Talaus niger
Tang et al., 2008
c: 65, figs 13-23.
Type material examined.
Paratype
.
2 ♀ (GKJ020): CHINA, Yunnan Province, Tengchong County, Wuhe Township, Tongjiazhuang Village, Longchuanjiang River (Longjiang Bridge), along river,
24.89284°N
,
98.67439°E
, 1210 m, 24 May 2005, Heng-mei Yan & Ke-ji Guo leg. (Tho-202). Holotype not examined.
Diagnosis.
The female can easily be recognized by the S-shaped copulatory ducts with a swollen median part (Fig.
3D
).
Description.
Female habitus as in Fig.
3A, B
, epigyne in Fig.
3C, D
.
Epigyne
: copulatory openings relatively large, antero-medially located, with sclerotized and round margins; epigynal hood posteriorly located, thumb-like; copulatory ducts S-shaped, anterior part relative narrow, L-shaped, medial and posterior part swollen, extending transversally; spermathecae triangular, widely separated by approximately half of their width; fertilization ducts located posteriorly, directed anteriorly.

Distribution.
Known only from the type locality in Yunnan Province, China (Fig.
12
).
Remarks.
According to
Tang et al. (2008
: 65), the original materials consisted of a male and two females, one female deposited in HNU and one female in CAS. However, two females and no male holotype were found in HNU and there are no labels designating the paratypes. Based on the locality information and the original illustration given in their paper, these specimens can be confirmed as the paratypes of
T. niger
and have been labelled as such. They are somewhat shriveled after alcohol evaporated during storage, but their epigynes still can be clearly recognized after pancreatin digestion and are now placed on labelled slides.
