Philisca huapi , new species Figures 61H , 93C–E , 99

TYPES: Male holotype from Argentina, Neuquén province, Nahuel Huapi Natl. Park , Puerto Blest, Laguna Los Cántaros, ca. 41°00̍S, 71°50̍W, 30.I.1985, M. Ramírez, 9818, and female paratype from Puerto Blest, trail to Lago Ortiz Basualdo, I.1990, M. Ramírez, deposited in MACN­Ar.

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Resembles P. ornata (and oth­ er species not included here) in having anteriorly modified male chelicerae, but can be distinguished by lacking the lateral projections on the male endites and by the long, straight ducts of the female accessory bulbs.

FEMALE (paratype): Total length 5.05. Carapace length 2.10, width 1.48, wider on legs II–III. Length of tibia/metatarsus: I, 1.17/ 1.00; II, 0.98/0.88; III, 0.80/0.90; IV, 1.18/ 1.33. Palpal tarsus length 0.58. Chelicerae unmodified, with three teeth on retromargin, basal one largest. Sternum length 1.17, width 0.88. Spines: leg I, femur d 1–1–1, p 2ap; tibia v 2–2–2; metatarsus v 2bas. II, femur d 1–1–1, p d1ap; tibia v r1–2–2, p 0–1; metatarsus v 2bas, p 1. III, femur d 1–1–1, p and r d1ap; patella r d1; tibia v 0­ p1–2 or p1­ p1– 2, p and r d1–1–0, d r1bas; metatarsus v 2– 0­ p1 and apical group of hairs, p and r d1– 1–1, d 0­ p1–2. IV, femur = III; patella r d1; tibia v p1­ p1–2, p and r d1–1, d r1bas; metatarsus v 2­ p1­ p1 and apical group of hairs, p and r d1–1–1, d 0­ p1–2. Abdomen length 3.07, width 1.80, spiracle–epigastrium 1.70, spiracle–spinnerets 0.25. Color (fig. 99A): yellowish with grayish brown pattern. Legs with gray spots, patellae with spot on each side, tibiae with several basal spots and pair of apical spots. Margins of sternum and labium dark brown, endites brown. Abdomen yellow with white guanine reticulum, dorsum with park pattern, venter with median band dark brown from epigastrium to tracheal spiracle, two lateral lines of small spots. Anterior spinnerets different from those of males, slightly thickened at bases, without modified hairs. Epigyne weakly sclerotized, median field heart­shaped, ducts of accessory bulbs long, stright, slightly converging. Lateral lobes contiguous posteriorly (but slightly separate in some females, fig. 99D).

MALE (holotype): Total length 6.38. Carapace very wide in front, ocular area slightly protruding, length 2.30, width 1.57. Length of tibia/metatarsus: I, 2.17/1.97; II, 1.77/ 1.63; III, 1.15/1.30; IV, 1.63/1.87. Chelicerae very strong (fig. 99C), with internal superior margins slightly protruding in ridges. Three teeth on promargin, median one very thick, on elevation, other two small; three teeth on retromargin, basal one largest. Endites unmodified. Sternum length 1.13, width 0.95. Spines as in female, except: leg II, tibia v 2– 2–2. III, femur p 0­ d1­ d1 or 0­ d1–2; tibia v p1–2–2. IV, tibia v p1–2–2. Abdomen length 2.77, width 1.53, spiracle–epigastrium 1.30, spiracle–spinnerets 0.25. Base of anterior spinnerets globose, covered by thick, short hairs. Color (fig. 99B): similar to female. Palp (figs. 61H, 93C–E, 99E, F): tibia long, width/length 0.47. Embolus short, flattened, base globose, with longitudinal flat projecting ridge; basal process flattened, rounded. Median apophysis with series of thin branches (fig. 93C). Triangular sclerotized stripe runs from sperm duct to base of median apophysis. Paramedian apophysis wide, curved at tip. Primary conductor triangular, slightly flattened. Secondary conductor small, canal vestigial, limited to tip, ending in longitudinally ridged peak, on rounded projection directed backward; area basal to canal membranous; retrolateral portion wide, thin, elevated.

VARIABILITY: The size of male chelicerae is variable. The lateral epigynal lobes may be separate or contiguous. Spines: metatarsi III, IV, v 2­ p1­ p1.

NATURAL HISTORY: This species makes retreats on foliage. Most specimens were collected on bamboos ( Chusquea spp. ), and they resemble Gayenna americana , also common on the same bamboos. Notably, Platnickia elegans (Nicolet) ( Zodariidae ), which lives exclusively on bamboos (personal obs.), has a similar appearance too.

DISTRIBUTION: Humid southern forest in Chile, from Malleco to Palena provinces; in Argentina only collected in Puerto Blest and Termas de Epulaufquen, two humid Andean passes at the Chilean border.
