Aleochara (Rheochara) arachnipes FAUVEL, 1900 ( Figs 225-228)

Aleochara arachnipes FAUVEL, 1900: 248 f.

Type material examined:

Holotype ♂ [slightly teneral; dissected prior to present study; aedeogus missing]: "831 / Fl. Tschu / J. Sahlb. / arachnipes Fvl. / Type / Coll. R. I. Sc. N. B. / Holotypus ♂ Aleochara arachnipes Fauvel , rev. V. Assing 2009 / Aleochara arachnipes Fauvel , det. V. Assing 2009" ( IRSNB).

Comment:

The original description is based on a single specimen from "Turkestan: Ala-Tau" ( FAUVEL 1900). The species is similar to A. spadicea ( ERICHSON 1837) , but distinguished by more slender body ( Fig. 225), longer antennae with distinctly more slender antennomeres ( Fig. 227), a much less transverse and less convex pronotum ( Fig. 226), distinctly longer and especially more slender legs (metarsus approximately 1.2 times as long as metatibia; metatarsomere I approximately as long as the combined length of II and III), and shallower anterior impressions of abdominal tergites III-V ( Fig. 228).

So far, only the holotype of this species has become known.
