Holotype male description. Body shape elongate. Length 16.8 mm. Width 8.6 mm.
Color. Head, pronotum, scutellum, pygidium, legs, and venter black. Elytra ochre with irregular black maculae: 3 pairs along basal margin, 1 median, 1 on sides towards apex; the latter with small flecks near edges.
Clypeus trapezoidal, surface densely punctate-reticulate, flat. Anterior margin straight, clypeus anteriorly thin. Clypeus ratio width/length 2.2. Frons densely punctate, flat. Ocular canthum long, narrow, with rounded apex. Interocular ratio (interocular width/width of eye): 2.7. Antenna: ratio funiculus/club 0.7.
Pronotum subtrapezoidal. Ratio width/length 1.8. Lateral margins regularly convex. Anterior angles right, blunt; posterior angles obtuse, blunt. Basal margin sinuate, subapical bead complete. Surface densely punctate.
Scutellum. Shape subpentagonal, with rounded sides and acute apex. Ratio width/length 1.3. Surface sparsely punctate.
Elytra with costae defined by regular rows of punctures. Subsutural interstice with 2–3 rows of punctures, 2nd– 4th interstices with 1–2 irregular secondary striae.
Pygidium finely strigate, with long setae at apical margin. Ratio width/length 1.8.
Space between the mesocoxae narrow, slightly convex. Mesometasternal suture well defined, at base of mesocoxae. Abdominal sternites with 1 row of setae (2–3 rows on 2nd sternite) and 3–5 rows of punctures per sternite. Terminal sternite strigate, with subapical bead thick and sinuate, apical membrane wide.
Protibia (Fig. 9) bidentate; apical tooth long and curved; basal tooth at the same level as internal apex of protibia, triangular in shape, sharp, acute. Metatibia stout, fusiform. Ratio length/width 3.1. First external carina constituted by a row of sparse setae, surface punctate above second external carina, and rugose below. Protarsal claws: internal claw bifurcate, with upper branch of same length and 2/3 the width of the lower branch, inferior margin sinuate.
Aedeagus (Fig. 15): parameres stout; with protruding, narrow apex ending sharply. Ventral angle nearly quadrate, blunt. Endophallus (Fig. 21) with 1 long sacculus with a small patch of sclerotized spines near apex; ejaculatory duct opening ventrally at base; median lobes heavily sclerotized.
Variation. Extension of dark maculae on elytra variable. Female similar to male, protibia (Fig. 9) with longer and wider apical tooth; basal tooth above internal apex; internal protarsal claw narrower with curved inferior margin; terminal sternite with curved apex.
Body length 15.7–17.6 mm, body width 8.6–9.3 mm. Clypeus w/l: 2.00–2.2. Interocular ratio (interocular width/width of eye): 2.5–2.7. Antenna: ratio funiculus/club 0.7–0.8. Pronotum w/l: 1.7–1.8. Scutellum w/l: 1.2– 1.6. Pygidium w/l: 1.7–1.9. Metatibia l/w: 2.8–3.1.
Diagnosis. Large size; black pronotum and irregular maculae on elytra; parameres stout, with protruding narrow, acute apex.
The most similar species are A. inconstans and A. pincelada, but they are smaller, have ochre margins on pronotum, have a different pattern of maculae on elytra, and have different shaped aedeagus: A. pincelada has a bifurcate apex of parameres (Fig. 16), A. inconstans has parameres with a frontal lobe-like expansion on anterior part of ventral margin (Fig. 33).
Etymology. This species is dedicated to INBio, Instituto Nacional de Biodiversidad in Costa Rica, for its efforts in increasing the knowledge of Costa Rican biodiversity. This name should be treated as a noun in apposition.
Distribution: Caribbean lowlands, from 0–167 m (Fig. 35).
