Type data. Two card mounted syntypes with the following labels were examined: 1) Attelabus conicollis , male, Type D. S. Chontales Janson [on card with specimen]; Type [circular label with red margin]; Chontales Nicaragua Janson; B.C.A. Col. IV.3, Attelabus conicollis Sharp, Sharp Coll. 1905 ­3­13. 2) Attelabus conicollis , female, Type Chontales Janson, sp. figured [on card with specimen]; Type [circular label with red margin]; Chontales Nicaragua Janson, B.C.A. Coll. IV.3. Attelabus conicollis Sharp. The male is here designated as the lectotype and the female as the allolectotype.

Size range. Male: 5.0 x 2.5 mm to 7.5 x 3.7 mm; Female 4.9 x 2.5 mm to 7.9 x 4.0 mm.

Description. Body red or brownish­red. Head with minute shallow punctures, with punctures more numerous around eyes; vertex and frons with weak median channel; eyes reniform, not protuberant, flush with surface of head. Rostrum slightly longer than head, bisulcate at dorsal base; densely punctured at base and dorsally beyond antennal insertions, more than twice as wide as frons at apex; postlabial area raised, with pair of short, bluntly pointed, divergent projections in male. Antennae inserted just behind middle in both sexes; club elongate­compact, shorter than funicle, middle and terminal segments nearly subequal in length, basal segment longer; funicular segment 1 ovo­globose, shorter than scape; segment 2 short, shorter than segment 1, clavate; segment 3 same as 2 but longer, segment 4 same as 3 but slightly shorter, segments 5–7 moniliform, subequal. Pronotum smooth, shiny, with minute irregularly spaced punctures; anterior collar weakly defined. Scutellum wide, about twice as wide as long, 5­sided; posterior margin weakly angulate at middle. Elytra longer than wide, widest at humeri; in dorsal view distinctly narrowed from humeri to apices, weakly depressed behind scutellum; humeri moderately protuberant, weakly oblique­angulate, with small denticle in both sexes, sometimes denticle indistinct; striae small, round, distinct throughout, larger and more deeply impressed at elytral base, inner rows forming weak line­like grooves at elytral base, posteriorly more widely spaced within strial row and more shallowly impressed; intervals flat, smooth, wide. Profemora evenly swollen in both sexes.

Distribution ( Fig. 8 ). This is a widespread species throughout Central America. It is recorded from Mexico, Belize, Guatemala, El Salvador, Honduras, Costa Rica and Panama.

Comments. The species is easily recognized by its relatively large size, reddish color and eyes that are flush with the surface of the head. (Figs. 72–75). Both sexes of this species usually have a very small humeral denticle although it is indistinct in some females.

Host plants. This species is associated with Psidium sp. and Eugenia sp. in the family Myrtaceae . Specimens have been taken from Psidium guineense Sw. and Psidium molle L. in Costa Rica. Vogt (1992) states that this species rolls the leaves of Psidium guajava L. and several species of Eugenia .
