First Report of two fish species of genus Pterygotrigla (Family: Triglidae) from East Coast of India

Abstract

Two species of fishes from the family Triglidae were collected from Digha Coast, Northern part of Bay of Bengal and identified as Pterygotrigla arabica (Boulenger, 1888) and P. hemisticta (Temminck and Schlegel, 1843). Both species morphologically very similar and previously considered conspecific, but present study describes sufficient interspecific difference among them on the basis of morphological characters. Both the species were first time reported from east coast of India; also this report confirms the occurrence of P. hemisticta from Indian coast.
