Members of the major species-group can be distinguished from other Sagola speciesgroups by the following combination of characters: body small, length 1.5–2.8 mm ; male head triangular, widest across temples ( Fig. 66n ), female head bluntly triangular, widest across eyes; temple of male head depressed and projecting ventrally ( Fig. 66n ); male neck with ventral patch of dense setae anteriorly ( Fig. 66o–t ); male hind wings fully developed; abdominal tergites IV–VI with discal carinae; genitalia robust and convex ( Fig. 66g –l ). KEY TO SPECIES OF THE MAJOR SPECIES- GROUP The key is based on male specimens because most female specimens are indistinguishable based on external morphology. 1.
