synonymy of this group, we will examine in alphabetical sequence 

 each of the generic names which have been given to the different 

 members of the family, setting forth in detail its first usage, and so 

 far as necessary its subsequent treatment; and including in the list a 

 few generic names now first proposed. Generic names which cannot 

 be used are followed by an asterisk.

ANCISTROGASTER. 



1855. Stal, Ofv. k. Vet. Ak. Forh., 349: describes a single species, 

 luctuosus (from Brazil), which is therefore the type. In 1865, 

 Dohrn, in his monograph, describes other American species 

 allied to this, placing them all in a new world section of a larger 

 group, which contains many species from both hemisrmeres. 

 To this enlarged group he gives a new name. But even if his 

 view of the generic affinities were correct, the name Ancistro- 

 gaster would have to be given to the whole group. (See Opis- 

 thocosmia.) The genus is confined to the tropics of the New 

 World.
