Pristiphora aphantoneura ( Foerster, 1854) Fig. 195

Tenthredo fulvipes Fallén, 1808: 113. Primary homonym of Tenthredo fulvipes Scopoli, 1763( Scopoli 1763) [= Aglaostigma (Astochus) fulvipes (Scopoli, 1763)]. Lectotype ♀ (designated by Vikberg 2006) in MZLU, examined. Type locality: Sweden.

Nematus aphantoneurus Förster, 1854b: 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. Synonymised with P. fulvipes by Costa (1894). 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. Synonymised with P. aphantoneura by Vikberg (2006).

Similar species.

The most similar species is P. luteipes , from which it cannot be always distinguished morphologically. Vikberg (2006) mentioned that the mesepisternum is completely smooth unlike in P. luteipes , which should show at least slightly coriaceous sculpture (Fig. 45 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), P. aphantoneura 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 Prous et al. 2016). Maximum distance within the BIN is 3.33% and minimum between species distance is 0.00%. The nearest neighbour to BOLD:AAG3568, diverging by minimum of 2.76%, is BOLD:AAQ2302 ( P. armata and P. leucopus ). Based on nuclear data (if the specimen DEI-GISHym31258 is correctly identified), the nearest neighbour is 0.2% different ( P. luteipes , both genes combined).
