Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L.E. Popov et al. 1999 | Small Kellerella with very short jugal processes and spiralia with up to three whorls.
Shell strongly ventribiconvex, slightly elongated, rounded sub-triangular to sub-pentagonal in outline, about 114 per cent. as long as wide and 61 per cent. as thick as long. Anterior commissure weakly parasulcate. Ventral valve subcarinate posteriorly, strongly and evenly convex in lateral profile. Ventral beak slightly acute, pointed, strongly curved dorsally. Delthyrium narrow, lacking deltidial plates. Shallow sulcus originates near the mid valve. Tongue low, trapezoidal, about 52 per cent. as wide as the valve. Dorsal valve evenly and gently convex, somewhat flattened anteriorly with a low, flattened median fold anterior to mid-length. Ventral interior with delicate teeth and small dental plates situated close to the lateral margins of the valve. Dorsal interior with small, disjunct hinge plate, delicate, anteriorly directed, slightly divergent crura and a fine, faint median ridge bisecting the adductor muscle field. Spiralia of three whorls with laterally directed apices and vestigial jugal processes near the base of the first spiralial whorls. |
