Type material. Holotype male, 110 male and 1 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; 89 male paratypes, VIETNAM: Vinh Phuc Province, Tam Dao National Park (21º31.56’N, 105º33.15’E), March 2007 to March 2008, Dinh-Sac PHAM leg.

Etymology. The specific epithet is taken from the Latin adjective ‘ longissimus ’, referring to the long cymbial furrow and long embolus.

Diagnosis. The male of this new species can be distinguished from other Draconarius species by extremely long cymbial furrow and long embolus ( Figs 35B, 36A, 37B, 38B). The female of this new species is similar to D. clavellatus sp. nov., but can be distinguished from the latter by the absence of spermathecal heads and the different copulatory ducts ( Figs 36C, 39B).

Description. Male. Total length 4.75–6.75. Holotype total length 6.25, prosoma 3.00 long, 2.15 wide; opisthosoma 3.25 long, 2.30 wide. Eye measurements: AME 0.05; ALE 0.13; PME 0.13; PLE 0.13; AME– AME 0; AME–ALE 0; ALE–PLE 0; PME–PME 0.05; PME–PLE 0.04. Clypeus height 0.13. Leg formula: IV, I, II, III; leg measurements: I: 9.45 (2.65, 3.00, 2.30, 1.50); II: 8.10 (2.35, 2.60, 1.95, 1.20); III: 7.25 (2.05, 2.25, 1.95, 1.00); IV: 9.70 (2.50, 3.25, 2.75, 1.20). Chelicerae with three promarginal and two retromarginal teeth ( Fig. 35C). Patellar apophysis small ( Figs 35B, 38B); RTA occupying almost entire tibia length ( Figs 35B, 38B); lateral tibial apophysis broad, close to the RTA ( Figs 35B, 38B); cymbial furrow long, almost as long as the cymbial length ( Figs 35B, 38B); conductor simple, extremely broad, with large lamella and small dorsal apophysis ( Figs 35B, 36A, 37B, 38B); median apophysis long, spoon-shaped ( Figs 35B, 36A, 37B, 38B); embolus extremely long, filiform, retrolateral in origin( Figs 36A, 37B).

Female. Total length -. prosoma 2.35 long, 1.50 wide; opisthosoma length -, width -. Eye measurements: AME 0.05; ALE 0.13; PME 0.13; PLE 0.13; AME–AME 0.01; AME–ALE 0; ALE–PLE 0; PME–PME 0.04; PME–PLE 0.03. Clypeus height 0.13. Leg formula: IV, I, II, III; leg measurements: I: 5.60 [1.50, 2.00, 1.20, 0.90]; II: 4.60 [1.35, 1.50, 1.00, 0.75]; III: 4.05 [1.25, 1.25, 1.00, 0.55]; IV: 5.80 [1.70, 2.00, 1.50, 0.60]. Chelicerae with three promarginal and two retromarginal teeth. Epigynal teeth extremely small, with sharp end, situated posteriorly and laterally, widely separated ( Figs 36B, 39A); atrium reduced, line-shaped ( Figs 36B, 39A); copulatory ducts long, extending anteriorly and enlacing the spermathecae ( Figs 36C, 39B); spermathecal heads absent ( Figs 36C, 39B); spermathecae large, rounded and close together ( Figs 36C, 39B).

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

Distribution. Vietnam (Ninh Binh, Vinh Phuc) (Fig. 89).
