Draconarius anceps  sp. nov.

(Figs 37-43, 533)

Type material: Holotype. ♀, CHINA: Yunnan: Tengchong County: Houqiao, 16 km N of Danzha village at Zhaobitang Forest Park Station , N25.55771, E098.20885, 2500 m, May 29, 2006, D. Kavanaugh, R.L. Brett & D.Z. Dong, deposited in HNU ( CASENT9025594)GoogleMaps  .

Etymology: The species name is derived from Latin word “anceps”, which means "two-headed, double", and refers to the laterally extending diverticula on spermathecae, in addition to the spermathecal heads that extending anteriorly; adjective.

Diagnosis: This species seems to be similar to D. guoi  sp. nov. in having a similar atrium and triangular spermathecae, differing only in minor features in the female epigynum. This new species has a pair of short atrial ridges that are limited to the anterior part of the atrium (Fig. 37), while the atrial ridges of D. guoi  sp. nov. are long, extending posteriorly to the epigastric furrow (Figs 180-181).

Description: Female (holotype). Medium sized Coelotinae  , total length 8.90 (Fig. 41). Dorsal shield of prosoma 4.00 long, 2.20 wide; opisthosoma 4.90 long, 3.75 wide. AME smallest, approximately half the size of other eyes, which are subequal ( AME 0.10, ALE 0.18, PME 0.18, PLE 0.17); AME separated from each other by slightly less than their diameter, from ALE by half of AME diameter; PME separated from each other by about 2 /3 of their diameter, from PLE by slightly less than PME diameter (AME-AME 0.08, AME-ALE 0.05, ALE-PLE 0.08, PME-PME 0.12, PME-PLE 0.15, AME-PME 0.14) (Fig. 42). Chelicerae with 3 promarginal and 2 retromarginal teeth. Labium with length and width subequal ( L / W =1.00) (Fig. 43). Epigynal teeth absent; atrium small, with anterior atrial margin slightly protruding posteriorly; atrial ridges short, limited to anterior part of atrium; copulatory ducts indistinct from dorsal view; spermathecae short, broad, separated by slightly less than their width, with lateral diverticula; speramathecal heads distinct, arising anteriorly (Figs 37-40).

Male. Unknown.

Distribution: China (Yunnan: Tengchong) (Fig. 533).
