Key: Step 730. Orthocladiinae 142 Abiskomyia

730a. Anal segment very short: distance from base to tip of apical projections about 0.6 the total width of the segment; apical projections short (055f.jpg). Apical hooked points of segments IV and V with small bases, the point of the hooks mostly reaching beyond the base.

Abiskomyia virgo

730b. Anal segment longer: distance from base to tip of apical projections about equal to the total width of the segment; apical projections longer (055d.jpg). Apical hooked points of tergites IV and V with swollen bases and reduced hooks which generally do not reach to the anterior edge of the base, giving the appearance of a band of elongate granules, rather than hooks. 055-1.jpg species overview
