SUMMARY
Colonies are erect, vincularian, with slightly flattened, subcylindrical branches, about 1-1.5 mm in diameter, bifurcating at intervals. Autozooids open all the way around the branch circumference. No median budding lamina is evident in the type material (cf. Lagaiij (1952, p. 163) who described the species as bilamellar).
Autozooids are fixed-walled and have moderately long, gently convex frontal walls containing teardrop-shaped pseudopores without spines. Maximum frontal wall width is approximately 0.20 mm. Apertures are large, longitudinally elliptical, about 0.18 mm long by 0.15 mm wide, and lack preserved peristomes.
The gonozooid is unknown.
