Oxyopidae Hamadruas

Hamadruas sp. "Jogjakarta Batik"

Jogjakarta Batik Lynx Spider

The carapace shows one of the defining characteristics of a Hamadruas: a sloping profile in side view, higher in front and lower behind, with a weakly concave roof that has been described as a "shallow saddle". Like some other Hamadruas species in Southeast Asia, the basal two-thirds of the chelicerae (yellow arow) are covered densely by white setae; a dark purplish line runs on the underside femora I to III, and on the prolateral side of femora IV. seemingly analogous to the black lines seen in the legs of Oxyopes.

Mature females of this species may be distinguished from other Hamadruas by the elaborate green and brown motifs on the abdomen, like a certain Jogjakarta-style batik design. The suspected juvenile assumes a slightly different appearance, with a predominantly vivid orange abdomen decorated anteriorly with a backward-directed spear-like pattern, and posteriorly a long V-shaped marking, both outlined in green.
