Description Paphia malabarica Chemnitz, 1782 is an economically important species of Venerid clam in Indian
waters. The fishery of P. malabarica from Ashtamudi estuary, Kollam, Kerala has been certified by
marine stewardship council as sustainable and the fishery is now managed by a set of fishery
management plans. The name P. malabarica is invalid now as it has been synonymized as Paphia
(Protapes) gallus (Gmelin, 1791) in subsequent taxonomic investigations. We examined the taxonomic
status of P. malabarica using morphological and molecular methods. Morphological characteristics of
the shell mainly, shell structure, size and internal features were compared between P. gallus and P.
malabarica indicating significant differences in morphology. Molecular investigations were carried out
by amplifying and sequencing mitochondrial Cytochrome C Oxidase 1 (COI) and 16SrRNA sequences
of P. malabarica collected from Ashtamudi (Kollam), Dharmadam, Kannur (3 locations in Kerala),
Goa, Maharashtra, Gujarat and Tuticorin in order to clear the taxonomic ambiguity and validate the
synonymy. Sequences of P. malabarica were compared with sequences of P. gallus and other Paphia
species. Substantial genetic divergence was detected between P. malabarica and P. gallus with a K2P
genetic distance value of 28.9% and distinct clustering in phylogenetic tree demonstrating that P.
malabarica is well diverged from P. gallus. We suggest retaining the name P. malabarica considering
that the synonymy with P. gallus is invalid.
