nigrimanus Macquart, 1851 , Aricia

Aricia nigrimanus Macquart, 1851b: 231 ( 1851d: 258) , pl. 23, fig. 15. Lectotype ♂, South America, probably Strait of Magellan (not “Océanie. Triton-bay. Durville. Muséum”, as stated by Macquart), by designation of Pont (1967: 185), in MNHN.

MATERIAL. — There is 1 ♂ syntype in MNHN, under no. 2402 of the Macquart collection. The labels include a pink disc with the accession no. 1992.41, which refers to Durville’s Triton Bay material, and Macquart’s label “ Aricia / nigrimanus / ♂. Macq. n. sp.”. It is in good condition: both mid legs are loose, but are still held in position amongst the general cluster of legs around the pin. I have previously referred to it as the holotype, and this must be interpreted as lectotype designation by inference.

CURRENT IDENTITY. — Triton Bay is in West Papua province, Indonesian New Guinea, and this species is certainly not from New Guinea but from the southern part of South America. I identified it as a species of Helina Robineau-Desvoidy, 1830 , and as an older name for the species Helina bifimbriata Malloch, 1934 ( Pont 1967: 185; 1972: 22; Carvalho et al. 1993: 76; 2005: 117). The actual type-locality may well be the Strait of Magellan (see below under Brachypalpus pilosus Macquart, 1851 : also described from Triton Bay, but actually labelled as Strait of Magellan). Albuquerque (1951: 4, fig. 8) studied the lectotype, which he referred to as “holótipo ♂ ♀ ”, which is not a valid lectotype designation as it does not restrict the name to a single specimen (though his redescription is apparently only of the ♂), but he did not recognize it as a Neotropical species. Séguy (1937: 461; also 1938: 113) accepted it as a New Guinea species and made it the type-species of the new genus Tritonidis Séguy, 1937 .
