Aysenoides colecole , new species Figures 26 , 28 , 35B

TYPES: Male holotype (in MHNS) and one male paratype (in MACN­Ar 9809) from Chile, Región X, Chiloé province, Isla de Chiloe´, Arroyo Cole Cole, 25 km N Cucao, ca. 200 m, ca. 42°30̍S, 54°11̍W, 8– 11.II.1991, M. Ramírez.

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

DIAGNOSIS: Resembles A. terricola in body shape and genitalia, but can be distinguished by having two epigynal pouches with their openings directed forward, and by a shorter cusp of the paramedian apophysis on the primary conductor.

FEMALE (Antillanca, fig. 28D): Total length 5.30. Carapace length 1.87, width 0.93, wid­ er at leg II. Length of tibia/metatarsus: I, 0.88/0.81; II, 0.74/0.69; III, 0.43/0.51; IV, 0.90/0.69. Palpal tarsus length 0.39. Chelicerae with 3 strong teeth on retromargin, basal one larger. Sternum length 0.97, width 0.58. Spines: leg I, femur d 1–1–1, p d1ap; tibia v 2–2–2 (the x­p1­ x slightly displaced prolaterally); metatarsus v 2bas. II, femur = I; tibia v r1­ r1–2, p 0–1; metatarsus = I. III, femur d d1­ d1­ d1, p and r d1ap; tibia v r1ap, p d1–1 or 0–1, r 0–1; metatarsus v r1–0–2, p 0­ d1–1, r 1ap, d 0­ p1–2. IV, femur d 1–1– 1; tibia v 0­ p1–2, r 0–1; metatarsus v 2­ p1– 2, p 1ap, r d1–0–1, d 2ap. Leg III directed forward. Femora II and III narrow, IV very strong. Abdomen length 3.40, width 1.27, spiracle–epigastrium 2.10, spiracle–spinnerets 0.16. Color: carapace and legs grayish, posterior legs paler. Abdomen yellow with grayish stripes; dorsum with median stripe on anterior half, two lateral ones; epigastrium grayish, venter with median stripe from epigyne to spinnerets. Dark arch­shaped mark surrounding spinnerets ventrally and laterally. Epigyne (fig. 28E, F): median field sclerotized, longitudinal median ridge close to lateral pouches. Limit between lateral lobes and median field unclear anterior to copulatory openings. Two lateral pouches with openings directed forward, apparently formed by elevated margins of lateral lobes. Spermathecae spherical, accessory bulbs voluminous, contiguous.

MALE (holotype): Total length 5.45. Carapace length 2.13, width 1.15. Length of tibia/metatarsus: I, 2.00/1.80; II, 1.30/1.23; III, 0.64/0.82; IV, 1.27/1.13. Chelicerae slightly narrower than those of female, with more evenly spaced teeth. Sternum length 1.09, width 0.61. Spines as in female, except: leg I, p 1­ d1­ 1­ 0; metatarsus p d1–0 or 0­ d1­ 0­ 1. I I, tibia p 1­ d1­ 1­ 0, v r1–2–2; metatarsus p d1­ d1­ 0­ d1. III, femur r 0­ d1­ d1; tibia v 0­ r1–2 or 0­ p1–2, r 1­ d1­ 1­ 0; metatarsus v 2– 0–2, p d1­ d1–1, r 0­ d1–1. IV, femur r d1ap or 0; tibia v p1–2–2, r 1­ d1­ 1­ 0. Abdomen length 3.27, width 0.93, spiracle–epigastrium 1.97, spiracle–spinnerets 0.13. Color as in female, with abdominal stripes darker, except median stripe, diffuse. Palp (figs. 26, 28A– C): tibia width/length 0.77, RTA very long, thin. Cymbium relatively small, globose, cymbial conductor wide. Tegulum basal. Sperm duct with two conspicuous loops at dorsal anterior margin, one at base of secondary conductor. Embolus with basal process long, narrow (fig. 26B). Median apophysis retrolateral, long, sinuous. Primary conductor with basal portion hyaline, without canal, not fitted to embolus (fig. 26A); apical portion long, heavily sclerotized, with long canal, connected to basal portion by thin translucent vertical lamina. Secondary conductor triangular, pointed, with ventral membranous area and dorsal patch of denticles (fig. 26C, D). Paramedian apophysis apparently with two cusps, one retrolateral, conical, curved, heavily sclerotized, another ventral, on primary conductor, narrow, small.

VARIABILITY: Male spines: III, tibia v r1ap, p and r d1–1, or 1­ d1­ 1­ 0. IV, tibia v p1­ (p1­ r1)­ 2, r d1–1; metatarsus p 0–1–1.

NATURAL HISTORY: The types were collected by beating the endemic ‘‘colihue’’ bamboos ( Chusquea spp. ).

DISTRIBUTION: Forests in southern Chile, from Cautín to Chiloe´. At the type locality I failed to find them close to sea level.
