Signoretia Kraatz, 1888, Deut. Ent, Ztschr. 32 : 176. 



type-species : Westicoodia perrisii Signoret, 1875, by substitution of Signo- 

 retia for Westicoodia Signoret. 



The author proposed this name to replace preoccupied Westwoodia Signoret. 

 Later in the same volume, 1888a : 360, recognizing that Signoretia was invalid 

 because of use in the Hemiptera in 1859 by Stal, he presented the name Bergrothia 

 as a substitute. Reitter, 1898: 54, having noted the use of Bergrothia in the 

 Coleoptera in 1S84, suggested Bergrothiella to replace Bergrothia Kraatz, 1888. 

 This substitution has not been accepted. Berg, 1899 : 78, apparently in ignorance 

 of Reitter's action, presented : "Trionymus nov. nom. pro Signoretia Kraatz 

 1888." Trionymus Berg is currently accepted as the valid name for this zoologi- 

 cal unit. 



Signorettia Targioni-Tozzetti, 1869, Soc. Ital. di Sci. Nat. Atti 11:

 Lindinger, 1931a : 89, listed the name as a synonym of Cryptoparlatorea Lindinger, 

 and 1934 : 26, 1937 : 196, of Apteronidia Berlese. Other workers have accepted 

 the genus as valid. Balachowsky, 1958b : 315, assigned it to his Parlatorina. 

 Takahashi, 1942b : 46—47, recorded the type-species as a synonym of "S. uberifera 

 (Ldgr.)."
