Leptostylum itaquaquecetubae ( Townsend, 1929)

( Figures 2 , 3 )

Leptostylum itaquaquecetubae (Townsend), 1929: 375 ( Argyreomyia ). Syntypes, nine males ( USNM) and two females ( USNM and MZSP) . Type locality: Brazil, São Paulo, Itaquaquecetuba .

Argyreomyia itaquaquecetubae ; Townsend 1941: 278 (new combination to Leptostylum ); Toma and Nihei 2006: 245 (comments on type material deposited at MZSP).

Leptostylum itaquaquecetubae, Guimarães 1971: 137 (catalogue); Wood 1985: 49 (comparison to L. leuconotum and L. pulchellum ).

Remarks

The type material of L. itaquaquecetubae is a series of 11 syntypes. Two specimens determined to be L. itaquaquecetubae are labeled as types in the MZSP collection ( Figures 2 , 3 ). One syntype is very damaged ( Figure 2 ), lacking many important structures, as already pointed out by Toma and Nihei (2006). According to label data, this specimen corresponds to a female ( Figure 2d ). The second female specimen labeled as type ( Figure 3 ), though, is not from the original series used in the description of Argyreomyia itaquaquecetubae ( Townsend 1916a) . This claim is also based on label data, whose date of collection ( Figure 3c ) does not match those from the original description. Additionally, although it clearly belongs to Leptostylum , the specimen is determined to be Muscinothelaira lutzi Townsend , whose holotype is deposited at USNM collection ( Townsend 1916b). Therefore, only one syntype of L. itaquaquecetubae is deposited at the MZSP collection.
