cylindrica Macquart, 1846 , Cyrtonevra

Cyrtonevra cylindrica Macquart, 1846a: 328 ( 1846b: 200) , pl. 17, fig. 12. Lectotype ♂, “du Brésil. Collection de M. Bigot.” ( Brazil), by present designation, in BMNH.

MATERIAL. — Described from material in Bigot’s collection, and the only surviving syntype is in that part of the Bigot collection now in the BMNH. It is in appalling condition, being completely covered in mould so that virtually nothing of the colour and bristling can be seen ; three legs are missing, but it is impossible to tell which they are. It is labelled by Macquart “ Cyrtonevra / cylindrica. ♂ / Macq. n. sp.”, and stands over Bigot’s drawer label “ C. cylindrica . ♂. / Brazil. Macq.”. I have labelled it and designate it herewith as lectotype .

CURRENT IDENTITY. — Brauer (1899: 526) was unable to place it to genus. It appears to belong to Cyrtoneurina Giglio-Tos, 1893 ( Pont 1972: 52; Carvalho et al. 1993: 50; 2005: 79), but I have been quite unable to identify it specifically. The only possibility of resolving its identity was for the next reviser of Cyrtoneurina to remove it from its pin and macerate the remains, comparing structure and terminalia with the other known species. In fact, during a study visit to the BMNH, Dr Denise Pamplona removed and macerated the abdomen, storing it in a microvial of glycerine. However, the results of this study have not yet been published.
