The suroral plate is trapezoidal and greatest in width at the anterior of the plate body. The suboral plates are relatively short, extending just posterior of the inner processes ofM1VL/R; the posterior portions of the suboral plates are flattened. The dorsal and ventral marginal plates are approximately equal in width.
