Type material. Holotype: male, DOMINICAN REPUBLIC: Pedernales: Laguna de Oviedo , 17.802° N, 71.349° W, elev. 5 m, 18 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, G. Ruiz, N. Corona, WPM#09-045 (UBC- SEM AR00051). Paratypes: 1 female, same data as holotype (UBC-SEM AR00052); 2 females in two vials, same data as holotype; 1 female, DOMINICAN REPUBLIC: Pedernales: Laguna de Oviedo , 17.802° N, 71.349° W, elev. 5 m, 14 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, G. Ruiz, WPM#09-032; 2 females, same data as previous.

Etymology. Latin adjective latus (wide), referring to the wide first pair of legs in male.

Diagnosis. Differs from Corticattus guajataca by the widened first pair of legs in male (Figs 126 – 129, 132), the thinner embolus (Fig. 134), the longer copulatory ducts (Fig. 138), the smaller epigynal window and the more laterally located opening to the copulatory duct (Fig. 137).

Figures 132–138. Corticattus latus sp. nov. 132 male holotype, dorsal view; 133 female paratype, dorsal view; 134 male left palp, ventral view; 135 male left palp, retrolateral view; 136 female right chelicera, back view; 137 epigynum, ventral view; 138 cleared epigynum, dorsal view. Scale bars: 132 – 133, 0.5 mm; 134 – 138, 0.1 mm.

Description. Male (holotype, UBC-SEM AR00051). Carapace length 1.3; abdomen length 1.4. Fovea far behind PLEs. Chelicera: red brown. Palp (Figs 134 – 135): gray brown to yellow brown. Embolus relatively thin. Retrolateral tibial apophysis long and finger-like; ventral tibial bump distinct. First pair of legs robust, with no macrosetae on tibia and metatarsus. Measurements of legs: I 1.7, II 1.6, III 1.8, IV 1.9. Color in alcohol (Fig. 132): carapace eye area dark brown, remainder yellowish brown; dorsal area of carapace covered with white setae; abdomen light gray brown, with a medial gray brown stripe; venter gray brown; first pair of legs yellowish brown to dark yellowish brown, other legs light yellow with gray annuli.

Female (paratype, UBC-SEM AR00052). Carapace length 1.3 (variation 1.2 – 1.3, n=6); abdomen length 1.6. Tibia of first leg with three ventral macrosetae; first metatarsus with two pairs of macrosetae. Measurements of legs: I 1.6, II 1.5, III 2.0, IV 2.1. Epigynum (Figs 137 – 138): window with very narrow median septum; opening to copulatory duct almost at its center. Copulatory ducts long, with large accessory gland; spermathecae spherical. Color in alcohol (Fig. 133): similar to that of male except first pair of legs lighter in color.

Natural history. Specimens were found on or under bark or by beating branches in dry forest.
