urn:lsid:zoobank.org:act:15B1A726-F663-4A12-9AD8-DA0925B29BC2

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 .
