Cimex lectularius, the common bedbug is an important, emerging pest of both veterinary and medical importance. Here a recently discovered, genetically distinct new species of the C. lectularius group is described morphologically, as Cimex pulveratus Hornok sp. nov.
A new species Nenteria lii sp. n. is described on the basis of adults and deutonymphs collected in bamboo (Phyllostachys sp.) leaf litters in Xinxiang (Henan Province, China). The new species is very similar to the species Nenteria japonensis Hiramatsu, 1979, but the apical process of the female genital shield rounded and smooth in the new taxon, but serrate in the previously described Japanese species. A new key to the Eastern-Palearctic Nenteria species is given. A list of the collected bamboo leaf litter associated mites is presented.

The hypopi of the species Sancassania chelone Oudemans, 1916 were collected from four pest beetle species, namely Melolontha melolontha (Linnaeus, 1758); Melolontha hippocastani Fabricius, 1801; Holochelus aequinoctialis (Herbst, 1790) and Tropinota hirta Poda, 1761. The infestation rate was the highest in H. aequinoctialis (80%), while it was 50%, 28% and 13% in M. hippocastani, M. melolontha and T. hirta, respectively. The majority of the mites were found on wings in case of the two Melolontha species, in contrary, the mites were present on the abdomen of the H. aequinoctialis and T. hirta. Melolontha hippocastani Fabricius, 1801; Holochelus aequinoctialis (Herbst, 1790) and Tropinota hirta (Poda, 1761) are new host species of S. chelone.
The pine pest, Cenopalpus lineola (Canestrini and Fanzago, 1876) was discovered after 45 years again in Hungary. Proto-, deutonymphs, male and female specimens were collected, therefore a new and detailed re-description are presented with description of the leg chaetotaxy of the immature stages.

Babesia vesperuginis is the only piroplasm known to infect bats. Unlike most members of the genus Babesia, it is probably transmitted by a soft tick species (i.e. Argas vespertilionis). Recently, two studies have been conducted to clarify the phylogenetic status of this species, and both agreed on placing it into a basal position among Babesia sensu stricto (s.s.). However, several important groups of piroplasms were not included in the already reported phylogenetic trees of B. vesperuginis isolates. Therefore, the aim of the present study was to amplify an approx. 950-bp fragment of the cytochrome c oxidase subunit 1 (cox1) gene of B. vesperuginis from A. vespertilionis specimens, and to compare its sequences with those from other piroplasmid groups in a broader phylogenetic context. Sequence comparisons focusing on either 18S rRNA or cox1 genes, as well as phylogenetic analyses involving separate and concatenated 18S rRNA and cox1 sequences indicate that B. vesperuginis is more closely related to the phylogenetic group of Theileriidae than to Babesia s.s. In particular, B. vesperuginis clustered closest to Cytauxzoon felis and the ‘prototheilerid’ B. conradae. The results of this study highlight that B. vesperuginis is a unique and taxonomically important species, which should be included in future studies aimed at resolving the comprehensive phylogeny of Piroplasmida.

Kinetoplastids are flagellated protozoa, including principally free-living bodonids and exclusively parasitic trypanosomatids. In the most species-rich genus, Trypanosoma, more than thirty species were found to infect bats worldwide. Bat trypanosomes are also known to have played a significant role in the evolution of T. cruzi, a species with high veterinary medical significance. Although preliminary data attested the occurrence of bat trypanosomes in Hungary, these were never sought for with molecular methods. Therefore, amplification of an approx. 900-bp fragment of the 18S rRNA gene of kinetoplastids was attempted from 307 ixodid and 299 argasid ticks collected from bats, and from 207 cimicid bugs collected from or near bats in Hungary and Romania. Three samples, one per each bat ectoparasite group, were PCR positive. Sequencing revealed the presence of DNA from free-living bodonids (Bodo saltans and neobodonids), but no trypanosomes were detected. The most likely source of bodonid DNA detected here in engorged bat ectoparasites is the blood of their bat hosts. However, how bodonids were acquired by bats, can only be speculated. Bats are known to drink from freshwater bodies, i.e. the natural habitats of B. saltans and related species, allowing bats to ingest bodonids. Consequently, these results suggest that at least the DNA of bodonids might pass through the alimentary mucosa of bats into their circulation. The above findings highlight the importance of studying bats and other mammals for the occurrence of bodonids in their blood and excreta, with potential relevance to the evolution of free-living kinetoplastids towards parasitism.
