Anterior coxal cavities closed behind. Prosternal process narrow near the base, posterior three-fourths strongly diver- gent apically, widest part about twice as much as narrowest part; apex of the process deeply, triangularly excavate. Punc- tation of metasternum rather fine at medium part and very strong at lateral parts. Legs relatively stout. All tarsi with bilobed 1st, 2th, and 3th segments. 1st segment of posterior tarsi weakly elongated, little than 3 times as long as width. 4th segment very little, indistinctly visible. Tibia without thorns and spikes. Membranous wings fully developed. DISTRIBUTION. Russian Far East, China (Hubei). REMARKS. The unique proportions of body, elytral shape and structure of anterior pronotal corners make this new species being quite different from other congeners. C. kurbatovi sp.n. is compared with C. quadrimaculatus and C. integer: C. kurbatovi: elytra 1.241.33 as long as combined width; C. quadrimaculatus: elytra 1.51.68 as long as com- bined width; C. integer: elytra 1.51.76 as long as combined width. C. kurbatovi: humerus of elytra with a strong denticle; C. quadrimaculatus: humerus of elytra with a strong denticle; C. integer: humerus with a weak denticle. C. kurbatovi: anterior margin of pronotum bisinuate; C. integer: anterior margin of pronotum without sinuate. C. integer: 1st segment of posterior tarsi strongly elongate, more than 3 times as long as width. ETHYMOLOGY. Named in honour of S.A. Kurbatov. Fig. 1. General view of Cryptophilus kurbatovi sp.n.
