Revision of the American species of the genus Prionus Geoffroy, 1762 (Coleoptera, Cerambycidae, Prioninae, Prionini) Author Santos-Silva, Antonio Author Nearns, Eugenio H. Author Swift, Ian P. text Zootaxa 2016 4134 1 1 103 journal article 10.11646/zootaxa.4134.1.1 a157eae0-8cb8-4b9a-8ce5-dd7ff7913ba3 1175-5326 399754 92AC0E20-F532-4D21-AE1F-4B056327212F On Prionus ( Prionellus ) Casey, 1924 Prionellus Casey, 1924 is a junior homonym of Prionellus Kieffer, 1895 ( Diptera , Cecidomyiidae ). Thus, although we agree that Prionus ( Prionellus ) is a synonym of Prionus , as indicated by Linsley (1962) , the name must be replaced. Linsley (1962) designated Prionus pocularis Dalman, 1817 as the type species of Prionus ( Prionellus ) , and considered the genus as a synonym of Prionus ( Prionus ) . Linsley (1962) gave no explanation as to the reason for the synonymy. The designation of Prionus pocularis as the type species of Prionus ( Prionellus ) was a mistake. Prionus pocularis was not included in Prionus ( Prionellus ) by Casey (1924) : it was included in Prionus ( Prionus ) . Thus, it cannot be the type species of the subgenus (ICZN, 1999: Article 67.2). To solve these nomenclatural issues, we designate: 1. Hypoprionus as a replacement name for Prionellus Casey, 1924 , masculine gender. Etymology: Hypo , a prefix from Greek, meaning “sub”, “under”; relative to the “small” size of the species commented on by Casey (1924) in the description of Prionellus . 2. We choose as the type species of Prionus ( Prionellus ) , and consequently for Hypoprionus nom. nov. , Cerambyx laticollis Drury, 1773 , the first species listed by Casey (1924) in his subgenus Prionus ( Prionellus ) .
