- Oral aperture terminal, slit-like oriented dorsoventrally, with
2 relatively large and flat papillae on each side
- Stichosome with single row of stichocytes; except at
extremities, elongated stichocytes with granular cytoplasm, large
nuclei containing several nucleoli, and 12–17 transverse muscle
fibers per stichocyte.
- At junction with intestine, 2 pseudo-coelomocytes. Two identical
lateral bacillary bands extending along body, narrow at their
extremity, widest at midbody
- Bacillary glands conspicuous; pores opened, or not opened.
Stichosome:
The pharynx is narrow and thin-walled anteriorly; posteriorly, is
surrounded by unicellular, glandular stichocytes, each with a duct into the
pharyngeal lumen. The pharynx is almost devoid of musculature. The region of the pharynx surrounded
by stichocytes is known as the stichosome.
