03C6878B76398D31DEF94B8CC154FB4B.taxon	description	Cotasteromimini. The new taxon differs from the known species of the genus Cotasteromimus in the presence of distinct teeth on the femora, but it is very close to them; therefore, I describe a subgenus of this genus for it. Cotasterorhinus subgen. n. differs from Cotasteromorphus Kojima, 2005 with femoral teeth in the tarsomere 3 bilobed, large femoral teeth and distinct humeri.	en	Legalov, A. A.

03C6878B76398D34DFD24E80C1B8FE5F.taxon	description	DESCRIPTION. MALE. Body length (without rostrum) 3.8 – 4.7 mm. Rostrum length 1.2 – 1.3 mm. Body black, cowered with sparse narrow decumbent scales. Antennae, apices of tibiae and tarsi red-brown. Head spherical. Mandibles small. Rostrum bended at base, weakly curved from base to apex, narrowed to apex. Back of rostrum coarsely punctate, with three longitudinal carinas. Eyes large, transverse, not protruding from contour of head. Forehead flat, longer than rostrum base width. Antennal scrobes oblique, directed ventrally, not reaching eye for one third of rostrum. Antennae long, inserted at apical third of rostrum. Antennomere 1 long, not reaching eyes. Antennomere 2 conical. Antennomere 3 long-conical, longer and narrower than antennomere 2. Antennomeres 4 and 5 conical, significantly shorter and slightly wider than antennomere 2. Antennomeres 6 – 8 short-conical. Antennomeres 7 – 8 weakly dorsal view; 2 – paratype, aedeagus, dorsal view; 3 – paratype, aedeagus frontal view; 4 – holotype, habitus, lateral view. Scale bar = 1.0 mm for Figs 1 and 4, 0.5 mm for Figs 2 and 3. transverse. Antennal club distinct, tomentose. Antennomere 9 0.6 times as long as antennomeres 10 and 11 combined. Antennomere 10 shorter than antennomere 9. Antennomere 11 slightly longer than antennomere 10. Pronotum almost bell-shaped, slightly transverse. Disk flattened, sparsely and coarsely punctate. Distances between points narrower than diameter of points. Base angularly convex. Scutellum distinct. Elytra subparallel, narrowed at apical fourth laterally and uniformly convex dorsally. Humeri weak. Interstriae wide, slightly convex, almost smooth. Elytral striae distinct, with large and sparse points. Striae 9 not merge with striae 10 near metacoxa. Prosternum with postocular lobes. Pre- and postcoxal portions of prosternum long. Precoxal portion longer than postcoxal portion. Procoxal cavities distinctly separated. Metanepisternum very narrow, with row of large points. Mesocoxal cavities separated. Metaventrite convex, punctate, slightly longer than length of metacoxal cavity. Metacoxal cavities widely separated. Abdomen flattened, sparsely puncate. Ventrites 1 and 2 long, concave in middle. Ventrites 3 and 4 short, subequal in length. Ventrite 5 flat, longer than ventrites 3 and 4, with anal setae. Procoxae large, spherical. Femora and tibiae coarsely punctate. Femora weakly thickened, with large teeth. Tibiae weakly curved, with large uncus and two groups of setae at apex, with apical comb of setae oriented almost longitudinally along axis of tibia, without mucro. Tarsi long. Tarsomeres 1 – 3 conical. Tarsomere 2 shorter than tarsomere 1. Tarsomere 3 bilobed. Tarsomere 5 elongate. Tarsal claws free, without teeth. FEMALE. Body length (without rostrum) 4.5 – 4.7 mm. Rostrum length 1.1 mm. Rostrum more thicker. Precoxal portion of prosternum almost equal to postcoxal portion. Mesocoxae more separated. Ventrites 1 and 2 weakly concave, almost flattened. Ventrite 5 weakly convex. COMPARISION. The new species is similar to C. squamiger Morimoto et Miyakawa, 1985 but differs in the dentate femora, sparse and coarsely punctate pronotum, elytra in the apical quarter more strongly narrowed laterally and uniformly convex dorsally, and weakly rounded apex of the aedeagus. From C. morimotoi Chûjô et Voss, 1960 it differs in the dentate femora, narrower elytra with subparallel sides.	en	Legalov, A. A.
