Winnertzia subdentata Jaschhof, 2024, sp. nov.

Winnertzia subdentata sp. nov. urn:lsid:zoobank.org:act: B2ADA399-FDB9-470F-891F-4519B673891B Fig. 7 Differential diagnosis Morphology Winnertzia subdentata sp. nov. closely resembles W. dentata Jaschhof & Jaschhof, 2020, a species known exclusively from southeastern Sweden (Jaschhof & Jaschhof 2020b). Differences in the male morphology of both species are as follows (females and larvae are unknown). The most important distinction is that the gonostylar apex of W. subdentata is convex (rounded) and equipped with 2, perhaps even 3 thick, closely spaced spines that upon first sight might appear as one small, solid tooth (↓ 1, Fig. 7A), whereas the gonostylus of W. dentata is distinctly blunt-ended and indeed equipped with a single solid tooth that is two or three times as large as an ordinary spine (Jaschhof & Jaschhof 2020b: fig. 43). Less striking is that the basolateral apophysis of the gonostylus is smaller in W. subdentata compared with W. dentata (↓ 2). Both species are nearly identical in non-terminalia characters. The number of flagellomeres in W. subdentata is either 11 (paratype, body length 1.7 mm) or 12 (holotype, body length 2.5 mm), and in both specimens translucent sensilla are present on flagellomeres 1‒10, whereas the single specimen known of W. dentata has 11 flagellomeres, with the apical flagellomere long and subdivided, and translucent sensilla on flagellomeres 1‒9 (Jaschhof & Jaschhof 2020b). DNA barcode CO1 sequences (641‒652bp) of the type specimens are available in BIN BOLD:ACG4326. A search in BOLDʼs BIN Database retrieved a further match for this BIN, as Cecidomyiidae sp. from Bavaria, Germany (accessed 26 Aug. 2023). Etymology The name ‘ subdentata ’, which in a broader sense means ‘beside dentata ’, refers to the close resemblance of the two species.
