Introduction
The cumacean genus name Dayus Gerken, 2001 (Crustacea: Peracarida: Cumacea) is preoccupied by Dayus Mahmood, 1967 (Insecta: Hemiptera: Cicadellidae). The purpose of the present paper is to propose a replacement name.
The cumacean genus Dayus was established by Gerken (2001) with three species: Dayus pharocheradus, Dayus acanthus and Dayus makrokolosus from Australia. Dauys pharocheradus was designated as the type species. However, Dayus Gerken, 2001 is preoccupied by Dayus Mahmood, 1967, established for a typhlocybine leafhopper genus, with Dayus elongatus Mahmood, 1967 (from Singapore) as the type species (Insecta: Hemiptera: Cicadellidae). According to Article 60 of the International Code of Zoological Nomenclature (ICZN 1999), we propose the new replacement name Jennidayus nom. n. for Dayus Gerken, 2001. Accordingly, three new combinations are herein proposed for the species currently included in this genus: Jennidayus pharocheradus (Gerken, 2001), Jennidayus acanthus (Gerken, 2001) and Jennidayus makrokolosus (Gerken, 2001).
Etymology.
The genus name was meant to honor Jennifer Day of South Africa, for her work on South African Cumacea; gender masculine.
Distribution.
Australia.
Summary of nomenclatural changes
