fuscinevris Macquart, 1851 , Limnophora

Limnophora fuscinevris Macquart, 1851b: 236 ( 1851d: 263) , pl. 24, figs 6, 6a. Lectotype ♂, “ Buénos-Ayres. M. d’Orbigny. Muséum.” ( Argentina, Buenos Aires), by designation of Albuquerque (1950a: 242), in MNHN.

MATERIAL. — There is 1 ♂ in MNHN, under no. 1876 of the Macquart collection. It has the accession no. 9538.34, and this refers to material collected by d’Orbigny with the following notes in the d’Orbigny catalogue: “no. 42. semblable en tout à notre mouche commune de France.” It was collected on a “voyage de Buenos-Ayres à Corrientes, en remontant le Parana sur 300 lieues de longeur”, 15 February to 15 March 1827. It is dusty, with right hind leg missing ; otherwise well preserved.

Albuquerque (1950a: 241, 242, figs 1-4) studied this species and referred to the “lectótipo ♂ e 1 paralectótipo ♂ ”, but there is in fact only 1 ♂ under this name in MNHN. However, under the species Spilogaster limbatinevris Macquart, 1851 (see below, under limbatinevris ), which Albuquerque synonymized with fuscinevris , there is also a single ♂ syntype and I believe that Albuquerque, in synonymizing these names, has treated the two type-series as a single type-series for fuscinevris . This appears to have been his practice in other cases too (e.g., Aricia coeruleigaster , see above). However, his designation of the ♂ standing under fuscinevris as the lectotype for this species can be accepted as valid.

CURRENT IDENTITY. — Limnophora fuscinevris is a junior synonym of Neurotrixa felsina (Walker, 1849) ( Pont 1972: 48; Lopes 1985: 68; Carvalho et al. 1993: 61, 62; 2005: 100; Costacurta & Carvalho 2005: 928).
