Distribution.—Africa (French Guinea (Labe)). HABRONEMA SEURATI Skrjabin, 1917 Host.—Primary: Fateo cenchris; secondary: Unknown. Location.—Gizzard. Morphology.—Habronema (p. 172) : Body small, attenuated at two extremities; cuticle transversely striated (fig. 252a), the striations crenate. Lateral alae very feebly developed, originating a little pos- terior to the level of the cervical papillae, which are 144/*. from the anterior end. Two lateral lips, each with a tooth on the inner sur- face; a dorsal and a ventral lip, each with a small acuminate tooth. In general, lips like those of H. mansioni (p. 179).. Fig. 252.—Habronema seubati. a, Transverse striation of body ; b, cuticular STRUCTURE OF VENTRAL SURFACE OF MALE TAIL ; C, MALE TAIL ; d, LEFT SPICULE; €, RIGHT SPICULE. AFTEB SKRJABIN, 1917 Male mm. long by 300/*, wide. Caudal alae (fig. 252c) elongate, longitudinally striated, the striations giving appearance of undula- tions. Cuticle of ventral surface of caudal region anterior to cloacal aperture has longitudinal folds 11 to 13/*. wide, the free border of each fold with teethlike projections (fig. 2525). Posterior to the cloacal aperture the ventral surface of body is smooth except for three transverse rows of small projections posterior to the first pair of postanal pedunculated papillae. Spicules (fig. 252d and e) un- equal, mm. and 450//, long. The pedunculated papillae number 4 pairs of preanal and 2 pairs of postanal; the sessile papillae, 9 to 10 toward the end of the tail and 1 large papilla on the anterior edge of cloacal aperture. Cloacal aperture 200/* from posterior end. Female mm. long by 370//, wide. Vulva mm. from pos- terior end, thus in the posterior part of body. Eggs 47//. by Please note that these images are extracted from
