Description
(Figs. 40A–C)
Type series. Holotype female, unnamed creek Bansadon Trail, Inobong, Crocker Range, Borneo, Malaysia, 5º 51.456 N 116º 0 8.403 E, alt. 436 m asl, 18-ix-2012 (RMNH).
Diagnosis. Idiosoma rounded; fourth coxae medially pointed, not forming parallel medial margins; gonopore relatively slender and long; legs with few swimming setae.
Description. Female: Colour yellowish, anteriorly pale red. Idiosoma rounded, 365 long dorsally and 344 wide, ventral length 381. Dorsal shield 308 long and 288 wide. Anterior coxae extending beyond anterior idiosoma margin. Coxal field elevated over ventral shield, Cx-III/-IV with subparallel, anteriorly slightly diverging lateral margin. Fourth coxae medially pointed, not forming parallel medial margins. Genital plates indistinct, with numerous small acetabula (> 20 pairs). Gonopore relatively slender and long, 87 long and 68 wide. Length of P1- P5: 20, 44, 27, 50, 19; palp rotated, P3 anteromedially and P4 medially with a long seta each. Length of I-leg-4–6: 34, 48, 44. Length of IV-leg-4–6: 58, 68, 54. III-leg-4 with a long stiff seta, III-leg-5 and IV-leg-5 with one short swimming seta each. Excretory pore terminal.
Male: Unknown.
Etymology. Named after the pointed fourth coxae.
Remarks. Africasia insulana K. Viets, 1935 from Lake Toba on Sumatra, similar in the shape of Cx-IV, is larger, has many more swimming setae, a more rounded gonopore and a higher number of acetabula. The Indian Africasia species described by Cook (1967) differ in Cx-IV with parallel medial margins. Africasia cataphracta (Haliík, 1930) from mainland Malaysia agrees in size and the elongated gonopore, but has more swimming setae, wider first coxae and the medial margin of Cx-IV less pointed.
Distribution. Borneo; known only from the locus typicus.
