Sobarocephala finnilaei Frey, 1918

( Figs 30–40 )

The Fernando de Noronha specimens( Figs 30–40 )match the redescription of S. finnilaei Frey, 1918 made by Lonsdale & Marshall 2012, which present geographical records in Brazil (S ã o Paulo and Santa Catarina) and Paraguay. The Noronhan specimen differs by a few characters, which we interpret as variations, namely: the body length is smaller, 3.8 mm [versus 5.1–5.4 mm as informed in the redescription]; face light yellow ( Fig. 31 ) [face with lateral margin and parafacial white]; antenna yellow, slightly light brown at the base of the arista ( Figs 30, 32 ) [antenna dark yellow]; scutum with black postsutural notal stripes ( Fig. 33 ) [scutum with postsutural stripes and presutural spots; stripe connected to spot by thin line]; scutellum mainly black with a thin yellow margin laterobasally ( Fig. 33 ) [scutellum entirely brown]; tergites 4 and 5 entirely black ( Fig. 33 ) [tergites 4 and 5 black with small yellow posteromedial emargination]. The terminalia ( Figs 35–40 ) is identical to the figures in the redescription, except for the thumb apparently absent [thumb short and pointed as redescribed by Lonsdale & Marshal (2012)].

Distribution. Brazil (Pernambuco, in Fernando de Noronha, S ã o Paulo, Santa Catarina) and Paraguay.
