🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 15; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 8 - 9; Vertebrae: 29 - 30. Diagnosis: Haplochromis gracilifur differs from all other known paedophages from Lake Edward by its shorter premaxillary pedicel, 18.1-21.6% of head length vs. 21.6-29.1%, smaller number of lower lateral line scales, 7-9 vs. 9-15, exceptionally 7, and bicuspid outer teeth with long minor cusps . It resembles H. molossus and H. taurinus by its rounded jaws and small lachrymal bones; it differs from both by its more slender body, 30.2-34.8% of standard length vs. 33.5-38.6% and 33.9-40.1%, respectively; it is further distinct from H. taurinus by its shorter lower jaws, 42.4-44.7% of head length vs. 44.5-51.3%, and smaller eyes, 29.0-32.3% of head length vs. 32.9-40.2%; from H. molossus by its more slender jaws, 61.9-69.4% of lower jaw length vs. 67.0-87.0%, steeper gape inclination, 40-50° vs. 20-30°, and more gentle snout inclination, 10-20° vs. 45-55° . In addition, it has more outer teeth in upper jaw than H. relictidens and fewer than H. paradoxus, 26-35 vs. 16-26 and 36-65, respectively; clearly distinct from both by its smaller lachrymal bones, 13.7-14.3% of head length vs. 15.8-18.4% and 14.7-21.5%, respectively; further separated from H. relictidens by lower jaws rounded, whereas pointed in latter . Males of H. gracilifur have bright red flanks with two horizontal stripes vs. different colour patterns in all other paedophages .
