mexicana Macquart, 1843 , Curtonevra

Curtonevra mexicana Macquart, 1843: 158 ( 1844: 315) , pl. 21, figs 9, 9a. Lectotype ♀, “de Mexique. Ma collection.” ( Mexico), by present designation, in MHNL.

MATERIAL. — Described by Macquart from both sexes in his own collection. There is no material in MNHN, but 1 ♀ is in Box G.22 of the Macquart collection in MHNL. It is labelled “162.” and stands over the label “ C. mexicana / Mexique ”. It is very mouldy, but no parts appear to be missing. I have labelled it and designate it herewith as lectotype.

CURRENT IDENTITY. — Snyder (1954: 425) thought that C. mexicana might be identical with Neomuscina tripunctata (Wulp, 1896) , and I have also listed it as a species of Neomuscina Townsend, 1919 ( Pont 1972: 50) . The lectotype does indeed belong to Neomuscina and, despite its appalling condition, I have tentatively identified it as an older name for Neomuscina praetaseta Snyder, 1949 ( Carvalho et al. 1993: 58; 2005: 94). It appears to have vein R 4+5 bare at base, one presutural acrostichal and four postsutural dorsocentral setae, hind tibia with one anterodorsal, hind femur with three dorsal to posterior preapical setae, femora and coxae yellow. Other characters, such as possible meral or proepimeral hairs or even wing-clouds, are obscured by the mould.
