Diagnosis
ReferenceDiagnosis
M. Webster 2007Biceratopsids with short, strongly divergent ocular lobes (posterior tip opposite or anterior to midlength of L1; line drawn from posterior tip of ocular lobe to contact between adaxial margin of ocular lobe and axial furrow forms angle of 25°-50° with sagittal axis). Glabella hourglass-shaped, constricted at S1 or L2; axial furrow shallow or absent at lateral margins of L1; S2 gently convex anteriorly, contacts axial furrow; S3 elongate furrow, oriented anterolaterally away from axis until contact with ocular lobes, contacts axial furrow; LA hemispherical to transversely oblate, summit slightly higher than more posterior glabellar lobes. Genal spine longer than length of LO (exsag.), base located at point of maximal cephalic width (tr., excluding genal spines). Fourteen prothoracic segments; pleural spine of T3 stout, macrospinous, blunt-tipped; first segment of opisthothorax with long axial spine. Summit of interocular area of higher dorsal elevation than summit of ocular lobes at small cephalic size (approximately 1.5 mm sagittal length).
