RESUMO:

Geniatini Burmeister is one of the tribes of Rutelinae, with 346 species and 2 subspecies described in 13 genera, being recorded from South Mexico to South America and in the Lesser Antilles, in the Caribbean. Until this moment, there are no hypotheses about the phylogenetic relationships of Geniatini genera. Lobogeniates Ohaus has 35 described species, with records for Central and South America. Trizogeniates Ohaus has 31 described species, being recorded from Costa Rica to the north of Argentina and Paraguay. This study aimed to propose a phylogenetic hypothesis for Geniatini genera, to do a taxonomic review of Lobogeniates species, make a key and a catalog for the species of the genus, describe the new species of Lobogeniates and Trizogeniates, propose a phylogenetic hypothesis for the species of Lobogeniates, make a catalog and a key identification for the Brazilian species of Trizogeniates and update the geographical distribution of the genus. For the phylogenetic reconstruction of Geniatini, 196 morphological characters from 65 terminal taxa, 58 ougroups and 7 ingroups were used. The analysis with equal weights recovered the 13 geniatini Genera as: Rhizogeniates (Mimogeniates ((Microchilus (Bolax + Leucothyreus)) ((Heterogeniates (Evanos + Eunanus)) ((Xenogeniates + Geniatosoma) (Trizogeniates (Geniates + Lobogeniates)))))). Were described 27 new species, designated Lobogeniates sp.n.1–27. Were designated lectotype of L. bicolor Ohaus, L. brevior Ohaus, L. collaris (Burmeister), L. flavolineatus Ohaus, L. fuscopunctatus Ohaus, L. marronus Ohaus, L. nigripennis Ohaus, L. panamensis (Arrow), L. signatus (Burmeister). Neotype of L. apicalis Ohaus, L. catullus Ohaus, e L. tucumanensis (Camerano) were designated. Four new combinations were proposed, Geniates distans Burmesiter; G. immaculatus Camerano; G. panamensis Arrow and G. leptopus Frey were transferred to Lobogeniates. Lobogeniates catullus Ohaus is new synonym of L. fuscopunctatus Ohaus, L. elegans Ohaus is a new synonym of L. distans (Burmesiter) and L. panamaensis (Frey) is a new synonym of L. panamensis (Arrow). The cladistic analysis of Lobogeniates was composed of 66 terminal taxa, 61 ingroups and 5 utgroups. The analysis with implicit weights recovered the species of Lobogeniates as: Lobogeniates sp.n.21 ((((grupo bicolor) + ((grupo distans) + (grupo tucumanensis + grupo immaculatus))) + ((grupo collaris) ((Lobogeniates sp.n.14) + (grupo fuscopunctatus + grupo panamensis)))). Seven new species of Trizogeniates have been described, with new records for 12 species of the genus.
