Cupa kalawitana Barrion & Litsinger, 1995: 208 , Figs. 119a–f (new synonymy, types not examined)

Material examined. – 1 male (HNU-Hu 060901), Qinglangdang (27º41'N 98º17'E), 1,309 m, Dulongjiang Township , Gongshan County, Yunnan Province, China, coll. P. Hu, 1 Sep.2006 .

Diagnosis. – The species is the type species of the genus Cebrenninus , which can be separated from the allied species by: the tibia only with one large RTA, the bulb flat, and the embolus and median apophysis both long and spatulate, the apex of median apophysis curved .

Description. – Male. Total length 4.64. Carapace 2.25 long, 2.12 wide; abdomen 2.39 long, 1.88 wide. Carapace dark brown, slightly swollen, with some small apophyses and some short white hairs, lateral margins serrated with curved spines Cervical grooves, radial grooves and fovea distinct. Eye area wide, eye tubercles indistinct, eye sizes and interdistances: ALE (0.16)> PLE (0.14)> PME (0.06)> AME (0.04); AME-AME (0.14) <AME-ALE (0.15), PME-PME (0.25) <PME-PLE (0.32), MOA long (0.37), back (0.40)> front (0.29). Sternum brown. Chelicerae, gnathocoxae, labium blackish brown. Legs I, II dark brown; legs III, IV brown, all femora with annuli and 2 dorsal spines; femora I slightly swollen medially, ventrally and prolaterally with some denticles, prolaterally with 5 spines; tibiae I, II with 5 pairs of long ventral spines; metatarsi I, II with 2 pairs of spines; tibiae III, IV with 3 pairs of ventral spines; metatarsi III with 2 pairs of ventral spines; metatarsi IV without ventral spines. Leg measurements: I 7.90 (2.50, 3.20, 1.20, 1.00), II 8.20 (2.60, 3.30, 1.30, 1.00), III 5.70 (1.80, 2.10, 1.10, 0.70), IV 6.10 (1.90, 2.20, 1.20, 0.80); formula 2, 1, 4, 3. Abdomen nearly oval with short hairs, dorsum with black markings and small light brown spots. Its sides with black lines; venter yellow. Palpal tibia with large RTA, the apex of RTA sharp and slightly curved; bulb flat, sperm ducts visible within tegulum, both the embolus and the median apophysis long and spatulate, the apex of median apophysis curved in beak-shaped.

Female. No fresh female specimen was examined.

Distribution. – Java, Sumatra, Borneo, Thailand, Malaysia, the Philippines; China (Gongshan County, Yunnan Province).

Remarks. – This species is widely distributed from South Asia to China (including Thailand and Malaysia ( Benjamin, 2008)). After compared the descriptions and figures of Cebrenninus rugosus Simon, 1887 , and Cupa kalawitana Barrion & Litsinger, 1995 (types not examined), both male palps have a long embolus and median apophysis, which indicates that Cupa kalawitana Barrion & Litsinger, 1995 , should be considered as a junior synonym of Cebrenninus rugosus Simon, 1887 .
