1a Adipose-fin length 1.5–3.0 times longer than distance between base of last dorsal-fin ray and adipose-fin origin; 13–17 serrae on pectoral-fin spine, medial pit of thoracic adhesive apparatus with striae............................. G. steindachneri
1b Adipose-fin length 0.6–1.2 times of distance between base of last dorsal-fin ray and adipose-fin origin; 7–14 serrae on pectoralfin spine; medial pit of thoracic adhesive apparatus without striae................................................ 2
2a Head and flank with tubercles (rarely absent in some individuals)................................................ 3
2b Head and flank without tubercles, with roundish or elongate warts.............................................. 4
3a Thoracic adhesive apparatus longer than wide, well delineated at its posterior margin, situated completely on a horse-shoe shaped elevation; head, back and flank with many minute tubercles and few roundish warts................ G. armeniacus
3b Thoracic adhesive apparatus as wide as long, poorly delineated at its posterior margin, only partly situated on shallow, horseshoe shaped elevation, elevation absent in many adult individuals; head, back and flank usually with large, bony, striated and elongated tubercles (absent in some individuals). ....................................................... G. cous
4a Upper head, back and flank without brown or black spots or blotches...................................... G. pallens
4b Upper head, back and flank with few or many, dark-brown spots and, or blotches (potentially faded in poorly-preserved individuals)............................................................................................. 5
5a Thoracic adhesive apparatus wider than long, as wide as long in juveniles (0.7 – 0.9 times longer than wide)...................................................................................................... G. kurdistanicus
5b Thoracic adhesive apparatus as wide as long or longer, 1.0–1.6 times longer than wide............................... 6
