摘要

Stenomicra Coquillett, 1900 comprises forty species worldwide, most know in the Afrotropical and Australian regions. In the Neotropical region, there are nine species of Stenomicra, and in South America, only three species are known. In the manuscript, eight new species of Stenomicra are being described from South America: Stenomicra (Stenomicra) dorsimaculata sp. n., Stenomicra (Stenomicra) frontalis sp. n., Stenomicra (Stenomicra) geovaniae sp. n., Stenomicra (Stenomicra) limeirai sp. n., Stenomicra (Stenomicra) longiseta sp. n., Stenomicra (Stenomicra) paraensis sp. n., Stenomicra (Stenomicra) rafaeli sp. n. and Stenomicra (Podocera) cuscana sp. n.. A geographical records map of the new species, plates with photographs of adults and terminalia, and a dichotomous key illustrated with photographs of the holotypes of the Neotropical species of Stenomicra are also provided. These discoveries advance the study and knowledge of Stenomicra in the Neotropical Region and mark the first records of this genus in Peru and the subgenus Podocera in South America.
