The first reporting of Ptycholaimellus macrodentatus from Indian coast is being made given due importance on the comparative morphometrics. The specimens under the present study have been found to attain a maximum length up to 1111 μm, are endowed with a long s-shaped dorsal tooth, collar enclosing the labial rugae, a groove at the base and double oesophageal bulb. All the specimens studied had a long ventral gland originated far behind of the oesophagus and opened into a small slit. This species was previously reported from the coastal Bangladesh and off the Kenyan water.
