Dendryphantes fulvipes. Galiano, 1980: 36.
Material examined. CHILE: 1♀, 1km S Matil R., Valdivia, Chile, 26 February 1988, L. Pena, G.B. Edwards, Nothofagus forest, (BJR861, FSCA).
Diagnosis. Cephalothorax black with white pennate hairs on sides. Abdomen black with a white pennate anterior border, no markings. Insemination ducts medium length passing over the dorsal surface of the small spermathecae which touch in the mid-line.
Description. Male (after Mello-Leitao 1943): Cephalothorax medially elevated, thoracic region sloping, long deep thoracic groove/furrow situated just behind posterior eyes. Ocular area as wide as the cephalothorax, length and posterior breadth almost equal, broader behind. Clypeus almost absent. Chelicera vertical. A single smaller blunt promarginal tooth and a single very robust, sharp and straight retromarginal tooth. Endites weakly broadened on their distal external angle, where a small, short, pointed apophysis is present. Labium longer than wide. Sternum twice as long as broad, slightly narrowed in front. Abdomen elliptical, dorsal surface weakly convex, black, with a narrow anterior border clothed in white pennate scales. Front legs notably more robust than others, with femur expanded, tibia thick and cylindrical, metatarsus approximately equal in size to tibia. Tibiae armed with 2-2-2 short, erect ventral spines, metatarsus armed with 2-2 ventral spines, larger and recumbent. L2 thin, tibia armed with only one ventral spine, centrally placed, metatarsus with 2-2-0 ventral spines. L3 and L4 unarmed. Cephalothorax, chelicerae, labium, endites and sternum black with purplish tones. Palps and legs pale mahogany. Palp: with black bulb, very large and prominent, embolus small, comma-shaped. Dimensions: L1 2.9 (0.8+1.2+0.5+0.4); L2 2.0 (0.6+ 0.8+0.35+0.25); L3 2.0 (0.6+0.7+0.4+0.3); L4 3.0 (0.9+1.1+0.6+0.4).
Female: Small relative to other species in the genus. Cephalothorax black grading to very dark brown near fovea. White pennate hairs on sides below anterior lateral eyes grading into the clypeal fringe. Clypeus narrow, with long white fringe twice the depth of the clypeus. Chelicerae slightly geniculate, black to dark tan, with two small promarginal teeth and one large, curved retromarginal tooth (Fig. 27). Endites dark brown. Labium yellow and sternum dark brown. Abdomen rounded (but dried out in specimen), covered with midgrey mat of hair overlaying brown surface with lighter pennate edge around the anterior third (Fig. 26). Spinnerets mid-brown. Ventral abdomen same as dorsal surface of the abdomen. L1: robust, femur, patella, tibia and tarsus dark brown, metatarsus lighter brown. Other legs mid-brown, with scattered dark markings, spines less distinctive. Spines: L1 femur one dorsal and two distal dorsolateral spines, tibia three pairs of ventrolateral spines, metatarsus two pairs of ventrolateral spines, L2, tibia single ventrolateral spine, metatarsus two pairs of ventrolateral spines, L3& L4 without spies. Epigynum (Figs 28–29): sclerotised, with two anterior fossa oriented towards each other and with distinctive, well separated copulatory openings. Insemination ducts medium length passing over the dorsal surface of the small spermathecae which touch in the mid-line (Fig. 28). Dimensions: CL 28, EFL 13, CW 19, AEW 16, AMEW 10, PEW 18, AL (dried out).
Distribution and biology. Known from type from ‘Santiago’ and from Valdivia in Nothofagus forest, so likely to be widespread.
