Figs 1–4

Pterostichus (Badistrinus) bandotaro Tanaka, 1958: 78 (type locality: “Lake Wadanuma in the river-bed of the Toné, Chiba Pref., Honshu, Japan” [Bentenshita, Kashiwa-shi, Chiba

Prefecture, Japan; the Wadanuma Lake disappeared due to land reclamation and no longer exists.]; Bousquet, 2017: 71.

Pterostichus (Phonias) neglectoides Budilov, 2022: 25 (type locality: the protected zone of

‘Bastak’ Reserve, the Jewish Autonomous Region, Russia). Syn. n.

MATERIAL EXAMINED. Japan: Honshu, Tochigi Prefecture, the Watarase Wetland,

26–28.IV 2006, 1♂; the same locality , 26–28.IV 2013, 1♂, 4♀; the same locality, 6–8. V

2013, 4♀; in the collection of KS.

DISTRIBUTION. Japan (Honshu, Hokkaido), Russia (Jewish Autonomous Region).

NOTES. The endophallus structure of P. neglectoides illustrated by Budilov (2022) is completely identical to that of P. bandotaro in its overall shape, as well as the position, shape and chitinization of lobes on the endophallus surface. The external morphology of the two is also identical in terms of body size, overall shape, surface punctures, and chaetotaxy. Based on these results, I conclude that P. neglectoides should be synonymized with P. bandotaro .

pronotum, dorsal view; 2 – endophallus, left lateral view; 3 – endophallus, dorsal view; 4 –

endophallus, right lateral view. Terminology used for the endophallus structures (A–G) follows that of Budilov (2022). Scales: 1.0 mm.
