After Husain & Khan (1967)
MEASUREMENTS
Holotype female: L = 0.49 mm; a = 18; b = 4.6; spear = 20 µm; c = 18; V = 57.
6 paratype females: L = 0.41-0.50 mm; a = 18-23; b = 4.6-5.1; body width = (28) µm; spear = 18-21 µm; pharynx = (95) µm; tail = (25) µm; c = 15-22; c’ = (1.4); V = 52-58.
1 paratype male: L = 0.41 mm; a = 21; b = 4.2; body width = (20) µm; spear = 18 µm; pharynx = (98) µm; tail = (28) µm; c = 14; c’ = (1.8); spicules = 25 µm; gubernaculum = 10 µm.
DESCRIPTION
Female. Body cylindrical, ventrally arcuate on death. Cuticle loosely fitted to the body except at head, vulva and
anus. Lip region continuous with the body contour, labial papillae elevated. Spear typical of the genus, guided by well-developed protrusion muscles. The anterior portion of pharynx cylindrical. Nerve ring about 40 µm from the anterior end. Basal pharyngeal bulb spindle-shaped. Cardia conoid. Vulva transverse. Vagina extending inward at right angles to the body axis, occupying slightly more than half of the vulval body width and surrounded by a globular area of muscles. Female gonads paired, opposed and reflexed. Intestine packed with dense granules. Rectum distinct, nearly half the anal body width long. Anal aperture prominent. Tail convex-conoid.
Male. Similar to female in general shape and appearance but with comparatively longer pharynx. Testis single, outstretched. Spicules paired, cephalated, arcuate. Gubernaculum simple. Tail shape as in female.
DIAGNOSIS AND RELATIONSHIPS
Tylolaimophorus indicus has been compared to T. digitatus ; see the discussion of that species. These two species differ from the all other species of the genus by the different structure of rectal walls (thin vs much thickened), tail shape (conical vs broadly rounded), and pharynx structure (anteriorly cylindrical vs with median swelling).
DISTRIBUTION
Described from the rhizosphere of Hibiscus rosa-sinensis L. from the Aligarh Muslim University campus, Aligarh, India ( Husain & Khan 1967).
