Abstract

During an extensive sampling off the east peninsular Indian coast, three species of leucosiid brachyuran genus Arcania were encountered. Of these, Arcania gracilis Henderson, 1893 is reported about 125 years after it was originally found at the same expanse. A. erinacea (Fabricius, 1787) is a new record to this region. A. septemspinosa (Fabricius, 1787) is the third which co-inhabited. These are briefly described with taxonomic characteristics and distributional details. Information on the numerical abundance, depth, ambient salinity, dissolved oxygen, sediment, organic content are also presented. The present finding demonstrates the species resilience to environmental perturbations over the years.
