Silurus triostegus Heckel, 1843 – Native ( Fig. 398)

Silurus triostegus Heckel [J. J.] 1843: 1090 [100]; Type locality: Tigris River, near Mosul, Iraq. Syntypes: (4) NMW, SMF 2623 [ex NMW in 1844] (1, dry).

Common name: Pr: Gorbe mahi Tigris, Esbele-e

Tigris, En : Mesopotamian catfish.

Diagnosis: Differs from S. glanis by having robust and longer teeth (snaggly, catching on flesh and, in preserved fish at least, lower jaw teeth are exposed when the mouth is closed), the upper and lower jaws meet at a dorsal and superior position (antero-dorsal in S. glanis ), a distinctly and coarsely serrate pectoral fin spine posteriorly and a lighter color. Maxillary barbel length is about equal to head length but in S. glanis it is much longer on average, although there is some overlap. Posterior mandibular barbels longer than anterior mandibular barbels (when present) while in S. glanis , the anterior mandibular barbels are always longer.

Meristic characters: D: III–IV 3–4, A: II 77–94, P: 11–14, V: 8–13, GR: 12–17, TV: 69–70.

Distribution: Tigris basin ( Fig. 399). Found in Arvand, Bahmanshir, Karun, Karkheh and Dez Rivers.
