Batriscenellus admonitor

Yin, Zi-Wei, Li, Li-Zhen & Zhao, Mei-Jun, 2011, Batriscenellus Jeannel (Coleoptera, Staphylinidae, Pselaphinae) redefined, with notes on the Chinese species, Zootaxa 3016, pp. 37-50 : 39-40

1. Batriscenellus admonitor species group

Diagnosis. Abdominal tergite V with long setae dense at posteromedian margin, completely covering basomedian excavation of tergite VI, lacking lateral setiferous patches; with tuft of specialized setae at posteromedian margin of tergite VI ( Kurbatov, 1990: 73–74, fig. 2-a).

Remarks. Males of this group are similar to those of the B. fragilis group by sharing a median excavation of tergite VI which is covered by the apicomedian fringe of setae of tergite V. They can be easily separated by the lack of a pair of lateral setiferous patches on tergite V in the B. admonitor group, which are present on members of the B. fragilis group. Adults of the B. admonitor group may be readily separated from those of other groups by the distinctive setae at posteromedian margin of tergite VI.

This group includes only B. admonitor Kurbatov , which is endemic to the Russian Far East ( Kurbatov, 1990: 73; Löbl & Besuchet, 2002: 276.).
