotjaevi Lopatin, Ch. luyoui Daccordi et Ge, Ch. matruelis Lopatin, Ch. mirabilis (Daccordi), Ch. nesterovae Lopatin, Ch. pingchuana Lopatin, Ch. purpureoviridis Lopatin, Ch. rotundata Lopatin, Ch. sichuanica Lopatin, Ch. sicieni Ge et Yang, Ch. songpana Lopatin, Ch. viridiopaca Lopatin, Ch. aurita sp. nov., Ch. auriviridis sp. nov., Ch. bellissima sp. nov., Ch. ferdinandoi sp. nov., Ch. korolevi sp. nov., Ch. latipes sp. nov., Ch. ovata sp. nov., Ch. pilula sp. nov., Ch. pulchra sp. nov., and Ch. tortilla sp. nov.

Types of all previously described species except Ch. luyoui are examined. Males of Ch. mirabilis and Ch. viridiopaca are examined and described for the first time. Key to species is compiled. Type localities of Ch. viridiopaca and Ch. songpana are corrected. Photographs of habitus and male aedeagi are presented for all species.

Introduction

The leaf beetle fauna of the mountainous regions of China is very rich in species, many of which are still undescribed. The author recently described a new subgenus Chrysolina (Volosatik Bieńkowski, 2022) to include three previously known species and four new ones from NW part of Yunnan Province (Bieńkowski 2022). The present article is devoted to the designation of a new subgenus оf the genus Chrysolina Motschulsky, 1860 which includes 15 previously known species and 10 new ones from Hengduan Mountains (Sichuan and Gansu Provinces).

The Hengduan Mountain region is a biodiversity «hotspot» with high species number in different groups of beetles, such as Cantharidae, Curculionidae, Carabidae, some genera of leaf beetles (e.g. Suinzona Chen, 1931) (Belousov & Kabak 2003, Ge et al. 2011, Davidian 2020, Grebennikov 2022, Liu et al. 2022). Ge et al. (2011) noted that the species richness and endemism of this area has generally been attributed to the role of the region as a refugium during Quaternary climatic fluctuations and the high environmental and habitat heterogeneity. Chen and Wang (1984) described Chrysolina (Timarchomela) dalia Chen et Wang, 1984, Ch. (T.) nushana Chen et Wang, 1984, and Ch. zhongdiana (incertae sedis) Chen et Wang, 1984 from Hengduan Mountains.

The first species of the subgenus in question, Ch. mirabilis Daccordi, 1976 was described (Daccordi 1976) as a member of the genus Semenowia Weise, 1889. Subsequently Bieńkowski (2013) found that Ch. mirabilis does not belong to the genus Semenowia (subgenus of the genus Chrysolina after Daccordi 1994), but forms a natural unnamed species group together with Ch. davidiani Lopatin, 2002, Ch. luyoui Daccordi et Ge, 2011 and Ch. sicieni Ge et Yang, 2011 within the genus Chrysolina.

Lopatin (2002, 2004, 2005, 2007, 2009, 2011, 2013) described Ch. amica Lopatin, 2009, Ch. baimana Lopatin, 2009, Ch. davidiani Lopatin, 2002, Ch. korotjaevi Lopatin, 2009, Ch. matruelis Lopatin, 2011, Ch. nesterovae Lopatin, 2011, Ch. pingchuana Lopatin, 2013, Ch. purpureoviridis Lopatin, 2005, Ch. rotundata Lopatin, 2002, Ch. sichuanica Lopatin, 2002, Ch. songpana Lopatin, 2007, Ch. viridiopaca Lopatin, 2004, and also established that Ch. davidiani, Ch. nesterovae, Ch. matruelis, and Сh. pingchuana form a natural unnamed group, and compiled a key to species (Lopatin 2011, 2013).

Daccordi et al. (2011) described Ch. luyoui and Ch. sicieni and noted their relationship to each other.

