A new species of the Asian catfish, Pseudolaguvia flavipinna (Teleostei: Erethistidae) from West Bengal, India
Author(s): Somnath Bhakat
Abstract: Pseudolaguvia flavipinna, a new species of erethistid catfish is described from Mayurakshi River, a Western tributary of Bhagirathi River system of India. It differs from congeners in having yellowish fin tip and two dark black bands on the body. It can be further distinguished from other congeners of West Bengal by longer preanal, prepelvic, caudal fin length and head length. Though caudal peduncle length is shorter but caudal peduncle depth is maximum compare to other species. PCA and heat map showed that
P. flavipinna is distinctly separate from other five species of
Pseudolaguvia of West Beng
