Legalov, A. A., 2020, NEW SPECIES AND NEW SUBGENUS OF THE GENUS COTASTEROMIMUS CHÛJÔ ET VOSS, 1960 (COLEOPTERA: CURCULIONIDAE) FROM THE PHILIPPINES, Far Eastern Entomologist 405, pp. 15-19 : 16

Genus Cotasteromimus Chûjô et Voss, 1960

Subgenus Cotasterorhinus Legalov , subgen. n.

http://zoobank.org/NomenclaturalActs/ccadf348-43c6-4540-ba8d-e6893ab99853

Type species: Cotasteromimus philippinensis Legalov , sp. n., here designated.

DIAGNOSIS. Rostrum bended at base, separated by impression from head. Antennal scrobes oblique, directed ventrally. Eyes transverse. Antennal club tomentose. Antennomere

9 almost two times shorter than antennomeres 10 and 11 combined. Scutellum distinct. Elytra subparallel. Humeri distinct. Elytral stria 9 not merges with stria 10 near metacoxa. Prosternum with postocular lobes and without rostaral channel bounded by carinae. Procoxal cavities narrowly separated. Sclerolepidia present. Abdominal process broadly truncate. Femora with large teeth. Metacoxae subglobular. Tarsomere 2 conical. Tarsomere 3 bilobed.

COMPARISION. Femora with or without teeth are a character of the genera in the tribe

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.

REMARKS. Cotasterorhinus subgen. n. belongs to the tribe Cotasteromimini based on the prosternum without a rostaral channel bounded by carinae, mandibles convergent, body convex, tarsomere 2 conical, metacoxae subglobular, abdominal process broadly truncate,

procoxal cavities narrowly separated, rostrum separated by an impression from the head, and the sclerolepidia present.

ETYMOLOGY. Subgeneric name from the generic name " Cotasteromimus " and the

Greek “rhinos” (nose). Gender masculine.