Bieńkowski (2019) established unnamed species group that included Ch. davidiani, Ch. korotjaevi, Ch. matruelis, Ch. mirabilis, Ch. nesterovae, Ch. sichuanica, Ch. sicieni, Ch. songpana, as well as another unnamed species group that included Ch. amica, Ch. luyoui, Ch. purpureoviridis, Ch. rotundata, Ch. viridiopaca, and compiled keys to the species of these two groups; species Ch. pingchuana and Ch. baimana were considered separately from others.

However, there have been no taxonomical revisions devoted to the endemic fauna of the genus Chrysolina in this area.

In the present article, based on the study of comparative morphology, it is established that the 15 species under consideration as well as 10 new species form a natural group that has been assigned the status of the new subgenus Ambrostomima.

Materials and methods

Materials, including the type ones, from the following museums (names of curators in brackets) and private collections have been studied:

  • BC – the author's collection, Zelenograd, Russia;

  • DC – M. Daccordi's collection, Verona, Italy;

  • NMB – Naturhistorisches Museum Basel, Switzerland (M. Borer);

  • RC – P.V. Romantsov's collection, St.-Petersburg, Russia;

  • ZIN – Zoological Institute, St.-Petersburg, Russia (A.G. Moseyko).

All holotypes and some paratypes of the new species are deposited in Zoological Institute, St.-Petersburg, Russia (ZIN). The other paratypes are deposited in the author's collection (BC), P.V. Romantsov's collection (RC), M. Daccordi's collection (DC), and Naturhistorisches Museum Basel (NMB). During the revision of the subgenus, the type specimens of all known species, except for Ch. luyoui, were studied. The latter species was described on the basis of the single specimen deposited in Institute of Zoology, Chinese Academy of Sciences and is not available to the author. Morphological description and terminology of structural details follow Bieńkowski (2019). The original descriptions of previously described species were incomplete and did not contain a number of important diagnostic features. Therefore, all these species are redescribed. The species descriptions are ordered as follows: previously described species first, alphabetically, then new species, alphabetically. Photographs were made by a Nikon D-90 digital camera, combined with Tamron SP 70–300 mm F/4-5.6 and inverted Vega-12B 2.8-90 lenses, using Helicon Remote software. Images of the same objects at different focal planes were combined using Helicon Focus software.

Taxonomy

Family Chrysomelidae

Genus Chrysolina Motschulsky, 1860

Type species: Chrysomela staphylaea Linnaeus, 1758, by original designation

Chrysolina (Ambrostomima) subgen. nov.

https://zoobank.org/2F19B920-B0B4-485D-A63A-5EA9CB2B1141

Type species: Semenowia mirabilis Daccordi, 1976.

Diagnosis. Body entirely metallic, brightly colored, green with purple pattern (or vice versa), mostly with colored stripes on elytra, or entirely green, greenish-bronze, or with violet reflection, usually shining, rarely sericeous or dull.

Last maxillary palpomere elongate, narrow, as wide as penultimate one or slightly broader than the latter, barrel-shaped, or cylindrical, or slightly securiform, similar in both sexes.

Pronotum without anterior setiferous pores. Pronotal lateral impression different: furrow-shaped, broad, deep to shallow, or obsolete (absent), with large punctures or without them. Anterior side marginated, ciliate. Posterior side entirely marginated.

Prothoracic hypomeron without basal fold in most species, rarely with fold. Anterior coxal cavities broadly opened behind. Metasternum marginated anteriorly.

Humeral callus of elytron weak to obsolete or absent. Elytral punctures fine to moderate, mostly irregular or arranged in more or less distinct rows. Elytral surface mostly flat. Sutural furrow developed in all species, except Ch. matruelis.

Elytral epipleura inclined outside, visible along entire length in lateral view, apically with dense, or sparse setae, or without of them at all.

Hind wings absent.

Pygidium without furrow in apical 1/2 in most species, with distinct furrow along entire length in Ch. matruelis and shallow impression in Ch. korotjaevi.

