Diagnosis

Lamellepidosis luderbuschensis sp. nov. differs from L. spungisi in several details of the male terminalia ( Fig. 20A ). The most obvious difference concerns the gonostylus, whose apex is strongly flattened and pointed in the new species (↓ 1) versus slightly flattened and rounded in L. spungisi ( Jaschhof & Jaschhof 2017: fig. 9a). Another distinction is that the tegmen of the new species is markedly narrowed towards the apex (↓ 2), whereas that of L. spungisi is parallel-sided ( Jaschhof & Jaschhof 2017: fig. 9a). A third difference concerns the gonocoxal synsclerite whose ventroposterior portions are broad and blunt-ended in the new species (↓ 3), whereas they are narrower and extended into rounded lobes in L. spungisi ( Jaschhof & Jaschhof 2017: fig. 9a). Larvae and females of L. luderbuschensis are unknown.

Etymology

The specific epithet is derived from the type locality, the Gewann Luderbusch near Malsch in Baden-Württemberg. The Luderbusch emerged as one of the most productive areas for mycophagous cecidomyiids sampled in the course of GBOL III: Dark Taxa, probably because of the outstanding diversity and quality of the natural habitats found there.

Other characters

Male

BODY LENGTH. 2.0‒ 2.3 mm.

HEAD. Eye bridge dorsally 3‒4 ommatidia long. Antenna longer than body; scape and pedicel brighter than flagellum; 14 flagellomeres; circumfila present on flagellomeres 1‒11; neck of fourth flagellomere 2.3× as long as node ( Fig. 20B ). Palpus 4-segmented, markedly longer than head height.

THORAX. Both anepisternum and anepimeron sparsely setose.

WING. Longer than body. Length/ width ratio 2.9. Venation as in L. spungisi ( Jaschhof & Jaschhof 2017) .

LEGS. Claws crescent-shaped, with 1 large tooth basally. Empodia ¾ as long as claws.

TERMINALIA ( Fig. 20 ). Gonocoxal synsclerite: ventral emargination U-shaped, with broad sclerotized margin anteriorly; processes large, thin-membranous, glabrous; a large, narrowed setose portion ventroanteriorly. Gonostylus in ventral view 3 × as long as broad, broadest at about midlength; a large plate-like tooth arising from a short process subapicoventrally; outside with setae of various lengths; inside sparsely setose, including 2‒3 long subapical bristles. Aedeagal apodeme longer than gonocoxae, moderately sclerotized, brodened apically. Tegminal apex membranous, slightly incised.
