Diagnosis

Morphology

A typical Asynapta , this new species is distinguished from congeners in male terminalia structures, as follows ( Fig. 8A ). Of the gonostylus, the posterior margin is strongly convex (↓ 1) and the pectinate tooth of moderate size is located entirely apically, rendering it only vaguely visible ventrally. The ventral parameres form an X-shape whose posterior branches are serrate apically and interconnected by a thin, medially split membrane (↓ 2). Of the gonocoxal synsclerite, the pointed anterior margin is reinforced by strong sclerotization (↓ 3) and the broadly U-shaped ventral emargination is only vaguely delineated basally. Larvae and females of A. doczkali sp. nov. are unknown.

DNA barcode

The CO1 sequence (652bp) of the holotype specimen is available in BIN BOLD:AER0700. Search on BOLD’s BIN Database retrieved no further result for this BIN (accessed 26 Aug. 2023).

Etymology

The species is named to honor Dieter Doczkal, dipterologist at the Zoologische Staatssammlung München. The project GBOL III: Dark Taxa benefitted enormously from Dieterʼs talent as an exceptionally gifted collector of entomological specimens, including gall midges.

Type material

Holotype

GERMANY • ♂; Baden-Württemberg, Malsch, Luderbusch ; 48°91′44″ N, 8°33′24″ E; elev. 112 m; 26 Apr.‒3 May 2020; D. Doczkal and K. Grabow leg.; Mala44

Other characters

Male

BODY LENGTH. 2.3 mm.

HEAD. Eye bridge dorsally 8 ommatidia long. Scape and pedicel nearly concolorous with flagellum. 18 flagellomeres; neck of fourth flagellomere half as long as node ( Fig. 8B ). Palpus: only 3 segments retained, presumably 4-segmented and longer than head height.

THORAX. Metepisternal setae absent.

WING. Slightly shorter than body. Length /width ratio 2.2.

LEGS. Claws small, toothless. Empodia almost as long as claws.

TERMINALIA ( Fig. 8A ). Gonocoxal synsclerite broader than long; setulae on medial bridges with sockets only slightly enlarged; dorsoposterior portions only slightly protruding beyond ventroposterior portions. Gonostylus twice as long as high. Dorsal parameres (tegmen) subrectangular, slightly broader than long, margins sclerotized. Aedeagal apodeme about half as long as tegmen, moderately sclerotized, with arrow-shaped structure at apex indicating the junction of accessory gland ducts.
