limbatinevris Macquart, 1851 , Spilogaster

Spilogaster limbatinevris Macquart, 1851b: 234 ( 1851d: 261) , pl. 24, fig. 2. Lectotype ♂, Argentina (not “Tasmanie. Muséum.”, as stated by Macquart), by present designation, in MNHN.

MATERIAL. — There is 1 ♂ syntype under no. 1871 of the Macquart collection in MNHN.It has an old hand-written tag “42” and the accession no. 9538.34. This refers to material collected by d’Orbigny on a journey in South America, and no. 9538 in the d’Orbigny catalogue states: “no. 42. Semblable en tout à notre mouche commune de France ”. The specimen was collected on a journey “de Buenos-Ayres à Corrientes, en remontant le Parana sur 300 lieues de longueur”, from 15 February to 15 March 1827. This is exactly the same data as for Limnophora fuscinevris Macquart, 1851 (see above). The syntype is clearly from Argentina, and not from Tasmania as stated by Macquart. It is labelled by Macquart “ Spilogaster / limbatinevris / ♂. Macq. n. sp.”. It is in poor condition: abdomen, antennae, left wing, and all legs except left hind femur missing. I have labelled it and designate it herewith as lectotype.

This syntype was studied by Albuquerque (1950a: 241, 242), who included it in the type-series of Spilogaster fuscinevris Macquart, 1851 and designated it as paralecto- type of S. fuscinevris (see above under S. fuscinevris ). This action is, of course, quite unacceptable.

CURRENT IDENTITY. — Albuquerque (loc. cit.) established from the MNHN accessions register that this is a South American species. He synonymized it with Spilogaster fuscinevris Macquart, 1851 , and I have synonymized both names with Neurotrixa felsina (Walker, 1849) ( Pont 1972: 48; Carvalho et al. 1993: 61; 2005: 100; Costacurta & Carvalho 2005: 928).
