Holotvpe and Type Locality of fSiomophurvnuodon idahoensis Uveno 0961:3361 : From USGS locality 
19213, Hagerman Formation, Early Pleistocene, Twin Falls County, Idaho: USNM 21900, left pharyngeal. 
Holotvpe and Type Locality of ^Acrocheilus xestes Miller and Smith ( 1967:31 : From Glenns Ferry Formation, 
Plio-Pleistocene, Owyhee County, Idaho: UMMP V55546, a nearly complete right dentary. 
Referred Specimens of IAcrocheilus cf. A. latus tCopei or IAcrocheilus cf. A. xestes Miller and Smith in 
Wagner et al. 0997:151 : From UCMP locality V95030, Signal Butte local fauna, upper Alturas Formation, 
Early Pliocene, Modoc County; no specific specimens were identified, (see Remarks). 
Distribution of Neogene f A. latus tCope) outside of California : Washington (mid-Late Pliocene) (Smith et al. 
2000); Idaho (Plio-Pleistocene). 
Remarks : According to Smith (1975:37), Uyeno (1961:342) mistakenly listed f Sigmopharyngodon idahoen¬ 
sis as fiS', hagermanensis . We think the either/or identification by Wagner et al. (1997) is confusing and 
taxonomically incorrect because both Smith (1975) and Gilbert (1998) placed f A. xestes in the synonymy 
of f A. latus. 
f Acrocheilus sp. 
Referred Specimens in Wagner et al. 11997:16-171 : From Madeline Plains local fauna, upper Alturas 
Formation, mid-Pliocene, Lassen County; no specimens mentioned. 
From Secret Valley-Mudflat local fauna, upper Alturas Formation, mid-Pliocene, Lassen County; no spec¬ 
imens mentioned. 
Remarks : Wagner et al. (1997:16) stated that the Madeline Plains local fauna may contain a new species of 
Acrocheilus. On the other hand, Smith et al. (2002:211) suggested that “.. .fossils reported as Acrocheilus 
from the Madeline Plains may be highly variable Lavinia .”
