27. major species-group (6 species) Diagnosis. 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.
