FIGURES 9–12. Coelotes thailandensis Dankittipakul & Wang, 2003 . Male holotype (11), male (12) and female (9–10) from Doi Inthanon. Epigyne (9) and its internal structures (10). Palpal patellae and tibiae, retrolateral view (11–12). Scale lines: 0.25 mm (9–10), 0.5 mm (11–12). Remarks. The male holotype of C. thailandensis was described from an evergreen forest in Chiang Rai Province but the corresponding female was then not known. Later, Ramirez & Grismado collected males and females of Coelotes on Doi Inthanon, approximately 100 km away from the type locality of C. thailandensis . The palp of one of the males examined by Ramirez & Grismado ( Fig. 12 ) resembles that of the holotype of C. thailandensis ( Fig. 11 ) except for its distinctively shorter patellar apophysis. We consider this difference as intraspecific variation. Recently we collected a female specimen in the same area and believe that it also belongs to C. thailandensis . It is described in the following and can be recognized by an elongate epigynal atrium ( Fig. 9 ) and by a strongly sclerotized internal genital structure with thickened ducts ( Fig. 10 ).

Cheliceral groove with 3 promarginal and 4 retromarginal teeth. Leg formula 4123 (23.56, 22.50, 19.75, 17.79). Leg measurements: femora: I 5.34, II 4.96, III 4.55, IV 5.80; patellae: I 1.38, II 1.10, III 0.99, IV 1.41; tibiae: I 6.90, II 5.81, III 5.15, IV 7.11; metatarsi: I 5.68, II 5.03, III 4.85, IV 6.33; tarsi: I 3.20, II 2.85, III 2.25, IV 2.91. Epigyne ( Figs 9–10 ): posterior margin slightly concave; atrium longitudinally elongate; epigynal teeth small, situated laterally, relatively far away from each other; internal structure strongly sclerotized; copulatory ducts indistinct (the anteriorly extended ends of the spermathecae might be the copulatory ducts); spermathecae short and thick; fertilization ducts of normal shape. Natural history. Coelotes thailandensis inhabits evergreen hill forests between 1400 m and 1680 m . The male holotype was collected from an irregular sheet­web in a rotten log. The female was collected from a PVC tube ( 3 cm diameter) on the forest floor. Distribution. Known from the provinces of Chiang Mai and Chiang Rai, northern Thailand .
