The gibbera Group of the genus Bezzia Kieffer, subgenus Bezzia, is comprised in the Neotropical Region of at least 16 species, of which the following 11 species are described as new: araucana from Argentina; catarinensis from Brazil; globulosa from Puerto Rico; grogani from Colombia, Mexico and Panama; hondurensis from Mexico and Central America; jubata, leei and megatheca from Colombia; mesotibialis from Belize and Trinidad; pseudogibbera from Honduras and Panama; and setigera from Colombia and El Salvador. A key is presented for subgenera and species groups, and for the Neotropical species of the gibbera Group.
The Pantomorus viridisquamosus species group can be separated from other Pantomorus Schoenherr, because it has recumbent setae, slender antennae with funicular article 2 almost as long as 1, glabrous scutellum, indistinct humeri, and hind tibiae lacking corbel plate and with dorsal comb about as long as apical comb. It is composed of two species, P. viridisquamosus (Boheman) from central and northeastern Argentina, Uruguay, and southern Brazil, and P. obrieni Lanteri sp.nov. from northeastern Argentina and southern Brazil. Pantomorus obrieni differs from P. viridisquamosus because it is smaller and has carinate scales, shorter and wider setae, more conical rostrum, and more convex eyes, pronotum and elytra. The female of P. viridisquamosus is redescribed and the male described (males are very infrequent). Line drawings and SEM illustrations of the diagnostic structures, and a distributional map are included.
