Worms small, 1-10 mm long by 170-250 lm wide; found in mucous sheaths attached to host. Two cup-shaped ocelli dorsal, at anterior
end. Proboscis apparatus ventral to cerebral ganglion. Anterior proboscis chamber pyriform, 15-18 lm long. Basis robust, 30-32 lm long by 8-10 lm wide. Single stylet on
basis, 7-9 lm long. Stylet to basis ratio, 0.313-0.323. Two accessory stylet pouches anterolateral to stylet bulb, with one developing stylet (7-9 lm) in each. Middle proboscis
chamber 20-23 lm in diameter, glandular in appearance. Posterior proboscis chamber glandular, 43-50 lm long by 18-25 lm wide. Proboscis sheath greatly reduced. Body
musculature weakly developed with one band of circular muscles, one band of longitudinal muscles. Musculature with crossed myofibrils anterior to ocelli. Submuscular
glands distinct, eosinophilic, 14 (11-19) lm long by 8 (8-9) lm wide; numerous; as a field from ocelli to near anus, thinning in number anterior to ocelli. In cross section,
submuscular glands arrayed in three interspersed rows around the body, interior to muscles. Cephalic glands present; as a diffuse field, anterior to cephalic ganglia, dorsal
to esophagus; comprised of enlarged, weakly basophilic submuscular cells, leading to a frontal organ. Cephalic glands sometimes possessing dense, darkly basophilic
granules. Posterior nerve in one specimen ventral to cloaca. Gonads undeveloped.
