This species belongs in Dispharynx or Synhimantus, apparently, 

 but can not be definitely placed until the male characters are known 



ACUARIA TARENTOLAE Seurat, 1916f 



Tarentola 



Hosts. — Primary: Unknown; secondary (aberrant] 

 mauritanica, and unknown usual secondary hosts. 



Location. — In stomach. 



Morphology— Acuaria sensu lato (p. 212) : Mouth (fig. 280) with 

 2 lateral lips, each provided with a conical tooth and a pair 

 of large lateral papillae situated near the origin of the cordons. 

 Cervical papillae situated at the level of the posterior edge of the 

 nerve ring, 175/* from the anterior extremity. Cordons not anasto- 

 mosing or recurrent. 



Male unknown. 



Female unknown. 



Fig. 



280. — Acuaria tap.entolae. Anterior and posterior ends op third stage 

 larva. After Seurat, 1916 



Larva, third-stage, 5.35 mm. long by 120/t wide. Cordons 145/t 

 long. Tail (fig. 280) 156^ long, ending in a small button with a 

 smooth surface. Buccal cavity 112^, muscular esophagus 504ju, entire 

 esophagus 2.2 mm. long. 



Life history. — Unknown; probably involves true intermediate 

 hosts other than lizards and true final hosts which are birds. 



Distribution. — Africa (Kouba) . 



This species belongs in Acuaria sensu stricto or Cheilospirura, 

 apparently, but can not be definitely placed until the adult male 

 characters are known. It is assumed here that a worm in this genus, 

 Acuaria sensu lato, is probably a parasite of birds when it is 

 adult and that it is an aberrant parasite of the lizard. This phe- 

 nomenon of aberrant parasitism on the part of third-stage larvae 

 of spirurids appears to be fairly common, according to the findings 

 of Seurat. 



Genus ACUARIA Bremser, 1811, sensu stricto 



Synomjms.—Spiroptera Rudolphi, 1819 in part; Anthuris Ru- 

 dolphi, 1819; Dispharagus Dujardin, 1845 in part. 



Generic diagnosis.— Acuariinae (p. 211) : Cordons directed pos- 

 teriorly, not anastomosing or recurrent. Male with 2 short, thick, 

 slightly unequal spicules and 6 to 8 pairs of postanal papillae.
