Genus Ametrodiplosis Rübsaamen, 1910

Ametrodiplosis differs from other clinodiplosine genera by a greatly inflated costal base of male wing ( Figs 5, 7 & 9 ) in addition to the following combination of characters: flagellomeres I and II fused in both sexes; basal male flagellomeres usually binodal; each node with 1 set of short-looped circumfila, except some eastern Palearctic and Oriental species that bear 1 or 2 simple whorls of circumfila in addition to or instead of short-looped circumfila ( Grover 1970; Fedotova 2002, 2003; Fedotova & Sidorenko 2004); distal male flagellomeres gradually foreshortened and becoming evenly cylindrical, except the Oriental A. pareirae Grover , in which all flagellomeres are foreshortened and cylindrical ( Grover 1970); and third instar with bilobed spatula and integument ventrally with anteromedian field of raised and pointed cuticular warts on thoracic segments and abdominal segments I–VIII.
