water snake, Xenochropis piscator were recovered. The Surface structures of head region of both nematodes have been examined
with Scanning electron microscope. The mouth region of both species is characterised by presence of two large pseudolabia
followed by cephalic bulb. Each pseudolabium bears a pair of submedian cephalic papillae and a lateral amphid. T. tiara has
four large cephalic bulbs whereas T. anomala has two large cephalic bulbs. Asansol industrial region is recorded as new
geographical area for this parasite.
