Zorocrates fuscus : Simon, 1892: 230 (emendation of gender). Zorocrates cf. guerrerensis : Silva, 2003: 41 , fig. 13a. NOTE: In the original description, the type locality is presented only as ‘‘Mexique’’ but Simon later (1895b: 106) specified ‘‘Mexique central’’ and that later restriction corroborates the current label with the syntypes , which indicates that the specimens were collected in Guanajuato , Mexico , by Dugès . DIAGNOSIS: Males resembles those of Z. unicolor but have a longer, fingerlike (rather than ledge-shaped) proximal lobe on the retrolateral tibial apophysis, a distally rounded median apophysis ( figs. 2, 3 ), and a ventrally shorter tegular apophysis; the median apophysis does have a small, subdistal denticle, but it is directed dorsally and is therefore easy to overlook in ventral view (the denticle is more prolaterally directed and conspicuous in males of Z. unicolor ). Females also resemble those of Z. unicolor but have deeper epigynal pockets with smaller, more medially situated openings connected to anteriorly expanded margins that parallel a longitudinal ridge between the pocket and the epigynal midpiece ( fig. 4 ). Figs. 1–5. Zorocrates fuscus Simon. 1. Left male palp, prolateral view. 2. Same, ventral view. 3. Same, retrolateral view. 4. Epigynum, ventral view. 5. Same, dorsal view. MALE: Total length 14. Carapace light brown with dusky triangular markings radiating from thoracic groove; abdomen gray, with lighter cardiac spot, posterior one-fifth with chevron pattern; femora light brown, more distal leg segments grading to brown on metatarsi and tarsi. Leg spination: femora: I r1-1-2; II p0-1-2, r1-1-2; III p1-1-1; IV r0-0-2; patellae IV r0-1-0; tibiae III r1-0-1; metatarsi I p1-1-1, v2-2-0, r1-1-0. Cribellum present. Retrolateral tibial apophysis short, with fingerlike proximal lobe; median apophysis hook-shaped, distally rounded; tegular apophysis sharply pointed ( figs. 1–3 ). Map 1. Records of the Zorocrates fuscus group (excluding Z. unicolor ): Z. fuscus (dots), Z. guerrerensis (triangles; suspect record from Panama not plotted), Z. gnaphosoides (circles), Z. ocampo (open squares), Z. mordax (filled square). FEMALE: Total length 16. Coloration as in male. Leg spination: femora: I, II p0-1-1, r1-1-0; IV p2-0-1, r0-0-1; patellae IV p0-0-0, r0-1-0; tibiae: I, II d0-0-0, p0-0-0, r0-0-0; III r1-0-1; IV r2-0-1; metatarsi: I p0-0-0, r0-0-0; II p0-0-0, r0- 0-1; III p1-1-2, r1-1-2; IV v3-2-2. Cribellum present. Epigynal midpiece triangular, with transverse anterior ledge; lateral pockets present, with relatively small openings; spermathecae with short anterior lobes ( figs. 4, 5 ).
