The tribu Optatini Champion, 1907 is composed of small to large-sized (2,3-
18,3 mm) weevils beetles, characterized by to have: rhomboidal or suboval body,
covered with scales variegated, nearly everywhere of the body or forming points and
spots; the mandibles toothed on the their inner edge; the prostern generally strongly
grooved down the middle, and with absent prosternal spine in the male; the anterior
coxae contiguos to broadly separated; the femora sharply dentate or denticulate; the
tibiae dentate ucinate; the tarsal claws generally united on base. The genera of this
tribe are associated with the botanical genera Annona L. (Annocaceae) and
Pentagonia Bentham (Rubiaceae). The geographical distribuition of the group is little
know, and it is restricted to Neotropical region (México, Guatemala, Honduras, Costa
Rica, Panamá, Colômbia, Venezuela, Trinidade and Tobago, Guiana Francesa,
Brasil, Equador, Peru, Bolívia and Argentina). The redescription and the phylogenetic
of the genera of Optatini are presented based on new characters discovered during
the study, and on others already found in the literature. Eleven genera were
redescribed: Costovia Casey, 1922, Lydamis Pascoe, 1889, Pardisomus Pascoe,
1889, Pseudoptatus Champion, 1907, Tripestes Casey, 1922, Pistus Faust, 1894,
Sympages Pascoe, 1889, Eurypages Pascoe, 1872, Telemus Pascoe, 1889,
Macroptatus Heller, 1906, and Optatus Pascoe, 1889. Only Parasyprestia were not
redescribed. All the twelve genera can be identified by key provided. All the
descriptions include illustrations to make easy the identification. Lectotypes are
designated to species Costovia brunnea, Lydamis conicicollis, L. semiluctuosus,
Pardisomus geniculatus, P. multiguttatus, P. rufescens, Pseudoptatus morio e Pistus
niveus. New dates about geographical distribuition are provided, being Lydamis
reported for the first time from the Provincie of Guanacaste (Costa Rica), Rondônia,
Mato Grosso Sul, São Paulo, Rio de Janeiro and Santa Catarina States (Brazil),
Archinamiza (Peru), Department of Beni (Bolívia); Pardisomus from Nouveau
Chantier (French Guiana), Province of Pastaza (Equador); Pistus from Espírito Santo
(Brazil), Pichincha (Equador), Lima and Madre de Dios (Peru), La Paz (Bolivia);
Sympages from Guanacaste (Costa Rica); Eurypages to Tocantins and Goiás
(Brazil); Telemus from French Guiana, Pará, Bahia, Goiás, Distrito Federal, Minas
Gerais, Espiríto Santo, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul
(Brazil), Department of Paraguari (Paraguai); Macroptatus to Guanacaste (Costa
Rica); Optatus from the Department of Jalisco (Mexico), Quiché and Baja Vera Paz
Departmentes (Guatemala), Guanacaste and Heredia (Costa Rica). The cladistic
analysis, based on 45 characters, found not support to monophyly of Optatini,
resulted that Optatini is a group comprising six branch (the genera Costovia,
Lydamis, Pardisomus and Pseudoptatus, and the branch Sympages and Eurypages). |
