title: Linnaeomyia hortensis gen. et spec. nov. (Diptera: Cecidomyiidae, Porricondylinae) from a backyard site in Öland, Sweden.
abstract: A new genus containing a single new species of Porricondylinae (Diptera: Cecidomyiidae) is described and named Linnaeomyia hortensis gen. nov., spec. nov. The sole known specimen of L. hortensis, a male, was Malaise trapped in a backyard site on the Baltic island of Öland, southeast Sweden, in summer 2014. Morphological evidence supports our hypothesis that Linnaeomyia is most closely related to Neurepidosis Spungis, 1987. Several male genital characters, notably the spine-bearing gonostyli and the vestigial ejaculatory apodeme, substantiate the generic distinctiveness of L. hortensis. Although a backyard discovery, L. hortensis is unlikely to be a synanthropic species.
