Abstract

Two uncommon genera of Steganinae (Drosophilidae) are herein studied based on material from the Neotropical Region, Pseudiastata Coquillett and Hyalistata Wheeler. Additional records for Pseudiastata Coquillett are provided, including the redescription of the species Pseudiastata brasiliensis Costa Lima, originally described in 1937. An update to the morphological nomenclature is also proposed, as well as a lectotype and some paralectotype designations. Moreover, the genus Hyalistata Wheeler, for which two new species are described (Hyalistata cerradensis sp. nov. and Hyalistata emas sp. nov.) is first recorded in Brazil. We present photographs and detailed illustrations of the terminalia of all species described here.

摘要

本文基于来自新热带地区的Steganinae（果蝇科）的两个不常见属，即Pseudiastata Coquillett 和 Hyalistata Wheeler 的材料进行研究。本文还提供了对 Pseudiastata Coquillett 的更多记录，包括对最初于 1937 年描述的巴西 Pseudiastata brasiliensis Costa Lima 进行重新描述。本文还提出了形态命名法的更新，以及一个模式标本和一些副模式标本的指定。此外，首次在巴西记录到了 Wheeler 属的两个新物种，即Hyalistata cerradensis sp. nov. 和 Hyalistata emas sp. nov.。本文还提供了这里描述的所有物种的末端结构的照片和详细说明。
