Abstract : Three species of predatory nematodes belonging to the genera Miconchus, Prionchulus and Parahadronchus were found in rhizosphere of mango in Meerut district, Uttar Pradesh, India. These populations were studied in detail and on comparison with existing species in the respective genera were found to be new. Hence, these are designated as Miconchus sardhanensis sp. nov., Prionchulus prasadi sp. nov. and Parahadronchus mangiferi sp. nov. Miconchus sardhanensis is characterized by having body length=1.750-1.960 mm, a=22-25, b=3.7-3.9, c=9.3-12.3, c? 3.4-.4, and v=64-66 and was compared with closest species Miconchus citri Khan, Ahmad and Jairajpuri 1978 and Miconchus dalhousiensis n. sp. Jairajpuri 1969, Prionchulus prasadi n. sp. was characterized by having body length=1.43-1.67 mm, a=20-21, b=3.2-3.3, c=11.2-13.5, c?=3.0-3.7, v=65-66 and was separated from closest species Prionchulus muscorum and Prionchulus borealis. Parahadronchus mangiferi was characterized by body length=2.47-2.58 mm, a=24-28, b=4.2-4.3, c=6.9-7.3, c?=6.8-7.4, v=60-62 and was distinguished from nearest species Parahadronchus shakili.
