On the identity of European Baridini (Coleoptera, Curculionoidea) named before 1832

Abstract

Twenty-nine names of European weevils usually regarded as Baridini in the literature are checked. Neotypes are designated for Curculio coerulescens Scopoli, 1763 (emend.), C.

A taxonomic revision of Limnobaris Bedel in the strict sense (Coleoptera, Curculionidae, Baridinae), with particular emphasis on the species found in China

“…The name had been ignored in weevil systematics until Alonso-Zarazaga and Lyal (1999) used it to replace Centrinina Jekel, 1865, a junior homonym preoccupied in the sharks. However, Zygobaridina becomes paraphyletic to the more senior Leptoschoinina Lacordaire, 1865 when the exposure of the pygidium is disregarded ( Prena 2008 ). The matter is complicated further by species in Anacentrinus Buchanan, 1932 (currently synonymized with Apinocis Lea, 1927), which develop in grasses ( Barber 1927 , Böving 1927 , Buchanan 1932 , Wille 1934 , Bryson 1941 ) but also in sedges (J. Prena, unpubl.…”

“…Lectotype designated by Dieckmann (1991 : 307), female, collecting data unknown (MNKB). Synonymized with Limnobaris t-album by Gemminger and Harold (1871) and Prena (2008) , and with Limnobaris t-album atriplicis sensu Dieckmann by Dieckmann (1991) .…”

“…Holotype female, Sicily, Italy (NHRS). Synonymized with Limnobaris t-album by Gemminger and Harold (1871) but reinstated or overlooked by subsequent authors; synonymized with Limnobaris t-album atriplicis sensu Dieckmann by Dieckmann (1991) and with Limnobaris t-album by Prena (2008) .…”

“… Limnobaris t-album atriplicis sensu Dieckmann (1991) : misinterpretation of Curculio atriplicis Fabricius, 1777 (= Curculio laticollis Marsham, 1802; nomen protectum) introduced into the literature by invalid lectotype designation (see Prena 2008 ). …”

“…Dieckmann (1991) considered them as a subspecies because he recongized (1) a continuous northern distribution of the nominal form of Limnobaris t-album and (2) a relatively narrow transitional zone to the deviating southern form. Prena (2008) rejected the subspecies because the applied name was based on an invalid lectotype designation and the transitional zone corresponds closely with the winter isotherm indicating a possible environmental effect on the scale pattern. The issue needs to be readdressed with appropriate methods in a larger context, i.e.…”
