Park, J. - S. & Carlton, C. E., 2014, A revision of the New Zealand species of the genus Sagola Sharp (Coleoptera: Staphylinidae: Pselaphinae: Faronitae), The Coleopterists Bulletin (mo 13) 68, pp. 1-156 : 102-103

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

The key is based on male specimens because most female specimens are indistinguishable based on external morphology.
