HOLOTYPE: Female. Costa Rica, Punt., Monteverde , 20–24 Jun 1986, W. Hansen, G. Bohart ( AMNH). (Specimen point mounted, sex label affixed to paper point, white, machine printed; support card, white; locality label, white, machine printed; AMNH repository label, white, machine printed; holotype label, red, machine and hand printed.)

PARATYPES: Nineteen specimens. Costa Rica: Puntarenas: Monteverde, Cloud forest , 9–12­VI­1986, F. T. Hovore ( WFBC, 1): San Luis , 2–8­VIII­1996, L. M. La Pierre ( JNRC, 6; WOPC, 3) ; 26­VII–1­VIII­1996, L. La Pierre ( JNRC, 2) ; San Luis valley , 1­VII­ 1989, F. Hovore ( WFBC, 1) ; San Luis , 1040 m, 24­VIII–15­IX­1992, F. A. Quesada ( INBC, 1) ; Monteverde, Pension Quetzal , 22–24­IV­1985, F. T. Hovore ( WOPC, 1) ; 26­ V–3­VI­1984, E. Riley, D. Rider, and D. Le Doux ( LSUC, 1; WOPC, 1) ; 1500 m, 11–13­ IV­1996, E. Giesbert ( WOPC, 1) ; 21–26­V­ 1979, J. M. and B. A. Campbell ( WOPC, 1) .

DIAGNOSIS: Specimens of this species closely resemble those of A. arenatus , n. sp., from which they may be distinguished by having the anterior patch of the middiscal setal tuft only slightly larger than the posterior patch. In A. arenatus , n.sp., specimens the anterior patch is twice as large as the posterior patch.

DESCRIPTION: Size: Length 4.0– 5.2 mm; width 1.8–2.3 mm. Integument: Cranium, pronotum, pterothorax, abdomen cyanescent, elytra piceous. Vestiture: Head, prothorax, elytra, and protibia vested predominantly with dark setae, pterothorax, femora, and meso­metatibiae vested predominantly with pale setae; tarsi vested with dark setae; setal tuft of elytral disc as in figure 177. Head: Width across eyes feebly narrower than width across pronotum (35:37), finely punctate; interocular depression and fronal umbo shallow; eyes subspherical, moderately convex; antenna as in figure 72. Thorax: Pro­ notum slightly longer than wide (40:37), disc finely punctate, subapical depression faintly indicated, considerably narrower than width of elytra across humeri (24:32), side margin moderately arcuate, feebly incised by subapical depression; elytral depth at humerus 22, greatest depth in posterior half 30, humeral tumescence prominent. Abdomen: Male pygidium posterior margin evenly narrowed, evenly arcuate in females. Male genitalia: Aedeagus short, parameres as in figure 214.

VARIATION: The available specimens did not vary appreciably.

NATURAL HISTORY: Specimens were collected during May, June, July, and August at altitudes ranging from 1040 to 1500 m.

DISTRIBUTION(map 21): Known only from northwestern Costa Rica.

ETYMOLOGY: The trivial name monteverde is a noun in apposition and refers to type locality.
