Introduction

Superorder Tylenchina. The female esophagus is composed of a procorpus, metacorpus and a glandular postcorpus with an intervening isthmus between the metacorpus and the glandular regions. A dorsal esophageal gland oriface opens in the anterior procorpus. The metacorpus generally has a valve. The stylet in males and females are generally with three basal knobs. The male feeding apparatus is atrophied in some taxa. The lip region is distinct or undifferentiated from the general body contour. Transverse body annualation is generally interrupted by longitudinal incisures. Except in aberrant males, the stoma are armed with a knobbed axial stylet. The glandular postcorpus shows varying degrees of development; it may join the intestine directly or overlap the anterior intestine for some distance. Females have one or two genital branches. The oviduct has two rows of seven cells. Males generally have caudal alae and paired spicules. The deirids are present or absent (Maggenti et al., 1987)
