Potamanthus (?) inanis . – Eaton, 1888: 296 (incertae sedis).

Leptohyphodes inanis . – Ulmer, 1920a: 50-51 (transfer). – Domínguez et al., 2006: 279.

Accepted name: Leptohyphodes inanis (F.-J. Pictet, 1843).

Locus typicus: “… elle provient du Brésil ” [Rio de Janeiro].

Type material: NMW; 7 syntypes (Fig. 6A): 6 ♂ imagines, Shtt.[Schott] (blue label) / Pictet vidit; 1 ♂ imago, Shtt.[Schott] (blue label) / Pictet vidit / Leptohyphodes (Ulm.) inanis Pictet Typen [Ulmer’s handwriting] .

Remarks: Some specimens are more or less damaged but on the whole in comparatively good condition (Fig. 6 B-C). Heinrich Wilhelm Schott collected in Rio de Janeiro during 1817-1821, where he was practically all the time restricted to the vicinity of the city (Schott, 1822). Two of his excursions reached Canta Gallo (= Cantagalo 21°58” S 42°22 ”W) and Macacú (22°42’S 43°02”W). Ulmer (1921: 244) listed “acht Typen ” and provided a redescription of the material. It seems probable that Kollar sent just a sample of 2 specimens to F.-J. Pictet (he based his description on “... deux exemplaires secs”), and afterwards labelled the complete series. F.-J. Pictet, however, seems to have recognized this and according to the International Commission on Zoological Nomenclature (1999: article 72.4.1.1), the seven existing specimens constitute the type series. Leptohyphodes inanis is the type species of the genus Leptohyphodes Ulmer, 1920a and is so far only known from Brazil (Domínguez et al., 2006).
