Salticidae Psenuc

Psenuc nuclearis (Prószyński, 1992)

Saw-lined Braille Jumper

The dark-coloured body of the male is covered with long and appressed (flattened) white setae, leaving only a pair of blackish brown parallel bands over the carapace, and a median serrated (saw-like) band over the abdomen. The white setae on the body are easily rubbed off, thereby revealing the darkly coloured integument of the carapace. [See page xxx for a frontal view of a male.] There is a rarer morph (body form) of this species whose body is covered almost entirely by white setae, interspersed with some orangish and brown setae as shown in the upper right picture.

Length♀ 4–6 mm; ♂ 5–6 mm, 4 mm in "white" morph
DistributionSingapore, Malaysia (Johor, Perak, Sarawak), Marshall Islands.
HabitatRocks or coral rubble in intertidal zone, but found also in degraded habitat inland.
