Diagnosis
ReferenceDiagnosis
J. W. M. Jagt 2000Medium- to large sized species, based on isolated marginals only, with proximal superomarginals having sloping lateral profile, gently curved outer face with two large spine bases, one on an aboral tumidity, directed obliquely upwards, the other near the intermarginal margin, and directed outwards. Ornament consisting of close-set granule-pits on well-demarcated central area. Distal superomarginals with almost flatlateral/aboral surfaces, lacking spines, and with granule pits either covering entire central area, or leaving out portion of it. Proximal and distal inferomarginals short, square or wedge-shaped, with a single large crater-shaped spine pit (directed outwards) placed centrally or slightly towards inner margin.
