Zorocrates xilitla View in CoL , new species figures 78–82 View Figs ; map 4

TYPE: Female holotype taken in a flight intercept trap at an elevation of 1700 m in a pine-oak forest 40 km west of Xilitla , San Luis Potosı´, Mexico (June 12–Aug. 6, 1983; S., J. Peck), deposited in AMNH .

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

DIAGNOSIS: The lack of a cribellum separates this species from all others except Z. potosi , from which it can be distinguished by the larger median apophysis of males ( fig. 79 View Figs ) and the anteriorly narrower epigynum of females ( fig. 81 View Figs ).

MALE: Total length 9. Coloration as in Z. fuscus . Leg spination: femora: I p0-0-2, r0-1-1; II p0-1-1, r1-1-1; III r1-1-1; IV p1-1-1, r0-0-1; patellae IV r0-1-0; tibiae: I, II d0-0-0, p0-1-1, v4-4-2, r0-1-0; III r1-0-1; metatarsi: I p0-0-0, v2-2-2, r0-0-0; II p0-0-0, r0-1-0; III r1-2-2. Cribellum absent, represented only by small, fleshy, setose colulus. Retrolateral tibial apophysis strong, straight; median apophysis greatly expanded distally, with prolaterally directed, sharp projection; tegular apophysis short, with distinct prolateral prong ( figs. 78– 80 View Figs ).

FEMALE: Total length 10. Coloration as in male. Leg spination: femora: I d1-1-0, p0-0-2, r0-0-0; II p0-0-1, r0-0-0; III p0-2-2, r1-1-1; IV p2-0-1, r0-0-1; patellae IV r0-1-0; tibiae: I, II d0-0-0, p0-0-0, v4-4-2, r0-0-0; III r1-0-1; IV d1-0-1; metatarsi: I, II p0-0-0, v2-2-2, r0-0-0; III r1-2-2. Cribellum absent, represented only by small, fleshy, setose colulus. Epigynum with wide, rectangular posterolateral sclerotizations, lateral margins of midpiece excavated; spermathecae with anteriorly directed lateral ducts ( figs. 81, 82 View Figs ).

OTHER MATERIAL EXAMINED: Four males taken with the holotype (AMNH).

DISTRIBUTION: Known only from San Luis Potosı´, Mexico (map 4).
