The Neotropical species of Pseudanthonomus Dietz (Coleoptera: Curculionidae)

Characters diagnostic of the genus Pseudanthonomus Dietz and of the 30 Neotropical species in the genus are described and illustrated. A key to the three genera of Anthonomini, including Pseudanthonomus, that contain species with 6 antennal funicular articles, and a key to the Neotropical species of Pseudanthonomus are also presented. The latter key includes two of the seven species from America north of Mexico that also occur in Mexico. Eight species are removed from Pseudanthonomus and placed in the genus Anthonomus in the following new combinations: A. apionoides (Champion); A. bellus (Hustache); A. cretaceus (Champion); A. curvicrus (Champion); A. guttatus (Champion); A. lituratus (Champion); A. nubilosus (Champion); A. pusillus (Hustache). Pseudanthonomus seriatus Hustache is transferred to the genus Phyllotrox in the new combination of P. seriatus (Hustache). Twenty-two new species of Pseudanthonomus are described: P. baryon (Venezuela); P. boson (Venezuela); P. electron (Brazil, Guatemala, Mexico); P. fermion (Brazil); P. gluon (Mexico); P. hadron (Brazil, Honduras, Mexico, Venezuela); P. lepton (Brazil); P. meson (Brazil); P. muon (Brazil, Panama, Trinidad, Venezuela); P. nucleon (Brazil, Colombia, Panama and Venezuela); P. neutrino (Brazil); P. neutron (Brazil); P. parton (Brazil); P. photino (Trinidad, Venezuela); P. photon (Cuba, Republica Dominicana [West Indies]); P. pion (Venezuela); P. positron (Mexico); P. proton (Colombia); P. quark (Brazil); P. selectron (Venezuela); P. tachyon (Brazil, Panama); P. tau (Mexico). Lectotypes are designated for Pseudanthonomus griseipilis Champion, P. canescens Faust, P. meridionalis Champion and P. carinulatus Faust. Anthonomus testaceus Boheman is transferred to Pseudanthonomus as P. testaceus (Boheman). The following are new synonyms: Pseudanthonomus canescens Faust (= P. indignus Faust), Pseudanthonomus testaceus (Boheman) (= P. meridionalis Champion).
