distinguishable one from another, each with an apical papilla, head of
male with 4 extra lateral papillae. Stoma longer than wide, anisomorphic
and anisoglottid; cheilostom an entire lip ring; dorsal metarhabdion loarge,
with a midian ridge and a pair of flanking denticles, subventral segments
each with a small denticle. Telostom hardly differentiated.
Precorpus cylindrical, swelling to a median bulb with weak crescentic,
valvular thickenings. Isthmus narrower, swelling to a terminal bulb
which contains a valvular apparatus composed of 3 triangular plates.
Vulva bedian, gonads paired, opposed, reflexed, only one egg at a time
in each uterus. Tail conical, of medium length. Male tail similar,
with 9 pairs of caudal papillae, of which 3 paris are pre-anal and the
4th pair just post-anal; last 4 pairs typically arranged. A weak
bursa present; spicules proximally knobbed; distal, slightly cuticularized
flanges of the gubernaculum flank the spicules. Tails of both sexes
