Abstract

This paper documents the occurrence of the exotc South American suckermouth armoured catishes (Loricariidae) of the genus Pterygoplichthys spp. in the drainages of Thiruvananthapuram City, Kerala. The morphological taxonomy revealed that the specimens are closely related to Pterygoplichthys disjunctvus (Weber, 1991) and P. pardalis (Castelnau, 1855), in additon to intermediary forms of unknown identty. DNA barcoding using the mitochondrial DNA cytochrome c oxidase 1 (CO1) also failed to establish the identty of the invaded species. There may be possible hybridisaton in aquariums or in fsh farms or in the wild, but this needs to be found out aided by detailed studies incorporatng different molecular markers and with sequences of topotypes. The possible threats due to Pterygoplichthys spp. invasion and management optons are discussed in the paper.
