Rhamphus oxyacanthae ( Marsham, 1802)

Curculio oxyacanthae Marsham, 1802: 263 .

This taxon was described from specimens from Britain, without a more precise locality, collected on Crataegus oxyacantha L. (presumably C. monogyna Jacquin ). Recently, M. G. Morris (pers. comm.) informed us that there are no specimens of the type series of Curculio oxyacanthae in Marsham’s material at BMNH. Therefore, following the authors’ general opinion on this taxon, with the expressed purpose to clarifying its taxonomic status, and under the qualifying conditions enunciated in Article 75.3 of the ICZN (1999), we decided to designate a neotype of Curculio oxyacanthae Marsham, 1802 . It is a female labelled “ England, Suffolk TL 7086, Lakenheath Station, 23.06.2020., off Crataegus, lgt. H. Mendel, DNA voucher 5953 IT/ NEOTYPE Curculio oxyacanthae Marsham, 1802 , Caldara & Toševski des. 2021 [red printed]/ Rhamphus oxyacanthae ( Marsham, 1802) Caldara & Toševski det. 2021 mt COI acc. N. MZ404333 ”. The specimen ( Fig. 3A ) is 1.7 mm long (rostrum excluded), well preserved with dissected genitalia. Its online acc. Number is MZ404333 (NCBI database). The neotype is deposited at the BMNH. In accordance with the Article 76.3 of the ICZN (1999) the place of origin of the neotype becomes the type locality of this taxon.
