Diagnosis and description.

See Deeleman-Reinhold (2001). Male palp as in Figs 44 , 59A , 69A , epigyne as in Figs 45A-D , 78F , 86F , 94F , habitus as in Fig. 45E-H .

Remarks.

Clubiona melanosticta and C. melanothele were considered separate species for more than 120 years. After examining the holotypes, Deeleman-Reinhold (2001) illustrated the two species and suggested that they could be conspecific; however, she made no taxonomic changes at the time. New material has been collected from Xishuangbanna containing both sexes. According to drawings of Deeleman-Reinhold (2001), the males were identified as C. melanosticta , and the females were identified as C. melanothele . Based on morphology (Fig. 45E-H ) and DNA barcoding data (Table 1 ), we matched the females and males together. Therefore, the two names are synonymised, and priority is given to C. melanosticta .

Distribution.

Thailand (Chiang Mai, Samut Songkram), Indonesia (Sumatra, Krakatau), New Guinea, Myanmar, Laos, China (Yunnan).
