Eryon cuvieri Desmarest, 1817

(Fig. 9)

STUDIED MATERIAL. — Charbonnier & Garassino (2012) listed 16 specimens including the lectotype (Appendix 1).

COMMENTS

Three of the specimens figured are in ventral view (Fig. 9 C-G), allowing the observation of nicely preserved details such as the mandibles exhibiting sharp triangular teeth of uneven size (specimen MNHN.F.GG2004/8220; Fig. 9D, E). Indeed, the preservation is usually excellent: the antennae, antennules and eyestalks of the specimens MNHN.F. A33545 and GG2004/8218 are clearly visible and they exhibit between eight and ten pereiopods. The dorsally preserved specimen MNHN.F.B13439 (Fig.9H) is also well-preserved and evidences delicate details on the carapace (branchiocardiac, postcervical and cervical grooves), telson (ponctuations and carinae).The other specimen (A33501; Fig. 9B) present some calcite bundles on the left chela.
