Order Diplogasterida (After Maggenti, 1991)
The labia are seldom well developed; however, a hexaradiate symmetry
is distinct. The external circle of labial sensilla may appear setose but
they are always short, never long and hairlike. The stoma may be slender
and elongate or spacious or any gradation between these two. The stoma
may be armed or unarmed; the armature may be movable teeth, fossores, or
a pseudostylet. The corpus is always muscled and distinct from the postcorpus
that is divisible into an isthmus and glandular posterior bulb. The metacorpus
is almost always valved. The female reproductive system may have one or
two ovaries and males may or may not have caudal alae; however, a gubernaculum
is always present. The male tail most commonly has nine pairs of caudal
papillae; three are preanal and six are caudal.
