description: 28. insignis species-group
(24 species)
Diagnosis. Members of the insignis speciesgroup can be distinguished from other Sagola species-groups by the following combination of characters: body length 2.2–3.2 mm; antennomere 1 approximately 1.5 times longer than wide; male head triangular, widest across temples (Fig. 70y–z) and female head bluntly triangular, widest across eyes; anterior and posterior frontal fovea present (Fig. 70y–z); temples of male head depressed and projecting ventrally (Fig. 69); male neck ventrally with patch of long and dense setae at anteriorly (Fig. 69); female hind wings reduced to small pads; abdominal tergites IV–VI with discal carinae; genitalia broad and flattened (Fig. 70a–x).
KEY TO SPECIES OF THE INSIGNIS SPECIES- GROUP
