The first description of the larva of the crane fly genus Gonempeda Alexander, 1924 (Limoniidae: Chioneinae), with new information for understanding the phylogenetic relationships of the genus

Last instar larvae of two species of the genus Gonempeda Alexander, 1924, the palearctic G. flava (Schummel, 1829) and nearctic G. burra (Alexander, 1924), are described and illustrated for the first time for the genus. The pupa of G. burra is also newly described and compared to the pupa known previously for G. flava. Distinguishing characteristics of the immature stages allowing separation of this genus from other Chioneinae are presented, and the aquatic and semi-aquatic habitats used by the immatures are summarized. Characters of the larvae and pupae indicate that the genus Gonempeda belongs in a clade with Ormosia Rondani, 1856, Rhypholophus Kolenti, 1860 and Scleroprocta Edwards, 1938, but the exact relationships remain unresolved.
