OPITZ, WESTON, 2005, Classification, Natural History, And Evolution Of The Genus Aphelocerus Kirsch (Coleoptera: Cleridae: Clerinae), Bulletin of the American Museum of Natural History 2005 (293), pp. 1-128 : 73-75

Aphelocerus batesi , new species Figures 79 , 152 , 179 , 272 ; map 15

HOLOTYPE: Male. Brazil, Amazon , Ege (Tefe), Bates ( BMNH). (Specimen point mounted, pygidium, sixth visible sternum, spicular fork, and machine printed sex label affixed to paper point; support card; locality label, white, machine and hand printed; Fry Collection label, white, machine printed; holotype label, red, machine and hand printed; plastric vial with aedeagus.)

PARATYPES: Twenty­eight specimens. Nine specimens with the same locality information as the holotype ( BMNH, 5; WOPC, 4). Brazil: Matto Grosso: Diamantino, Fazenda Rio Arinos , X­1983, Eurides Furtado ( CMNH, 5; WOPC, 4) ; Para: ( BMNH, 1; WOPC, 1) ; Santarem ( ICCM, 1): Goias: Jatai , XI­1972, F. M. Oliveria ( WOPC, 1) ; Taperinha (1, ICCM) ; Amazonas: Itaituba ( MNHN, 1; DEIC, 1): Ceara: Serra de Baturite ( MNHN, 1): 4–16­XI, 1997, J. E. Eger, black light trap ( FSCA, 1) ; 5–17­X­1993, J. E. Eger, MV & black lights ( WOPC, 1) .

DIAGNOSIS: Specimens of this species superficially resemble those of A. immarginatus (Chevrolat) . In specimens of batesi , however, the elytral middiscal setal tuft (fig. 179) is more developed and the tegmen of the male genitalia is not sagittate as is the case in specimens of A. immarginatus (Chevrolat) .

DESCRIPTION: Size: Length 4.8–5.3 mm; width 2.0– 2.2 mm. Integument: Black. Vestiture: Head, prothorax, elytron, and protibia vested with predominantly dark setae, pterothorax, femora, meso­metatibiae vested with predominantly pale setae; tarsi vested with dark setae, elytal posterior patch of elytral discal setal tuft extended posteriorly. Head: Width across eyes slightly narrower than width of pronotum (22:24), finely punctate, interocular depressions and frontal umbo shallow, eyes subspherical, moderately convex; antenna as in figure 79. Thorax: Pronotum (fig. 272) feebly elongate (24:28), narrower than width of elytra across humeri (24:33), finely punctated, side margins moderately arcuate, subapical depression faintly indirected; elytra boldly convex in posterior half, depth at humerus 12, greatest depth in posterior half 18; humeral umbo prominent. Abdomen: Posterior margin of pygidium evenly arcuate to both sexes. Male genitalia: As in figure 152; ventral sinus particularily elongate.

VARIATIONS: The specimens examined did not vary appreciably.

NATURAL HISTORY: Specimens were collected in October and November ( Brazil); two with a black light trap.

DISTRIBUTION (map 15): Found most frequently in the environs of the Amazon Basin of Brazil.

ETYMOLOGY: The trivial name is a dedicated epithet in honor of the collector of the holotype, H. W. Bates.
