Campylomyza serrata, JASCHHOf, 1998

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 : 374

Campylomyza serrata group

Species of the serrata group are characterized by the tegmen that has a pair of finely serrate processes ( JASCHHOf & JASCHHOf 2009). The serration is not obvious in all the specimens studied and is perhaps variable within a species. According to the orientation of these processes and to the size of the aedeagal head, two subgroups can be distinguished. In Campylomyza spinata and C. zwii , which make up one of the subgroups, the processes are turned posteriorly, so as to form the apex of the tegmen (←, Fig. 13 ), and the aedeagal head is large (←, Fig. 13 ). In the other subgroup, which contains C. angulata , C. appendiculata , C. lapponica , and C. serrata , the tegminal processes are situated subapically dorsomedially in a longitudinal direction (←, Fig. 11 ), and the aedeagal head is small- (←, Fig. 10 ) to medium-sized (←, Fig. 7 ). Another peculiarity of the serrata group is that the medial gonocoxal bridges, which in Campylomyza are usually unmodified, have the tendency to project dorsomedially, either in their entirety (←, Fig. 6 ) or by sending out narrow processes ( JASCHHOf 1998b: Fig. 58a).
