ANATOECUS 



Anatoeous Cummings, 1916. Proc . Zool. See. London, 1916: 653. 



Type species: Anatoeous icterodes (Nitzsch, 1818). 

 Cereopsoecus Keler, 1960. Zeitr. Parasit., 20: 238. 



Type species: Cereopsocus clayae Keler, 1960. 

 Flamingobius Keler, 1960. Zeitr. Parasit., 20: 305. 



Type species: Docophorus pygaspis Nitzsch, 1866. 



Short robust Philopteridae . Head with distinct hyaline margin, ex- 

 tending from each premarginal carina and rounded in front; large shield- 

 shape dorsal anterior plate with posterior projection. Postmarginal 

 carinae and temporal carinae well developed. Antennae filiform and 

 similar in the 2 sexes. Prothorax with 1 lateral spine-like, and 1 

 long seta at each posterolateral angle. Pterothorax with 1 lateral 

 spine-like seta on each side and 12 long setae along the dorsopos- 

 terior margin. Abdomen stout with well developed pleural plates. 

 Tergite I undivided; tergites II-VIII divided medially; tergites IX-X 

 fused, greatly narrowed, and continuous across the segment. 



At the present time it is uncertain as to whether 1 or 2 species 

 of Anatoeous infest birds of the order Anseriformes in New England. 

 The females of the 2 possible species cannot be separated and the 

 separation of the males is by the presence or absence of the "effractor" 

 (Cummings, 1916: 652) in the male genitalia. The situation is compli- 

 cated by the fact that both species may be present on the same host. 



Anatoeous dentatus (Scopoli, 1763) 



Pedioulus dentatus Scopoli, 1763. Ent . Carniolica: 

 Type host: Anas platyrhynahos Linnaeus — Mallard.
