In this study the Ptyngidricerus Van der Weele, 1908 genus has been revised and in the course of this 2 new genera and 4 new species are described. The description of the new genus was made possible apart from the male samples, the females (P. albardanus) which were recorded and supplement of the description based on damaged specimens (P. ira­nensis) earlier enabling the evaluation of their taxonomic status. The following species belonging to Ptyngidricerus genus: Ptyngidricerus albardanus albardanus (McLachlan, 1891), Ptyngidricerus albardanus pterostigmatus Alexandrov Martynov, 1926, Ptyngidricerus pseudo­albar­da­nus sp. n. Ptyngidricerus persepolisensis sp. n. and Ptyngidricerus sen­da­nensis sp. n. from Iran and Ptyngidricerus pakistanensis sp. n. from Pa­kistan. Apart from describing the new species the authors present a des­cription of the female Ptyngidricerus albardanus albardanus (McLachlan, 1891) which has so far not been known according to the literature on this species. The earlier described species were combinated on the basis of their genitalia and external morphological characteristics in new genus: Iranoidricerus iranensis (Kimmins, 1938) and Omanoidri­cerus venustus (Tjeder and Waterston, 1977). The illustration of the female and male genitalia of Iranoidricerus iranensis Kimmins, 1938 is also presented. On account of sexual dimorphism a key is given for identification of the female and male specimens with 25 figures.

In recent years, Aleuroclava psidii (Singh) (Hemiptera: Aleyrodidae) has been extending its geographic range due to the international movement of plant material. In October 2013, it was discovered on Psidium sp. (Myrtaceae) in Egypt and represents the first record of this species in Egypt and the Western Palearctic region.

Species of the family Signiphoridae (Chalcidoidea) are primarily hyperparasitoids associated with scale insects, whiteflies and mealybugs through other Chalcidoidea; however, certain species are primary parasitoids of these hosts. Recent collections and a review of the literature indicate that the following five species of the family Signiphoridae are known to occur in Egypt: Chartocerus niger (Ashmead), Chartocerus subaeneus (Főrster), Signiphora fax Girault, Thysanus sp. and Signiphora flavella Girault, the latter newly recorded in Egypt and Palearctic region. A key to the Egyptian signiphorid species is included.
