Two new species of genus Imachra Pascoe, 1874 (Coleoptera: Curculionidae) from Vietnam

Abstract

Two new species of the genus Imachra Pascoe, 1874 are described from the Hòa Bình Province, Vietnam. Imachra (Orchestoides) zinchenkoi sp. n. differs from Imachra shirozui (Morimoto, 1964) in the wide pronotum, more robust elytra, black tibiae, femora and rostrum, densely punctate elytral interstriae, pronotum without three stripes of scales, elytra without postscutellar patch of scales and subbasal patches. Imachra (Orchestoides) colonnellii sp. n. differs from Imachra nipponica (Morimoto, 1964) in the black body, pronotum and elytra without patches and stripes of scales, longer rostrum and distinctly laterally curved apex of the aedeagus. It is the first record of the genus Imachra for Vietnam.
