Diagnosis

Camptomyia serrata sp. nov. differs from congeneric species in the male terminalia structures, notably the dorsal parameres whose margins are serrate apicolaterally due to the presence of 5‒6 small barbs (↓ 1, Fig. 11E ). A further peculiarity is the ninth tergite whose posterior margin is indented in an unmistakable manner, and whose cordate central portion, which is darkly pigmented and sparsely setose, has a sclerotized median axis ending in an inverse T-shape (↓ 2, Fig. 11C ). Larvae and females of the new species are unknown.

Etymology

The specific epithet, the Latin adjective for ‘serrate’, refers to the peculiar outline of the parameres.

Type material

Holotype

GERMANY • ♂; Baden-Württemberg, Gaggenau-Michelbach, Katzenbusch ; 48°48′40″ N, 8°22′32″ E; elev. 348 m; 24 Jun.‒9 Jul. 2011; D. Doczkal leg.; Malaise trap; Quercus petraea forest; ZSM-DIP-42304-C09 .

Other characters

Male

BODY LENGTH. 2.3 mm.

HEAD. Eye bridge dorsally 8 ommatidia long. Scape and pedicel brighter than flagellum. Length of flagellum unknown, only 4 flagellomeres retained; neck of fourth flagellomere 0.9× as long as node ( Fig. 11F ). Palpus 4-segmented, longer than head height.

WING. As long as body. Length /width ratio 2.6.

TERMINALIA. Gonocoxal synsclerite slightly broader than long; ventral setae unusually small and sparse medially, larger and normally dense laterally; ventral emargination small, subtrapezoid, its basal margin membranous, sinuous, with fine setulae in two separate clusters; dorsoposterior portions only slightly protruding beyond ventroposterior portions; dorsal apodemes long and thin ( Fig. 11D ). Gonostylus slender, 3 × as long as high, on apical third slightly curved, pointed; apex with conspicuously dense microtrichia (causing darker coloration), sparse, with fine setulae, 4 short subapical bristles dorsally, and moderately large pectinate tooth ( Fig. 11A–B ). Ventral parameres present as a pair of small, slightly bent, pointed appendages situated in apical third of aedeagal apodeme. Aedeagal apodeme twice as long as posterior parameres; its apex protrudes slightly beyond ventral parameres; basal half portion weakly sclerotized, conversely T-shaped; point of junction with accessory gland ducts marked by a pair of parallel, elongate sclerotizations whose appearance is similar to that of the ventral parameres ( Fig. 11E ).
