AphaniusNardo, 1827 (Actinopterygii, Cyprinodontidae) is a widely distributed genus in the Mediterranean and Persian Gulf area and includes several endangered species. The otolith morphology inAphaniusis known to represent a valuable tool for the taxonomy, and is also indicative for the genetic diversity of a particular population. The present study focuses on the otoliths of the endangeredA. ginaonis(Holly, 1929), which is endemic to the Geno hot spring in southern Iran. The taxonomic status ofA. ginaonishas repeatedly been questioned, and some scholars have argued that it merely represents a morphological variation of the widespreadA. dispar. We present a comparison of the otolith morphology ofA. ginaonis(52 specimens) with that ofA. dispar(Rüppell, 1828) from the Mehran River Basin (southern Iran) (17 specimens) and anA. disparpopulation from the Persian Gulf coast of the United Arab Emirates (32 specimens). Our data obtained from SEM pictures, otolith morphometry and statistical analyses suggest thatA. ginaonisrepresents a valid species. InA. ginaonisindividuals with a standard length exceeding 23 mm, the otolith variables length–height and rostrum length represent useful complementary diagnostic characters discriminating this species from otherAphaniusspecies. Besides ontogenetic variation, we found extremely high otolith form variability inA. ginaonis, including some otoliths with a morphology distinctly deviating from the basic morphology type. We hypothesize that these variations may be a result of the artificial introduction ofA. disparinto the Geno hot spring during the last years and subsequent hybridisation.
