Fig. 13A

Diagnosis

The new species differs from all Neurepidosis described in the past by its gonocoxal synsclerite, whose ventral emargination has an unusually complex structure ( Fig. 13A ). In ventral view, the broadly sclerotized margins of the emargination appear to be double-layered, with both layers intertwined in a complicated way. Larvae and females of N. hartschimmelhofensis sp. nov. are unknown.

Etymology

The name refers to the type locality, Hartschimmelhof in southern Upper Bavaria, where the farmstead Gut Hartschimmel maintains a cultural landscape with extraordinarily rich biodiversity, thanks to many decades of practising extensive farming.

Type material

Holotype

GERMANY • ♂; Bavaria, Weilheim, Pähl , Hartschimmelhof ; 47°94′24″ N, 11°18′33″ E; 20 Jun.‒12 Jul. 2020; D. Doczkal and K. Grabow leg.; Malaise trap; nutrient-poor pasture; ZSM-DIP-42303-B09 .

Other characters

Male

BODY LENGTH. 1.4 mm.

HEAD. Eye bridge dorsally 1‒2 ommatidia long. Scape and pedicel brighter than flagellum. Length of flagellum unknown, only 10 flagellomeres retained; neck of fourth flagellomere 1.2 × as long as node (all flagellomeres are collapsed, the reason why the fourth is not illustrated here). Palpus 4-segmented, shorter than head height.

WING. Longer than body. Length / width ratio 2.8.

LEGS. Acropods not retained.

TERMINALIA ( Fig. 13A ). Posterior margin of ninth tergite almost straight, weakly sclerotized except for a small, sclerotized reinforcement medially. Gonocoxal synsclerite slightly broader than long (not considering the long dorsal apodemes that protrude beyond the anterior gonocoxal margin); ventral setae unusually sparse, confined mostly to posterior portions; ventral emargination narrow and unusually deep, below the emargination a more darkly pigmented area without setae or microtrichia; dorsoposterior portions only slightly protruding beyond ventroposterior portions. Gonostylus compact, barely twice as long as high, its apex narrowly rounded, covered with dense, large microtrichia. Tegmen strongly narrowed towards apex, with about 3 pairs of tiny, inconspicuous barbs subapically. Aedeagal apodeme massive, strongly sclerotized; its greatly extended base protrudes beyond anterior gonocoxal margin; apex weakly sclerotized, transitions seamlessly into tegminal apex.
