- Persian name Gurmahi-e-Darab
- English name Aphanius darabensis
- Key features It is distinguished from the other Aphanius species by the combination of four characters in both sexes: longer anal fin, larger pelvic fin, greater scale width, and symmetrically shaped triangular to trapezoid otoliths. This species has 69 apomorphic features in the mitochondrial gene sequence (cytochrome b).
- Conservation status Due to recent droughts in Iran and especially in south of Fars province, the habitats of this species are severely affected by these droughts, thereby the natural habitats of this endemic species are dried out or destroyed in Fars province (Esmaeili et al., 2014f). The populations of this species are low and it is suggested that biology and ecology be considered with conservation considerations. It is endemic species of Iran (Kul River basin) and is very valuable in terms of maintaining genetic reserves. Due to the very limited distribution, low populations and threatening factors, it is suggested to be listed as EN (endangered).
- Habitat and distribution This species is found in spring and stream habitats, and lives in shallow wetlands with appropriate vegetation. The distribution range of this species is reported in the springs of the upstream of Kul river basin. So far, it has been gathered from three habitats: the springs and streams of korsia (banki), as well as Cheshme Golabi near Darab and the Dasht-e-kenar Wetlands in the South East of Darab (Esmaeili et al., 2014f).
