Leptograpsus verreauxi H. Milne Edwards, 1853

( Fig. 6E )

Leptograpsus Verreauxi H. Milne Edwards, 1853: 138 [172].

CURRENT TAXONOMIC STATUS. — Junior subjective synonym of Leptograpsus variegatus (Fabricius, 1793) ( Griffin 1973: 418, 423; Davie 2002: 216; Ng et al. 2008: 217).

LECTOTYPE (by present designation). — MNHN-IU-2000-4024 (= MNHN-B4024 ), ♂ 34.9 × 39.6 mm, Australia, coll. J. P. Verreaux , 1842. Presumed Syntype, D. Guinot 1972. — Original label: “ Leptograpsus Verreauxi H. M. Edwards , Syntype, Australie, M. Verreaux”. Additional label: “ Syntype présumé, D. Guinot 1972”.

PRESERVATION OF THE LECTOTYPE. — Dry. Pleon with a small crack; telson folded inwards.

PARALECTOTYPE. — MNHN-IU-2000-3546 (= MNHN-B3546), 1♂ 30.7 × 34.1 mm, same data as lectotype. — Additional label: “Presumed Syntype, D. Guinot 1972” .

PRESERVATION OF THE PARALECTOTYPE. — Dry.

REMARKS

In 1972 Guinot wrote a new label “presumed syntypes ” for the samples MNHN-IU-2000-4024 (= MNHN-B4024) and MNHN-IU-2000-3546 (= MNHN-B3546) collected by Verreaux in Australia. Based on this information, Griffin (1973: 418, 423) mentioned that two syntypes were deposited at the MNHN when he recognised the species as a junior synonym of Leptograpsus variegatus . The larger male from the type series is selected here as lectotype. The entry date in the CAA of a considerable material of the Verreaux collection from Tasmania, Australia is 1847, which corroborates the hypothesis that H. Milne Edwards has established his new species after this Verreaux material (see Appendix).
