Genus Uroballus Simon, 1902

Diagnoses of genera of South East Asia: Uroballus (3-3. 5; ?). Elsewhere (3; 3-3.5). This is another salticid genus having a very wide cephalothorax. However, it differs from others in this group by having very long, thin spinnerets, particularly the anteriors. The cephalothorax is somewhat flat and broad, almost square with rounded comers. The abdomen is elongate oval, widely rounded at the front and pointed at the rear. Legs I are thick, short and have very swollen femora. The other legs are much weaker. For the single female U. peckhami from Vietnam the carapace is dark orange with eye area becoming blackish anteriorly and having two dark spots. On the lateral lere are numerous white hairs that stick out. The underlying colour of the abdomen is light grey and carries a dark grey spine-like pattern followed by chevrons posteriorly. The legs are yellow with grey annulations near the joints. The long spinnerets are light grey.
Distribution: Uroballus is known only from Sri Lanka, Vietnam and possibly Borneo. Murphy & Murphy 2000: 289. By courtesy of the Authors' and the Malaysian Nature Society.
