Aphelocerus naevius, OPITZ, 2005

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 : 81-82

Aphelocerus naevius , new species Figures 35, 36 , 64 , 116, 117 , 143 ; map 21

HOLOTYPE: Male. Honduras, Oco., 14 mi. NE Nueva Ocotepeque, 69009, 25­VII­1974, O’Briens & Marshall ( AMNH). (Specimen point mounted, sex label affixed to paper point, white, machine printed; paper point with antenna; support card; locality label, white, machine printed; AMNH repository label, white, machine printed; holotype label, red, machine printed; plastic vial with aedeagus.)

PARATYPES: Two specimens from the same locality as the holotype ( WOPC, 2).

DIAGNOSIS: The flecklike appearance of the setal tuft on the elytral disc (figs. 35, 36) will conveniently distinguish the members of this species. Also, the pronotal side margins (fig. 36) are boldly arcuate giving the pronotal disc a subspherical dorsal profile, a unique configuration of the pronotum in the batesi group.

DESCRIPTION: Size: Length 4.2–5.0 mm; width 1.7–1.8 mm. Integument: Cyanescent, except elytra piceous. Vestiture: Integument vested predominantly with dark setae; metepisternal, sutural, and elytral discal tufts well developed; latter consists of one cluster of posteriorly directed setae (fig. 35). Head: Width across eyes equal to width across pronotum (35:35), finely densely punctate; interocular depression and frontal umbo shallow; eyes subspherical, moderately convex; antenna as in figure 64. Thorax: Pronotum slightly longer than wide (37:35), narrower than width of elytra across humeri (35:47), disc finely punctate; elytral humeral umbo prominent; elytra feebly convex in posterior half, depth at humerus 15, greatest depth in posterior half 20. Abdomen: Female pygidium (fig. 116) trigonal, sixth visible abdominal sternum deeply incised (fig. 117); aedeagus (fig. 143) short, parameres feebly developed, ventral sinus three times longer than dorsal sinus.

VARIATION: The available specimens did not vary appreciably.

NATURAL HISTORY: The available specimens were collected by beating at 2103 m.

DISTRIBUTION: Known only from Honduras.

ETYMOLOGY: The specific epithet is a Latin adjective that means ‘‘with a mole or birthmark’’. I refer to the flecklike appearance of the elytral middescal setal tuft.
