Clerus immarginatus Chevrolat, 1874: 297 . LEC­ TOTYPE. Female. Here selected. Nova Granada (5 Colombia), Magdalena (MNHN). (Specimen point mounted; sex label affixed to paper point, white, machine printed; support card, white; identification­locality label, light green, cursive; Paris Museum­Chevrolat collection label, white, with green mark on margin, machine printed; MNHN repository label, white, machine printed; lectotype label, red, machine and hand printed.) NEW COMBINATION. Chevrolat (1876: 14). Barr (1976: 18).

DIAGNOSIS: The pronotum is distinctly elongate (fig. 39), the elytron is particularily convex in posterior half (fig. 40), and the humeral umbo of the elytra is particularly well developed (as in A. coactus , n.sp., fig. 10).

DESCRIPTION: Size: Length 4.5–6.0 mm; width 1.5–2.3 mm. Integument: Black. Vestiture: Head, prothorax, elytron, and protibia vested perdominantly with dark setae, pterothorax, femur, and meso­metatibiae vested predominantly with pale setae; tarsi vested with dark setae, elytral discal tuft comprised of one diagonal elongate patch whose setae are decumbent towards the anterior. Head: Width across eyes slightly narrower than width across pronotum (30:32), finely and sparsely punctate; interocular depression and frontal umbo prominent, eyes subspherical, moderately convex; antenna as in figure 76. Thorax: Pronotum distinctly elongate (32: 37), considerably narrower than width across humeri (32:37), finely punctate, sides feebly convex, subapical depression faintly indicat­ ed; elytra (fig. 242) strongly convex in posterior half, depth at humerus 15, greatest depth in posterior half 18, humeral tumes­

cence particularily prominent. Abdomen: Posterior margin of pygidium evenly arcuate in both sexes. Male genitalia (fig. 139): Parameres explanate.

VARIATION: The specimens examined did not vary appreciably.

NATURAL HISTORY: The specimen examined from Peru was collected in May.

DISTRIBUTION (map 13): Known only from the highlands of Colombia and Peru.

MATERIAL EXAMINED: I examined various specimens, four were from Colombia: Magdalena: Cundinamarca: Bogota. Specimens are deposited in MNHN and WOPC.
