Cyprinion tenuiradius Heckel, 1847 – Endemic (Fig. 113)

Cyprinion tenuiradius Heckel [J. J.] 1847: 261; Type locality: Araxes and Kara Agatsch rivers. Lectotype: NMW 52814 (largest, 113 mm SL). Paralectotypes: NMW 52808–13 (1, 2, 2, 4, 2, 2), 52815–17 (1, 1, 1); RMNH 2486 [ex NMW] (2).

Common name: Pr: Lotak Qarah Aqaj, En: Qarah Aqaj lotak.

Diagnosis: Very similar to C. macrostomum but, distribution and a weak spine distinguish this taxon. The dorsal fin spine in macrostomum has teeth extending further along the spine, teeth are more well-developed even near the tip. Spine teeth in tenuiradius are more graded in size as they near the tip and are finer than in macrostomum.

Meristic characters: D: IV 11–15, A: III 6–8 (7), P: 13–18, V: 7–9, GR: 10–21, LL: 32–39, TV: 37–39.

Distribution: Persis basins (Fig. 114). Found in Dalaki, Qarah Aghaj and Mond Rivers drainage.

Taxonomy.

Conservation: IUCN: Not Evaluated, PC: Least Concern. There are many populations of this species in its distribution range, and they do not appear to be affected by losses in their habitat due to the recent years droughts and dam constructions.
