Aphelocerus extensivus , new species Figures 37 , 66 , 158; map 27

HOLOTYPE: Female. Guatemala, Zapote (El Zapote) G. C. Champion ( BMNH). (Specimen point mounted; sex label affixed to paper point, white, machine printed; support card; locality label, white machine printed; holotype label, red, machine and hand print­ ed.)

PARATYPES: Five specimens. Two from the same locality as the holotype ( BMNH, 1; WOPC, 1). El Salvador: San Salvador: Quetzaltepeque , 500 m, 19­VI­1963, D. Q. Cavagnaro & M. E. Irwin ( WOPC, 2) ; 8­VII­ 1960, J. & B. Bechyne ( IZAV, 1) .

DIAGNOSIS: The posterior patch of the elytral setal tuft is narrowly extended posteriorly (fig. 37), and the sutural tuft is elongat­ ed. These characteristics will distinguish the members of this species from other members of the yungas species group.

DESCRIPTION: Size: Length 4.9–6.0 mm; width 1.8–2.2 mm. Integument: Piceous. Vestiture: Integument vested with predominately pale setae, few dark setae; metepisternal, sutural, and elytral middiscal tufts well developed; sutural tuft particularly elongat­ ed; elytral discal tuft bipartite; setae of anterior patch directed toward epipleuron, setae of posterior patch directed posteriorly, middiscal elytral setal tuft notably extended pos­ teriorly. Head: Width across eyes feebly narrower than width across pronotum (30:33), coarsely, densely punctated; interocular depression and frontal umbo shallow; eyes subspherical, moderately convex; antenna as in figure 66. Thorax: Pronotum near equal in width and length (33:34); narrower than width of elytra across humeri (26:33); finely punctate, side margins boldly arcuate, feebly incised by subapical depression, elytral depth at humerus 18, greatest depth in posterior half 21. Abdomen: Pygidium with posterior margin evenly convex. Male genitalia: As in figure 158.

VARIATION: Except for the body size, these beetles did not vary appreciably.

NATURAL HISTORY: The El Salvador specimens were collected in June (500 m) and July.

DISTRIBUTION (map 10): From southern Guatemala to central El Salvador.

ETYMOLOGY: The specific epithet is a Latin adjective meaning ‘‘stretch out’’. I refer to the extended condition of the posterior patch of the elytral middiscal setal tuft.
