Tylolaimophorus corpulentus Eroshenko & Tepljakov, 1977  

After Eroshenko & Tepljakov (1977)

MEASUREMENTS

Holotype female: L = 1.04 mm; a = 15; b = 8.1; spear = 13 µm; V = 63.

1 paratype female: L = 1.26 mm; a = 15; b = 8.7; body width = (80) µm; spear = 13 µm; pharynx = (145) µm; tail = (38) µm; c = 33; c’ = (1.1); V = 57.

1 paratype male: L = 0.87 mm; a = 21; b = 6.7; body width = (40) µm; spear = 12 µm; pharynx = (130) µm; tail = (33) µm; c = 26; c’ = (1.0); spicules = 21 µm; gubernaculum = 5 µm.

DESCRIPTION

Female. Slightly swollen at mid-body, narrowing to the anterior and posterior ends. Cuticle thin, with fine transverse striation. Lip region slightly offset. Amphid apertures on the level of the base of lip region. Spear slender, with small basal knobs. Pharynx with an oval basal bulb. Cardia present. Ovaries paired, reflexed. Spermathecae spherical, filled with spermatozoa. Vagina short, strongly sclerotized. Intestine filling a large portion of the tail region. Tail conical, with thickened cuticle on the terminus.

Male. Smaller than female. Testes paired, symmetrical. Spicules slightly curved, without a proximal appendage. 12 supplements on the ventral side of the body anterior to the cloaca, and a post-cloacal pair at the mid-tail level. Tail shape as in female.

DIAGNOSIS AND RELATIONSHIPS

Tylolaimophorus corpulentus   is close to T. cavicaudatus   but it differs in a more swollen body (a = 15 vs 25), the presence of the post-rectal sac, and the higher number of supplements in males (12 vs 5).

DISTRIBUTION

Described from forest soil in Dalnegorsky district of Primorsky, Russia ( Eroshenko & Tepljakov 1977).
