Atria elongate with glandular covering, standing vertically in XIII to which they are restricted. Vas deferens thin walled, joining the median face of the atrium about midway along the length of the latter. Each atrium narrowing distally and terminating in a well–defined penis which is visible externally on a raised papilla. Spermathecae single (in one case the spermathecal duct had 2 unequal ampullae) .
