Synonym: Metabronema prevosti Choquette, 1951
Description (after Choquette 1951b). With characteristics of the genus. Slender worms, the greatest width near posterior end, cuticle with transverse striations. Mouth opening dorso-ventrally elongated, surrounded by two slightly trilobed pseudolabia, leading to vestibule. Four large cephalic papillae at base of pseudolabia ( Fig. 62 View FIGURE 62 A). Oesophagus comprises a muscular and a longer glandular portion.
Males (two specimens in “rather poor condition” were available—most measurements are for the type specimen only): 7.0 and 10.0 long. Vestibule 0.12, muscular oesophagus 0.38, and glandular oesophagus 2.91 long. Nerve ring 0.19 and excretory pore 0.30 from anterior end. Posterior end coiled with well developed caudal alae supported by four pairs pre-cloacal and five pairs post-cloacal papillae ( Fig. 62 View FIGURE 62 B). Spicules unequal: left ones 0.8 and 1.2, and right ones 0.08 and 0.12. Gubernaculum not seen.
Females (14 specimens were available): 9.4 to 13.2 long. Vestibule 0.10 to 0.16, muscular oesophagus 0.22 to 0.39, and glandular oesophagus 1.67 to 2.35 long. Nerve ring 0.14 to 0.20, and excretory pore 0.22 to 0.25 from anterior end. Vulva situated slightly posterior to mid body. Eggs embryonated, 0.048 to 0.051 x 0.025, bear “coarse filaments at either poles which are provided with knobs”.