Last abdominal ventrite simple, convex, with apical margin truncate or broadly emarginate in male, arc-shaped in female.

Tarsomeres 1–3 more or less broadened in male, narrow in female, with entire sole in both sexes. Claw tarsomere without denticles. Claws simple and separate from each other.

Differential diagnosis. The new subgenus belongs to the wingless mountain Chrysolina groups in the subtropics of China. It differs from the subgenera whose representatives inhabit Sichuan Province and the adjacent parts of Gansu and Yunnan Provinces in the following ways.

It differs from the subgenus Medvedevlevna Özdikmen, 2008 in the last maxillary palpomere longer than wide, longer than penultimate one or as long as the latter, elytral punctures finer, while Medvedevlevna has last maxillary palpomere broader than long or as long as broad, rather shorter than penultimate one, and elytral punctures much larger.

It differs from Ch. (altimontana (Rybakow, 1889)) species group of the subgenus Pezocrosita Jacobson, 1901a in elytral punctures not arranged in quite regular rows, and in the absence of long glabrous basal “heel” at 1st tarsomere, while Ch. (altimontana) group has elytral punctures arranged in 10 regular equidistant rows, and tarsomere 1 bearing long narrow glabrous basal “heel” ventrally.

It differs from Ch. (obovata (Jacobson, 1895)) species group of the subgenus Pezocrosita Jacobson, 1901 in the elytral punctures not arranged in quite regular rows, while Ch. (obovata) species group has elytron with 9–10 regular rows of punctures.

It differs from the subgenus Semenowia Weise, 1889 in dorsal coloration bright metallic, and in elytral punctures not arranged in quite regular and dense rows, while Semenowia has dorsum black with 7 equidistant regular rows of elytral punctures.

It differs from the subgenus Timarchomela Achard, 1922 in dorsum brightly colored, usually shining, pronotum usually with distinct lateral impression, elytral punctures always distinct, while Timarchomela has dorsum dark metallic or black, dull or sericeous, pronotum without distinct lateral impression, elytral punctures mostly obsolete (except Ch. costulata (Achard, 1922)).

It differs from Ch. (Allohypericia Bechyné, 1950) mauroi Lopatin, 2005 in the dorsum brightly colored, and elytral punctures not so regular, while Ch. mauroi has dorsum black with elytra bearing regular paired rows of punctures.

It differs from the subgenus Volosatik Bieńkowski, 2022 in the coloring characteristic of many species, included the combination of metallic green and purple spots and stripes, and elytral punctures never forming regular paired rows, while Volosatik has dorsum metallic, differently colored but never with metallic green and purple pattern, and elytral puncture rows paired, regular in most species except Ch. wangi Lopatin, 2005, consist of moderately large to large punctures. All members of Volosatik inhabit NW part of Yunnan far from the area of the new subgenus.

Due to the bright coloration, combining green and purple, the representatives of the new subgenus externally resemble the species of the genus Ambrostoma Motschulsky, 1860 and especially subgenus Parambrostoma Chen, 1936, but clearly differ in the structure of the metasternum characteristic of Chrysolina members (with entire bordering anteriorly), and absence of setiferous pores at pronotal anterior angles (Ge et al. 2012, Bieńkowski 2019).

Chrysolina ambigua (Chen, 1936) looks like the member of the subgenus Ambrostomima because of metallic green coloration with purple pattern, narrow last maxillary palpomere, pronotum anteriorly marginate, without impression and large punctures laterally, fine elytral punctures, epipleura inclined outside, with few setae at apex, metasternum entirely marginated anteriorly, absence of hind wings, tarsomeres 1–3 with entire sole. It differs in: pronotum with setiferous pores near anterior angles, elytron with distinct lateral transverse impression behind humeral callus, claw tarsomere bearing 2 narrow, spine-shaped apical denticles, pygidium with distinct longitudinal furrow (difference from almost all members of Ambrostomima subgen. nov. except Ch. matruelis). Chrysolina ambigua occurs in N India and Nepal. Ge et al. (2012) includes Ch. ambigua in the genus Parambrostoma.

