A new species, Caenorhinus (Flavodeporaus) guskovae Legalov, sp. nov. from Central Laos is described and illustrated. This new species is similar to C. (F.) nigrobasalis Legalov, 2003 from Vietnam but differs from it in the densely punctate pronotum, antennae extend behind humeri, forehead without a black band, black protibiae, and narrower rostrum. This is the third species of the subgenus Flavodeporaus of the genus Caenorhinus described from Laos.
