Diagnosis (Boardman et al., 1994, changed): Shumarditoidea that lack second-order subdivision of sutural elements
and that are characterized byprominently pouched to incipiently trifid primary external and internal lateral lobes
(L and I); during phylogeny the outer (ventral) subdivision of the I complex [(I2(v)I1, I2(d))], that is, (I2(v)) is larger
than the inner two subdivisions (I2(d) and I1), and the secondary subdivision (I2(v)/I1) is higher than the saddle
that bounds the dorsad subdivision (I1/I2(d).

Composition:  Preshumardites Plumrner & Scott, 1937, Pseudaktubites Boardman et al., 1994, and Shumardites Smith, 1903.
