PARALECTOTYPES. — MNHN-IU-2000-3573 (= MNHN-B3573), 1 ♂ 28.2 × 31.8 mm, New Caledonia. — Original label: “ Metopograpsus pictus A. M. Edw. , cat. du Muséum 225-63, Nelle Calédonie ”. — MNHN-IU- 2000-10893 (= MNHN-B10893), 1 ♂ 24.2 × 28.1 mm, 1♀ 24.4 × 24.9 mm, Nlle Calédonie, M. Beaudouin; “369-65” is written with Chinese ink directly on the carapaces of both specimens . — MNHN-IU- 2000-3572 (= MNHN-B3572), 1♂ 17.2 × 20.6 mm, New Caledonia, coll. Beaudouin.

PRESERVATION. — Dry. LP5 missing, RP4-5 dactyli missing for male MNHN-IU-2000-3573; LP2 missing for female of MNHN-IU-2000-10893; most of pereiopods missing for male MNHN-IU-2000-3572.

REMARKS

Davie (2002: 217) stated that the holotype of Metopograpsus pictus as “MZUT Cr. 1026” was deposited at the Museo Regionale di Scienze Naturali, Torino, Italy (MRSN). The previous curator of this institution has confirmed that a “ holotype, MZUT Cr. 1026” was present in their collection (Alberto Chiarle, pers. comm., Dec. 2012). It must be treated as the lectotype.

According to the CAA, the entry 225-63 designates the sample MNHN-IU-2000-3573 (= MNHN-B3573) that was collected by M. De Planche (although not mentioned on the original label) in New Caledonia and given to the Muséum by M. Aubry-Lecomte, director of the Musée des Colonies. The entry 369-65 designates the samples MNHN-IU-2000-10893 (= MNHN-B10893) and MNHN-IU-2000-3572 (= MNHN-B3572) collected in New Caledonia and given to the Muséum by M. Beaudouin (Navy Captain, see Appendix). They could be considered paralectotypes (Code, Art. 72.4).

A dry specimen labelled Metopograpsus pictus deposited at the Peabody Museum of Natural History in Yale University (YPM IZ001463) does not belong to the type series: it was collected from Dominica, West Indies, by A. E. Verrill’s sons, George and Alpheus, and sent over by A. Milne-Edwards in 1873, according to the information that we received (E. A. Lazo-Wasem, pers comm. Dec 2012).
