Zorocrates chamula View in CoL , new species figures 63–67 View Figs ; map 3

TYPE: Female holotype from an elevation of 2530 m at Laguna Chamula , microwave tower between Comitán and Amatenango del Valle, Chiapas, Mexico (Aug. 20, 1972; C. Mullinex, K. Lucas), deposited in CAS .

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

DIAGNOSIS: Males and females have not been collected together and are only tentatively matched here; males can easily be recognized by the pick-shaped median apophysis ( fig. 64 View Figs ), females by the large anterior epigynal protuberance ( fig. 66 View Figs ).

MALE: Total length 13. Coloration as in Z. chiapa . Leg spination: femora: I p0-0-2, r1-1-2; II p1-1-1, r3-2-2; III p1-1-2, r1-1-2; IV p1-1-1, r0-0-1; patellae IV r0-1-0; tibiae: I d0-0-0, r1-0- 1; II d0-0-0, p1-1-1, v4-2-2, r1-0-1; III r1-0-1; IV d1-1-1; metatarsi: I p0-1-1, v2-2-2, r0-1-0; II p0-1-1; IV r0-2-2. Cribellum present. Retrolateral tibial apophysis small, sharply pointed; median apophysis pick-shaped, with two long and one shorter projection; tegular apophysis distally bifid ( figs. 63–65 View Figs ).

FEMALE: Total length 13. Coloration as in male except abdominal dorsum with median longitudinal stripe reduced to rows of paired pale spots. Leg spination: femora: I d1-1-0, p0-0-2, r0-0-0; II d1-1-0, p0-1-1, r1-1-0; III p0- 1-1, r0-1-1; IV d1-1-0, p0-0-1, r0-0-1; patellae III, IV p0-0-0, r0-0-0; tibiae: I d0-0-0, p0-0-0, v2-4-2, r0-0-0; II d0-0-0, p0-0-1, v2-4-2, r0-0-0; III d1-1-0, r1-0-1; IV d1-0-0; metatarsi: I p0-0- 1, v2-2-2, r0-0-0; II p1-0-1, v2-2-2, r0-0-1; III r1-1-2; IV v3-2-2. Cribellum present. Anterior epigynal margin prolonged as posteriorly expanded projection; spermathecae ovoid ( figs. 66, 67 View Figs ).

OTHER MATERIAL EXAMINED: MEXICO: Chiapas: Comitán, Sept. 9, 1960 (UNAM), 13; Cruz Quemada , near Amatenango, July 24, 1950 m (C., M. Goodnight, AMNH), 13; Lagos de Montebello , Sept. 4, 1972 (C. Mullinex, K. Lucas, CAS), 13; Laguna Chamula , microwave tower between Comitán and Amatenango del Valle, Aug. 20, 1972, elev. 2530 m (C. Mullinex, K. Lucas, CAS), 1♀ ; 17 km SE San Cristóbal de las Casas , Sept. 2, 1972, elev. 2164 m (C. Mullinex, CAS), 8♀ .

DISTRIBUTION: Known only from Chiapas, Mexico (map 3).

THE MISTUS GROUP

The remaining species seem to represent a single group. All the known males share a flattened and platelike median apophysis, often bizarrely modified in various ways. The females have pronounced posterior epigynal margins.

Zorocrates mistus View in CoL O. P.- Cambridge, 1896: 176, pl. 21, figs. 9, 9a–g, 10, 10a View Figs (one female and two male syntypes from Omiltemi, Guerrero, Mexico, in BMNH, examined). – F. O. P.- Cambridge, 1902: 354, pl. 33, figs. 10, 10a View Figs , 11. View Figs

DIAGNOSIS: Males can easily be recognized by the huge, recurved median apophysis with a pronounced, prolaterally directed extension ( fig. 69 View Figs ), females by the relatively narrow anterior epigynal margin, posteriorly expand- ed epigynal midpiece, and wide posterior epigynal margins ( fig. 71 View Figs ).

MALE: Total length 8. Coloration as in Z. fuscus . Leg spination: femora: I p0-0-2, r1-1-1; II p0-1-1, r1-1-2; III p0-2-1; IV p0-1-2, r0-0-2; patellae IV r0-1-0; tibiae: I d0-0-0, p0-0-1, v4- 2-2, r0-0-0; II d0-0-0, p0-1-1, v4-2-2, r0-0-0; III r1-0-1; metatarsi: I p0-0-0, v2-2-2, r0-0-0; II p0-0-1, r0-0-0; III r1-2-2; IV p1-2-2. Cribellum possibly reduced but present. Retrolateral tibial apophysis relatively wide, prolaterally

incised near tip; median apophysis occupying over half of bulbal length and width, with prolaterally directed extension; tegular apophysis tall retrolaterally, short prolaterally ( figs. 68–70 View Figs ).

FEMALE: Total length 9. Coloration as in male. Leg spination mostly unknown (most legs detached, mixed with those of one male syntype), only right leg I still attached, with femur d1-1-0, p0-0-2, tibia d0-0-0, p0-0-0, v4- 2-2, r0-0-0, metatarsus p0-0-0, v2-2-2, r0-0-0. Cribellum present. Anterior epigynal margin relatively narrow, recurved, midpiece expand- ed prolaterally, posterior margins protuberant; spermathecae with anteriorly directed lateral ducts ( figs. 71, 72 View Figs ).

MATERIAL EXAMINED: MEXICO: Guerrero: Omiltemi , elev. 7000–9000 ft (H. Smith, BMNH 1895.4.28.1341–1346), 23, 1♀ (syntypes) .

DISTRIBUTION: Known only from Guerrero, Mexico (map 4).
