NEMATODE PARASITES OF BIRDS

SUBULURA SIMILIS (Gendre, 1909) Travassos. 1913 



Synonym. — Heterakis similis Gendre, 19095. 



Hosts. — Centropus monachus, Coracias abyssinieus, Eurystomus 

 afer, Scops leucotis. 



Itailliet and Henry suggest that the reports from Scops leucotis 

 (Strigi forme) and Centropus monachus (Coccigy forme) may be 

 confused. Barreto considers that Gendre was dealing with several 

 species from this wide variety of hosts and suggests that the material 

 from Eurystomus afer may be Subulura recurvata, described by Lin- 

 stow from that host in Africa. 



Location. — Ceca. 



Morphology. — Subulura (p. 104) : Quite similar to Subulura suc- 

 toria but, according to Gendre, differs in general body form, which

is much more slender in ,S Y . suctoria (this does not seem to the present 

 writer a marked difference, the width of the male in S. suctoria be- 

 ing given as 330 to 359/*, of the female as 400 to 600/i, whereas that of 

 S. similis as given by Gendre is 300 to 400^ in the male and 420 to 

 500/x in the female). Disposition of the second and third pairs of 

 postanal papillae (counting from posterior end of worm) (fig 186) 

 also different in the two species (see No. 30 of key, page 107). 

 Size of S. similis varies according to host: 



in C. abyssinicus, male 9.5 mm. long by 400/x wide. 



E. afer male 13.1 mm. long by 400/x wide. 



female 18.8 mm. long by 500/x wide. 



S. leucotis male 12.6 to 15 mm. by 300 to 3G0ti. 



female 20.1 to 22.5 mm. by 420 to 500/x. 



C. monachus male 9.4 to 13.1 mm. 



female 11.1 to 18.4 mm. 

 Distribution, — Africa (Labe and Dahomey).
