ABSTRACT

Apart from traditional characters, other data have been used for taxonomy, like color patt erns. Based on the diff erent colors (green and orange) observed for some Calcinus tibicen (Herbst, 1761) specimens, we evaluated the genetic distance for cytochrome oxidase subunit I mitochondrial gene of individuals collected in Pernambuco (northern Brazil) and in São Paulo (southeast Brazil). We found low genetic variation (0.2–1.1%), and no evidence of isolation on our molecular tree based on genetic distance. We suggest high levels of gene fl ow between specimens with diff erent color patt erns, which are polymorphisms and might be related to the kind of nutrition as well diff erent ecological and evolutionary predation characteristics. keY woRds Anomura, COI gene, coloration, Diogenidae, polymorphism. sHoRt commUnIcAtIon This article is part of the special series offered by the Brazilian Crustacean Society in honor to Ludwig Buckup in recognition of his dedication and contributions to the development of Carcinology CORRESPONDING AUTHOR Fernando Luis Mantelatto mantel@usp.br SUBMITTED 28 August 2017 ACCEPTED 22 November 2017 PUBLISHED 26 March 2018 Guest Editors Alessandra A. de Pádua Bueno and Sandro Santos DOI 10.1590/2358-2936e2018008 orcid.org/0000-0002-3092-9588
