Remarks. According to the type pictures of Sthenias semicylindricus Hayashi, 1974 (Figs. 20-21), it is similar to A. medioalbus (Breuning, 1956) (Figs. 18-19), by the body shape, elytral apex shape, antennal segments, main pubescence maculae on elytra, with differences on irregular grayish white spots over pronotum and elytra. However, the pair of type specimens were obviously rubbed, which was the reason of lacking the white spots. Compared with a fresh specimen from Taiwan (Fig. 7 by Holzschuh & Lin 2013) and specimens from Fujian (Fig. 19), we cannot find differences between the two taxa, so we propose the synonymy. This is agreed by Carolus Holzschuh (personal communication). However, Wen-Xuan Bi proposes a more complicated opinion, that all the records of A. dorsalis from Mainland China were misidentifications, and all of them, including the Anaches medioalbus from Fujian, should be Anaches albonotatus Pic, 1932. We agreed with Wen-Xuan Bi that the specimens in IZCAS we examined are not the true A. dorsalis and we re-identify them as A. medioalbus (Breuning, 1956) in this paper. To clarity the true identity of A. albonotatus described from northern Vietnam (Tonkin) it needs more study.
Holzschuh (2021) synonymized Sthenias murzini Lazarev, 2020 with Sthenias dorsalis Pascoe, 1858, which is the type species of the genus Anaches Pascoe, 1865. However, Anachus murzini (Lazarev, 2020) is not a synonym of A. dorsalis (Pascoe, 1858), because it is much closer to A. medioalbus (Breuning, 1956) than to A. dorsalis (Pascoe, 1858), which has been misunderstood for a long time. The true A. dorsalis (Pascoe, 1858) is endemic to India and nearby. We understood that the “ A. dorsalis ” in Holzschuh (2021) is infact A. medioalbus in this paper, and we agreed with him on the variations of elytral maculae and the shape of elytral apex both are infrasubspecific features, therefore we synonymized A. murzini (Lazarev, 2020) with A. medioalbus (Breuning, 1956) herein.
