Anaticola Clay, 1936. Proc. Zool. Soc. London, 1936: 617. 

 Type species: Pediaulus erassiaormis Scopoli, 1763. 



Elongate Ischnocera, adult males and females 3-5 mm in length. 

 Clypeus narrowly rounded anteriorly. Dorsal anterior plate differing 

 slightly in the 2 sexes, that of the female generally semi-lunate, 

 longer than wide, rounded anteriorly and concave posteriorly with a 

 ventral groove containing 2 hairs arising from unsclerotized spaces. 

 Chaetotaxy of the ventral surface of the head characteristic, with hairs 

 along the lateral margins but absent in front and elsewhere sparse or 

 absent. Dorsal surface of head with 2 pustulated setae immediately 

 above the level of the large antennal fossae. Antennae with 1st segment 

 enlarged in male and 3rd segment produced at apex. Prothorax small with 

 sides slightly convex; pterothorax larger and slightly wider than pro- 

 thorax. Sternal plate of pterothorax is large although sometimes not 

 apparent, joined by a sclerotized rod to a smaller plate which projects 

 into the 1st abdominal segment. Abdomen elongate; spiracles on segments 

 II-VII. Short, rod-like parameres of male genitalia lie within the 

 mesosomal plate. Penis a straight tube, forked at proximal end.

The genus Anaticola is in need of revision. The species name 

 anseris and its subspecies are presently used to designate those 

 Anaticola found on geese.
