R.], Erpenbeck [D.] & Reichenbacher [B.] 2014: 132; Type locality: Paselari spring of the Khosroshirin spring-stream system, Khosroshirin Village, Abadeh City, Fars , uppermost reaches of Kor River Basin, 30°53'29.5"N , 52°00'36.8"E , Iran , altitude 2,327 m . Holotype : ZM-CBSU, ZG151. Paratypes : ZM-CBSU, ZG225, 267–273 (8). Common name : Pr: Gormahi Shirin, En: Shirin tooth-carp. Diagnosis : Males of A. shirini can be distinguished from those of all other Iranian species by having only 7–10 wide clearly defined white flank bars, which is the lowest number of white flank bars among the Iranian inland Aphanius species , and bright to yellowish anal fin without clear white margin. Both males and females distinguished from the other in Iran Iranian by having a significantly longer caudal peduncle and a smaller dorsal fin depth. Meristic characters : D: 10–12, A: 10–11, P: 15– 16, V: 5–7, LS: 27–29, GR: 8–11, FB: 7–10. Distribution : Kor and Persis basins ( Fig. 485 ). Found in from the Khosroshirin Stream in the uppermost reaches of the Kor River . According to Esmaeili et al. (2017) translocated to the Persis basin. Taxonomy . Conservation : IUCN: Not Evaluated, PC: Endangered B2ab(iii) Populations of this species occurs exclusively in the Khosroshirin Stream, the Paselari Spring (the type locality) and Pahn Spring in Kor River Basin. The severe drought affecting the region, invasive species and population highly affect this species. Due to the occupancy area of this species being less than 500 km 2 and as it occurs in less than five localities, we classified it as Endangered.
