Cyclocosmia latusicosta, new species (Figs. 3-6) Holotype. – Female, Aidian Village (21°49'N 107°18'E), Ningming County, Guangxi, China, coll. M. S. Zhu, J. X. Zhang and F. Zhang, 25 Aug.2004. Paratypes. – 4 females, same data as for the holotype. Diagnosis. – The new species is similar to Cyclocosmia ricketti, especially in the shape of its spermathecae, but differs from the latter by the spermathecae being two times longer than wide (Figs. 6 F-J), abdominal disc with 20/23 ribs on each side, and each upper muscle impression with an elevated central zone (Fig. 6B). It is also similar to Cyclocosmia siamensis Schwendinger, 2005 (Schwendinger, 2005: 231, figs. 9-30, pl. 1C) in the shape of spermathecae, but differs from the latter in the upper and median pair of muscle impressions on opisthosomal disc separated by one transversal rib, all ribs lacking hairs with dark, short, cylindrical, upright proximal portion and light, long, flat, reclining distal portion, abdominal disc with 20-23 ribs on each side, and each upper muscle impression with an elevated central zone (Fig. 6B). Description. – Female. Holotype total length, including chelicerae, 33.56; chelicerae 4.50 long; carapace 12.78 long, 11.25 wide; abdomen 17.20 long, 16.38 wide. Carapace black-brown and smooth, with a few hairs and four long bent bristles in longitudinal row running through ocular area. Carapace curved in front and straight behind, widest at coxae III. Ocular area darker in color. Cervical groove and radial furrows distinct. Fovea deep and procurved, U-shaped, its greatest width occupying one fifth of carapace width at that point. Eyes (Fig. 6A) set on low tubercle, ocular area 1.25 long, 3.06 wide anteriorly, 3.09 wide posteriorly, occupying one third of carapace width at that point. Clypeus height 1.80. Anterior eye row straight and posterior eye row slightly recurved, both rows subequal in width. Ratio of eyes, ALE: AME: PLE: PME (0.75: 0.51: 0.54: 0.37). ALE-AME 0.40, AME-AME 0.27, PLE-PME 0.08, PME-PME 1.39. MOA 1.05 long, 1.29 wide ... |
