Ambycysta Drake and Hurd (1945, p. 129). 



Type species: Megalocysta chajnpioni Drake (1922b, p. 38).

Americia Stal (1873, p. 131). Synonym of Teleonemia. 



Type species: Tingis {Americia) albilatera Stal (1873, p. 131). 



Fixation: Van Duzee (1917, p. 221), by subsequent designation. 



Later citation: Monte (1947, p. 6).

Note: Established as a subgenus of Tingis; synonymized with 

 genus Teleonemia by Champion (1898a, p. 34). Lethierry and 

 Severin (1896, p. 18) wrongly treated Americia Stal as a synonym

Note: Van Duzee (1916, p. 26) wrongly treated Amm,ianus Distant 

 as a synonym of genus Physatocheila. For a discussion of nomen- 

 clatorial changes and history of the genera Ammianus, Belenus, 

 Sakuntala, and Physatocheila see Drake (1955c, p. 5; 1957b, pp. 

 31-32). This genus and its components are much confused in 

 the literature and the species have been described largely as 

 members of genus Phyllontocheila (or Phyllontochila) .

 (2), Malagasy (1).