Distribution: China: eastern slope of Hengduan Mountains (Sino-Tibetan mountains) in Sichuan Province and adjacent areas of Gansu Province at altitudes from 2,200 to 4,850 m above sea level.

Etymology. The new subgenus is named for its external resemblance to representatives of the genus Ambrostoma and in accordance with the traditions of naming subgenera or genera, such as Chrysolina (Pseudotimarchomima Daccordi, 1980) and Timarchomima Bechyné, 1950. Grammatical gender: feminine.

Body length: 6.8–7.5 mm (male), 7.4–8.0 mm (female); aedeagus 2.0 mm long, 0.6 mm wide.

Variability. Present description is based on the specimens from the type series. In addition, I examined 3 males and 3 females from other localities not far from the type locality. These specimens are distinguished from the types in the shape of pronotum (more rounded at lateral sides), with maximal width in front of the middle, more convex lateral calli, and lateral impressions deepened at the base. However, the shape of male aedeagus and proportions of the male fore-tarsomeres 1–3 are similar to those in Ch. amica.

Comments. In the original description (Lopatin, 2009), the word “holotype” is not mentioned in the section “Material”, but the description starts with “Holotype (male)…”, thus Lopatin (2009) showed awareness that a holotype needed to be fixed. The mention “Holotype (male)…” in the beginning of the description is enough and sufficient to accept the designation of the holotype. Type series of Ch. amica includes 5 males and 7 females collected in three localities. Type series of Ch. baimana includes 5 males and 9 females collected in three localities. These species are morphologically very close to each other. On the other hand, they have a large intraspecific variability. The main difference between the species is the structure of the male aedeagus. Females collected together with males can presumably be assigned to the same species. However, the paratypes, females of Ch. amica and Ch. baimana, collected in the same locality and on the same date (32°41′25″N / 104°14′42″E, 3,740 m, 26.06.2006), have no diagnostic differences. In addition, the holotype of Ch. korotjaevi was collected simultaneously with some of the type specimens of Ch. amica. Thus, the paratypes (females) of Ch. amica and Ch. baimana may actually belong to any of the three species named above.

Comments (see also “Comments” section under Ch. amica and Ch. korotjaevi). In the original description (Lopatin, 2009), the word “holotype” is not mentioned in the section “Material”, but the description starts with “Holotype (male)…”, thus Lopatin (2009) showed awareness that a holotype needed to be fixed. The mention “Holotype (male)…” in the beginning of the description is enough and sufficient to accept the designation of the holotype. This species was described from the same localities as Ch. amica. Chrysolina baimana has a great color variability. On the other hand, it differs from Ch. amica mainly in the characters of the male (fore-tarsi and aedeagus). Females (paratypes) of Ch. baimana and Ch. amica, collected simultaneously (32°41′25″N / 104°14′42″E, 3,740 m, 26.06.2006), have no diagnostic differences.

Comments (see also the “Comments” section under Ch. amica). The only known specimen of Ch. korotjaevi, male, holotype, was collected in the same locality and on the same date with some type specimens of Ch. amica and rather similar to them externally. A clear difference between the species is the shape of the aedeagus. In view of the unexplored variability of Ch. korotjaevi, and in the absence of the known females, such characters as body size, shape of the maxillary palpi, and proportions of male fore-tarsomeres 1–3 may overlap in Ch. korotjaevi and Ch. amica. It is possible that some paratypes, females of Ch. amica really belong to Ch. korotjaevi.

