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.
