Campylomyza lapponica, 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 : 378

Campylomyza lapponica spec. nov.

( Figs 8–9 )

Diagnostic description: Many of the diagnostic characters used in the serrata group are especially pronounced in Campylomyza lapponica . The medial gonocoxal bridges, which strongly project both posteriorly (←) and dorsomedially (←), have conspicuously large microtrichia ( Fig. 8 ); the dorsal gonocoxal bridge is very narrow and strongly projects anteriorly (←, Fig. 8 ); the gonostyli are strongly convex posteriorly (←) and strongly excavated ventromedially ( Fig. 8 ); the tegminal shoulders are distinct (←) and the tegminal processes are of considerable length ( Fig. 9 ). While the gonostyli in the other species of the serrata group are thick, especially in the lobe-bearers, those of C. lapponica are laterally compressed–a peculiarity not apparent in Figure 8 . Other diagnostic characters of this species are as follows. The ninth tergite is narrow ( Fig. 8 ). The ventral emargination of the gonocoxites is moderately deep (i.e. the ventral bridge is rather long) and reinforced by a broad, bare sclerotized rim basally ( Fig. 8 ). The parameral apodemes are short ( Fig. 9 ). The aedeagal head is medium-sized ( Fig. 8 ).

Etymology: The Latin adjective lapponica refers to the distribution of this species in Lapland (lat. Lapponia).

Distribution: North Sweden (Pite Lappmark, Norrbotten).
