Guides
Leptosyna
Leptosyna is a genus of gall midges in the family Cecidomyiidae, established by Kieffer in 1894. It belongs to the subfamily Porricondylinae and tribe Heteropezini. Members of this genus are small, delicate flies with reduced wing venation characteristic of the family. The genus is poorly documented in modern literature, with limited species-level information available.
Neostenoptera
Neostenoptera is a genus of gall midges (Cecidomyiidae) established by Meunier in 1902. For over a century, the genus was known only from two African records: one species described from copal (young amber) and another collected alive in the Congo. The 2016 discovery of Neostenoptera appalachiensis in Great Smoky Mountains National Park, Tennessee, marked the first New World record of the genus, extending its known distribution to eastern North America. The genus belongs to the tribe Heteropezini within the subfamily Porricondylinae.
