Etymology: Paraschistura: Generic name taken from its similarity with the genus Schistura; pasatigris: Named for Pasatigris, the ancient name of the Karun River where the type material was collected. Pas in Sanskrit means to 'touch' or to be 'bound to'. This refers to the fact that the Karun is an independent drainage but closely bound to the Tigris. A noun in apposition.

Short description
Identification keys | Morphology | Morphometrics
Paraschistura pasatigris can be diagnosed from its congeners in Iran by a combination of the following non-unique characters: a suborbital flap present in males (vs. absent in P. aredvii and a suborbital groove in P. nielseni); more slender caudal peduncle (caudal peduncle depth 1.6-1.8 times longer than deep vs. 1.1-1.4 in P. nielseni); back and flank in front of the dorsal-fin origin fully covered by scales (vs. absence of scales on the back and on the flank in front of the dorsal-fin origin in P. abdolii and P. cristata; and scales completely absent in P. kessleri and P. turcmenica); absence of a long dorsal adipose crest (vs. presence in P. cristata); pelvic-fin origin behind a vertical through the dorsal-fin origin (vs. below or slightly in front in P. naumanni). It is distinguished from P. bampurensis and P. hormuzensis by having a pointed suborbital flap in males overlapping the slit below the lachrymal bone (vs. triangular, not overlapping the slit) and a blunt snout (vs. pointed). It differs also from P. abdolii, P. cristata, P. kessleri, P. naumanni and P. turcmenica by the presence of a suborbital flap in males (vs. absence) (Ref. 103390).
