Discussion on the Synonymy of Phoxinus 



The synonymy of Phoxinus differs with the views of various authors. Thus the content of 

 the genus changed from time to time. The synonymy used most are those of Berg (1949), 

 Banarescu (1964), and Howes (1985). 



Synonymies in Banarescu (1964) and Howes (1985) are modified from those by Berg 

 (1949). Gila of North America in the synonymy of Berg (1949) was removed and consi- 

 dered a distinct taxon (Miller 1945; Uyeno 1960). Eulinneela, Lagowskiella, Eupallasel- 

 la, and Czekanowskiella were deleted from, and Chrosomus was added to, the synonymy 

 in Berg (1949) by Banarescu (1964). Howes (1985) reviewed the synonymy of Berg (1949) 

 and Banarescu (1964), and generally agreed with Banarescu (1964), except for deletion 

 of Phoxinus of Agassiz, Rhynchocyprin, and Moroco from, and adding of Eulinneella, 

 lAcahara, and Parchrosomus to the synonymy of Banarescu (1964). 

 The synonymy of Phoxinus proposed herein agrees with those of Howes (1985), except 

 the differences shown in Tab. 2. I have not had the opportunity to study the species of 

 Acahara (A. semotilus), and thus, I follow Howes (1985) in listing this name as a syno- 

 nym of Phoxinus with a question mark (?) indicating the uncertainty.

Howes (1985) This Study Reasons for Change 



Chrosomus Rafinesque 1820b:47 Chrosomus Rafinesque 1840a:236 Rafinesque (1820a) might 



appear earlier than Rafinesque 

 (1820b). See „Historical 

 Review of Phoxinus" of this 

 study. 



Type species of Chrosomus: 

 Chrosomus erythrogaster Raf. 



No Phoxinus Agassiz 1835 



Type species of Chrosomus: 

 Luxilus erythrogaster Rafinesque: 

 1820a:237 



With Phoxinus Agassiz 1 835 



Chrosomus erythrogaster Raf. 

 was originally described as 

 Luxilus erythrogaster Raf. 



Phoxinus Agassiz 1835 is a 

 synonym of Phoxinus 

 Rafinesque 1820a because 

 both were typed by the same 

 species: Cyprinus phoxinus 

 Linnaeus 



Type species of Eulinnella: Type species of Eulinnella: Phoxinus phoxinus was 



Phoxinus phoxinus Linn. Cyprinus phoxinus Linnaeus originally described as 



Cyprinus phoxinus by
