<div>Background: Order mononchida represents predatory nematodes feeding on phytophagous nematodes and bacteria. The present study is aimed to know the diversity of mononchid nematodes in Mizoram.&nbsp; 
 
Methods: Various soil samples were collected from various parts of Mizoram. The samples were processed by sieving and decanting method followed by funnelling technique. Specimens were fixed and dehydrated using glycerine method.&nbsp; 
 
Result: Analysis of the soil samples revealed the diversity of mononchid nematodes in Mizoram. A new species of the genus Parahadronchus Mulvey, 1978 was identified after thorough analysis of the samples. Parahadronchus divendentus sp.n. could be distinguished from P. siroii and P. marami with its smaller body (female body length= 2.19-2.48 mm), two ridges of ventral buccal wall with two ventral denticles, group caudal glands with subterminal spinneret. Tail is long, filiform and about 10-12 anal body width. Male have a body length of 2.19 mm, spicule length= 68.02 &micro;m, supplements= 11, lateral guiding piece= 12.35 &micro;m in the new species.</div>
