Notes on Netuma of India

Rahangdale, S., Rajan, K., Vinaykumar, V., Divu, D., Tarachand, K., Abdul Azeez, P. & S. Kapil. (2019). Taxonomic note on the Indian species of genus Netuma. Marine Fisheries Information Service; Technical and Extension Series, Number 240, 26-27.

In Indian waters, genus
Netuma
is represented by two species namely N. bilineata and N. thalassina (Order: Siluriformes, Family: Ariidae). Rounded shout, thin lips, inconspicuous median longitudinal groove, and higher anal fin ray count (16-19) are characters of N. bilineata while N. thalassina has conical snout, clearly visible median longitudinal groove and lower anal fin ray count (13-15). Prior to the erection of N. bilineata (earlier considered as synonym of N. thalassina) as valid species, Indian workers had difference of opinion regarding the representation of species under this genus from Indian waters.
