Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Barbus lacerta is distinguished from other members of the Barbus lacerta group by having almost triangular gular region (vs. rectangular in other members of the B. lacerta group) and almost a longer anal fin; tip of the anal fin, when pressed to the body, reaches beyond the middle of the distance between the base of the last anal-fin ray and the lower caudal-fin origin, often to the caudal-fin base (vs. not reaching to middle of the distance); 0-3 (mode 2) scale rows between the tip of the anal fin and the base of the caudal fin (vs. 3-6, mode 5). It also differs from B. cyri by having a straight posterior anal-fin margin (vs. convex) and a narrow upper lip (its width 4-6 %HL vs. 7-9 % HL). Additional diagnostic characters include the following: long snout, its length 46-56% of body depth at dorsal-fin origin; eye diameter 2.5-3.1 times in snout length; 52-66+2-4 total scales along the lateral line; 35-48 (mode 39) predorsal scales; 25-32 (mode 28) circumpeduncular scales; length of caudal peduncle 1.7-2.0 times longer than depth; 60-70% of posterior margin of last unbranched dorsal-fin ray covered with denticles and median pad at lower lip small (Ref. 115584).
Inhabits rivers and lakes (Ref. 1441).
