Mahasweta Guha | Viswa Venkat Gantait


Abstract: Tigronchoides jairajpurii sp. n., a new mononchid nematode under the family Anatonchidae is described and illustrated. This is found in the rhizospheric soil of paddy in the Sunderban region of South 24 Parganas district of West Bengal, India. This is characterized by a medium-sized body (1.5-1.8 mm ?), two retrorse arrows-like hanging dorsal teeth projecting downward in a roomy barrel-shaped buccal cavity with small sub ventral denticles, and the presence of foramina, longitudinal vulva, and long filiform tail with spinneret which show marked differences from other species of the genus. The species key of this genus is also provided hereunder. This finding shows a scope of mangrove fortification and paddy field safeties. Thus, it will be helpful for environment protection and economic development also.
