Revisão taxonômica das espécies brasileiras de Notiphila FALLÉN, 1810 (Diptera: Ephydridae: Hydrelliinae)

Abstract

Notiphila Fallén (Diptera: Ephydridae, Hydrelliiane) is composed of small to medium-sized flies, usually grayish, with 140 species distributed throughout the biogeographical regions of the planet. They can be easily distinguished from other genera of Ephydridae by having: flat face with narrowed subcranial aperture, facial and paraffin bristles arranged in vertical, parallel series, pre-sutural dorso-central setae present, notopleural setae inserted at the same level, medium tibia with 3-4 bristles on the dorsal side, vein C extending to the R4+5 vein, and body with grayish-brown pruinosity. A taxonomic revision of the Brazilian species of Notiphila Fallén was carried out, here the genus was revised based on the external morphology and the male terminalia. The material was obtained from national and foreign zoological collections. An identification key was provided for the Brazilian species. A synonymy list, diagnosis, description, illustration of the male terminalia and geographical distribution was provided and provide an analysis of the synonyms. A discussion of the occurrence of some interesting morphological similarities was presented. Three species were reviewed, two were not included due to lack of type material and six new species were added to the genus: N. (Agrolimna) chrysis sp. nov. N. (Notiphila) aquila sp. nov.; N. (N.) aurata sp. nov.; N. (N.) evidens sp. nov.; N. (N.) marina sp. nov.; N. (N.) paranaensis sp. nov., In addition, the geographic record of the known species was expanded contributing to an increase in the knowledge of the genus.
