Diagnosis. Distinguished from other species of Glyptothorax in West Asia by: ○ head and body pale-brown without brown or black spots / ○ head and flank with roundish or elongate warts, without tubercles / ○ thoracic adhesive apparatus strongly elevated, 1.0–1.2 times longer than wide, usually extending from isthmus to base of last pectoral ray or to posterior limit of pectoral base / ○ medial pit narrow and spear-blade shaped, without striae / ○ striae restricted to elevated apparatus / ○ anteromedial striae absent or very short / ○ caudal-peduncle 1.1–1.3 times in its length / ○ caudal lobes pointed / ○ caudal deeply forked, shortest middle caudal ray 47–53 % of longest ray of upper caudal lobe / ○ head depth 53–57 % HL / ○ maximum head width 73–80 % HL / ○ maxillary barbel 90–95 % HL / ○ inner mandibular barbel 38–42 % HL / ○ outer mandibular barbel 52–59 % HL, reaching pectoral origin / ○ 10–11 serrae on pectoral spine / ○ upper head, back and flank without brown or black spots or blotches / ○ all fins with a distinct, distal yellow tip / ○ adipose short, its length 0.5–0.8 times larger than distance between base of last dorsal ray and adipose origin. Size up to 69 mm SL, likely to grow larger.
Distribution. Iran: Sirvan drainage, including Goleyn, Alvand, Zemkan, and Sirvan.
Habitat. Fast-flowing water in mountain streams, rapids, and riffles on rocky or gravelly bottoms.
Glyptothorax sardashtensis ; Lesser Zab drainage, Iran; ~ 80 mm SL.
Biology. Nocturnal, hiding under rocks during day. Feeds on benthic invertebrates.
Conservation status. VU; appears to be declining within its small range.
Remarks. As the Sirvan flows into Iraq to join Tigris, this species is expected to occur there.
