A new species of the genus Pterostichus Bonelli, 1810 (Coleoptera: Carabidae) from the Russian Far East

Abstract

Pterostichus (Phonias) neglectoides sp. n. is described from the Jewish Autonomous Region, Russia. New species is similar to P. neglectus A. Morawitz, 1862 but differs from latter in the structure of endophallus, and colouration of palps and legs.

A new synonym of the ground beetle Pterostichus bandotaro Tanaka, 1958 (Coleoptera: Carabidae)

“…Although the species described in his study has become a synonym, the results of Budilov (2022) are important from at least two perspectives. First, his results, together with those of the present study, constitute the first record from continental Asia of P. bandotaro, a species thought to be endemic to the Japanese Archipelago (Bousquet, 2017).…”

“…His specimens were collected from an inland area along the Amur River. Considering the continuity of the habitat, it is assumed that P. bandotaro is also distributed in the continental area located between Budilov's (2022) collection sites and the Japanese Archipelago, and further distribution surveys are expected. In that case, the endophallus morphology described in his and my studies serves as a reliable diagnostic character.…”

“…Taxonomic studies for Pterostichus are ongoing at both the species and subgenus level. Recently, Budilov (2022) described a new species of this genus, Pterostichus neglectoides, from the Jewish Autonomous Region, Russia. He considered P. neglectoides to be a new species based on comparisons with related species from the Russian Far East, especially P. neglectus Morawitz, 1862, which is markedly similar in external appearance.…”

“…After examination of the original description, I noticed that P. neglectoides Budilov, 2022 is conspecific with P. bandotaro Tanaka, 1958, described from Japan. In this short report, I treat the former as a synonym of the latter and discuss the importance of the results of Budilov (2022). DISTRIBUTION.…”

“…1 -head and pronotum, dorsal view; 2 -endophallus, left lateral view; 3 -endophallus, dorsal view; 4endophallus, right lateral view. Terminology used for the endophallus structures (A-G) follows that of Budilov (2022). Scales: 1.0 mm.…”
