Type material. Holotype: male, DOMINICAN REPUBLIC: El Seibo: Pedro Sanchez - Miches Road, 18.958° N, 69.069° W, elev. 157 m, 22 July 2009, coll. W. Maddison, G. Ruiz, J. Brocca, WPM#09-053 (UBC-SEM AR00053). Paratypes: 1 female, same data as holotype (UBC-SEM AR00054); 4 females and 1 male in three vials, same data as holotype.
Etymology. The specific epithet is a patronym in honor of Mr. J. Brocca, who provided great help in organizing the field work in the Dominican Republic in 2009 during which this species was discovered.
Diagnosis. Can be distinguished from Dinattus minor Bryant, 1943 by the absence of distinct lateral extensions on the male carapace (Fig. 148) and the detailed structure of the male palp (Fig. 147). Also, see the diagnosis of Corythalia bromelicola.
Description. Male (holotype, UBC-SEM AR00053). Carapace length 1.8; abdomen length 1.6. Chelicera (Fig. 149): red brown; with one bicuspid promarginal tooth and one retromarginal tooth. Palp (Fig. 147): dark brown. Embolus short and slightly curved; retrolateral sperm duct loop reduced. Retrolateral tibial apophysis long and finger-like. Tibia and metatarsus of first leg with three pairs of ventral macrosetae each. First pair of legs with dorsal fringe on femur and ventral fringes on femur, patella and tibia; second pair of legs with ventral fringe on femur. Measurements of legs: I 3.9, II 3.2, III 3.8, IV 3.8. Color in alcohol (Fig. 145): carapace dark brown, with narrow lateral margins and markings around posterior eyes and behind fovea composed of iridescent scales; abdomen brown with light yellow brown markings; first two pairs of legs dark brown, last two pairs of legs yellow brown with dark brown markings.
Female (paratype, UBC-SEM AR00054). Carapace length 2.0 (variation 1.7 – 2.0, n=5); abdomen length 2.2. Chelicera: with one bicuspid promarginal and one retromarginal tooth. First leg with three pairs of ventral macrosetae on tibia and metatarsus each. Measurements of legs: I 3.9, II 3.5, III 4.3, IV 4.2. Epigynum (Figs 150 – 151): window occupying about half of epigynal plate, with opening to copulatory duct at its posterior margin. Spermathecae oval, located within the window. Color in alcohol (Fig. 146): similar to that of the male except legs lighter in color.
Natural history. Specimens were collected on leaf litter in a disturbed forest with planted cacao trees.
