Styringomyia americana Alexander, 1914, nomen dubium

Styringomyia americana Alexander, 1914: 231 (description), Figure 1 (wing venation).

MATERIAL EXAMINED. Holotype. Sex unknown, Mallali, Demerara (ca. 6º46N, 58º10W), British Guyana, March 8, 1913, H. S. Parish (USNM). Most of the specimen pinned; left wing mounted on separate slide.

DESCRIPTION. Dimensions: see Table I.

REMARKS. Alexander (1914) superficially described this species based on two broken specimens lacking terminalia. Because the diagnostic features of the Neotropical Styringomyia species refers to the morphology of the male terminalia, the taxonomic identity of the species­group taxon S. americana cannot be determined from its name­bearing type, and according to the International Code of Zoological Nomenclature (ICZN, 1999), it can be considered a nomen dubium. The holotype was identified by Alexander (1914: 231) as a male, although in the holotype label it is indicated that the specimen is a female. The information available does not allow the unambiguous determination of the sex of this specimen.