Pronotum 2.0–2.1 X as wide as long, broadest basally or at mid-length, with lateral sides rounded, more convergent forward than backward, with anterior side moderately emarginate, anterior angles protruding forward. Lateral callus convex along entire length, lateral impression narrow, deep in apical 1/3 and basal 1/3, and broad, shallow in medial 1/3. Lateral impression with several moderate (0.05 mm) punctures in medial 1/3 or without punctures. Pronotal disc and lateral calli evenly covered with dense, fine (0.02 mm) punctures. Several moderate (0.03 mm) punctures present along outer margin of lateral callus. Pronotum entirely marginate and ciliate anteriorly. Anterior and posterior setiferous pores of pronotum absent.

Prothoracic hypomeron convex, with irregular lateral wrinkles, without lateral impression. Anterior cavity of prothoracic hypomeron deep. Basal fold of prothoracic hypomeron broad, deep. Metasternum entirely marginate anteriorly.

Elytron with obsolete humeral callus. Elytral punctures fine (0.02–0.03 mm), rarely up to 0.05 mm, mostly irregular, with some hardly visible paired rows in anterior 1/2. Intervals finely sparsely wrinkled. Sutural furrow distinct at apical slope. Elytral epipleuron inclined outside, visible along entire length in lateral view, with sparse setae apically.

Pygidium with obsolete impression in basal 1/2 only.

Last abdominal ventrite simple, convex, with apical margin broadly truncate in male, rounded in female.

Male aedeagus 3.9 X as long as wide, almost parallel-sided, roundly truncate at apex, with apical denticles on ventral side. Setiferous pores present dorsally at sides of apical margin. Aedeagus evenly curved in lateral view, with flagellum tube-shaped, slightly exposed (Figs 7O; 12 F). Apical orifice 0.2 X as long as aedeagus length.

Female spermatheca present (Fig. 14F).

Body length: 5.3–6.0 mm (male), 6.0–7.0 mm (female); aedeagus 2.0 mm long, 0.5 mm wide.

Comments. Lopatin (2004) described this species on the basis of only one female with the label “Xinjiang, Boro-Khoro”. However, in Xinjiang, beetles with such morphological characters are not found till now. Besides that, Chrysolina viridiopaca belongs to a group of species that does not occur beyond Sichuan. The type locality label is evidently incorrect.

Lopatin (2004) correctly compared this species with Ch. rotundata from Sichuan, and distinguished it by: 1) body less shining, 2) different ratio of antennomeres, 3) wider pronotum, and 4) intervals of elytral puncture rows with few fine punctures.

A series of males and females from Sichuan being at my disposal, are similar to the holotype of Ch. viridiopaca in all features, including: 1) shape of frons, which is less convex and evenly punctate (more convex and devoid of punctures along middle in Ch. rotundata), 2) elytral punctures usually smaller than in Ch. rotundata. Shine of dorsal side is variable in both, Ch. viridiopaca and Ch. rotundata; 3rd antennomere 1.2 X as long as antennomere 5th in the both species (Lopatin 2004 erroneously noted that they are equal in length); shape of pronotum varies in Ch. viridiopaca and and does not differ this species from Ch. rotundata.

Discussion

Distribution of the species

All species of the new subgenus inhabit mountain habitats with altitudes from 2,200 (mainly from 3,000) to 4,850 m a.s.l., mostly the belt of alpine meadows (Figs 15, 1824). Fourteen out of 25 species have been found so far in a single locality for each of them (Figs 16 and 17). It may be due to the low dispersal capacity of these wingless beetles. A map of the total distribution of the species shows the existence of two isolated areas: northern one (Fig. 16) and southern one (Fig. 17). All species are distributed in only one of the areas. The subgenus includes five groups of morphologically related species (see the key to species): 1) Ch. amica, Ch. baimana, Ch. korotjaevi, 2) Ch. rotundata, Ch. viridiopaca, 3) Ch. bellissima sp. nov., Ch. luyoui, Ch. mirabilis, Ch. nesterovae, Ch. sicieni, 4) Ch. auriviridis sp. nov., Ch. ovata sp. nov., 5) Ch. pingchuana, Ch. tortilla sp. nov. The members of each group are distributed in only one of the areas, first three groups – in the northern area, two last groups – in the southern area. The remaining 11 species are morphologically distant both from each other and from the above mentioned groups.

