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.
