Fig.94: The area diagram of Phoxinus, based on the geographic distribution of each species of the 

 genus and the phylogenetic hypothesis of the geniib i Fig. 93). The abbreviations of the regions are: 

 C.As.: Central Asia: E. & C.X.Am.: east and central North America: E.C.As&Eu.: east and central 

 Asia, and Europe: E.X.Am.: east North America: K.T: states of Kentucky and Tennessee of USA. 

 The name in the parentheses corresponds to the species of Phoxinus occurring in the region: bra.: 

 Phoxinus brachyurus: cum.: P. cumberlandensis: eos: P. eos: ery.: P. erythrogaster, iss.: P. issykku- 

 lensis: neo.: P. neogaeus: oreas: P. oreas: pho.: P. phoxinus: ten.: P. tennesseensis. 



The Asian portion of the ancestor of Phoxinus became the ancestor of the P. phoxinus 

 clade. This portion was split into P. brachyurus and the ancestor of the P. phoxinus species 

 complex. How this event happened needs to be better understood. P. brachyurus occurs
