Based on a study of collection material, the leaf beetle Cryptocephalus cunctatus Clavareau, 1913 is recorded in the Russian fauna for the first time. The beetle was collected in southern Eastern Siberia, in Chita Region. Its discovery in Russia was anticipated, as the species is known from Central Mongolia and northeastern China. The article provides images of the habitus, details of the external morphology, and the aedeagus. This species exhibits a number of morphological characteristics typical of the subgenus Sopidus. However, the structure of protarsomere 1 and the form of the aedeagus suggest its assignment to the subgenus Homalopus.
