Diagnosis
ReferenceDiagnosis
M. Gordon 1964Delepinoceras with sutures less advanced than in type species; prongs of ventral lobe more strongly trifid than first lateral lobe. Surface of ado- lescent conch with about 70 longitudinal lirae.
A. L. Titus 2000Delepinoceras with a trifid ventral lobe where D = 50 mm, with the further condition that the lateral lobes remain undivided throughout all later ontogenetic stages. Mature sutural formula (V1.3 V1.1 V1.2 V1.2 V1.1 V1.3) LU:ID
