Abstract

Abstract The present study provided information extending the known geographical distribution of the calappid crab Cryptosoma balguerii (Desbonne in Desbonne and Schramm, 1867). We provide new data that extends the range of this species in the western Atlantic farther to the south in the Brazilian region, State of Sao Paulo and check its identification by molecular tools within Cryptosoma and other calappid crabs. New records of marine species provide a baseline for a better understanding of the biodiversity of ecological provinces. This work is an example of the importance of an exhaustive and continuous investigation on the biodiversity of subtidal rocky bottoms.

Highlights

Calappidae De Haan, 1833 is a group of marine crabs with distribution extending throughout the tropical and subtropical regions of the world (Bellwood, 1996)
All western Atlantic records of Cycloes bairdii were attributed to Cryptosoma balguerii (Galil and Clark, 1996)
During an exhaustive period of sampling along the coast of São Paulo state as part of a long-term project on marine biodiversity (Mantelatto et al, 2018), a single adult calappid crab was collected in Ubatuba region in October 2019 by using a fishing boat with two double-rig nets, at 26 m depth

Summary

Introduction

Calappidae De Haan, 1833 is a group of marine crabs with distribution extending throughout the tropical and subtropical regions of the world (Bellwood, 1996). Cryptosoma has four recognized species: Cr. bairdii (Stimpson, 1860), Cr. balguerii (Desbonne in Desbonne and Schramm, 1867), Cr. cristatum Brullé, 1937, and Cr. garthi Galil and Clark, 1996 (Galil and Clark, 1996; Ng et al, 2008) and Cycloes is composed by Cy. granulosa De Haan, 1837 and Cy. marisrubri Galil and Clark, 1996 (Galil and Clark, 1996; Ng et al, 2008) After these reviews, all western Atlantic records of Cycloes bairdii were attributed to Cryptosoma balguerii (Galil and Clark, 1996). We provide new data that extends the geographical distribution of Cryptosoma balguerii to the coast of the state of São Paulo (Brazil)
