Campylomyza appendiculata, 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 : 377-378

Campylomyza appendiculata spec. nov.

( Figs 5–7 )

Diagnostic description: Campylomyza appendiculata is unmistakably identified by the following combination of characters: the gonostyli have a large dorsal lobe (←, Fig. 5 ); the largely parallel-sided tegmen has small shoulders (←) and conspicuously long parameral apodemes (←, Fig. 7 ); the aedeagal head is more densely covered with microtrichia than in the other species of the serrata group (←, Fig. 7 ); and the medial bridges of the gonocoxites project posteriorly (←, Fig. 6 ). Other diagnostic characters of C. appendiculata are as follows. The ninth tergite is moderately wide to narrow ( Fig. 6 ). 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; the medial bridges strongly project dorsomedially (←); and the dorsal bridge, which is narrow, reaches far anteriorly ( Fig. 6 ). The gonostylus is strongly convex posteriorly, narrowly rounded apically, and strongly excavated ventromedially ( Fig. 6 ). The aedeagal head is mediumsized ( Fig. 6 ).

Etymology: The Latin adjective appendiculata means elongated, with reference to the unusually long parameral apodemes.

Distribution: South Norway (inner Hordaland), south to central Finland (Regio aboensis, Satakunta, Savonia australis, Karelia borealis), Netherlands (Noord- Brabant), north to central Japan (Hokkaido, Honshu).
