( Fig. 14 View FIGURE 14 A–E)

Type material: Holotype male, BRAZIL: São Paulo, Ubatuba , Praia das Toninhas, 09.ix.2000, sweep net, H.F. Mendes ( MZUSP, slide mounted in Canada balsam). Paratypes: 14 males, as holotype ( ZMBN); São Paulo State, São Carlos, 1 male, 9.xii.1999, H.F. Mendes (UFSCar); Rio de Janeiro State, Mangaratiba, Muriquí, 4 males, 19.i.1991, A. Serpa­Fo et al. (FIOCruz). VENEZUELA: Falcón, Rio Mitare near San Luis, 11°07.930'N, 69°39.184'W, 1 male, 7.vi. 2001, 589 m a.s.l., R.W. Holzenthal, R. Blahnik, H. Paprocki, C. Cressa ( MIZA).

Diagnostic characters: The male imago can be separated from other members of the genus by having bare wing membrane; setose squama; costa moderately extended; acrostichals starting in front, all scalpellate; moderately long virga ; anal point long, nearly parallel­sided near apex, with blunt apex and weak lateral setae ; and inferior volsella long, posterior directed and digitiform.

Etymology: Named after the type locality, Ubatuba in São Paulo State, Brazil; the name is a noun in apposition.
