New taxa and new records of Winnertziinae and Porricondylinae (Diptera: Cecidomyiidae) from Germany Jaschhof, Mathias European Journal of Taxonomy 2024 2024-09-05 953 1 134 Jaschhof 2024 [573,916,913,940] Insecta Cecidomyiidae Schistoneurus Animalia Diptera 107 108 Arthropoda species 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 mmin  S. subimpressusversus 2.2 mmin  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 holotypespecimen 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.    Type material    Holotype  GERMANY• ♂; Bavaria, Lower Franconia, Rimpar; 49°87′32″ N, 9°93′24″ E; elev.  272 m;  12 Jul. 2019; LandKlifand J.
