Zorocrates bosencheve , new species figures 43–47 ; map 3

TYPE: Female holotype from Parque Nacional Bosencheve , Michoacán, Mexico (Sept. 4, 1966; J., W. Ivie), deposited in AMNH .

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

DIAGNOSIS: Males and females have not been collected together, but are tentatively matched here on the basis of their mutual similarities to the other members of this species group. Males can easily be recognized by the short, thumb-shaped retrolateral tibial apophysis and the elongated tip of the median apophysis ( figs. 44, 45 ), females by the posteriorly widened median epigynal septum ( fig. 46 ).

MALE: Total length 9. Coloration as in Z. badius . Leg spination: femora: I, II p0-1-2, r1- 1-2; III r0-1-2; IV r0-0-1; patellae IV r0-1-0; tibiae: I d0-0-0, p1-1-1, v2-4-2, r0-1-1; II d0-0- 0, p1-0-1, v2-4-2, r0-1-1; III r1-0-1; IV r1-1-1; metatarsi: I p0-1-0, v2-2-2, r0-0-0; II p1-0-1, r0-1-1; III r1-2-2; IV p1-2-2. Cribellum present. Retrolateral tibial apophysis short, thick, thumb-shaped; median apophysis elongated, with greatly elongated tip; tegular apophysis with sinuous prolateral margin ( figs. 43–45 ).

FEMALE: Total length 9. Coloration as in male. Leg spination: femora: I d1-1-0, p0-0-2, r0-0-0; II d1-1-0, p0-0-1, r0-0-0; III p0-1-1, r0- 1-1; IV p0-0-1, r0-0-1; patellae IV r0-1-0; tibiae: I d0-0-0, p0-0-0, r0-0-0; II d0-0-0, p0- 1-0, v4-2-2, r0-0-0; III r1-0-1; IV d1-1-1, r2-0- 1; metatarsi: I p0-0-0, v2-2-2, r0-0-0; II p0-0-1, r0-0-0; III r1-2-2. Cribellum present. Median epigynal septum wider posteriorly than anteriorly, lateral margins extending about half its length; spermathecal ducts anteriorly transverse ( figs. 46, 47 ).

OTHER MATERIAL EXAMINED: MEXICO: Colima: Nevado de Colima, Jan. 20, 1943 (F. Bonet, AMNH), 13. Michoacán (?): ‘‘ 3 mi. west of Guerrero line’’, July 14 (AMNH), 1♀. Morelos: Zempoala, May 31, 1942, elev. 2800 m (C. Bolivar, AMNH), 1♀.
