Surface microtopographical details of Catatropis indicus inhabiting the intestine of Gallus gallus dom. have been studied using scanning electron microscope. The elongated body of the fluke is free from any spines; however, tegument surrounding the oral sucker is provided with domed uniciliated papillae. Twelve pairs of gland-like ventral papillae are present on each side of the mid-ventral ridge. Four types of tegumental structures viz., blunt elongated, pointed elongated, scale-like short with round tip, and cilia-like densely packed, are present on the ventral surface. The dorsal surface is free of any papillated structures.
