First Findings of Gall Midges (Diptera, Cecidomyioidea, Cecidomyiidae) of the Tribes Karshomyiini (Mexican Amber) and Bremiini (Dominican Amber)

Abstract

Two new genera and species of gall midges are described from Lower-Middle Miocene amber, based on males, which have binodose flagellomeres possessing long looplike sensorial filae: Mexicanodiplosis katyae gen. et sp. nov. (Coquillettomyiidi, Karshomyiini) from Mexican amber, and Ipsseptemmyiarossi gen. et sp. nov. (Aphidoletidi, Bremiini) from Dominican amber. Coquillettomyiidi were previously unknown from fossil resins. An undescribed species of the genus Bremia was previously found in Mexican amber. This is the first gall midge to be described from Dominican amber. Altogether, including the new taxa, 11 species and eight genera of Cecidomyiinae with binodose flagellomeres were found in Mexican amber (five genera, five species), Dominican amber and Rovno amber (one genus, one species each), and Baltic amber (one genus, three species).
