Gerbekas Argaman, 2003
Remarks.
This genus is characterized by the antenna with flagellomeres wide with pubescence dense and short, the forewing with nebulous Cu vein, the hypopygium with wide spiculum and branches lobate, and the male genitalia with parameres S-shaped (Azevedo et al. 2018). However, it was found to be polyphyletic (Figs 4 - 6). In order to solve this problem, Heterocoelia fischeri Móczár, 1971 is herein removed from the synonymy of Pycnomesitius peringueyi (Kieffer, 1913) and transferred to Gerbekas, G. fischeri ( Móczár, 1971) stat. rev. et comb. nov.; and Heterocoelia nikolskajae Móczár, 1984 is herein removed from the synonymy of Heterocoelia obscura ( Móczár, 1984) and also transferred to Gerbekas, G. nikolskajae ( Móczár, 1984) stat. rev. et comb. nov.
