Winnertzia macrodens Jaschhof, 2024, sp. nov.

Winnertzia macrodens sp. nov. urn:lsid:zoobank.org:act: B10E97E1-8F8F-461B-A391-680780A28B57 Fig. 6 Diagnosis Morphology A further new species of the W. globifera group (Jaschhof & Jaschhof 2020b), W. macrodens sp. nov. is distinguished by several male terminalia characters occurring in combination (Fig. 6A). The gonostylus, which is unusually strongly narrowed subbasally, bears a slightly obliquely aligned pectinate tooth of considerable size (↓ 1). The posterior margin of the ninth tergite has a wide shallow emargination (↓ 2). The aedeagal apodeme has an abrupt broadening beyond the solid basal portion and a long, strongly narrowed apical portion (↓ 3). Larvae and females of W. macrodens are unknown. DNA barcode CO1 sequences (651‒652bp) were obtained of the type specimens specified below and allocated to BIN BOLD:ADW3425. A search in BOLDʼs BIN Database retrieved no further result for this BIN (accessed 26 Aug. 2023). Etymology The specific epithet ‘ macrodens ’, a noun in apposition, marks the conspicuously large gonostylar tooth found in this species. Type material Holotype GERMANY • ♂; Baden-Württemberg, Malsch, Luderbusch; 48°91′31″ N, 8°33′25″ E; elev. 117 m; 31 May‒7 Jun. 2020; D. Doczkal and K. Grabow leg.; Malaise trap; south-facing hill slope; BOLD GBDTA10466-21; ZSM-DIP-42309-B04.

Eye bridge dorsally 1‒2 ommatidia long. Antenna markedly shorter than body; scape and pedicel of same size, both concolorous with flagellum; 12 flagellomeres, translucent sensilla on flagellomeres 1‒8. Fourth flagellomere with neck 0.8× length of node, node 1.8× as long as broad; sensory hairs fairly sparse, translucent sensilla multiform, either straight, variously U-shaped or irregularly branched (Fig. 6B). Palpus shorter than head height, with 4 setae-bearing segments, apical segment longest of all. Labella small. THORAX. Pronotal setae 5‒6. Anepimeral setae absent. Mediotergal lateral microtrichia markedly enlarged. Parascutellar area bright, sharply contoured. WING. Shorter than body. Length / width ratio 2.6. Costal cell slightly reinforced. M 4 long, faint, almost straight; CuA slightly bent apically, both veins extending to wing margin. LEGS. With pointed scales. Basitarsal spines absent. Fore tibia 1.2× length of T 2. Acropods: claws slightly bent, toothless; empodia vestigial. ABDOMEN. Pleural membrane devoid of vestiture. TERMINALIA (Fig. 6A). Ninth tergite one half of gonopodal length, setae confined to posterior half; anterior margin straight, indistinct. Gonocoxal synsclerite slightly broader than long; a large portion ventroanteriorly glabrous; ventral emargination U-shaped, sharply contoured, without membranous area basally; ventroanterior margin distinct, broadly rounded; dorsoposterior portions narrowly rounded, slightly protruding beyond ventroposterior portions; dorsal apodemes thin, moderately long, widely separated from each other. Gonostylus 2.5× as long as broad; basolateral apophysis small, slightly angulated. Tegmen subtriangular, sharply contoured; flaps with distinct margins; parameral apodemes small. Solid basal portion of aedeagal apodeme short. Aedeagal bulge with closely spaced rows of tiny spikes.
