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.
