ABSTRACT

Sumichrastia Townsend, 1916, and Myioscotiptera Giglio-Tos, 1893, monotypic genera of Dexiini restricted to the Neotropical Region, are revised. A redescription and photographs of the female holotype of Sumichrastia aurea (Giglio-Tos, 1893), in addition to the first recognition, description and photographs of the male are given. This genus belongs to the group of Dexiini with spine-like setae on the abdomen. Furthermore, a redescription and photographs of male holotype are given for Myioscotiptera cincta Giglio-Tos, 1893, in addition to a new specific synonym: Oberonomyia palpalis Reinhard, 1964 new junior synonym of M. cincta. Updated diagnoses are given for Sumichrastia and Myioscotiptera to help differentiate them from the other Dexiini genera. Finally, a brief biography of the collector of both holotypes, the Swiss naturalist François Sumichrast, is given.

摘要

Sumichrastia Townsend, 1916 和Myioscotiptera Giglio-Tos, 1893，仅限于新热带地区的 Dexiini 单型属，已进行修订。除了对雄性Sumichrastia aurea的首次识别、描述和照片之外，还对雌性 Sumichrastia aurea 正模进行了重新描述和照片（Giglio-Tos，1893）。该属属于 Dexiini 类，腹部有刺状刚毛。此外，还对Myioscotiptera cincta Giglio-Tos，1893 年的雄性正模进行了重新描述和照片，此外还提供了一个新的具体同义词：Oberonomyia palpalis Reinhard，1964 年M. cincta的新初级同义词。更新的诊断为Sumichrastia和Myioscotiptera有助于将它们与其他 Dexiini 属区分开来。最后，介绍了两种正模标本的收藏家、瑞士博物学家弗朗索瓦·苏米克拉斯特 (François Sumichrast) 的简介。
