Type material. Holotype male, 269 male and 34 female paratypes, VIETNAM: Ninh Binh Province, Cuc Phuong National Park (20º21.44’N, 105º34.21’E), March 2007 to March 2008, Dinh-Sac PHAM leg.

Etymology. The specific epithet is taken from the Latin adjective ‘ pumilus ’, referring to the body size of the new species.

Diagnosis. The new species is similar to Draconarius triatus (Wang & Zhu, 1994) , but can be distinguished from the by the following characters: 1, D. pumilus sp. nov. is significantly smaller than D. triatus , the former male body is 2.50–3.50mm long, the latter is 8.97–9.20mm long; 2, the cymbial furrow more than half of cymbial length in D. pumilus sp. nov., but about half of cymbial length in D. triatus ( Figs 52B, 55B); 3, the spermathecal heads thin, small, only seen from a dorsal view in D. pumilus sp. nov., but wide, large, seen from both ventral and dorsal views ( Figs 53B–C, 56B–C).

Description. Male. Total length 2.50–3.50. Holotype total length 3.20, prosoma 1.65 long, 1.05 wide; opisthosoma 1.55 long, 1.10 long. Eye measurements: AME 0.04; ALE 0.08; PME 0.08; PLE 0.08; AME– AME 0; AME–ALE 0; ALE–PLE 0; PME–PME 0.03; PME–PLE 0.01. Clypeus height 0.05. Leg formula: IV, I, II, III; leg measurements: I: 3.65 (1.05, 1.25, 0.80, 0.55); II: 3.15 (1.00, 0.95, 0.70, 0.50); III: 3.35 (0.85, 0.90, 0.70, 0.90); IV: 3.95 (1.20, 1.25, 1.05, 0.45). Chelicerae with five promarginal and five retromarginal teeth ( Fig. 52C). Patellar apophysis small ( Figs 52B, 55B); RTA occupying almost entire tibia length, distinctly extended distally, with distal end sharp ( Figs 52B, 55B); lateral tibial apophysis broad, close to the RTA ( Figs 52B, 55B); cymbial furrow more than half of cymbial length ( Figs 52B, 55B); conductor short and broad, with a navicular dorsal apophysis ( Figs 53A, 54B); median apophysis long, spoon-shaped ( Figs 52B, 53A, 54B, 55B); embolus long, filiform, proximal in origin ( Figs 53A, 54B).

Female. Total length 2.20–3.70. One of paratype total length 2.45, prosoma 1.00 long, 0.80 wide; opisthosoma 1.45 long, 1.00 wide. Eye measurements: AME 0.01; ALE 0.08; PME 0.06; PLE 0.06; AME–AME 0; AME–ALE 0; ALE–PLE 0; PME–PME 0.04; PME–PLE 0.01. Clypeus height 0.05. Leg formula: IV, I, II, III; leg measurements: I: 2.75 [1.00, 0.90, 0.50, 0.35]; II: 2.10 [0.50, 0.75, 0.50, 0.35]; III: 1.80 [0.60, 0.60, 0.35, 0.25]; IV: 2.55 [0.85, 0.85, 0.50, 0.35]. Chelicerae with five promarginal and five retromarginal teeth. Epigynal teeth small, situated posteriorly and laterally, widely separated ( Fig. 53B); atrium small, extremely close to epigastric furrow ( Fig. 53B); copulatory ducts long, situated between spermathecae ( Figs 53C, 56C); spermathecal heads can be seen from a dorsal view, but not from a ventral view, short and thin, situated anteriorly on spermathecae, widely separated ( Figs 53C, 56B–C); spermathecae large, rounded and slightly separated ( Figs 53C, 56B–C).

Habitat preferences. These specimens were collected by both pitfall traps and leaf-litter sieving, this species may live on the forest floor or in leaf litter.
