Draconarius clavellatus sp. nov.

Figs 24–28, 87

Type material. Holotype male, 120 male and 1 female 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 ‘ clavellatus ’, referring to the claviform median apophysis.

Diagnosis. The male of new species is similar to Draconarius pseudoclavellatus sp. nov., but can be distinguished from the latter by the following characters: 1, the conductor extends proximally to the median apophysis in this new species ( Figs 25A, 26B), the conductor does not extend all the way to the median apophysis in D. pseudoclavellatus sp. nov. ( Figs 44B, 46B); 2, the conductor dorsal apophysis thin, claviform in this new species ( Figs 24B, 27B), but not in D. pseudoclavellatus sp. nov. ( Figs 47B, 45B); 3, the patellar apophysis longer and rounded distally in this new species ( Figs 25A, 24B, 26B, 27B), but shorter and acuminated distally in D. pseudoclavellatus sp. nov. ( Figs 44B, 45A, 46B, 47B). The males of these two new species can be distinguished from other Draconarius species by the uniquely claviform median apophysis which is extending transversely ( Figs 25A, 26B, 44B, 46B). The female of this new species is similar to D. longissimus sp. nov., but can be distinguished from the latter by the presence of spermathecal heads and the different copulatory ducts ( Figs 25 B–C, 28B–C).

Eye measurements: AME 0.08; ALE 0.15; PME 0.13; PLE 0.13; AME– AME 0; AME–ALE 0; ALE–PLE 0; PME–PME 0.05; PME–PLE 0.03. Clypeus height 0.15. Leg formula: IV, I, II, III; leg measurements: I: 10.05 (2.50, 3.25, 2.60, 1.70); II: 8.30 (2.20, 2.55, 2.15, 1.40); III: 7.85 (2.25, 2.25, 2.05, 1.30); IV: 10.45 (2.70, 3.25, 3.00, 1.50). Chelicerae with three promarginal and two retromarginal teeth ( Fig. 24C). Patellar apophysis long and thin ( Figs 24B, 27B); RTA occupying almost entire tibia length, distinctly extended distally ( Figs 24B, 27B); lateral tibial apophysis broad, close to the RTA ( Figs 24B, 27B); cymbial furrow long, more than half of the cymbial length ( Figs 24B, 27B); conductor simple, with extremely extending posterioly and reaching the median apophysis, conductor dorsal apophysis thin, claviform ( Figs 24B, 25A, 26B, 27B); median apophysis long and claviform, with extending transversely ( Figs 25A, 26B); embolus long, filiform, retrolateral in origin ( Figs 25A, 26B).

Female. Total length 5.85. prosoma 2.60 long, 2.00 wide; opisthosoma 3.25 long, 2.25 wide. Eye measurements: AME 0.08; ALE 0.15; PME 0.15; PLE 0.15; AME–AME 0; AME–ALE 0; ALE–PLE 0; PME– PME 0.05; PME–PLE 0.03. Clypeus height 0.15. Leg formula: IV, II, III; leg measurements: I: - [-, -, -, -]; II: 7.35 [2.00, 2.50, 1.75, 1.10]; III: 6.70 [1.80, 2.10, 1.80, 1.00]; IV: 9.15 [2.40, 3.00, 2.50, 1.25]. Chelicerae with three promarginal and two retromarginal teeth. Epigynal teeth extremely small, with sharp end, situated posteriorly and laterally, widely separated ( Figs 25B, 28B); atrium reduced, line-shaped, slightly close to epigastric furrow ( Figs 25B, 28B); copulatory ducts large, extending anteriorly and covering the distal parts of spermathecae ( Figs 25C, 28C); spermathecal heads short and small, originating from spermathecae laterally and medianly, widely separated ( Figs 25C, 28C); spermathecae large, rounded and close together ( Figs 25C, 28C).

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