Arkys walckenaeri

Arkys walckenaeri, Walckenaer's studded arkys, is a common Australian spider belonging to the family Arkyidae. A small ambush hunter with long curved forelegs and a narrow, triangular shaped abdomen, it is named in honour of Charles Athanase Walckenaer. It also occurs on Java.

Description
Arkys walckenaeri's triangular abdomen shows regional variability in colour and pattern. Specimens from Queensland and Java have white sigilla on an orange to red abdomen. West Australian, South Australian and Tasmanian specimens, on the other hand, are pale yellow with few to no visible markings. Both sexes reach a length of approximately 7 mm.
