Max. size:  5.2 cm SL (male/unsexed)
Environment:  demersal; freshwater
Distribution:  Asia: Minab River drainage in Iran.
Diagnosis:  Paraschistura hormuzensis can be diagnosed from the following congeners in Iran by a combination of these non-unique characters: from P. bampurensis by having only 7-10 dark-brown bars on the flank (vs. 11-18) and the pelvic fin reaching to or beyond the anus, to the anal-fin origin in some individuals (vs. not reaching to the anus, usually reaching about 1-2 eye diameter in front of the anus); from P. abdolii, P. cristata, P. kessleri and P. turcmenica by having the body fully covered by scales (vs. body scaleless or scales restricted to the caudal peduncle); from P. abdolii by a stout and deep body (body depth at dorsal-fin origin 13-18 % SL vs. 10-14 %) and from P. cristata by the absence of a dorsal adipose crest (vs. presence) and an incomplete lateral line (vs. complete) and from P. abdolii, P. aredvii, P. cristata, P. kessleri, P. nielseni and P. turcmenica by having a suborbital flap in males (vs. absent) (Ref. 103390). Description: caudal fin forked or deeply emarginate; Dorsal fin with 7 1/2 and anal fin with 5 1/2 branched rays; pectoral fin with 10 rays; and pelvic fin with 7 rays; body covered by embedded scales, except on back in front of dorsal fin and belly; anal-, pelvic- and pectoral fins hyaline or with few dark-brown or black spots on rays (Ref. 103390).

IUCN Red List Status: Not Evaluated (N.E.) Ref. (130435)

Country info:  Known from Rudan, a tributary of the Minab River, which flows to the Strait of Hormuz about 70 km east of Bandar Abbas. Possibly endemic to the Minab drainage but this needs confirmation (Ref. 103390). Also Ref. 106249.
