Primary homonym of Tenthredo fulvipes Scopoli, 1763 [= Aglaostigma (Astochus) fulvipes (Scopoli, 1763)]. Lectotype ♀ (designated by Vikberg 2006 ) in MZLU, examined. Type locality: Sweden. Nematus aphantoneurus Foerster , 1854: 323-325. Lectotype ♀ (DEI-GISHym31561; designated by Vikberg 2006 ) in ZSM, examined. Type locality: Aachen, North Rhine-Westphalia, Germany. Cryptocampus distinctus Costa, 1882: 198. Syntype(s) ♀ possibly in MZUN, not examined. Type locality: Oschiri, Sardinia, Italy. Note. Identity of the type(s) is uncertain, could be P. luteipes . Pristiphora pygmaea Lindqvist, 1964: 130. Holotype ♀ in MZH, examined. Type locality: Helsinki, Finland. Similar species. The most similar species is P. luteipes , from which it cannot be always distinguished morphologically. Vikberg (2006) mentions that the mesepisternum is completely smooth unlike in P. luteipes , which should show at least slightly coriaceous sculpture (Fig. 19 and Fig. 6a in Vikberg 2006 ). However, P. luteipes can also have a completely smooth mesepisternum, especially in southern European specimens. See Vikberg (2006) for additional minor characters for separating these species. Males are unknown. Genetic data. Based on a COI barcode sequence of one confidently identified specimen (reared ex ovo from Lathyrus pratensis ) from Finland (DEI-GISHym80037), it belongs to the same BIN cluster (BOLD:AAG3568) as P. bifida , P. confusa , P. luteipes , P. opaca , P. pusilla , P. staudingeri , and P. subopaca (Fig. 1 ). The nearest neighbour (BOLD:AAQ2302, P. armata and P. leucopus ) is 2.76% different. Amplification of TPI of the specimen DEI-GISHym80037 failed, but we were able to obtain this nuclear sequence for one specimen from Estonia (DEI-GISHym31258) which had a nearly identical COI barcode (one nucleotide difference). Because the mesepisternum of this female was completely smooth, we identified it as P. aphantoneura . If this is correct, then TPI sequence data would be consistent in separating P. aphantoneura from closely related P. luteipes feeding on Salix (Fig. 2 ), although more specimens and some other nuclear sequences should be sampled to confirm this. Host plants. Lathyrus pratensis L. ( Vikberg 2006 ). Distribution and material examined. Palaearctic. Specimens studied are from Estonia , Finland , and Germany .
