Figs 6–10 and 21

Type material: Holotype male, 33 male and 54 female paratypes, CHINA: Yunnan Province, Xishuangbanna Dai Autonomous Prefecture, Mengla County, Menglun Natural Reserve, Primary tropical seasonal rain forest (21º57.445’N, 101º12.997’E, Alt: 744m), 3 October 2006 to 27 July 2007, Guo ZHENG leg.; 2 male and 21 female paratypes, Menglun Natural Reserve, Secondary tropical seasonal moist forest (21º54.984’N, 101º16.982’E, Alt: 656m), 3 October 2006 to 27 July 2007, Guo ZHENG leg.; 16 male and 9 female paratype, Menglun Natural Reserve, Secondary tropical seasonal rain forest (21º55.428’N, 101º16.441’E, Alt: 598m), 3 October 2006 to 27 July 2007, Guo ZHENG leg.

Etymology: The specific epithet is a Latin adjective, referring to the type locality.

Diagnosis: The new species is similar to D. exiguus sp. nov. in having the similar conductor ( Figs 7 A, 8B, 12A, 13B), the long embolus ( Figs 7 A, 8B, 12A, 13B), the similar cymbial furrow in male ( Figs 6 B, 11B, 9B, 14B), and in having a small atrium in female ( Figs 7 B, 10B, 12B, 15B), but can be distinguished from the latter by the absence of media apophysis ( Figs 6 B, 9B, 11B, 14B), the absence of lateral tibia apophysis ( Figs 6 B, 9B, 11B, 14B), the relatively larger atrium in comparison with the latter ( Figs 7 B, 10B, 12B, 15B), the absence of epigynal teeth ( Figs 7 B, 10B, 12B, 15B) and the small spermathecal heads ( Figs 7 C, 10C, 12C, 15C). These two new species can be distinguished from the other Draconarius species by the following characters: 1, conductor dorsal apophysis curved distally, with sharp distal end ( Figs 6 B, 9B, 11B, 14B); 2, cymbial furrow more than half of cymbial length, with distal margin distinctly dark ( Figs 6 B, 9B, 11B, 14B); 3, atrium small ( Figs 7 B, 10B, 12B, 15B).

Epigynal teeth absent ( Figs 7 B, 10B); atrium small ( Figs 7 B, 10B); copulatory ducts not visible from the dorsal view ( Figs 7 C, 10C); spermathecal heads small, situated anteriorly, widely separated ( Figs 7 C, 10C); spermathecae simple, almost global, strongly convolving, close together ( Figs 7 C, 10C).

Distribution: Only known from Menglun Natural Reserve of Xishuangbanna Dai Autonomous Prefecture in Yunnan Province in China ( Fig. 21 ).
