Female, 0.8-0.84 mm; a = 37-39; b = 3.2 - 3.4; c
=
26-27; V = 55-59
Male, 0.88 mm; a = 39; b = 4.5; c = 31
The cuticle on the anterior part of the body and on the male tail has
fine transverse striations. Head prominent, distinctly offset by
a deep constriction, apparently with 6 lips and the usual 16 papillae.
Opening of stoma surrounded by 4 very small cuticular elements. Spear
about 3/4 head-width; spear extension paired, opposed and reflexed, the
anterior one slightly shorter than the posterior. Oesophago-intestinal
valve roundly conical in shape. Testes paired, opposed; sperms rather
large. Supplements as an adanal pair and 2 groups of 2 situated some
distance anterior to the colacal aperture. Tail conoid, not subdigitate
as in the female, tip rounded. A single lateral pore present a short
distance behind the cloacal opening and a pair of fine pores close to the
tail tip. The usual muscle bands of the male tail region are somewhat
sigmoid in shape and T. Goodey confirmed Thorne's statement that bodies
of both males and females do not lie flat but have a slight spiral twist.
Other characters as in generic
diagnosis.
