Taxonomy. The species was mistakenly listed by Wood and Bright (1992) and Knížek (2011) as a synonym of Hypothenemus tristis (Eichhoff) in the tribe Cryphalini . The taxonomic position of the species was clarified by Beaver (2012). RAB has examined the holotype (IRSNB) of D. apatoides from Japan, one specimen in NHML from Japan, and two in RAB from Taiwan ( Beaver 2012), and compared the latter with the description and photographs of the holotype of Taphrorychus striatus Nobuchi. It is clear that only a single species is represented. The species is distinguished from all other species of Dryocoetiops except D. salebrosus by the subcostate interstriae on the elytral declivity. It can be distinguished from D. salebrosus by the characters given in the key above.

Distribution. China (Yunnan), Japan, Taiwan, Vietnam.
