Description
Table 2. Major diagnostic characters amongst three species with a continuous or discontinuous orange line along the dorsal mid-line of the back. Data utilised for L. micra are from Bohlen and Šlechtov (2017).

| Colour on the back of body | A continuous or discontinuous orange line along dorsal mid-line | A row of rounded orange spots along the dorsal mid-line | A row of rounded orange spots along the dorsal mid-line |
| Dorsal-fin origin | Slightly posterior to pelvic-fin insertion | Slightly anterior to or superior to pelvic-fin insertion | Slightly posterior to or superior to pelvic-fin insertion |
| Caudal-fin shape | Emarginate with rounded lobes; median rays 1.2-1.5 times as long as upper lobe. | Strongly forked, with broadly pointed lobes; median rays 1.7-2.3 times as long as upper lobe. | Moderately forked, with broadly pointed lobes; median rays 1.3-1.4 times as long as upper lobe. |
