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.

来自越南的 Imachra Pascoe, 1874 属的两个新种 (Coleoptera: Curculionidae)
本报告描述了来自越南 Hòa Bình 省的 Imachra Pascoe, 1874 属的两个新种。Imachra (Orchestoides) zinchenkoi sp. n.与 Imachra shirozui (Morimoto, 1964) 的不同之处在于:前胸宽,后背更粗壮,胫骨、股骨和喙黑色,前胸条纹密布,前胸没有三条鳞片,后背没有鳞片和基底下斑块。Imachra (Orchestoides) colonnellii sp. n.与 Imachra nipponica (Morimoto, 1964) 的不同之处在于:身体黑色,前胸和后背板没有鳞片斑块和条纹,喙较长,前胸先端明显侧弯。这是越南 Imachra 属的首个记录。
