Campylomyza zwii, Jaschhof, 2015

Jaschhof, Mathias, 2015, Morphological re-examination reveals that Campylomyza serrata JASCHHOF, 1998 is a complex of five cryptic species (Diptera: Cecidomyiidae, Micromyinae), Beiträge Zur Entomologie = Contributions to Entomology 65 (2), pp. 373-381 : 379-380

Campylomyza zwii spec. nov.

( Figs 12–13 )

Diagnostic description: Campylomyza zwii is clearly distinguished from the other species of the serrata group in Europe by two characters: the tegminal processes, which are turned posteriorly, form the apex of the tegmen (←, Fig. 13 ), and the blunt-ended aedeagal head is so large that it occupies almost all the ventral gonocoxal emargination (←, Figs 12–13 ). Campylomyza spinata from the Far East of Russia is similar in this respect, but has – unlike all the other serrata -like species – the medial gonocoxal bridges equipped with 2 processes ( JASCHHOf 1998a: Etymology: This species is named after Thorsten (“Zwi”) Zwinger, Neuenkirchen near Greifswald, for his support of my work on gall midges.
