Nine species of Mymaridae and Trichogrammatidae parasitic on eggs of Proconiini sharpshooters (Cicadellidae: Cicadellinae) were collected in northwestern Mexico in relation to neoclassical biological control efforts against glassy-winged sharpshooter, Homalodisca vitripennis (Germar), in California. Gonatocerus chula Triapitsyn and Bernal sp. n., which belongs to the ater species group of Gonat...

The smallest flying insects commonly possess wings with long bristles. Little quantitative information is available on the morphology of these bristles, and their functional importance remains a mystery. In this study, we (1) collected morphological data on the bristles of 23 species of Mymaridae by analyzing high-resolution photographs and (2) used the immersed boundary method to determine via...

A rare fairyfly (Hymenoptera, Mymaridae) genus, Ganomymar De Santis, 1972, is revised and rediagnosed based on both sexes; its males were previously unknown. This which has remarkable structures the propodeum peculiar fore wings in females, known only from Madagascar Afrotropical region. Its type species, dessarti redescribed illustrated a non-type female specimen. Three new species of are desc...

Morphological identification and molecular study on the COI gene were simultaneously conducted on Anagrus Haliday 'atomus' group individuals collected in the field in Italy or supplied from a UK biofactory. Females were morphologically identified as A. atomus L. and A. parvus Soyka sensu Viggiani (=A. ustulatus sensu Chiappini). Alignment of COI gene sequences from this study permitted recognit...
