Abstract

A group of the species closely related to Chrysopilus subaquilus and distributed in the eastern regions of Russia is considered. Two new species are described. Ch. leleji is closely related to Ch. kurenzovi Kriv. et Sid. Its tergites II-V are blackish brown at their bases, not paler than the others; sternite VIII is broad and rectangular; tergite IX forms a distinct cone-shaped opening. Ch. paradoxus is similar to Ch. subaquilus Nag., but its clypeus is red, not brown. In addition, this species differs distinctly from all the known species of this genus in the presence of lateral tubercles on tergite IX. The main morphological characteristics of Ch. subaquilus Nag., Ch. lilianae Sob., and Ch. yezonis Nag. are analyzed.
