Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. G. Baarli et al. 2022 | The Protatrypinae consists of genera with medium to small biconvex shells, a low profile, and a rectimarginate to weakly plicate anterior commissure. The interarea is ortho- to anacline, and the beak has a foramen with delthidal plates. The shells are costate with simple lamellae, and a weak carination is mostly present. Internally, the shell wall is thin; there are weak impressions of the ventral muscle scars, the mainly slen- der teeth have dental nuclei or small cavities, and they lack crural notches. The hinge pad is high and solid, as most typically developed in Protatrypa Boucot, Johnson & Staton, 1964. |
