Description Crenidens macracanthus was originally described in 1874 based on a single specimen collected
from Chennai (Madras), south-east coast of India. In 1875, the species was synonymized with
C. indicus without citing any valid reason. Since then, no taxonomic studies have been
attempted for the genus Crenidens, except in 2013 the species was resurrected from synonymy
and redescribed as a valid species based on the holotype and non-type specimen. In view of
the fact that C. macracanthus is a poorly known species, it is redescribed based on examination
of 30 additional specimens of 105.8–162.2mm SL, collected from Puri, Odisha,
north-east coast of India (Bay of Bengal) from 2017–2019, using morphological and molecular
examinations. Our study provides a detailed morphological description, first colour photographs
and phylogenetic analysis using COI barcodes of the species. The study has expanded
the range in several morpho-meristic characters in comparison with the type and non-type
specimens described earlier. The species in fresh condition can be easily distinguished from
its two congeners (C. crenidens and C. indicus) by the yellowish tip of the lower caudal-fin
lobe. Our study has also extended the distribution range of C. indicus (previously known
only from the north-eastern Arabian Sea) to the eastern Indian Ocean, based on examination
of a preserved specimen collected from Tuticorin, Tamil Nadu.
