Figs 178 – 190

Type material. Holotype: male, DOMINICAN REPUBLIC: Pedernales: Peblique , 18.059° N, 71.638° W, elev. 270 m, 17 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, G. Ruiz, N. Corona, WPM#09-041 (UBC-SEM AR00059). Paratypes: 1 female, same data as holotype (UBC-SEM AR00060); 7 males and 10 females in three vials, same data as holotype.

Etymology. A noun in apposition taken from the type locality.

Diagnosis. Similar to Corythalia coronai , but can be distinguished by the markings on the carapace and abdomen (Figs 178 – 179, 183 – 185), the longer male legs (Figs 178 – 181), the curved ridge on the front surface of the male chelicera (Fig. 187), and the wider embolus (Fig. 186).

Description. Male (holotype, UBC-SEM AR00059). Carapace length 2.5 (variation 2.2 – 2.7, n=8); abdomen length 2.4. Chelicera (Figs 187 – 188): dark brown; with one bicuspid promarginal tooth and one retromarginal tooth; anterior surface with a ridge. Palp (Fig. 186): dark brown. Embolus wide with a simple and short curve. Retrolateral tibial apophysis long and finger-like. Tibia of first leg with three pairs of ventral macrosetae and a retrolateral macroseta partially ventral; metatarsus with three pairs of ventral macrosetae. Fringes present on ventral tibiae and patellae of first two pairs of legs, but relatively sparse on leg II. Measurements of legs: I 8.0, II 5.0, III 5.7, IV 5.5. Color in alcohol (Fig. 184): carapace dark brown, without distinct markings; abdomen gray brown scattered with yellow brown speckles, with a light yellow brown band at anterior margin and two yellow brown stripes along the lateral margins of the middle brown patch; venter with two lines of yellow brown speckles; first three pairs of legs dark brown, fourth leg slightly lighter in color with proximal end of femur light yellow.

Figures 184–190. Corythalia peblique sp. nov. 184 male paratype, dorsal view; 185 female paratype, dorsal view; 186 male left palp, ventral view; 187 male left chelicera, front view; 188 male left chelicera, back view; 189 epigynum, ventral view; 190 cleared epigynum, dorsal view. Scale bars: 184 – 185, 1.0 mm; 187 – 188, 0.2 mm; 186, 189 – 190, 0.1 mm.

Female (paratype, UBC-SEM AR00060). Carapace length 2.5 (variation 2.1 – 2.5, n=11); abdomen length 3.0. 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 4.9, II 4.5, III 5.2, IV 5.4. Epigynum (Figs 189 – 190): window occupying more than half of epigynal plate, with opening to copulatory duct close to the anterior margin. Copulatory ducts with accessory gland near the opening; spermathecae oval and located within the window. Color in alcohol (Fig. 185): similar to that of the male but legs yellow brown.

Natural history. Specimens were found on leaf litter or on rocks in a relatively dry forest. This species seems to become active in the late afternoon. Several hours of collecting in the forest yielded many salticids, including many from leaf litter and rocks, but none (or very few) of this species until approximately 6:00 pm, when over the span of about 15 minutes they became commonly seen.
