Remarks
L. gemellarii larvae have larger eyes and a more pigmented body than L. dofleini. In flexion stages and postflexion stages, the shape of the pectoral fin differentiates these two species: in L. gemellari there is a conspicuous difference between upper and lower part of the pectoral rays whereas in L. dofleini the lower pectoral rays develop subequally with the produced upper rays.
