M rolandi sp. n. is characterised (L= 0.77-0.93; a= 28-35; b=5.1-7.2; c= 4.5-6.1; c« = 7.5-10.3; V= 9-64) by having 3-5 mm long, rod-shaped to rounded crystalloids; amphidial apertures occupying 25-28% of the corresponding body diameter; prominent glandular bodies associated with uterus and vagina; and relatively shorter tail of 7-10 anal body diameters. G. glandulata sp. n. (L= 0.63-0.93; a= 32-47; c= 6.9-8.1; c«= 5.1-6.4; V= 80-84) is diagnosed by faintly striated cuticle with few somatic setae; prominent hypodermal glands; well-developed, non articulate cephalic sensilla; amphidial aperture occupying 20-26% of the corresponding body diameter; considerably posterior vulva with strongly protruded lips; thick muscular rectum; and a long conoid tail.
