Description of two new species and phylogenetic reassessment ofPerelleschusO’Brien & Wibmer, 1986 (Coleoptera: Curculionidae), with a complete taxonomic concept history ofPerelleschussec. Franz & Cardona-Duque, 2013

The weevil genus Perelleschus O’Brien & Wibmer, 1986, is revised; including the description of P. salpinflexus Cardona-Duque & Franz sp. nov. sec. Franz & Cardona-Duque (2013) from Colombia and P. spinothylax Cardona-Duque & Franz sp. nov. sec. Franz & Cardona-Duque (2013) from Colombia and Venezuela. This study furthermore demonstrates the feasibility and utility of the taxonomic concept approach as laid out in Franz & Peet (2009). In particular, we establish and consistently practice a convention where (1) the taxonomic name sec. author annotation is used in all instances where a specific meaning of a name is intended; (2) just the taxonomic name is used to refer to the cumulative nomenclatural and taxonomic legacy associated with that name; and (3) the term [non-focal] is added to a taxonomic name to signal that specifying or redefining its meaning is outside of the scope of this study. We reproduce six classifications and 54 constituent taxonomic concepts that represent a complete taxonomic history of...
