Diagnosis
Hemicycliophorinae.  Cephalic region broadly rounded, continuous with body.  Body conspicuously recessed just behind vulva and anterior to base of penial tube.  Female and juvenile tails elongate-conoid, filiform or cylindroid, rarely hemispherical.  Vulva lips modified, pointed, divergent, less than three body annules long.  Spicules semicircular.  Cloacal lips elongated to form a penial tube, which is less than one body width long and directed outward and forward. Pre- and postanal stretches of bursa almost equal.
