Reinstatement and Rediagnosis of Catapaguroides setosus and Description of a Second Hawaiian Species of the Genus (Decapoda: Anomura: Paguridea: Paguridae)

Abstract

A species of the hermit crab genus Catapaguroides recently discovered in a sand-dwelling Halimeda community on the island of Maui, Hawaiian Islands, prompted a reexamination of the holotype of Catapaguroides setosus (Edmondson, 1951), described from off the south coast of O'ahu. The latter species, currently considered a junior subjective synonym of Catapaguroides fragilis (Melin), is herein adjudged neither synonymous with C. fragilis nor conspecific with the second Hawaiian species. Catapaguroides setosus is reinstated with full specific rank, rediagnosed, and illustrated. The second species, Catapaguroides hooveri McLaughlin & Pittman, n. sp., is described and illustrated.
