SUBULURA KIMA (Linstow, 1906) Travassos, 1913 



Synonym. — Ileterakis rima Linstow, 1906. 



Host. — Otis houbara. 



Location. — Ceca. 



Morphology. — Subulura (p. 104) : Cuticle coarsely cross-striated. 

 Mouth with 6 papillae. Mouth cavity deep; 6 teeth at opening of 

 esophagus. Esophagus ends in small bulb. Cuticle at the head end 

 of body markedly widened (lateral membranes?); this gradually 

 disappears posteriorly. 



Male 8.2 mm. long by 400/x wide. Esophagus 1/5.3, tail 1/21 of 

 total length. Gubernaculum present, three sided. Preanal sucker 

 very narrow and elongate, slit-like. Nine pairs of caudal papillae

 182, Subulura recurvata. Male tail. After Linstow, 1901. 183, Subulura 

 rima. Male tail. After Linstow, 1906. 184, Subulura rimula. Male tail. 

 After Linstow, 1903 



(fig. 183), of which 4 are preanal (the first pair near the sucker, thus 

 far removed from the other 3 which are near the cloacal aperture) 

 and 5 postanal. The right spicule 840/i long, the left 700/u, long. 



Female 9.3 mm. long by 430^ wide. Esophagus 1/5, tail 1/6.7 of 

 total length. Vulva slightly anterior to middle of body, dividing 

 it in ratio of 51 : 53. Eggs immature in specimen described. 



Life history. — Unknown; probably similar to that of Ascaridia 



galli (p. 82). 



Distribution. — Europe (Germany (Zoological Museum Koenigs- 



berg)). 



Baylis suggests that Subulura rima is a synonym of S. suctoria 



but as the descriptions of the two species are not comparable on 



certain points and as the number of caudal papillae and the spicule 



lengths differ, the present writer prefers to keep S. rima as a distinct 



species.
