description: Draconarius turriformis sp. nov.
Figs 16–20 and 21
Type material: Holotype male, one female paratype, CHINA: Yunnan Province, Xishuangbanna Dai Autonomous Prefecture, Mengla County, Menglun Natural Reserve, Secondary tropical seasonal moist forest (21º54.607’N, 101º17.005’E, Alt: 633m), 23 October 2006, Guo ZHENG leg.
Etymology: The specific epithet is taken from the Latin adjective ‘ turriformis ’, referring to the tower– shape spermathecae of female epigyne; adjective.
Diagnosis: The new species can be distinguished from other Draconarius and Coelotes species by the following characters: 1, conductor wide and long, extending beyond the median apophysis, with the proximal margin branching distally (Figs 17 A, 18B); 2, embolus filiform, thick proximally and slender distally (Figs 17 A, 18B); 3, patellar apophysis distinctly large (Figs 17 A, 18B); 4, spermathecae large, tower–shaped (Figs. 17 C, 20C).
Description. Male (measurements of the holotype): Total length 7.00. Prosoma length 3.75, width 2.75; Opisthosoma length 3.25, width 2.35. Eye measurements: AME 0.25; ALE 0.38; PME 0.35; PLE 0.38; AME– AME 0; AME–ALE 0.05; ALE–PLE 0; PME–PME 0; PME–PLE 0.15. Eyes pale, AME slightly reduced, the tubercles of eyes not reduced. Clypeus height 0.20. Leg formula: IV, I, II, III; leg measurements: I: 12.50 (3.40, 4.15, 3.20, 1.75); II: 11.85 (3.50, 3.70, 3.00, 1.65); III: 8.90 (2.75, 2.35, 2.65, 1.15); IV: 12.30 (3.50, 4.00, 3.45, 1.35). Chelicerae with three promarginal and two retromarginal teeth (Fig.16 C). Patellar apophysis large, twice the patellar length (Figs 17 A, 18B); RTA with blunt distal end (Figs 16 B, 19B); lateral tibial apophysis small, situated close to RTA (Figs 16 B, 19B); cymbial furrow longer than half of cymbial length, with the distal end widely separated from the cymbium (Figs 16 B, 19B); conductor wide and long, extending beyond the median apophysis, with the proximal margin branching distally, conductor dorsal apophysis small, slightly curved distally (Figs 17 A, 18B); median apophysis large, spoon–shaped (Figs 16 B, 19B); embolus filiform, thick proximally and slender distally, originating proximally (Figs 17 A, 18B).
Female (measurements of paratype): Measurements: Total length 6.75. Prosoma length 3.40, width 2.30; Opisthosoma length 3.35, width 2.35. Eye measurements: AME 0.20; ALE 0.30; PME 0.30; PLE 0.30; AME–AME 0; AME–ALE 0.10; ALE–PLE 0; PME–PME 0; PME–PLE 0.20. Eyes white, AME slightly reduced, the tubercles of eyes slightly reduced. Clypeus height 0.20. Leg formula: IV, I, II, III; leg measurements: I: 8.05 (2.25, 2.75, 1.85, 1.20); II: 7.50 (2.25, 2.50, 1.75, 1.00); III: 6.00 (1.85, 1.90, 1.50, 0.75); IV: 8.40 (2.75, 2.75, 2.00, 0.90). Chelicerae with three promarginal and two retromarginal teeth.
Epigynal teeth small, situated posteriorly and laterally, widely separated (Figs 17 B, 20B); atrium small, shallow, situated posteriorly (Figs 17 B, 20B); copulatory ducts large, originating posteriorly (Figs 17 C, 20C); spermathecal heads small, situated anteriorly, originating from copulatory ducts, widely separated (Figs 17 C, 20C); spermathecae large, tower–shaped and slightly separated (Figs 17 C, 20C).
Distribution: Only known from Menglun Natural Reserve of Xishuangbanna Dai Autonomous Prefecture in Yunnan Province in China (Fig 13).
Remarks: The long cymbial furrow, large spoon–shaped median apophysis, long embolus, large and posteriorly originated copulatory ducts and strongly convoluted spermathecae suggest this species may be a member of genus Draconarius, but a large patellar apophysis suggests that this species may belong to the genus Coelotes. Meanwhile, both of these two genera are not monophyletic now, so we tentatively place this species in genus Draconarius.
