Etymology: numidiensis: Luciobarbus numidiensis is named for Numidia, an ancient Berber kingdom, located in Algeria; the capital of Numidia was Cirta, the present city of Constantine; the El-Kebir River, the habitat of L. numidiensis flows through Constantine; an adjective (Ref. 121680).

背棘 (總數) : 0; 背的軟條 (總數) : 12 - 13; 臀棘: 0; 臀鰭軟條: 8. Diagnosis: Luciobarbus numidiensis is distinguished from other Luciobarbus species from the African Mediterranean Sea basin by a combination of characters, none of them unique (Ref. 121680). It is distinguished from L. callensis by having a longer anal fin, 19-23% of standard length vs. 16-19%, a wider anal-fin base, 6.5-10% of standard length vs. 6.5-8%, and a longer distance between the pectoral and pelvic-fin origins, 27-30% of standard length vs. 22-29%; it is distinguished from L. setivimensis by having a longer pectoral fin, 74-94% of head length vs. 69-84%, a longer predorsal length, 49-55% of standard length vs. 46-52%, a wider caudal peduncle depth, 12-14% of standard length vs. 11-13%, and a smaller eye diameter, 11-22% of head length vs. 11-28% (Ref. 121680). It is distinguished from Luciobarbus guercifensis by having thin barbels vs. thick, the rostral-barbel origin placed clearly behind the tip of the snout vs. rostral-barbel origin at the extreme anterior of the snout; it is distinguished from L. chelifensis, L. mascarensis and L. leptopogon by having 43-47 + 1-2 lateral line scales vs. 41-43 + 1-2 in L. chelifensis and L. leptopogon, usually 41 + 1-2 in L. mascarensis (Ref. 121680). Luciobarbus numidiensis is further distinguished from L. chelifensis and L. rifensis by having a longer anal fin, 19-22% of standard length vs. 17-19% in L. chelifensis and 16-19% in L. rifensis; it is distinguished from L. leptopogon by having a greater caudal peduncle depth, 12-14% of standard length vs. 10-13%, and from L. yahyaouii by having a longer distance between the pelvic and anal-fin origins, 23-26% of standard length vs. 20-24% (Ref. 121680). It is also distinguished from L. mascarensis, L. lanigarensis and L. yahyaouii by having a shorter predorsal length, 48-55% of standard length vs. 53-58% in L. mascarensis, 54-59% in L. lanigarensis and 53-57% in L. yahyaouii; it is also distinguished from L. lanigarensis by having a smaller prepelvic length, 49-56% of standard length vs. 55-60%, a greater postorbital length, 46-52% of head length vs. 42-48%, and the last unbranched dorsal-fin ray ossified and serrated at 2/3 of its length vs. last unbranched dorsal-fin ray serrated along almost its entire length (Ref. 121680).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00502 - 0.02185), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
營養階層 (Ref. 69278):  2.9   ±0.3 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
