Cardisoma urvillei H. Milne Edwards, 1853

( Fig. 2A )

Cardisoma Urvillei H. Milne Edwards, 1853: 170 [204].

CURRENT TAXONOMIC STATUS. — Junior subjective synonym of Cardisoma carnifex (Herbst, 1796) (see Türkay 1974a: 969).

LECTOTYPE (by inference of holotype by Türkay 1974a: 969). — MNHN-IU-2000-3735 (= MNHN-B3735 ), ♂ 72.8 × 88.1 mm, Samoa, ‘Astrolabe’ Exp., presumed Type, D. Guinot 1972. — Original label: “ Cardisoma urvillei Edw. , ♂, C. obesum Dana ?, Samoa, Exp. de l’ ‘ Astrolabe’ ”; on the right chela: “ C. urvillei , Samoa ”. — Additional label: “ Type présumé, D. Guinot 1972”.

PRESERVATION. — Dry. Carapace with a crack on right gastric/ cardiac region; RP2, RP3 missing.

REMARKS

Türkay (1974a: 969, 973) considered the specimen MNHN-IU-2000-3735 (= MNHN-B3735) the only type specimen and regarded it as the holotype. Henri Milne Edwards (1853) mentioned that the chelae changed according to the age, a sentence suggesting that several individuals had been seen and the description not based on a unique specimen. Since the original description was based on more than one specimen, a holotype could not be assumed. By inference that the specimen was a holotype, Türkay (1974a) can be deemed to have designated that specimen as the lectotype (Code, Art. 74.6). The Astrolabe Expedition (1826-1829) directed by Dumont d’Urville visited Samoa: in the CAA, 1829 is the entry date for material collected during this exploration by “Quoy & Gaimard” (see Appendix).

The holotype of Cardisoma obesum Dana, 1851 , another junior subjective synonym of C. carnifex , was recently discovered in the USNM (USNM 2356). This dried holotype now consists of only the carapace and a part of the cephalothorax only, so its sex cannot be determined ( Ng 2017: 5, figs 4, 5).
