Diagnosis

Stylochidae with marginal, tentacular, and few scattered cerebral eyespots. Male and female tracts open in a common pore, or the genital pores are very close together near the hind margin. Male copulatory apparatus with papilla-like unarmed penis and seminal vesicle which is developed as a double-vesicle-system. The proximal vesicle is separated by a constriction, the muscle wall of which is distinctly fainter than that of the distal one. Prostatic vesicle with fingerlike extensions of inner glandular lining; polyglandular type. Lang’s vesicle lacking.
