Revisão taxonômica do gênero Neorhinotora Lopes, 1934, e morfologia comparada da genitália masculina e protândrio da subtribo Rhinotorina (Diptera, Heleomyzidae, Rhinotorini)/

Abstract

The family Heleomyzidae includes 22 tribes, but only Rhinotorini and Diaciini occur in Brazil. Three genera of Rhinotorini are registered to Brazil: Rhinotora Schiner, 1868, Neorhinotora Lopes, 1934 and Rhinotoroides Lopes, 1934. The genus Neorhinotora is revised here based on morphology of external characters of the species and genitalia. The species N. mutica (Schiner, 1868), N. aristalis (Fischer, 1932), N. fonsecai Lopes, 1934, N. amapaensis Guimarães & Papavero, 1966 are redescribed. The species N. fonsecai has more similarities in relation to Rhinotora that in relation to the other species of Neorhinotora. For the first time the species N. aristalis and N. amapaensis are registered in the Central Amazonia. A dicotomic key is provided for the species of Neorhinotora, as well as illustrations for the male genitalia of the species. The male genitalias and protandrium of the other genera of the subtribe Rhinotorina are still studied. The male genitalia of the species Apophoneura inconspicua Malloch, Rhinotora pluricellata Schiner and of Rhinotoroides bifurcata Lopes are illustrated. Specimens of the two other subtribes of Rhinotorini, Anastomyza lateralis (subtribe 2) Malloch and Cairnsimyia excavata (subtribe 1) McAlpine, are analized for a comparison. The fusion of the tergite 6 with the sternite 8, and the tergite 6 totally surrounding the abdomen are present conditions in the four genera of Rhinotorina. The presence of cerci fused to the epandrium possibly is a sinapomorphy of Rhinotora, Neorhinotora and Rhinotoroides. The caracters of male genitalia and protandrium probably will be important to a future phylogenetic analysis within genera of Rhinotorini.
