Cebrenninus Simon, 1887 (New to China)

Cebrenninus Simon, 1887: 468

Libania Thorell, 1890: 148 (synonymized by Simon, 1897: 9)

Ocyllus Thorell, 1887 (synonymized by Lehtinen, 2002: 316)

Cupa Strand , in Bösenberg & Strand, 1906 (Barrion & Litsinger, 1995: 208, misidentified)

Type species. – Cebrenninus rugosus Simon, 1887 , by original designation.

Diagnosis. – Medium sized thomisids. Cephalothorax: carapace convex, with many small apophyses and covered with many white hairs, lateral margins serrated. Chelicera with 2 promarginal and 2 retromarginal teeth, the larger retromarginal one bifid. Abdomen dorsum with small yellow spots and black markings. Male palp with a long RTA, bulb flat with slender embolus and median apophysis.

Remarks. – The genus includes 5 species recorded from Java, Sumatra and Borneo, but is poorly known because only the type species was simply illustrated by Simon (1897). This genus was misidentified by Barrion & Litsinger (1995) as Cupa (judging from his description and figures, the male palp of Cupa kalawitana has a long embolus and median apophysis, which is the typical diagnostic character of the genus Cebrenninus ). This genus is similar to Epidius (both of them have a small tooth and a large bifid tooth on the retromargin of chelicera), but can be separated from the latter by: ratio of width of ocular area / head area = 1.0 (0.5 in Epidius ); male palp has a spatulate VTA and a row of macrosetae (with VTA, RTA, sometimes with ITA in Epidius ).
