Anterior to the mouth there are two small raised sections of the cuticle, each bearing four or five tubercles.
Prosopon on borders and spines consists of dense concentration of relatively fine tubercles; small number of larger tubercles scattered on pleural ridges and major spines.
Note the presence of pores (p) in between the tubercles.
A unique component of the tubercles are the small spines located around the peak of the tubercles.
The surface of the male worm is characterized by numerous raised tubercles bearing apically directed spines.
Small anterior pleural ridges carrying single rows of tubercles.
The tegument of the neck region between the suckers is devoid of tubercles and spines and has a series of circumferentially orientated ridges.
The prominences are beset with small tubercles, and are marked off into three more or less equal portions by two shallow furrows.
