Type species

Polydrusus kahri Kirsch, 1865

Diagnosis

A new subgenus of Polydrusus Germar, 1817 , similar to Conocetus , especially in the broad rostrum and the shape of the antennal scrobes (see Introduction), but differing in: (1) all femora toothed (untoothed in Conocetus ) and (2) internal sac consisting of a tissue with rasp-like teeth and a simple, clip-shaped sclerite as shown in Fig. 9A–C . In Conocetus the internal sac consists of a complex “wrench”-shaped

sclerite, see Fig. 9D–P , whereas in Eustolus the internal sac consists of several differently shaped, complex sclerites, and in the rather heterogeneous Polydrusus s. str. the internal sacs consist of prevailing tissues with rasp-like teeth.

Etymology

The subgeneric name Denticonocetus subgen. nov. is of male gender and combines the characteristically dentate femora (in Latin: dentis = tooth) and the morphologically most similar subgenus Conocetus .
