Two New Species of the Weevil Genus Mecysmoderes Schoenherr, 1837 (Coleoptera, Curculionidae: Ceutorhynchinae) from Vietnam

摘要

Two new species of the weevil genus Mecysmoderes Schoenherr, 1837 are described from Vietnam. Mecysmoderes ( Enzoellus ) vladimiri sp. n. differs from the type species of Enzoellus and its allies from Thailand and Laos in the larger size, deeper meshes on the pronotum, broader legs and a velvety black sutural spot on the elytra. Mecysmoderes ( Xenysmoderes ) sergii sp. n. in the shape, coloration, and vestiture of the body is similar to M. consularis Pascoe, but clearly differs in the larger size, strongly and unevenly convex pronotal disc, swollen in the middle part elytra, and a dark scutellar spot.
