Chinophrys trifasciata sp. nov.

Figs 1–6

Holotype: male, SOUTH AFRICA, Western Cape Province, Cape Town, Table Mountain, Cecilia , Rooikat Ravine , 33°59'S: 18°24'E, Afrotemperate forest , antifreeze pitfall trap, 23 May 2008 — 21 February 2009, leg. C. Uys ( NCA 2011 /847).

Paratypes: same data as holotype, 1 male ( NCA 2008 /2918) ; same data, 1 male ( NCA 2008 /2911) .

Diagnosis. This species is distinguished from other euophryines by the unique form of the chelicerae, with multicuspid teeth ( Fig. 3 ). The structure of the palpal organ is similar to that in the genus Euophrys , but the embolic disc is larger. C. trifasciata differs from Asian species of this genus by the shape of the embolus and the proximal tegular lobe.

Etymology. The specific name refers to the colouration of the “cheeks” with three white stripes.

Description. Measurements. Cephalothorax: length 1.5–2.2, width 1.0–1.5, height 0.6–1.1. Abdomen: length 1.2–2.4, width 0.9–1.2. Eye field: length 0.6–1.1, anterior width 0.9–1.4, posterior width 0.8–1.3.

Male. General appearance as in Fig. 1 . Carapace moderately high, dark brown, with median lighter stripe. Ocular area dark brown, almost black. Anterior eyes surrounded by small white scales, some brown bristles near first row of eyes. Sternum yellowish brown. Clypeus low, brown with white stripe at base of chelicerae. Three parallel lines composed of white hairs on “cheeks”, below anterior lateral eyes ( Fig. 2 ). Chelicerae brown, proximal parts covered with long white hairs, promargin with four teeth, retromarginal tooth broad, with five to seven cusps ( Fig. 3 ). Abdomen yellowish grey (mosaic of grey stains on light background), dorsum with black scutum covering half of abdomen (sometimes scutum poorly visible), venter also spotted. Legs dark brown, tarsi lighter. First pair bigger than others, patellae, tibiae and metatarsi with dense brown hairs ventrally. Three pairs of ventral spines on first tibia. Pedipalps yellow, covered with white hairs and sparse dark brown bristles ( Fig. 2 ). Embolic disc large, bulb with long proximal lobe ( Fig. 4 ), cymbium with small tutaculum (ear-shaped process at base on retrolateral side) ( Fig. 5 ), retrolateral tibial apophysis simple and triangular ( Figs 4–6 ).

Female unknown.

Distribution. Known only from Table Mountain in the Western Cape, South Africa.

Remarks. This is the first species of this genus discovered in Africa.
