Meigen, 1818

Species Guides

Gonomyia is a of crane flies in the Limoniidae, established by Meigen in 1818. The genus contains numerous organized into multiple subgenera, including Gonomyia, Gonomyina, Idiocerodes, Leiponeura, Megalipophleps, Neolipophleps, Paralipophleps, Prolipophleps, and Teuchogonomyia. Fossil evidence from Cretaceous amber deposits in Spain and Myanmar indicates the genus originated by at least the Upper Albian, approximately 100 million years ago. spans multiple continents with modern records from Europe, Asia, and the Americas.

Identification

Identification to level requires examination of male terminalia, which are frequently illustrated in taxonomic revisions. Subgenera are distinguished by combinations of antennal segmentation, wing venation patterns, and genitalia . For example, the fossil subgenus Iberiana has 10-segmented while Cretagonomyia has 13-segmented antennae.

Cretaceous fossil record

Two new subgenera and were described from Cretaceous amber in 2022: Gonomyia (Iberiana) penalveri from Spanish amber (Upper Albian) and Gonomyia (Cretagonomyia) burmitica from Kachin amber (Lowermost Cenomanian). These represent the oldest confirmed records of the and provide evidence for its early evolutionary diversification.
