Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 10 - 11; Afterflossenweichstrahlen: 9. Differs from other congeners by the following characters: one longitudinal narrow brown stripe running along lateral line, light brown on the first 10-11 scales after opercular opening and dark brown along the posterior remaining scales of lateral line; 11-13 short transverse dark brown bars on dorsum meeting small dark brown blotches; snout length 38.4 to 50.6% in head length; orbital diameter 24.6 to 30.9% in head length; body depth 17.7 to 24.6% of SL; sub- inferior mouth (inferior margin of superior lip horizontally aligned with the inferior margin of orbit); teeth elongated incisive-like and with a fine and straight cutting edge decreasing in size like the steps of stairs from teeth pair of jaw symphysis; 4/4 teeth on each premaxillary and dentary; 42 to 44 scales in the lateral line, 6 scales series above and 5 under the lateral line on the transverse line and 16 circumpeduncular series of scales (Ref. 80692).
Body shape (shape guide): elongated.
Distinct pairs breed on densely grown weedy places (Ref. 205).
