Neoperlops cheni ( Wu, 1938)

Tetropina cheni Wu, 1938 — Wu 1938: 206. (original description of the male from Guangxi); Claassen 1940: 170. (catalog); Illies 1966: 300. (catalog).

Neoperlops cheni ( Wu, 1938) — Zwick 1984: 173. (comb. n., note on the similarity with N. gressitti ); Sivec et al. 1988: 40. (synopsis); Du et al. 1999: 61 (checklist); Stark & Sivec 2008: 94. (note on possible conspecific with N. gressitti ); Yang & Li 2018: 32. (catalog); DeWalt et al. 2020. (catalog).

Distribution. China, Guangxi Zhuang Autonomous Region, Lo Ch’eng. Previously known only from the holotype male, which is lost ( Wu 1938a, Zwick 1984).

Remarks. Zwick (1984) noted that only on the basis of the original description, this species is indistinguishable from N. gressitti . Despite that this is the only species hitherto known from Guangxi, below we report our gressitti group specimen as N. gressitti . Wu (1938, figs. 308–309) originally illustrated an undivided sensilla basiconica patch on tergum 9, probably a species specific character of Neoperlops . Our specimen has a divided sensilla patch, similar to the redescription of N. gressitti ( Zwick 1984: fig. 2d). However, topotypes need to be examined from Luocheng City (Lo Ch’eng) to clarify this the status of this species.
