Fig. 3.

Minute larva of L. illecebrosa (slab b, YKLP 11088b). Dorsal perspective. (A) Macrophotograph documenting four pairs of appendages (l1–l4, r1–r4) in the oval-shaped anterior part of the larva and a much narrower posterior part ending in a dagger-like telson (te). (B) SEM additionally revealing the hypostome (hy; see Fig. 4 C and F) and the setae or seta-like armatures on the exopods (see C and D) and the telson (see F). (C) Fluorescence microscopy showing details of the setae or seta-like armatures. (D) Close-up showing setae or spines in the exopod (ex) of post-SGA appendages 3 (r3) and 4 (r4) on the right side of the larva. The basipod (bas) and endopod (en) of r4 are also shown. (E) Close-up showing setae or spines (black arrowheads) along the inner margin of the basipod of r4. (F) Close-up showing several setae along the margin of the telson. [Scale bars: 0.5 mm (A–C); 0.1 mm (D and F); 0.05 mm (E).]
