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

Diagnosis. A. bahoruco can be distinguished from other Agobardus by the flattened body (Figs 1 – 4). Similar in epigynum (Fig. 9) to Agobardus phylladiphilus , but differs by abdominal markings (Figs 5 – 6), the modified male chelicera (Fig. 8) and the longer tibia of the male palp (Fig. 7). The flattened body is similar to Antillattus applanatus and Commoris modesta Bryant, 1943 . It can be distinguished from Antillattus applanatus by the bicuspid retromarginal tooth on the female chelicera (one unident tooth in Antillattus applanatus ), the male cheliceral shape (Fig. 8), the absence of a proximal tegular lobe and the wide retrolateral sperm duct loop of the male palp (Fig. 7). It differs from Commoris modesta Bryant, 1943 in the shorter embolus and the longer tibia of the male palp (Fig. 7).

Description. Male (holotype, UBC-SEM AR00030). Carapace length 2.2; abdomen length 2.4. Body dorsalventrally slightly flattened. Chelicera (Fig. 8): dark brown; with two promarginal teeth and one retromarginal tooth of six cusps; retromargin also with a blunt spur between the retromarginal tooth and the base of fang; fang with a small cusp near the middle. Palp (Fig. 7): yellow brown. Embolus relatively short and curved. Retrolateral tibial apophysis finger-like. Palpal femur and patella dorsally with white hairs. Measurements of legs: I 4.9, II 4.0, III 4.4, IV 4.7. Color in alcohol (Fig. 5): carapace dark brown, but lateral margins covered with white setae; abdomen gray brown with a light brownish yellow marking and some small light colored speckles; venter gray brown with two light brownish yellow longitudinal stripes; legs gray brown with light yellow markings.

Female (paratype, UBC-SEM AR00031). Carapace length 2.3 (variation 1.8 – 2.3, n=3); abdomen length 2.8. Measurements of legs: I 4.1, II 3.9, III 4.5, IV 5.0. Epigynum (Figs 9 – 10): window occupying less than half of the epigynal plate, with relatively wide median septum; opening of copulatory duct at the posterior margin of the window. Copulatory ducts short and with accessory gland; spermathecae pear-shaped. Color in alcohol (Fig. 6): similar to that of the male.

Natural history. Specimens were found on pine tree trunks in a forest.
