Zorocrates soledad , new species figures 93–97 ; map 4

TYPE: Female holotype from Soledad Atzompa , Veracruz, Mexico (Jan. 5–6, 1974; J. Reddell, X. Lopez), deposited in AMNH .

90. Same, retrolateral view. 91. Epigynum, ventral view. 92. Same, dorsal view.

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 respective similarities to Z. apulco ; males can easily be recognized by blade-shaped retrolateral tibial apophysis ( fig. 95 ) and distally widened medi- an apophysis ( fig. 94 ), females by the wide epigynal midpiece subtended by w-shaped posterior epigynal margins ( fig. 96 ) and the loosely coiled spermathecal ducts ( fig. 97 ).

MALE: Total length 10. Coloration as in Z. blas . Leg spination: femora: I d1-1-0, p0-0-2, r0-0-0; II d1-1-0, p0-0-1, r0-0-0; III p1-1-1, r0- 0-1; IV d1-1-0, p0-1-0, r0-0-1; patellae III p0- 0-0; IV r0-1-0; tibiae: I d0-0-0, p0-0-0, r0-0-0; II d0-0-0, p0-1-1, v3-2-2, r0-0-0; III r1-0-1; metatarsi: I, II p0-0-1, v2-2-2, r0-0-0. Cribellum present. Retrolateral tibial apoph-

ysis flattened, blade-shaped; median apophysis greatly widened, with prolateral hook; tegular apophysis trifid ( figs. 93–95 ).

FEMALE: Total length 11. Coloration as in male. Leg spination: femora: I d1-1-0, p0-0-2, r0-0-0; II d1-1-0, p0-1-1, r0-0-0; III p0-1-2, r1- 1-2; IV p2-0-1, r0-0-1; patellae IV r0-1-0; tibiae: I, II d0-0-0, p0-0-0, r0-0-0; III r1-0-1; IV r1-1-1; metatarsi: I, II p0-0-0, v2-2-2, r0-0- 0; III r1-2-2. Cribellum present. Anterior epigynal margin angular; midpiece abruptly narrowed anteriorly; posterior margins forming w-shaped figure; spermathecal ducts loosely coiled ( figs. 96, 97 ).

Zorocrates karli Gertsch and Riechert, 1976: 9 , figs. 5 , 6 (male holotype from Lincon Co., New Mexico, in AMNH, examined).

DIAGNOSIS: Males and females have not been taken together but are tentatively matched here on the basis of geography, coloration, and their respective similarities to other members of the mistus group. Males can easily be recognized by their long, narrow median apophysis ( figs. 98–100 ), females by the arched anterior epigynal margin ( fig. 101 ).

MALE: Total length 11. Coloration as in Z. fuscus except abdominal dorsum mostly pale white, with paramedian darker markings. Leg spination: femora: I p0-0-2, r0-1-0; II p0-1-1, r0-1-0; IV p2-0-2, r0-0-2; patellae IV p0-0-0; tibiae: I d0-0-0, p0-0-0, r0-0-1; II d0-0-0, p1-0- 0, r0-1-0; III d0-1-1, r1-0-1; IV d1-1-1; metatarsi: I p0-0-0, v2-2-2, r0-1-0; II p0-1-0, r0-1-0; III r1-2-2. Cribellum present. Retrolateral tibial apophysis directed anteriorly, expanded at tip; median apophysis greatly elongated, sinuous, expanded at tip; tegular apophysis greatly widened ( figs. 98– 100 ).

FEMALE: Total length 10. 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 p0-1-2, r0- 1-2; IV d1-1-0, p0-0-1, r0-0-1; patellae IV r0-1- 0; tibiae: I, II d0-0-0, p0-0-0, r0-0-0; III r1-0-1; IV d1-1-1; metatarsi: I, II p0-0-0, v2-2-2, r0-0- 0; III r1-2-2; IV v3-2-2. Cribellum present. Anterior epigynal margin arched, midpiece only slightly widened posteriorly; lateral epigynal ducts relatively small ( figs. 101, 102 ).
