Abstract


During present research study of soil nematode fauna, an undescribed and described species of Mylonchulus Cobb, 1916 were encountered from soil rhizosphere of chillies (Capsicum annuum L.) in Karachi, Sindh, Pakistan. Mylonchulus capsicumi n. sp., is disintiguished by its smaller body size (0.55-0.66) mm; robust body (a=16.4-18.5); buccal cavity with 6-7 transverse rows of ventro-sublateral denticles; lip region prominently set off from body contour; apex of dorsal tooth located at 77-85% of buccal cavity length from base of stoma; tail 24-26µm long with spinneret opening subdorsally; caudal glands are arranged in tandem. Furthermore, two other mononchid species namely Mylonchulus maritimus Jimenez Guirado & Murillo-Navarro, 2008 and M. polonicus (Stefanski, 1915) Cobb, 1917 were also recovered as a first account of these species from Pakistan. Morphometrics along with line drawing and photomicrographs are also incorporated herein.
