" Allodontichthys polylepis, new species, is described from two localities in the upper reaches of the Rio Ameca basin, Jalisco, Mexico. Its distribution is disjunct from that of the rest of the genus, which is restricted to the Rio Armeria and Rio Coahuayana systems. The new species differs from the other three species of Allodontichthys primarily in a higher lateral-line scale count. Shape differences between the four species and between the sexes are examined using multivariate morphometrics, and growth patterns for each sex (as shown by allometric coefficients) are compared. These analyses distinguish A. hubbsi from its congeners, but do not resolve the remaining three species "
