Diagnosis.

A species of Geophilus with head ~ 1.2 × as long as wide; antennal articles ≤ 2 × as long as wide; second maxillary pretarsus claw-like, longer than surrounding setae; forcipular trochanteroprefemur ~ 1.5 × as long as wide; forcipular trochanteroprefemur, femur, and tibia without denticles; tarsungulum bearing a small basal denticle; 37-61 leg-bearing segments; “carpophagus” pits absent; ventral pore-fields present, an entire transverse posterior band on the anterior metasternites, two paired posterior groups on the posterior metasternites; metasternite of ultimate leg-bearing segment wider than long; up to a dozen coxal pores on each coxopleuron, all close to the margin of metasternite; pretarsus of ultimate leg pair claw-like; anal pores present.

Distribution.

Western Siberia: Tomsk oblast (Nefediev et al. 2017a). Eastern Siberia: Zabaykalsky krai (Gerstfeldt 1859, as Arthronomalus longicornis). Outside Asian Russia: Western Palaearctic (e.g., Bonato et al. 2005; Stoev 2007).

Remarks.

The record from Western Siberia seems to be due to anthropochore introduction (Nefediev et al. 2017a), while the record from Eastern Siberia requires confirmation (see Discussion).
