Analysis of the soil samples collected from around rhizospheric region of mulberry plants grown in Yurembam Rose Garden, Yurembam, Imphal West, Manipur yielded several soil and plant parasitic nematodes. 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.

Study of Aphelenchoides nematodes from different localities of Manipur were conducted for their documentation. 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.

sp. nov. was collected from two different localities of Manipur. Though the specimens collected from two different areas show some variations in their morphology and morphometric data, it was taken as the same species due to similarities in many characters. sp. nov. had females with L = 294.1-461.91 µm, a = 24.28-38.14, b = 6.3-8.65, b' = 3.61-4.68, c = 12.47-16.46, c' = 3-4.25, stylet = 10.38-13.84 µm, V = 68.88-71.69, post uterine sac = 25.98-53.63 µm long and two lateral lines. Males were common with spicule of 10.38-17.3 µm. Mucro were present in both sexes. Species presented with illustrations and morphometrics.

During a survey for the aphelenchid nematodes of North Eastern States of India, a new species of nematode was found from Kahilipara, Assam associating with the decaying plant materials of. The morphological and morphometric characteristics of the species were studied using light and Scanning Electron microscopy. sp. nov. is characterized by having 700.65-776.77 (733.30 ± 28.85) µm long body, stylet 12.11 µm long without basal swellings, two lateral lines, elongated narrow uterine sac and a cylindrical 20.76-36.33 (27.03 ± 5.03) µm long tail or about 1.36-2.37 (1.94 ± 0.43) times anal body widths long.

Survey for soil nematodes associated with mulberry plants in valley districts of Manipur revealed the presence of two new species of soil nematodes of the genus Tylenchus sp. and Telotylenchus sp. The two new species are described and illustrated here.
