Diagnosis: Male of this smallish salticid is easily recognised by its slender, orange abdomen with black apex and spinnerets and female by having a distinct dorsal pattern formed by dark, squamous hairs.
Description: Rather small salticid (TL=4.8-5.9, CL=2.19, CW=1.51); female larger than male due the bigger abdomen. Carapace of both sexes orange brown, ocular area densely cowered with squamous, dark brown hairs. Legs pale yellowish. Male abdomen narrow, cowered with squamous, orange hairs; dark lateral stripes on anterior part; apex and spinnerets black. Female abdomen with distinct pattern of dark, squamous hairs. Tibia of male palp with bifid apophysis. Bulbus disk-like; long, whip-like embolus starting from its posterolateral part, running around it, ending close to tip ofcymbium. Epigyne with narrow, median ridge, deeply V-shaped notched anteriorly; openings of fertilising ducts on either sides of posterior part; on both sides of duct openings close to epigastric furrow dark, medially opening arches.
Distribution: Previously know only from Solomon Islands. This is the first record of the species from Seychelles and has been found on Bird and Mahé.
Discussion: Previously only one female specimen was known of this species. Epigyne figures were presented by
Kulczynski (1910)
and
Proszynski (1984)
. Epigynes of my specimens correspond to them closely. Th e male is described here for the first time.
