Three new generic records and descriptions of four new species of jumping spiders (Araneae, Salticidae) from Sri Lanka Author Nilani Kanesharatnam Author Suresh p.

This species is close to the female of H. laurae Peckham & Peckham, 1903 , but differs in the shape of the spermathecae and presence of accessory glands. Etymology The speciFc epithet refers to the type locality.

Labium yellowish brown with black margin. Sternum oval with black colored spots in middle, edges reddish brown. Vicinity of eyes blackish brown and slightly elevated. Front eyes covered with long dark brown bristles. First eye row slightly curved upward. Eye Feld comparatively longer than in congeners, occupying about half the length of prosoma ( Fig. 5 A). Median ocular quadrangle much broader than long. White hairs interspersed on lateral sides of prosoma. Prosoma high, longer than wide. Narrow fovea in midline of prosoma behind PLEs. Lateral and posterior sides of prosoma almost vertical and posterior margin slightly truncated. Abdomen: Rounded, smaller and narrower than prosoma. Dorsum with yellowish brown small dots on anterior portion, comparably large pair of yellowish brown spots at midpoint, transverse pale yellow stripes extending laterally as dashed line at posterior half ( Fig. 5 A). Venter with longitudinal pale yellow dashed-line pattern from spinnerets to epigastric furrow. Spinnerets dirty yellow. LEGS. All legs yellow with black lateral bands. Tibia I with 3 spines on prolateral and 3 spines on retrolateral sides. PALP. Yellowish brown palp with black hairs. Palpal tibia short. Retrolateral tibial apophyses with minute tooth-like structures at tip (serrated), strongly curved retrolaterally ( Figs 5 C–D, 6 A–B). Long cymbium narrowing toward tip. Bulbus elongated. Tegulum long with a large and broad proximal lobe extending posteriorly up to half of the palpal tibia. Embolus cone-shaped with slightly curved blunt tip, originating from under tegular ledge ( Figs 5 C, 6 A). Part of the spermophor clearly visible at shoulder of tegulum. Female MEASUREMENTS.

COLOR AND BODY. All characters are as in males except all legs dark brown without the distinguishable bands found in males, sternum light brown in middle with dark brown edge. EPIGYNUM. Wide sclerotized pocket-like vaginal roof with shallow notch at posterior edge near epigastric furrow. Large copulatory openings like windows situated posterolaterally ( Figs 5 E–F, 6 C–D). Curved accessory glands with pin-like structures at the tip ( Fig. 6 D). Copulatory ducts short. Peculiarly shaped, heavily sclerotized spermathecae with thick walls. Fertilization ducts narrow arising from anterodorsal side of receptacles ( Fig. 6 D).
