Diagnosis
ReferenceDiagnosis
J. R. Paterson et al. 2010Nektaspida with tagmosis composed of cephalic
shield with posterior margin nearly straight and transverse,
short thorax of three or four segments, and elongate
pygidium, much longer than cephalic shield. First
thoracic segment as wide as cephalic shield, without contraction
in width behind cephalon. Hypostome elongate,
with natant attachment, placed well behind anterior margin
of cephalic shield, divided by a transverse suture into
a subtrapezoidal anterior half with an anterior wing and
shield-shaped posterior half with a rounded posterior
margin. Antennae relatively short, laterally deflected from
their attachment behind anterior wing of hypostome;
three pairs of postantennal cephalic limbs. Pygidium with
distinct border furrow.
