During the research work, a total of 12 Aphelenchoides were reported from Manipur among which 6 species were new to Science. The present article will enable the biodiversity status of Aphelenchoides nematodes of the region. Diagnosis the species, key to the species and illustrations are provided in the manuscript.

Among them four species of Aphelenchoides were recorded. Upon detailed study, two species of Aphelenchoides were found to be new to science. Aphelenchoides dhanachandi sp. n. is characterized by ventrally curved body, clearly set off cephalic region and tail ending into a sharp pointed terminus, and stylet slender, 13.6–15.3 (14 ± 0.7) μm long with indistinct basal swellings and tamarind seed-shaped median bulb. Aphelenchoides neoechinocaudatus sp. n. is characterized by straight body with four incisures in the lateral field, flatten cephalic region, slender stylet with indistinct basal swellings, 11.9 μm long, elongated pear-shaped median bulb and short tail with pointed mucro. The two species are illustrated here.

During 2006, nematode population was highest in the month of May with very high rainfall (174.2 mm). Positive correlation of nematode population was found with soil temperature, soil pH, rainfall and relative humidity and negative correlation with soil moisture. During 2007, nematode population was highest in the month of May with least soil moisture and highest rainfall (15.1 p.c. and 190.6 mm). Nematode population had positive correlations with soil moisture, temperature, pH, rainfall and relative humidity of air. During 2008, nematode population was highest in the month of April with highest soil temperature of 24.8 ...

During the study eight known and a new species were identified. Aphelenchoides aerialis sp. nov. differed from all other species of Aphelenchoides in having a tail without bifurcation and strong ventral mucro with single ventrosublateral caudal papillae in male. The known species along with the new species are described in the present study.
