HOLOTYPE: Female. Costa Rica: Prov. Cartago, Turrialba , CATIE, 30­VI–1­VII­1996, beating foliage and flowering trees, J. Rifkind, H. Lezama ( LACM). (Specimen pin mounted, sex label affixed to support card; white, machine printed; locality label, white, bordered in black, machine printed; AMNH repository label, white, machine printed; holotype label, red, machine printed.)

PARATYPES: Seven specimens. Costa Rica: Cartago: Cartago, 11­VI­1987, on Croton, F. Hovore ( WFBC, 1; WOPC, 1) ; CATIE, 3 km SE Turrilba , 600 m, 14­V­1985, J. Chemsak ( WOPC, 1): San Jose: Estac. Bijagual, I­ 1990, R. Zuniga ( INBC, 1): Limon: Est. Hitoy Cerere, R. Cerere, Res. Biologica Hitoy Cerere, 100 m, Malaise, 1992 ( INBC, 1; WOPC, 1): Heredia: 10 km W Puerto Viejo, 170 m, 1­III­1991, H. & A. Howden ( CMNC, 1) .

DIAGNOSIS: Distinguishable from the superficially similar specimens of A. chondrus , n.sp., by the expansion of the elytra at the middle, and from A. sabulous , n.sp., by the more convex condition of the pronotal side margins.

DESCRIPTION: Size: Length 4.0–6.0 mm; width 1.7–2.5 mm. Integument: Black. Vestiture: Integument densely vested with prominent light and dark setae; elytral middiscal setal tuft comprised of two patches, posterior patch much shorter than anterior patch. Head: Finely punctate; interocular depressions and frontal umbo moderately developed; eyes oval, moderately convex; width across eyes slightly narrower than width across pronotum (40:43); antenna (fig. 218) shorter than length of pronotum (30:38). Thorax: Pronotum slightly longer than broad (43:48), disc finely punctate and very finely microsculptured, subapical depression poorly defined, side margins moderately arcuate; elytra moderately convex, depth at humerus 25, greatest depth in posterior half 30. Abdomen: Posterior margin of female pygidium evenly arcuate.

VARIATION: The specimens examined were quite homogeneous.

NATURAL HISTORY: Specimens have been collected in January, March, June, and July; from 100 to 500 m in altitude. Two specimens were collected on Croton , another by beating foliage from a flowering tree.

DISTRIBUTION (map 27): Known only from central Costa Rica.

ETYMOLOGY: The specific epithet cohibilis is a Latin adjectival that translates as terse. I refer to the abbreviated condition of the posterior patch of the elytral middiscal setal tuft.
