The female genital canal and the female atrium are lined with a 75 µm high columnar, non-ciliated epithelium and the apical side of its cells contains xanthophil granules. Additionally, gland cells discharge erythrophil granules through the epithelium of the female genital canal and that of the female atrium. These epithelia are underlain by a 50–120 µm thick muscle consisting of intermingled longitudinal and circular fibres. The common muscle coat consists of sparse longitudinal and circular muscle fibres.

matches all diagnostic features of the genus, except that the wall of its penis papilla is not irregular but smooth, and the dilated portion of the female ducts does not correspond to ovovitelline ducts, but the common ovovitelline duct. Therefore, the genus is re-diagnosed by omitting the mention of the irregular wall of the penis papilla and the dilation of the female genital ducts. This latter feature is transferred to the diagnosis of the new tribe.
