Figs 10–14, 87

Type material. Holotype male, 1 male and 2 female paratypes, VIETNAM: Vinh Phuc Province, Tam Dao National Park (21º31.56’N, 105º33.15’E), 6 May 2003, Dinh-Sac PHAM leg.

Etymology. The specific epithet is taken from the Latin adjective ‘ perbrevis ’, referring to the significantly short embolus and conductor.

Diagnosis. The new species can be distinguished from other Coelotes species by the short conductor and embolus in male ( Figs 11A, 12B), and the oval-shaped, large copulatory ducts in female ( Figs 11C, 14C).

Female. Total length 10.50–11.00. One of paratype total length 10.50, prosoma 5.00 long, 4.15 wide; opisthosoma 5.50 long, 4.00 wide. Eye measurements: AME 0.15; ALE 0.28; PME 0.25; PLE 0.28; AME– AME 0.05; AME–ALE 0.08; ALE–PLE 0; PME–PME 0.10; PME–PLE 0.13. Clypeus height 0.23.

Epigynal teeth small, with sharp end, situated medially and laterally, widely separated ( Figs 11B, 14B); atrium small, oval-shaped, situated posteriorly ( Figs 11B, 14B); copulatory ducts large and oval-shaped ( Figs 11C, 14C); spermathecal heads broad, short, situated anteriorly, widely separated ( Figs 11C, 14C); spermathecal stalks long; spermathecal bases simple, small and close to each other ( Figs 11C, 14C).
