Panna is a genus of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers. These fishes are found in southern and southeast Asia.

Taxonomy

Panna was first proposed as a monospecific genus in 1969 by the Indian ichthyologist R. S. Lal Mohan with Otolithus microdon designated as its type species, as well as being the only species.^[1] O. microdon was described in 1849 by Pieter Bleeker, with its type locality given as Java.^[2] The genus Pachyurus is included in the subfamily Cynoscioninae by some workers,^[3] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sciaenidae, which it places in the order Acanthuriformes.^[4]

Etymology

Panna is a name that Lal Mohan did not explain but is thought to be a local name of the type species, P. macrodon in India.^[5]

Species

There are currently 3 recognized species in this genus:^[6]

• Panna heterolepis Trewavas, 1977 (Hooghly croaker)
• Panna microdon (Bleeker, 1849) (Panna croaker)
• Panna perarmatus (Chabanaud, 1926) (Armour croaker)

Characteristics

Panna croakers have a swim bladder characterised by having a pair of tubular appendages starting at the head end which divides almost at its root into a simple rear part and either a simple or branched part at the head end, entering the head through the septum transversum.^[7] The maximum published standard lengths of Panna croakers varies from 21.4 cm (8.4 in) in P. heterolepis and 50 cm (20 in) in P. perarmatus.^[6]

Distribution

Panna croakers are found in the Indo-West Pacific with P. heterolepis being found off India, Sri Lanka, Bangladesh and Myanmar; P. microdon is found in eastern Malaysia in Perak, the Gulf of Thailand, Vietnam, Borneo, eastern Sumatra and Java; and P. perarmatus is found off Vietnam, in the Gulf of Thailand and Borneo.^[7]
