A generic reclassification of the Neotropical Erodiscini, employing new morphological characters, and based on cladistic analysis, is presented. The 98 recognized species are assigned to eight genera, five of which are new: PIMELERODIUS, gen. n. (type-species, Erodiscus motacilla Boheman, 1843), ECNOMORHINUS, gen. n. (type-species, Ecnomorhinus quasimodus, sp. n., PROSICODERUS), gen. n. (type-species, Erodiscus scolapax Faust, 1894); SICODERUS), gen. n. (type-species, Lixus antilope Fabricius, 1801); LANCEARIUS, gen. n. (type-species, Atenistes longirostris Pascoe, 1870). The following 44 species are new (type-localities parenthetic); Erodiscus caruaru, sp. n. (Caruaru, Pernambuco, Brazil); Pimelerodius sulcatipennis, sp. n. (Campinarana, Bahia, Brazil); P. reichardti sp. n. (Rio Solimoes, Amazonas, Brazil); P. pascoei (Silvestre, Rio de Janeiro, Brazil); P. birai sp. n. (Rio de Janeiro, Rio de Janeiro, Brazil); Ecnomorhinus quasimodus, sp. n. (Bogota, Cundinamarca, Colombia); Prosicoderus gyllenhali, sp. n. (Cayenne, French Guiana); P. bohemani sp. n. (Chambireyacu, Huallaga, Peru); P. germari. sp. n. (Estiron, Rio Ampiyacu, Loreto, Peru); P. xingu sp. n. (Xingu, Mato Grosso, Brazil); P. coronatus, sp. n. (Juruti, Para, Brazil); Sicoderus brevirostris, sp. n. (Cascavel, Ceara, Brazil); S. labidus, sp. n. (Santa Rosa, Putumayo, Colombia); S. matuete, sp. n. (Tefe, Amazonas, Brazil); S. perpolitus, sp. n. (Colombia); S. bicolor, sp. n. (Rancho Grande, Aragua, Venezuela); S. bondari. sp. n. (Linhares, Espirito Santo, Brazil); S. tumidipectus, sp. n. (Caruaru, Pernambuco, Brazil); S. exilis, sp. n. (Yarinha-Cocha, Rio Ucayali, Loreto, Peru). S. gracilis, sp. n. (Baixo Cauaburi, Amazonas, Brazil); S. cracens sp. n. (Caracas, Venezuela); S. petilus. sp. n. (Santarem, Para, Brazil); S. subcoronatus sp. n. (Linhares, Espirito Santo, Brazil); S. hirsutus, sp. n. (12 miles W of Santa Maria, Magdalena, Colombia), S. coroni, sp. n. (Bartica, Mazaruni-Potaro,, Guyana); S. prolatus sp. n. (Natal, Rio Grande do Norte, Brazil); S. apicalis, sp. n. (Pedra Azul, Minas Gerais, Brazil); S. remotus, sp. n. (Saint Vincent, Lesser Antilles); S. propinquus, sp. n. (Mustique Island, Grenadines, Lesser Antilles); S. contiguus, sp. n. (Saint Vincent, Lesser Antilles); S. championi, sp. n. (Samana, Dominican Republic), S. truncatipennis sp. n. (Port au Prince, Haiti); S. schoenherii, sp. n. (4 km SE Rio Limpio, La Estrelleta, Dominican Republic); S. sleeperi, sp. n. (Cayamas, Cuba); S. insidiosus, sp. n. (20 km from Ucayali on Rio Calleria, Colonia Calleria, Loreto, Peru), S. delusor, sp. n. (Paraiso, Canal Zone, Panama); S. inermis, sp. n. (Tefe, Amazonas, Brazil); S. abbreviatus sp. n. (San Martin, San Martin, Peru), Hammatostylus exiguus, sp. n. (Barro Colorado Island, Canal Zone, Panama); H. inhumeralis, sp. n. (Tarapoto, San Martin, Peru); H. erebus, sp. n. (Forte Principe da Beira, Rondonia, Brazil); H. vix, sp. n. (Cochabamba, Bolivia); H. difficilis, sp. n. (Utinga, Belem, Para, Brazil); H. consimilis, sp. n. (Igarape Belem, Rio Solimoes, Amazonas, Brazil). The following new synonyms are established: Erodiscus filirostris (Chevrolat)=E. scutellaris (Chevrolat)=E. denticollis (Pascoe); Pimelerodius gallinago (Kirsch) =P. motacilla (Boherman); Pimelerodius variabilis var. niger (Hustache)=P. variabilis (Hustache); Pimelerodius nigricornis (Hustache)=P. rectirostris (Hustache)=P. gryphus (Boheman); Sicoderus alutaceus (Hustache)= S. distinguendus (Hustache); Lancearius mycterius (Monte)= L. longirostris (Pascoe); Ludovix albipennis. Monte=L. fasciatus Gyllenhal. Two species, formerly placed in the Erodiscini, are removed from the tribe: Erodiscus gazella (Fabricius) returns to be genus Myrmex (Otidocephalini); Erodiscus grallator Gyllenhal (Oriental species ?) cannot be maintained in the Otidocephalinae and is tentatively assigned to the Hylobiinae. A discussion of the general morphology of the tribe is presented and important structures are discussed and illustrated. The presence of a stridulatory apparatus (elytro-femoral type) is reported fo
