Novas espécies de Blepharoneura Loew, 1873 (Diptera: Tephritidae, Blepharoneurinae) no Brasil Central com chave de identificação para o grupo poecilosoma

Abstract

Blepharoneurinae consists of four living genera: Baryglossa, Blepharoneura, Ceratodacus and Hexaptilona, and the extinct genus Problepharoneura. This subfamily corresponds to the most basal clade of Tephritidae. Blepharoneura is a neotropical genus with highly specific species about host colonization, being Cucurbitaceae the single family of host plants reported for these flies. From a survey for fruit flies with McPhail traps in a commercial orchard of guava in the locality Gleba Santa Terezinha, municipality of Itaporã, state of Mato Grosso do Sul, and in the locality Reserva Florestal Picadinha, municipality of Dourados, state Mato Grosso do Sul, Brazil, species of Blepharoneurinae were obtained. From these specimens, two new species of the genus Blepharoneura were described, one belonging to the group poecilosoma: Blepharoneura n. sp. 1, and the other to the femoralis group: Blepharoneura n. sp. 2. These are the first species of Blepharoneura described from adults sampled from Central Brazil, and the first record of a species of Blepharoneura from the poecilosoma group in Brazil. In this work, keys for identification of species for both groups: poecilosoma and femoralis are presented.
