Remarks

According to article 31.2 of the International Code of Zoological Nomenclature (ICZN) (1999), a species-group name that ends in a Latin adjective must agree in gender with its respective generic name at any time combined. Since aurata is the Latin feminine declension for the adjective auratus (i.e. golden, Brown 1954), the synonymy ( Wood 1985) of Anaphorinia , feminine, to Leptostylum , neuter, implies changing the species-group name to auratum . This species was not included in Wood (1985), thus generating confusion when spelling the species-group name. Additionally, some considerations regarding type material deposited at MZSP need to be made. Although Townsend determined specimens of Anaphorinia aurata as paratypes ( Figure 1g ); a holotype was not designated in the original description ( Townsend 1927). Nevertheless, the female specimen from the type series deposited at USNM was designated as lectotype by D.M. Wood, as registered on the USNM Entomology Collection website. Type material of this species is, therefore, constituted by one female lectotype and two male paralectotypes. Both paralectotypes were listed by Toma and Nihei (2006) as paratypes [sic] of Anaphorinia aurata deposited at MZSP, one in perfect condition ( Figure 1 ) and the other very damaged (without legs, antennae, wings and setae, and with torn abdomen). However, it seems the second specimen is missing from the collection, since it could not be found.
