Aphelocerus calvus , new species Figures 90 , 153 ; map 22

HOLOTYPE: Male. Brazil, Sto. Paulo ’d Olivenca, Amazones, M. de Mathan ( MNHP). (Specimen point mounted, pygidium, sixth visible abdominal sternum, and machine printed sex label affixed to paper point; support card, white; locality label, white, machine printed; Paris Museum collection label, white, machine printed; holotype label, red, machine and hand printed.)

PARATYPES: None.

DIAGNOSIS: The extraordinary, elongate pronotum (23:30) distinguishes the members of this species; the width across the eyes is greater than the width of the pronotum (23: 24); the frontal setal tuft and the metepisternal tuft are present.

DESCRIPTION: Size: Length 5.0 mm; width 7.0 mm. Integument: Piceous. Vestiture: Frontal tuft moderately developed, metepisternal tuft well developed; anterior fascies of protibia vested with dark setae, tarsi vested with dark setae, profemora and remainder of legs, pterthorax, and abdomen vested with pale setae; dorsum vested with dark setae. Head: Genae and epicranium expanded, gena behind eyes wrinkled; interocular depression and frontal umbo indistinct; frons, epicranium, and gena very finely punctate; eyes subspherical, moderately convex; width across eyes feebly broader than width across pronotum (24:23); antenna (fig. 90) nearly as long as length of pronotum (28:30). Thorax: Pronotum conspicuously elongate (23:30); pronotum considerably narrower than width of elytra across humeri (23:27), side margins feebly arcuate, anterior transverse depression faintly indicated, elytra moderately convex, depth at humerus 10, greatest depth in posterior half 15; legs prominent, metafemur extended beyond elytral apex. Abdomen: Posterior margin of pygidium evenly arcuate. Male genitalia: Parameres acuminate (fig. 153).

DISTRIBUTION (map 22): Known only from the Amazonian region of Brazil.

ETYMOLOGY: The trivial name calvus (bald) is a Latin adjective used here to emphasize the lack of a setal tuft on the elytral disc.
