Morphology | Morphometrics
soft rays: 10 - 12. This species is distinguished from its congeners in Iran by the following set of characters: anal fin rays 10-12; lateral line scales 28-32; caudal peduncle scales 10-13; gill rakers 8-10; clearly defined flank bars in males 12-19 (usually 11-13); a more prominent pigmentation along the flank added
by relatively big blotches in the middle and posterior flank segments in females; a short but high antirostrum of the otolith that has a wide excisura, and a ventral rim with some small, drop-like processes and 19 molecular apomorphies (17 transitions, 2 transversions) in the cytochrome b gene (Ref. 91277).
This species was collected from a small natural shallow pond which is about 6 x 4 m in size, fed by the drainage of a nearby natural spring. During sampling, the water body was almost stagnant, water temperature at 23°C, no vegetation in the pond, but the surrounding area was covered with Juncus sp. and Typha sp. The bottom of the pond was generally muddy with small gravels, the habitat was in a bad condition due to anthropogenic pollution. This species was the only fish observed living in the pond, but it was also found in several springs located in close proximity to the type locality (Ref. 91277).
