28. insignis View in CoL 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 View Fig ) and female head bluntly triangular, widest across eyes; anterior and posterior frontal fovea present ( Fig. 70y–z View Fig ); temples of male head depressed and projecting ventrally ( Fig. 69 View Fig ); male neck ventrally with patch of long and dense setae at anteriorly ( Fig. 69 View Fig ); female hind wings reduced to small pads; abdominal tergites IV–VI with discal carinae; genitalia broad and flattened ( Fig. 70a–x View Fig ).
KEY TO SPECIES OF THE INSIGNIS SPECIES- GROUP
