Rec. zool. Surv. India : 110(Part–3) : 35-36, 2010FIRST RECORD OF ERETHISTES HARA (HAMILTON, 1822) (SILURIFORMES :ERETHISTIDAE) FROM MADHYA PRADESH, INDIAJ. THILAK AND PRAVEEN OJHAZoological Survey of India, Central Zone Regional Centre168/169, Vijay Nagar, Jabalpur-482 002 (Madhya Pradesh)INTRODUCTIONSiluriformes is an important order of Pisces,comprising of approximately 2,000 species pertainingto 30 families. They are mostly confined to freshwater,but some are marine. Siluroid fishes are devoid of scalesand are popularly termed as Cat-fishes, due to thepresence of feelers or long barbels arranged aroundthe mouth. These fishes appear to use their feelers inmoving about in muddy places, and consequently haveless use for their eyes than forms that reside in clearwater. In some freshwater as well as marine forms, themales appear to carry the ova in their mouths perhapsuntil the young are produced. These fishes are creditedwith causing poisonous wounds. They are capable ofatmospheric respiration also (Day, 1889).The family Erethistidae are commonly known as the‘Moth Cats’ because of their colour pattern of the finsas being very like moth’s wings. Head is osseous above,somewhat depressed. Mouth small, gill opening narrow,eyes small. Nostrils close together, separated by a smallbarbel. Barbels eight. First dorsal fin arising slightlyinfront of the ventrals, having a serrated spine and fiveor six branched rays. Adipose dorsal present. Ventralwith six rays. Pectoral with a serrated spine.While working on the Pisces of Madhya Pradesh,the authors came across two interesting specimens of‘Moth Cats’ identified as Erethistes hara (Hamilton,1822) belonging to family Erethistidae. Globally, thisfamily is represented by 6 genera and about 25 species(De Pinna, 1996). However, only 9 species are reportedfrom India (Jayaram, 2006). Erethistes hara (Hamilton)is so far reported by Jayaram (1981, 2006); Lipton(1985); Ataur Rahman (1989) and Mamnur Rashid, et.al.(1997).Erethistes hara (Hamilton, 1822)
