Common Diamond-bellied Crab Spider
This is the most common Angaeus species in Singapore, easily recognised by the thinner wing-like pattern on the dorsum of mature females, compared to the more moustache-like design in mature females of A. lenticulosus and A. verrucosus, and also in immature females of A. rhombifer. The wing-like pattern is less apparent in the males.
A. rhombifer is not as palely coloured as A. lenticulosus, principally because the curly hairs that clothe the body are shorter and less dense. Although some A. rhombifer individuals may be as darkly coloured as A. verrucosus, they may be distinguished from the latter by the absence of curly white hairs seen only on tibiae IV of A. verrucosus.
