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 Schistoneurus subimpressus sp. nov. urn:lsid:zoobank.org:act: 88CE3BC6-3B59-4073-B8B6-A2A365D0AF4B Fig. 30 Differential diagnosis Morphology The single male described here as S. subimpressus sp. nov. differs from S. paraimpressus sp. nov. in having shorter flagellomeral necks (the neck-to-node ratio in the fourth flagellomere is 1.5 in S. subimpressus ( Fig. 30C ) versus 2.0 in S. paraimpressus ( Fig. 29C )) and in the construction of the gonostylus, of which the particulars are as follows. The gonostylus of S. subimpressus ( Fig. 30B ) is more compact; the thick black spines cover a markedly smaller area apically and apicomedially; the inside is less sharply separated from the outside (note the sharp longitudinal edge with black spines in S. paraimpressus , Fig. 29B ); and the ventral protrusion bears not just ordinary setae but a small cluster of black spines. The two species might also differ in body length ( 1.7 mm in S. subimpressus versus 2.2 mm in S. paraimpressus ), but this difference, derived from a small specimen sample, should be taken with caution considering the size variation described for S. impressus (1.7‒2.0 mm, Jaschhof & Jaschhof 2013 ). Larvae and females of the new species are unknown. DNA barcode The CO1 sequence (653bp) of the holotype specimen is available in BIN BOLD:AEO6709. Search on BOLDʼs BIN Database retrieved no further result for this BIN (accessed 27 Aug. 2023 ). Etymology The name ‒ the Latin prefix ‘ sub -’ means, in a broad sense, ‘beside’ ‒ is an allusion to the morphological similarity of this species to S. impressus .
