Dendryphantes villarrica . 39–40 dorsal view (39 female, 40 male); 41–42 chelicera (41 female, 42 male); 43–44 female genitalia (43 dorsal view of cleared specimen, 44 ventral view); 45 lateral view of cephalothorax showing positions of large prominances behind anterior and posterior lateral eyes, 46–47 male palp (46 ventral view, 47 lateral view), 48 known distribution. Scales: total body 1mm; remainder 0.2mm Diagnosis. Cephalothorax and dorsal abdomen dark brown, latter with white margin on anterior third and a white spot halfway down each side of the abdomen in females ( Fig. 39 ). Spermatheca touch in the midline with insemination ducts passing ventrally ( Fig. 43 ). Description. Male ( paratype from Santiago): Cephalothorax dark orange-brown, its lower margin grading to black. Surrounds of ALE, PME and PLE, black. Clypeus narrow, without a fringe. Chelicerae geniculate, tan, with one large and one smaller promarginal teeth and one very large straight retromarginal tooth. Endites dark brown grading to yellow. Labium and sternum brown. Abdomen mid-brown with white edge around the anterior third. Without a white spot half way down each side ( Fig. 40 ). Spinnerets mid-brown. Ventral abdomen same as dorsal surface of the abdomen. L1: robust, femur, patella, tibia, tarsus and metatarsus mid-brown. Other legs pale yellow, 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 femur one dorsal and two distal dorsolateral spines, tibia single ventral spine, metatarsus two pairs of ventrolateral spines, L3 femur one dorsal and two distal dorsolateral spines, tibia no spines, metatarsus one pair of ventrolateral spines, L4 femur two dorsal and two distal dorsolateral spines, tibia one ventral spine, tarsus one pair of ventrolateral spines. Palp ( Figs 46–47 ): tibia with single small apophysis. Tegulum with small distal lobe next to the embolus but without a proximal lobe, embolus small and blunt.

Female ( holotype ): Cephalothorax dark orange-brown, its lower margin grading to black. Surrounds of ALE, PME and PLE, black ( Fig. 39 ). Clypeus narrow, with light grey fringe. Chelicerae geniculate, tan, with two promarginal teeth and one medium-sized straight retromarginal tooth. Endites dark brown grading to yellow. Labium and sternum dark brown. Abdomen mid-brown with white edge around the anterior third. White spot half way down each side ( Fig. 39 ). Spinnerets mid-brown. Ventral abdomen same as dorsal surface of the abdomen. L1: robust, femur, patella, tibia and tarsus dark brown, metatarsus yellow. Other legs pale yellow, with longitudinal 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 femur one dorsal and two distal dorsolateral spines, tibia two pairs of ventrolateral spines, metatarsus two pairs of ventrolateral spines, L3 and L4 femur one dorsal and one distal dorsolateral spines, tibia no spines, metatarsus one pair of ventrolateral spines. Epigynum ( Figs 43–44 ): sclerotised, with two anterior fossa oriented towards each other and with distinctive, well separated copulatory openings. Insemination ducts medium length passing under the ventral surface of the small spermathecae with a posterior ventral turn.
