First record of three species of leucosiid crabs (Crustacea: Brachyura: Leucosiidae) Arcania heptacantha (De Man, 1907), Arcania septemspinosa (Fabricius, 1787) and Ixa cylindrus (Fabricius, 1777) from Bangladesh

Abstract

This study reports the first occurrence of three leucosiid crabs, Arcania heptacantha De Man, 1907, Arcania septemspinosa (Fabricius, 1787), and Ixa cylindrus (Fabricius, 1793), from Saint Martin’s Island, Bangladesh. These species were identified using taxonomic accounts based on both morphology and DNA barcoding. The nucleotide sequences of the cytochrome c oxidase subunit I gene (COI) barcode region of all of three species were also identified and submitted to GenBank for the first time. These records update the country’s total number of crab species as well as extend the geographic range of these species to the northeastern Bay of Bengal.
