Diagnosis
ReferenceDiagnosis
A. Williams 1962Subquadrate, concavo-convex Eoplectodonta with an evenly convex to subcarinate transverse profile and rarely plicate anteriorly, pedicle valve almost three-fifths as long as wide; radial ornamentation consisting of differentially thickened parvicostellae, with a modal count of 15 costellae per 2 mm. in the median portions of pedicle valves about 5 mm. anterior of the umbones; postero-lateral rugae paired, acutely inclined to the hinge-line and more commonly numbering less than 7 within 5 mm. of the right side of the ventral umbo; elliptical impressions of ventral muscle-field broad, divided by a median ridge and possibly up to one-quarter as long as the pedicle valve; dorsal median septum strong, rising to a blunt point in the posterior half of the brachial valve.
