The systematic status of Afropisa sanctaehelenae (Chace, 1966) (Decapoda, Brachyura, Majoidea, Epialtidae): morphological and molecular evidence

<i>Afropisasanctaehelenae</i> (Chace, 1966) was originally described from three specimens collected from Saint Helena Island, South Atlantic, and assigned to <i>Pisa</i> Leach, 1814. It is a poorly known species, and until now, no new records have been reported. Recently, this species was transferred to a new genus, <i>Afropisa</i> Muñoz, García-Raso, González, Lopes, dos Santos & Cuesta, 2023, based exclusively on morphology. Nearly 60 years on from the original description, another eight specimens of <i>A.sanctaehelenae</i> have been made available for further study and sequencing. Mitochondrial 16S rRNA and cytochrome c oxidase subunit I sequences confirm the assignment of this Chace species to <i>Afropisa</i>. Photographs of the male holotype and female paratype confirmed the presence of additional characters; consequently, the present work provides a redescription of this species.
