New species and new records of Smicraulax Pierce 1908 and Cionomimus Marshall 1939 from Central America (Curculionidae Curculioninae Anthonomini)

Abstract

Five new species of Anthonomini associated with the mistletoe genus Phoradendron (Viscaceae) are described. Smicraulax nigrinus new species, is described from Guatemala, Honduras and Panama (type locality, Panama, Chiriqui, Boquete [5.7 km NE]). Distinguishing features are the shiny black integument with aeneous reflection, dorsally glabrous except for patches of white scales medially at base of pronotal disk and on scutellum, and moderately deeply, densely punctate pronotal disk. Smicraulax otidocephaloides new species, is described from Panama (type locality, Panama, Chiriqui, Boquete [5.8 km NE]). Distinguishing features are the shiny black integument lacking aeneous reflection, dorsally glabrous except for patches of white scales medially at base of pronotal disk, sparsely across basal margin of pronotal disk, and on scutellum, and very sparsely and finely punctate pronotal disk. Smicraulax ephippiatus new species, is described from Costa Rica (type locality, Cartago, Cerro de la Muerte, Villa Mills). Distinguishing features are the scattered elongate, narrow, white scales on the dorsal surface concentrated into patches along midline of pronotal disk and on scutellum, and the “saddled” appearance in lateral view. Smicraulax nigrinus and S. otidocephaloides have been collected associated with Phoradendron; there is no natural history information on S. ephippiatus. Cionomimus hansoni new species, is described from Costa Rica (type locality, Cartago, Cerro de la Muerte, Villa Mills). Distinguishing features are the slight cruciform swelling on the pronotal disk, the pattern of elytral tubercles, arid form of the aedeagus. Cionomimus bimaculatus new species, is described from Panama (type locality, Panama, Chiriqui, Boquete [5.7 km NE]). Distinguishing features are the bimaculate elytra and short, almost straight rostrum which is abruptly inserted onto the frons. New records of Cionomimus brevis (Champion 1903) in Costa Rica, Guatemala, Honduras and Panama, and C. championi Burke 1981 in Guatemala also are given. © 1997, Taylor & Francis Group, LLC.
