The type material of the species of Laparocerus Schönherr, 1834 (Coleoptera, Curculionidae, Entiminae) Author Machado, Antonio text Journal of Natural History 2006 2006-12-21 40 35 - 37 2001 2055 http://dx.doi.org/10.1080/00222930601046659 journal article 10.1080/00222930601046659 1464-5262 5232123 Laparocerus piceus Boheman, 1834 ** Laparocerus piceus Boheman in Schönherr 1834 , p 531 . Type locality. Island of Madeira . Holotype : 1♀ much rubbed [ Lusitania / Falderman ]. NR ( Coll. Schönherr ), Stockholm . Remarks. The species was described by Boheman based on a single female labelled as from Lusitania (5 Portugal ); however, Gyllenhall is often cited as author. I have seen specimens of L. azoricus Drouet labelled as L. piceus in several collections (Coll. Stierlin, Osella, Poncy, etc.). Furthermore, Marseul (1872 , p 548) placed the species with a question-mark as synonym of L. vespertinus ( Wollaston, 1854 ) and it is recorded identically in Winkler (1932 , p 1448), even though L. piceus Boheman, 1834 would have priority over L. vespertinus ( Wollaston, 1854 ) , as posteriorly recognized by Schmitz (1898 , p 154) in his list of Madeiran coleoptera. It has been registered in several catalogues ( Jacquelin du Val 1855 ; Lacordaire 1863 ; Lona 1938 , etc.) as from Portugal , and only Lundblad (1958 , p 485) assumes that the locality label ‘‘Lusitania’’ must be an error as in the case of L. morio , equally described by Boheman on a specimen provided by Falderman. Consequently, I assume the island of Madeira as the locality where the type really originated. The holotype of L. piceus is kept in Stockholm. It is a rubbed female specimen that resembles L. noctivagans ( Wollaston, 1854 ) , but could equally be assigned to L. lauripotens ( Wollaston, 1854 ) . Females of this group of Laparocerus ( L. vespertinus , included) are not always easy to separate. Therefore I propose to consider L. piceus , a nomen dubium .
