Checklist of decapod crustaceans from the coast of the Sao Paulo state (Brazil) supported by integrative molecular and morphological data: IV. Infraorder Anomura: Superfamilies Chirostyloidea, Galatheoidea, Hippoidea and Paguroidea

This checklist is the fourth contribution resulting from a long-term multidisciplinary project which combined morphological analyses and molecular techniques (mitochondrial DNA markers) for accurate identification of marine and coastal decapod crustaceans of Sao Paulo State (Brazil). We provide a list of 63 species of the following 11 families of 4 superfamilies of Anomura: Albuneidae (4 spp.), Blepharipodidae (1 sp.), Chirostylidae (1 sp.), Diogenidae (18 spp.), Hippidae (1 sp.), Munididae (8 spp.), Munidopsidae (1 sp.), Paguridae (13 spp.), Parapaguridae (2 spp.), Porcellanidae (13 spp.), and Pylochelidae (1 sp.). Seven species previously reported from the region were neither collected nor found in museum collections during our study, including one (Sympagurus dimorphus) that we suggest to be removed from Sao Paulo coast fauna lists. We generated new sequences of cytochrome oxidase subunit I (barcode region) and 16S genes of 44 species. This anomuran inventory may serve as guideline for future studies on taxonomy, conservation, population genetics, biogeography, and phylogenetics, which might flag species that deserve further investigations and concerns.

Automated summary

This study presents the fourth contribution of a long-term multidisciplinary project to accurately identify marine and coastal decapod crustaceans of Sao Paulo State, Brazil. A list of 63 species from 11 families of 4 superfamilies of Anomura is provided, along with new sequences of genetic markers for 44 species, serving as a guideline for future research on taxonomy, conservation, population genetics, biogeography, and phylogenetics.
