On Prionus ( Prionellus) Casey, 1924

Prionellus Casey, 1924 is a junior homonym of Prionellus Kieffer, 1895 ( Diptera View in CoL , Cecidomyiidae View in CoL ). Thus, although we agree that Prionus ( Prionellus) View in CoL is a synonym of Prionus View in CoL , as indicated by Linsley (1962), the name must be replaced.

Linsley (1962) designated Prionus pocularis Dalman, 1817 View in CoL as the type species of Prionus ( Prionellus) View in CoL , 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 View in CoL as the type species of Prionus ( Prionellus) View in CoL 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) .
