For other synonyms and combinations see World Spider Catalog (2019).

Remarks: Nasoona asocialis was described from a female from the Nepal Himalayas and originally placed in Oedothorax (Wunderlich, 1974) . Later this species was described for a second time from a single male as Gorbothorax ungibbus Tanasevitch, 1998 from the same mountain region (Tanasevitch, 1998). The species is widely distributed in the Oriental Region: China, Nepal, India, Myanmar, Laos, Thailand, Malaysia (mainland), Indonesia (Bali, Java) (World Spider Catalog, 2019). Walckenaeria caobangensis was described on the basis of a female from Cao Bang Province, northern Vietnam (Tu & Li, 2004). The original description and figures of carapace, epigyne and vulva clearly show that W. caobangensis is conspecific with Nasoona asocialis and therefore a junior synonym. The synonymy is indirectly supported by the fact that N. asocialis is known from Xishuangbanna, southern China (Zhao & Li, 2014) and from northern Laos (Tanasevitch, 2014), territories close to the type locality of W. caobangensis . The species in known on Java from the Ijen Mts, 950 m a.s.l. (Tanasevitch, 2017a).

Range: Oriental.
