... Catopra malabarica described by Guenther (1864) from Mundakkayam of Kerala is also a widely distributed species in south India. P. rubripinis (Britz et al. 2012), P. pentacantha (Plamoottil, 2014) and P. procerus (Plamoottil, 2017) are the Pristolepis species described recently from water bodies of India. The present fish described from Myanmar possesses characters of the genus Pristolepis but carries enough features to distinguish it from its congeners. ...
... Plamoottil & Abraham (2013) collected many specimens of Pristolepis malabarica from its type locality and resurrected it from its synonymy with P. marginata. A five anal spined Pristolepis namely P. pentacantha was also been discovered (Plamoottil, 2014(Plamoottil, , 2015) from near the type locality of P. marginata and P. malabarica.

A new Pristolepis species from Myanmar is described and scientifically named. It differs from its congeners in having XIII dorsal spines, 15 dorsal soft rays, 15-16 pectoral fin rays, 5-6 scales between lateral line and dorsal fin, 12 ½ scales between lateral line and ventral fin and in possessing a distinct brownish blotch below pectoral fin. The new species is taxonomically analyzed and compared with its congeners.

Pristolepis marginata Jerdon has long been placed in synonymy with Pristolepis malabarica Guenther. An examination of the specimens of the P. marginata collected recently from its type locality in Kerala shows however, that it exhibits many valid differences from P. malabarica. Jerdon's Pristolepis is distinguished from its relative species by having dorsal fin soft rays-12 ; dorsal spines-XV; anal fin spines-IV; anal fin soft rays-7-8; lateral line scales –19-21/12-15; pre orbital with 9 strong teeth; pre opercle angle with 18 serrae; Meristic and morphometric characters are analyzed well based on the topotypic materials.
