New taxa and new records of Winnertziinae and Porricondylinae (Diptera: Cecidomyiidae) from Germany Author Jaschhof, Mathias 8B4B11B4-7C33-41AC-A042-AA9903CDC4B1 Station Linné, Ölands Skogsby 161, 38693 Färjestaden, Sweden. mjaschhof@yahoo.de text European Journal of Taxonomy 2024 2024-09-05 953 1 134 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/download/2649/12235 journal article 10.5852/ejt.2024.953.2649 2118-9773 13749629 8F69D11D-3C9A-4468-A354-7D2F7A84DAEB Parepidosis lobata sp. nov. urn:lsid:zoobank.org:act: 1EE8B962-1C56-4661-A346-3F8C41D39A37 Fig. 21 Diagnosis Morphology The male of P. lobata sp. nov. is characterized by the gonostylus whose thick basal portion extends apicodorsally into an elongate-subtriangular process (↓ 1 , Fig. 21A ), and by the H-shaped tegmen whose lateral pillars are markedly bent dorsad beyond the cross connection (↓ 2 , Fig. 21A ). Larvae and females of the new species are unknown. DNA barcode CO1 sequences (642‒652bp) were obtained of four paratype specimens detailed below and allocated to three different BINs: BOLD:ADW4641 (specimen ZSM-DIP-42305-E05), BOLD:AEO7433 (ZSM-DIP-42306-A08), and BOLD:AEE7552 (ZSM-DIP-42306-G02 and ZSM-DIP-42306-G07). Morphological evidence in support of the genetic clustering was not found (see the remarks below). Search on BOLD’s BIN Database retrieved a further match for BIN BOLD:AEE7552, as Cecidomyiidae sp. from Bavaria , Germany (accessed 27 Aug. 2023 ). Etymology The Latin adjective ‘ lobata ’, for ‘lobate’, refers to the peculiar structure of the gonostylus.

Other characters Male BODY LENGTH . 1.5‒2.0 mm. HEAD . Eye bridge dorsally 3‒4 ommatidia long. Antenna markedly longer than body; scape and pedicel brighter than flagellum; circumfila present on flagellomeres 1‒13; neck of fourth flagellomere 2.0‒2.2 × as long as node ( Fig. 21B ). Palpus 4-segmented, slightly longer than head height. THORAX . Scutal setae sparse. Anepisternal setae 0‒4. WING . Longer than body. Length / width ratio 2.9‒3.2. Fig. 21. Parepidosis lobata sp. nov. A . Holotype, ♂, terminalia, ventral view (ZSM- DIP-42306-G09). B . Holotype, ♂, fourth flagellomere, lateral view. C . Paratype, ♂, parameres, ventral view, variation (ZSM-DIP-42306-G02). Scale lines: 0.05 mm. The numbered arrows indicate diagnostic characters (see text). LEGS . Claws with large tooth basally. Empodia ⅓ as long as claws. TERMINALIA ( Fig. 21A ). Gonocoxal synsclerite: ventral emargination deeply U-shaped, reinforced basally; setose portion below emargination very short; anterior margin membranous, of varying outline. Gonostylus: medial bulge subglobular, with 2‒3 ordinary setae and 1 long bristle below pectinate tooth. Aedeagal apodeme markedly longer than gonocoxae, moderately sclerotized; both base and apex broadened, apical broadening subrectangular, slightly sclerotized; ducts of accessory glands evident (not illustrated). Remarks The new species exhibits morphological variation to the same, normal extent as found in other Parepidosis ( Jaschhof & Jaschhof 2013 ) . The confusing thing about P. lobata sp. nov. is that, in slide-mounted specimens examined ventrally, the length of the tegminal processes varies depending on how strongly the tegminal apex is bent dorsally under the pressure of the cover slip ( Fig. 21A, C ).
