Common name: Pr: Siyah mahi Karun, Siyah mahi Coad, En: Karun scarper, Coad’s scraper

Diagnosis: Last unbranched dorsal fin ray weakly to moderately ossified and serrated in 1/3–2/3 of its length, scales small, 12–17 scales between dorsal fin origin and lateral line, 9–11 scales between anal fin origin and lateral line, 26–32 encircling least circumference of caudal peduncle, length of the longest dorsal fin ray 15–22% SL, head length 23–26% SL, mouth width 7–10% SL, bright golden greenish or silvery body coloration in life.

Meristic characters: D: III–V 8–9 (8), A: III 5, P: 16–22, V: 7–11, GR: 14–18, LL: 70–84, TV: 45–47.

Distribution: Tigris and Esfahan Basins ( Fig. 70). Found in Beshar, Behesht abad, Karun, Dez, Kashkan and Zayandeh Rivers.

Taxonomy: Based on molecular evidence, Ghanavi et al. (2016) identified the small scale population of Capoeta in Esfahan basin as C. coadi ( Fig. 69). Recently Zareian and Esmaeili (2017) described that population as C. biruni . They noted (original paper downloaded on May 25, 2018) C. birunii differs from C. coadi by 1.5% genetic distance in the Cyt b gene (Table 8 in Zareian and Esmaeili 2017), and 2.9% genetic distance in the COI gene (Table 6 in Zareian and Esmaeili 2017). According to other studies on this genus (Alwan 2010; Levin et al. 2012; Ghanavi et al. 2016; Jouladeh-Roudbar et al. 2016c 2017c d; Alwan et al. 2016), genetic distances in the Cyt b gene are often higher than those in COI. We compared the sequences of C. birunii and C. coadi which were deposited in GenBank, and we found the genetic distance differentiating them is lower than 0.5%; therefore, we think the published genetic distances by Zareian and Esmaeili (2017) are a mistake. Moreover, the morphological characters of C. birunii overlap with C. coadi . Consequently, we do not consider the population in the Esfahan basin as a distinct species, and consider C. biruni as a synonym of C. coadi .

Conservation: IUCN: Not Evaluated, PC: Least Concern. This species has many populations across its distribution range and no known major threat appears to affect them; therefore, we classified it as Least Concern.
