modicatus bukejsi ssp. nov.

Female unknown. Differential diagnosis. Regarding the shape of the body, the new subspecies is similar to the nominative subspecies C. modicatus modicatus Holzschuh 1995 , from which it can be distinguished by the different arrangement of spots in elytra: one transverse spot, two larger symmetrical spots and two smaller spots, connected by a shorter longitudinal dark line (C. m. modicatus with two larger and two smaller symmetrical spots in elytra.

Etymology. This subspecies is named after my colleague Dr. Andris Bukejs (Daugavpils University, Daugavpils, Latvia) in appreciation of cooperation, and in gratitude for his contribution to the studies of fossil Coleoptera from the Baltic amber.

Note. Currently, two subspecies of C. modicatus Holzschuh 1995 have been described: C. m. modicatus Holzschuh 1995 ( Fig. 2 ) from Yunnan, China and C. m. tristriatus Holzschuh 1995 from Laos (Tavakilian, Chevillotte 2020).
