Pseudolaguvia permaris, a new catfish from the Eastern Ghats of India (Teleostei: Sisoridae)

Abstract

Pseudolaguvia permaris, a new sisorid catfish is described from the Mahanadi River basin in Odisha, India. The new species can be distinguished from congeners in having the following combination of characters: serrated anterior margin of dorsal-fin spine, thoracic adhesive apparatus not extending beyond base of last pectoral-fin ray, caudal peduncle depth 8.6–10.2% SL, body depth at anus 15.3–20.2% SL, adipose-fin base length 13.6–18.1% SL, dorsal to adipose distance 11.4–14.4% SL, length of pectoral-fin spine 19.3–28.0% SL, length of dorsal-fin spine 16.5–20.4% SL, head width 21.6–25.9% SL and indistinct, creamish bands on the body.

Amblyceps crassioris, a new sisoroid catfish from Odisha, India (Siluriformes: Amblycipitidae)

“…The discovery of A. crassioris demonstrates that the distribution pattern of the genus Amblyceps in India is presently conformable with another sisoroid catfish genus, Pseudolaguvia Misra, 1976 (see Vijayakrishnan et al, 2023). Increasing evidence has shown that widespread species, which are often recognized as a single species due to very similar or indistinguishable morphology, can comprise multiple species (Bickford et al, 2007).…”
