🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 0; Dorsal soft rays (total): 8 - 10; Anal spines: 0; Anal soft rays: 15 - 16. Diagnosis: Lacustricola nitida is most similar to L. matthesi; both species share the overall diagnostic characters of body colour pattern with brilliant blue spots at scale centres, forming longitudinal lines on the flank, and creating a reflective blue body colouration; fin tips of anal- and dorsal-fin rays occasionally with narrow light blue margin in females; as well as cephalic sensory system characterized by the combination of supraorbital canal with exposed neuromasts in zigzag shaped continuous groove, at preorbital level in open groove with exposed neuromasts, whereas postorbital and preopercular sensory systems tubular with pores . Lacustricola nitida is distinguished from L. matthesi by the following unique combination of characters: dorsal and anal fins hyaline and without markings in males vs. yellow with irregularly curved dotted stripes; in both sexes, a supraorbital sensory system with three exposed neuromasts vs. four; smaller head length, 23.0-24.7% of standard length vs. 27.1-32.2%; smaller dorsal-fin base length, 8.9-12.5% of standard length vs. 15.1-18.2%; smaller postorbital length, 35-38% of head length vs. 41-45%; greater eye diameter, 43-47% of head length vs. 33-40%; larger caudal peduncle length, 171-194% in its depth vs. 130-155%; and less numerous rays in pectoral fin, 10-11 vs. 12-13 .
