Holotype. Male ( Fig. 1). Body oval. Length 8.99 mm, width 5.19 mm. Head and pronotum dark brown. Scutellum reddish brown. Elytra dark brown but lighter than pronotum. Pygidium ochre. Legs orange on femur, reddish brown on tibia and tarsus. Venter orange on sternum, abdominal sternites ochre. Head: Clypeus trapezoidal, short, surface densely punctate-reticulate, convex; anterior margin curved, clypeus thick in frontal view; width/length ratio 2.50. Frons sparsely punctate, flat. Ocular canthus long, thin, with rounded apex. Ratio of interocular width/width of eye 2.84. Ratio antennal funiculus/club 0.74. Pronotum: Subtrapezoidal. Ratio width/length 1.69. Lateral margins angulated at 1/3 of pronotal length from the anterior margins. Anterior angles acute, posterior angles obtuse. Basal margin sinuate, subapical bead obliterated at middle. Surface with deep, dense punctures. Scutellum: Subtriangular, with rounded sides, and acute apex. Ratio width/length 1.19. Surface sparsely punctate. Elytra: With costae defined by regular rows of punctures. Subsutural interstice with 1–2 rows of sparse punctures, 2 nd –4 th interstices with 1 irregular, secondary stria. Pygidium: Sparsely punctate with long setae on posterior margin. Ratio width/length 1.77. Venter: Space between mesocoxae narrow, flat. Mesometasternal suture well-defined at base of mesocoxae. Abdominal sternites with 1 row of setae and 4–5 rows of punctures per sternite. Last sternite strigate, with subapical bead thin and sinuate, apical membrane thin. Legs: Protibia ( Fig. 9) tridentate, apical tooth long and curved, middle tooth above internal apex of protibia, triangular in shape, acute, basal tooth sharp. Metatibia stout, fusiform; ratio length/width 2.81. First external carina with row of sparse setae, surface punctate. External protarsal claw strongly curved, internal claw bifurcate, with upper branch slightly shorter and 2/3 width of the lower one, inferior margin curved. Male genitalia: Parameres slender ( Fig. 17), with squared, protruding apex in lateral view, ventral margin sinuate. Endophallus ( Fig. 25) with 1 long, glabrous sacculus. Ejaculatory duct opening frontally on a ventral inflation.

Female. Similar to male except protibia ( Fig. 9) with wider teeth; last sternite with curved apex.

Variation. Six paratypes. Dorsal surface varies from dark reddish brown to dark brown; pygidium and venter from orange to ochre. Body length 8.99–10.17 mm, body width 5.19–5.76 mm. Clypeal width/length ratio 2.50–2.93. Ratio of interocular

6) A. robiginosa   ; 7) A. strigodermoides   ; 8) A. unilineata   . Scale bar = 5 mm.

width/width of eye 2.84–3.19. Ratio of antennal funiculus/club 0.73–0.79. Pronotal width/length ratio 1.69–1.72. Scutellar width/length ratio 1.13–1.33. Pygidial width/length ratio 1.68–1.82. Metatibial length/width ratio 2.60–2.81.

Etymology. From the generic name of coffee plants, to be treated as a noun in apposition, for its resemblance in shape and color to toasted coffee beans, a famous Costa Rican product.

Distribution. This species is found in the humid forest on the northwest side of the Guanacaste mountain range, Costa Rica, at 700 m elevation ( Fig. 34).

Diagnosis. This species is recognized by its small size, color homogeneously dark brown, elytra with defined costae and interstices with rows of punctures, and tridentate protibia. The small size and brown color is similar to that of species of Anomala   in the subgenus Bucaphallanus Ramírez-Ponce and Morón, 2012   , but A. coffea   does not share any diagnostic character with any of its species and has more defined punctation on the elytra.