Spermatheca and ovoviviparity

I had the opportunity to dissect the females of 17 of the 25 species. I found spermatheca in females of eight species (Ch. amica, Ch. baimana, Ch. ferdinandoi sp. nov., Ch. korolevi sp. nov., Ch. latipes sp. nov., Ch. ovata sp. nov., Ch. pingchuana, Ch. viridiopaca), including one ovoviviparous (Ch. korolevi sp. nov.). Besides that, I didn't find spermatheca in females of nine species (Ch. aurita sp. nov., Ch. bellissima sp. nov., Ch. davidiani, Ch. luyoui, Ch. mirabilis, Ch. nesterovae, Ch. purpureoviridis, Ch. sicieni, Ch. tortilla sp. nov.), including two ovoviviparous (Ch. luyiui and Ch. nesterovae). The presence of the spermatheca may be characteristic of representatives of the first and second groups of morphologically close species (see above) (females of Ch. korotjaevi and Ch. rotundata are unknown). The absence of spermatheca is typical for representatives of the third group. Since Holmgren (1904), there has been an assumption that the absence of the spermatheca correlates with ovoviviparity. Bontems (1988) found that there is no such correlation.

New and little used diagnostic features

Long setae at anterior and posterior angles of pronotum. The presence or absence of these setae is used as a diagnostic character in the systematics of different genera of Chrysomelinae, for example, Potaninia Weise, 1889 and Suinzona Chen, 1931 (Ge et al. 2011), Gonioctena Chevrolat, 1837 (Yang et al. 2015). The presence or absence of setae at posterior angles is rarely used in the systematics of the subtribe Chrysolinina (Ge et al. 2012). It can be more widely used in systematics and phylogeny of the subtribe, since it differs in different genera and species of the subtribe. So, the seta at posterior angle is present in all members of the genera: Ambrostoma, Parambrostoma, Crosita Motschulsky, 1860, Oreina Chevrolat, 1836, Camerounia Jolivet, 1949, as well as in Agrosteella indica (Hope, 1831), A. fallaciosa (Stål, 1862), Humba cyanicollis (Hope, 1831), Sphaerolina rajah (Guérin-Méneville, 1840), Sphaeratrix latifrons Gistel, 1857, S. tieutainei (Fairmaire, 1891) (Ge et al. 2012 and material examined). The seta is absent in all members of the genus Timarchomima Bechyné, 1950 and in different species of the genus Cyrtonus Latreille, 1829, as well as in different species of the genus Chrysolina (material examined). In the subgenus Chrysolina (Ambrostomima) subgen. nov., the seta at posterior angle of pronotum is present in Ch. pilula sp. nov., it is absent in all other species.

Ge et al. (2011, 2012), Yang et al. (2015) denote the setae at pronotal angles as trichobothria. In my opinion, this is incorrect. Unlike the simple seta, which is tapered, the trichobothrium has the same diameter throughout its length.

Anterior cavity of prothoracic hypomeron (presence / absence, shape). There was still no mention of this character in the works on systematics of the subtribe Chrysolinina. Anterior cavity is deep, for example, in Humba cyanicollis, shallow – in Agrosteella indica, A. fallaciosa, absent – in Sphaerolina balyi (Jacoby, 1893), S. rajah, Sphaeratrix latifrons, S. tieutainei and in all members of the genera Timarchomima and Camerounia (Bieńkowski 2019, material examined). It is equipped with a sharp tooth in the members of the subgenus Chrysolina (Chersomela Weise, 1914) and has a different shape in the species from different subgenera of Chrysolina (Bieńkowski 2019). In the new subgenus Chrysolina (Ambrostomima) subgen. nov., this cavity is developed, from shallow to deep, or absent in different species (see the descriptions and key to species).

The mentioned features deserve more attention and can be used to diagnose the species of the genus Chrysolina.
