25. misella species-group

(13 species)

Diagnosis. Members of the misella speciesgroup can be distinguished from other Sagola species-groups by the following combination of characters: body length 2.1–3.3 mm; antennomere 1 approximately 1.5–2.0 times longer than wide, male antennomeres enlarged; frontal rostrum rectangular, lobes continuous, reaching posterior frontal fovea (Fig. 59o); frontal sulcus reaching midpoint of eye, posterior frontal fovea present (Fig. 59o); female hind wings reduced to small pads; abdominal tergites IV–VI with discal carinae.

KEY TO SPECIES OF THE MISELLA SPECIES- GROUP
