Corythalia coronai sp. nov.

Figs 165 – 177

Type material. Holotype: male, DOMINICAN REPUBLIC: Pedernales: Rio Mulito, 18.155° N, 71.758° W, elev. 270 m, 16 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, G. Ruiz, N. Corona, WPM#09-036 (UBC-SEM AR00057). Paratypes: 1 female, same data as holotype (UBC-SEM AR00058); 13 males and 8 females in three vials, same data as holotype.

Etymology. The specific epithet is a patronym in honor of Mr. Nicolas Corona, who helped in collecting specimens during the expedition to the Dominican Republic in 2009.

Diagnosis. Unlike Corythalia broccai and C. bromelicola , the carapace is not swollen behind the ALEs (Fig. 171), and the copulatory duct openings are more anterior (Figs 176 – 177). It can be distinguished from Wallaba decora Bryant, 1943 by the shorter embolus and the narrower retrolateral sperm duct loop of the male palp (Fig. 173), and the more widely spread iridescent scales on the male carapace (Fig. 165). See also the diagnosis of C. peblique for differences with that species.

Figures 171–177. Corythalia coronai sp. nov. 171 male paratype, dorsal view; 172 female paratype, dorsal view; 173 male left palp, ventral view; 174 male left chelicera, front view; 175 male left chelicera, back view; 176 epigynum, ventral view; 177 cleared epigynum, dorsal view. Scale bars: 171 – 172, 1.0 mm; 174 – 175, 0.2 mm; 173, 176 – 177, 0.1 mm.

Description. Male (holotype, UBC-SEM AR00057). Carapace length 2.0 (variation 1.5 – 2.1, n=14); abdomen length 1.8. Chelicera (Figs 174 – 175): dark brown; with one bicuspid promarginal tooth and one retromarginal tooth; front surface with a straight ridge. Palp (Fig. 173): tarsus brown, other segments light yellow. Embolus short and slightly curved; retrolateral sperm duct loop less than half of bulb width. Retrolateral tibial apophysis long and finger-like. Tibia and metatarsus of first leg with three pairs of ventral macrosetae each. First two pairs of legs with dorsal and ventral fringes. Measurements of legs: I 4.2, II 3.5, III 4.1, IV 4.4. Color in alcohol (Fig. 171): carapace dark brown, with markings behind PLEs composed of iridescent scales; abdomen dark brown with a medial brown stripe; venter with two lines of yellow brown small spots behind genital groove; first two pairs of legs dark brown and last two pairs of legs yellow brown.

Female (paratype, UBC-SEM AR00058). Carapace length 1.9 (variation 1.9 – 2.1, n=9); abdomen length 2.5. 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 3.3, II 3.1, III 3.8, IV 4.2. Epigynum (Figs 176 – 177): window occupying about two thirds of epigynal plate, with opening to copulatory duct close to the margin. Copulatory ducts with accessory gland near the opening; spermathecae oval and located within the window. Color in alcohol (Fig. 172): similar to that of the male but legs brown.

Natural history. Specimens were found on leaf litter in broad-leaf forest.
