Zorocrates terrell , new species figures 73–77 ; map 4

TYPE: Female holotype from 10 miles southeast of Sanderson , Terrell Co. , Texas, deposited in AMNH .

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

Map 4. Records of the Zorocrates mistus group: Z. karli (1), Z. aemulus (2), Z. terrell (3), Z. xilitla (4), Z. potosi (5), Z. apulco (6), Z. sotano (7), Z. tequila (8), Z. mistus (9), Z. pie (10), Z. soledad (11), Z. nochix (12), Z. oaxaca (13), Z. yolo (14). Asterisks indicate uncertain localities.

DIAGNOSIS: Males and females have not been collected together but are tentatively matched here on the basis of geography and their mutual similarity to Z. mistus ; males can easily be recognized by the two prolaterally directed projections on the median apophysis ( fig. 74 ), females by the very wide anterior epigynal margin ( fig. 76 ).
