Curculio pilosus Fabricius, 1781: 110

Caldara, Roberto, Košt, Michael, ál & Morris, Michael G., 2013, On the complex nomenclatural situation of two common Palaearctic weevils: Dorytomus rufatus Bedel, 1888 and Orchestes pilosus Fabricius, 1781 (Coleoptera: Curculionidae), Journal of Natural History 47 (13 - 14), pp. 1009-1017: 1013-1014

B. Orchestes pilosus ( Fabricius, 1781)   Edit

Curculio pilosus Fabricius, 1781: 110   Edit

Fabricius (1781) described Curculio pilosus   Edit on specimens from Anglia (i.e. England). Subsequently this species was placed by authors in the genus Rhynchaenus Clairville, 1798   Edit and then in the genus Orchestes Illiger, 1798   Edit . In Fabricius’s collection there is one pinned female specimen with a historical label “pilosus” corresponding to the taxon as usually considered. We made a genitalia dissection (spermatheca) and designated this specimen as the lectotype of Curculio pilosus Fabricius   Edit and labelled it as follows “ LECTOTYPUS Curculio pilosus Fabricius, M.   Edit Košt’ál des. 2012 [red printed] / Orchestes pilosus (Fabricius) Michael   Edit Košt’ál det. 2012”.

Although there has been apparently unequivocal agreement on the taxonomy of the species, two of the three taxa usually quoted as synonyms of Curculio pilosus   Edit – Curculio segetis Linnaeus, 1758   Edit and Curculio saltatorsegetis DeGeer, 1775   Edit – appear to have priority.

1. Curculio segetis Linnaeus, 1758   Edit

Curculio segetis Linnaeus, 1758: 381   Edit .

Linnaeus (1758) described this taxon on specimens from Sweden, which are not now preserved in his collection. Therefore, following the authors’ general opinion on this taxon, we decided to designate a specimen of Orchestes pilosus   Edit as the neotype of Curculio segetis Linnaeus. It   Edit is a male collected in Sweden labelled “Sk Hässleholm. 12.7.1953 3152 G.Israelson / pilosus / NEOTYPUS Curculio segetis Linnaeus Caldara   Edit , Košt’ál & Morris des. 2012 [red printed] / Orchestes pilosus (Fabricius) Michael   Edit Košt’ál det. 2012”. The specimen is 3.17 mm long (rostrum excluded), perfectly preserved with dissected genitalia. It is deposited in the Museum of Zoology, University of Lund.

2. Curculio saltatorsegetis DeGeer, 1775   Edit

Curculio saltatorsegetis DeGeer, 1775: 264   Edit .

DeGeer (1775) described this taxon, probably on specimens from Sweden, as “ Curculio   Edit (saltator Segetis)”, using two words for a specific name as in many others of his species, quoting Curculio segetis Linnaeus   Edit as its synonym. These specimens were not found in his collection at the Naturhistoriska Riksmuseet Stockholm. Therefore, following the authors’ general opinion on this taxon, we decided to designate a specimen of Orchestes pilosus   Edit as the neotype of Curculio saltatorsegetis DeGeer. It   Edit is a male collected in Sweden labelled “ Suecia Småland, Fagerhyltan RN 6254055 1499155 01 09 2002 CF3004 Leg: C. Fägerström / Orchestes pilosus   Edit Curculionidae ( Fabricius, 1781) Det   Edit : C. Fägerström / NEOTYPUS Curculio saltatorsegetis DeGeer Caldara   Edit , Košt’ál & Morris des. 2012 [red printed] / Orchestes pilosus (Fabricius) Michael   Edit Košt’ál det. 2012”. The specimen is 3.27 mm long (rostrum excluded), perfectly preserved with dissected genitalia. A small part of the apex of the aedeagus is chipped. The specimen is deposited in the Museum of Zoology, University of Lund.

3. Curculio ilicis Fabricius, 1787   Edit

Curculio ilicis Fabricius, 1787: 110   Edit .

In Fabricius’s collection under the label with the name ilicis   Edit there are three specimens, all belonging to Orchestes pilosus   Edit . We dissected two of them for genitalia and designated the male specimen as the lectotype of Curculio ilicis   Edit , which is now labelled “ LECTOTYPUS Curculio ilicis Fabricius, M.   Edit Košt’ál des. 2012 [red printed] / Orchestes pilosus (Fabricius) Michael   Edit Košt’ál det. 2012”. The other two specimens were designated as paralectotypes (both labelled as the lectotype except for “ Paralectotypus ”).

In summary, according to what reported at the points 1–3 of Section B and to Article 29 of ICZN (1999), the junior name pilosus ( Fabricius, 1781)   Edit can be maintained since Curculio segetis   Edit and Curculio saltatorsegetis   Edit meet the requirements of Article 23.9.1.1 and Orchestes pilosus   Edit meets those of Article 23.9.1.2 of ICZN (1999) by quoting the following references: Abbazzi and Maggini 2009; Abbazzi and Osella 1992; Abbazzi et al. 1995; Alonso-Zarazaga 2002; Angelini, 1984, 1991; Benedikt et al. 2010; Bercio and Folwaczny 1979; Braunert 2009; Colonnelli 2003; Delbol 2008; Endrödi 1970; Germann 2010; Holecová and Zach 1996; Lohse 1983b; Mazur 2002; Morris 2002, 2003; Pelletier 2005; Podlussány 1998; Rheinheimer and Hassler 2010; Silfverberg 1979; Telnov 2004; Tempère and Péricart 1989; Wanat and Mokrzycki 2005. Therefore we propose the acceptance of the following synonymies:

Orchestes pilosus ( Fabricius, 1781)   Edit nomen protectum

= Curculio segetis Linnaeus, 1758   Edit nomen oblitum

= Curculio saltatorsegetis DeGeer, 1775   Edit nomen oblitum

= Curculio ilicis Fabricius, 1787   Edit
