Recently this species was placed among the incertae sedis species of Pterostichus and treated as nomen dubium (CATPAL 1: BOUSQUET 2003d: 516). However, its systematic place was well-defined in the original description. GAUTIER DES COTTES (1870: 261-262) write: "Trés voisine de la Feronia (omaseus) fuscicornis ) (Reiche Nº 60) ou F. confusa (Chaud. En car. Du Caucase p. 136) - du Jourdan et du Caucase; elle en differe:…". The study of the two syntypes confirmed that this taxon has pronotum with convex sides backwards and posterior angles with small, protruding denticles. I consider that the differences noted by GAUTIER DES COTTES (1870: 262) do not merit specific rank so that this form is treated as conspecific with Pterostichus fuscicornis . The female syntype is selected for lectotype of F. similata because of the lacking last abdominal sterna and genitalia of the male syntype.

P. fuscicornis View in CoL is a distinct species with a wider distribution than expected. At present, it is known from Northeast Anatolia, Transcaucasus, Syria, Lebanon, Israel, Iran, and from eastern Tian Shan, Northwest China ( ANGUS et al. 2009). David Wrase wrote me "I have meanwhile received material also from Turkey (2 females: Rize, Kackar dagi and Mardin), though only females, they differ from P. nigrita View in CoL by not distinctly blackened appendages (dark rufopiceous), a somewhat flatter pronotum with a very fine lateral border/channel. I don't know if both species are exactly sympatric but I have a male of P. nigrita View in CoL also from the Kackar dagi, from a different locality, so at least they can occur both in the same region" (D. Wrase personal communication). For additional notes on the nomenclature of P. fuscicornis View in CoL see WRASE (1992) and ANGUS et al. (2009).
