Etymology: Garra: Name based on a vernacular Indian name (Hamilton, 1822:343, Ref. 1813); a fish living in mud (Ref. 128817); sannarensis: Named after "Sannar", alternative spelling of Sennar or Sinnar, the city where the species was found (Ref. 122047).

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 9 - 10; Anale stekels: 0; Anale zachte stralen: 7 - 8; Wervels: 34 - 36. Diagnosis: From all other African Garra species except of G. napata, G. sannarensis is distinguished by: its intermediate developed sucking disc, type B, vs. fully developed disc of type C in G. blanfordii, G. chebera, G. congoensis, G. ethelwynnae, G. hindii, G. ingestii, G. makiensis, G. ornata, G. quadrimaculata, G. trewavasae, G. vinciguerrae and G. jamila, and weakly developed disc of type A in G. allostoma, G. dembecha, G. dembeensis, G. duobarbis, G. regressus and G. tana; and the absence of predorsal scales vs. presence of at least some predorsal scales in G. aethiopica, G. blanfordii, G. chebera, G. congoensis, G. dembecha, G. geba, G. hindii, G. ignestii, G. lancrenonensis, G. makiensis, G. ornata, G. quadrimaculata, G. regressus, G. tana, G. trewavasae, G. waterloti and G. vinciguerrae (Ref. 122047). Garra sannarensis is distinguished from all other species of the Main Nile basin by a caudally pointed lateroposterior flap of disc vs. rounded or absent; furthermore from G. vinciguerrae by moderately sized rostral cap and densely papillated area towards mouth vs. very prominent rostral cap with fringed but smooth posterior margin, lower-lip pad quadrangular vs. round; from G. napata and G. jamila by dorsal parts of flanks continuously covered with scales vs. naked dorsolateral flanks along anterior part dorsal fin base, and further from G. napata by its slender head and inconspicuous cheeks which are not or hardly visible when viewed from above vs. broad head and visible cheeks when viewed from above (Ref. 122047). It is distinguished from G. sp. "White Nile" by its very short barbels, which do not reach the pad when bent inwards vs. barbels nearly touching each other when flexed midways (Ref. 122047).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
