Type material. Holotype: male, DOMINICAN REPUBLIC: La Vega: road Constanza to Ocoa, Valle Nuevo, 18.829° N, 70.691° W, elev. 2070 m, 12 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, G. Ruiz, WPM#09-023 (UBC-SEM AR00047). Paratypes: 1 female, same data as holotype (UBC-SEM AR00048); 1 female, same data as holotype.

Etymology. Latin adjective applanatus (flattened), referring to the flattened body of the species.

Diagnosis. Distinguished from other known Antillatus by the flattened body (Figs 90, 92), the less elongated male chelicera (Fig. 98), the absence of a spur on the front surface of the male chelicera (Fig. 98), the unident retromarginal tooth (Fig. 98) and the vulva shape (Fig. 100). Also, see the diagnosis of Agobardus bahoruco .

Description. Male (holotype, UBC-SEM AR00047). Body relatively flattened. Carapace length 2.7; abdomen length 2.8. Chelicera (Fig. 98): brown; internal margin concave and with two small processes; promargin with two teeth and retromargin with one tooth. Palp (Fig. 96): tibia and tarsus yellow brown, other segments light yellow. Embolus short, retrolateral sperm duct loop narrow. Retrolateral tibial apophysis finger-like. Tibia of first leg with three pairs of ventral macrosetae and metatarsus with two pairs. Measurements of legs: I 6.6, II 5.1, III 5.7, IV 6.1. Color in alcohol (Fig. 94): carapace gray brown, paler around fovea, lateral margins white; abdomen light yellow brown, with a pair of elongated gray brown medial markings and paired white spots at posterior part, venter with gray patches; first pair of legs brown to light brown, other legs light yellow with brown annuli.

Figures 94–100. Antillatus applanatus sp. nov. 94 male holotype, dorsal view; 95 female paratype, dorsal view; 96 male left palp, ventral view; 97 male endites and labium, ventral view; 98 male left chelicera, back view; 99 epigynum, ventral view; 100 cleared epigynum, dorsal view. Scale bars: 94, 2.0 mm; 95, 1.0 mm; 97 – 98, 0.2 mm; 96, 99 – 100, 0.1 mm.

Female (paratype, UBC-SEM AR00048). Carapace length 2.5 (variation 2.1 – 2.5, n=2); abdomen length 3.5. Chelicera: with two promarginal teeth and one retromarginal tooth. First leg with three pairs of ventral macrosetae on tibia and two pairs on metatarsus. Measurements of legs: I 4.5, II 4.2, III 5.1, IV 5.5. Epigynum (Figs 99 – 100): window relatively small, with opening to copulatory duct at its posterior margin. Copulatory ducts short, without accessory gland; secondary spermathecae not obvious, primary spermathecae oval. Color in alcohol (Fig. 95): similar to that of the male.

Natural history. Specimens were collected on pine tree trunks in forest.
