This species is clearly distinguished from the other species by the 2nd side-plate and the telson. Byblisoides, Brnrd. Barnard, 1931, p. 426. Head with post-antennal angle very distinct, pushed forward, so that bases of 2nd antennae are closely juxtaposed to those of 1st antennae. No corneal lenses; ocular pigment not visible. Side-plates 1-4 sloping forwards, 4 obliquely truncate below posterior corner. Telson ovate, longer than broad, cleft nearly to base.
