Proposal to replace the illegitimate genus name Bryantella Wolin et al. 2004VP with the genus name Marvinbryantia gen. nov. and to replace the illegitimate combination Bryantella formatexigens Wolin et al. 2004VP with Marvinbryantia formatexigens comb. nov.

The prokaryote generic name Bryantella Wolin et al. 2004(VP) is illegitimate because it is a later homonym of Bryantella Chickering, 1946 (Animalia, Arthropoda, Arachnida, Araneae, Salticidae, Dendryphantinae, Dendryphantini) and a later homonym of Bryantella Britton, 1957 (Animalia, Arthropoda, Scarabaeoidea, Scarabaeidae, Melolonthinae) [Principle 2, Rule 51b(4) of the Bacteriological Code (1990 Revision)]. Bryantella represents a genus of jumping spiders within the family Salticidae and a genus of melolonthine scarab beetles within the family Scarabaeidae. Therefore, a new genus name, Marvinbryantia gen. nov., is proposed for this taxon. As a result, a new combination, Marvinbryantia formatexigens comb. nov., is required for the type species to replace the illegitimate combination Bryantella formatexigens Wolin et al. 2004(VP).
