description: Draconarius bannaensis sp. nov.
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).

Patellar apophysis small, with blunt distal end (Figs 6 B, 9B); RTA large and extending beyond tibia (Figs 6 B, 9B); lateral tibial apophysis absent (Figs 6 B, 9B); cymbial furrow more than half of cymbial length, with distal margin distinctly dark (Figs 6 B, 9B); conductor simple, conductor dorsal apophysis strongly curved distally, with sharp distal end (Figs 7 A, 8B); median apophysis absent (Figs 6 B, 9B); embolic base almost triangular; embolus filiform, long and slender, originating proximally (Figs 7 A, 8B).
Female (measurements of paratypes): Measurements: Total length 5.70–7.20. Prosoma length 2.60– 2.85, width 1.65–2.00; Opisthosoma length 3.10–4.35, width 2.15–2.75.

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