Necrobiopsis Crowson

Necrobiopsis Crowson, 1964: 293; Crowson, 1970: 30.

Type species: N. tasmanica Crowson, 1964 (by original designation)

Individuals belonging to the genus Necrobiopsis are always distinctly smaller than those of Egolia, Acalanthis or Paracalanthis (less than 4.2 mm in length) and have a more flattened body, laterally denticulate pronotum and an eight-segmented antenna with a large, somewhat flattened antennal club vaguely divided into three parts. Crowson (1970) in his generic key incorrectly stated that the antenna was 7-segmented, probably based on his earlier figure of the antenna (Crowson 1964, fig. 30) which did not include the scape. The genus also resembles Larinotus Carter & Zeck (placed in a separate subfamily by Ślipiński, 1992 and separate tribe of Trogossitinae by Kolibáč, 2006), but that genus is distinguished by the more convex form, two-segmented antennal club, concealed protrochantins and lack of tibial spurs.
