Diagnosis . Coelotes iriei sp. nov. resembles C. decolor Nishikawa, 1973 ( q.v. ) in having a pale body, a broad and strongly curved conductor of the male palpus, and minute epigynal teeth, but can be distinguished from the latter species by the genital structure. The embolus of the male palpus of C. iriei becomes thin and spirally curved towards the tip, but that of C. decolor is not spiral. The epigynum of C. iriei is deeply hollowed in its posterior portion exactly as in cybaeid spiders, but that of C. decolor is not hollow. Description . Holotype (male) . Total length 11.5; carapace 5.8 long, 4.0 wide; abdomen 5.7 long, 3.3 wide; sternum 3.0 long, 2.3 wide. Eye sizes: AME 0.15, ALE 0.23, PME 0.20, PLE 0.25. Distances between eyes: AME–AME 0.10, AME–ALE 0.10, PME–PME 0.15, PME–PLE 0.23, AME–PME 0.15, ALE–PLE 0.08. MOA: anterior width 0.40, posterior width 0.55, length 0.50. Leg measurements: I, 18.3 (4.8, 6.1, 4.5, 2.9); II, 16.3 (4.4, 5.3, 4.0, 2.6); III, 15.3 (3.9, 4.7, 4.2, 2.5); IV, 21.0 (5.4, 6.4, 6.1, 3.1). Cheliceral promargin with three teeth on left and four on right, and both retromargins with two teeth. Palpus ( Fig. 3E, F ): patellar apophysis short; LTA absent; RTA broad; cymbial furrow elongated, about half as long as cymbial length; median apophysis large, spoon-like; conductor broad, spiraled with one loop; embolus enlarged, deeply grooved at origin in lateral view, irregularly crooked, and pointed at tip. Coloration: carapace yellowish brown, with brown radial flecks; dorsum of abdomen gray, with indistinct chevrons; sternum yellowish brown; chelicerae and labium brown; maxillae reddish brown; leg I brown, leg II yellowish brown, legs III and IV yellowish grey; legs lacking ring flecks. Female ( allotype ) . Total length 12.2; carapace 5.3 long, 3.3 wide; abdomen 6.9 long, 4.1 wide; sternum 2.5 long, 2.1 wide. Eye sizes: AME 0.13, ALE 0.23, PME 0.18, PLE 0.20. Distances between eyes: AME–AME 0.10, AME–ALE 0.13, PME–PME 0.15, PME–PLE 0.25, AME–PME 0.10, ALE– PLE 0.08. MOA: anterior width 0.36, posterior width 0.51, length 0.41. Leg measurements: I, 14.6 (4.1, 5.0, 3.3, 2.2); II, 13.2 (3.7, 4.3, 3.2, 2.0); III, 12.7 (3.4, 3.9, 3.4, 2.0); IV, 17.2 (4.6, 5.3, 4.9, 2.4). Cheliceral promargin with three teeth and retromargin with two. Epigynum and endogynum ( Fig. 3G, H ): atrium small but deeply hollowed; epigynal teeth thin, minute, situated on central plate of epigynum; spermathecal head transparent, visible as single blackish-brown dot at anterior region of epigynum; spermathecae long, X-shaped, connected to spermathecal heads and fertilization ducts; copulatory ducts broad, oval-shaped, medially overlapping each other. Coloration of carapace and abdomen almost same as that of male holotype ; leg I brown, leg II yellowish brown, legs III and IV yellowish grey; legs lacking ring flecks. Distribution . Kumamoto , Kagoshima , and Miyazaki Prefectures ( Fig. 4 ). Etymology . The specific name, a noun in the genitive case, is dedicated to Mr. Teruo Irie, who discovered this new species in 2003. Remark . The coloration and the epigynal form of the new species are dissimilar from those of the type species of Coelotes . It is, nonetheless, placed in Coelotes because its most closely related species, Coelotes decolor , is also classified in this genus ( Nishikawa 1973 ).
