Type data. — The type specimen of Cyrtomenus bergi, since it is 

 proposed as a new name for the preoccupied Cyrtomenus ciliatus of 

 Berg, not of Palisot de Beauvois (1805, p. 186), must be the same as 

 that which served as the type for Berg's name. That specimen was 

 cited in the original description as having come from 'Trovincia 

 Bonaerensis," Argentina. Unfortunately, this type, as well as many 

 of Berg's other types, appears to be lost, but in its absence this author 

 is accepting a female specimen in the Signoret collection (Wien) as 

 indicative of Berg's concept of this form; it is labeled "Cordoba" and 

 "Cyrtomenus ciliatus det. Berg."
