Antillocladius musci Mendes, Andersen et Saether

Antillocladius musci Mendes, Andersen and Saether, 2004: 41 , Figs 9–12 .

Material examined: Type material as in Mendes et al. (2004). BRAZIL: Santa Catarina: Urubici, Morro da Igreja , 1822 m a.s.l., 1 male, 05.xii–08.iii.2005, Malaise trap, cloud forest, L.E.M. Bizzo & H. Mozerle .

Diagnostic characters: The male can be separated from all other members of the genus by having a few apical setae on the wing membrane; setose squama; acrostichals all scalpellate, starting some distance from

antepronotum; virga long; anal point tapering, with strong lateral setae; and inferior volsella rectangular with anterior digitiform projection. The female has a wing length of about 2.0 mm and tergite IX divided. The pupa differs from that of other known species by having antennal sheath with pearl row, and thorn-like anal macrosetae more than half as long as the distance by which the male genital sac is overreaching the anal lobe. The larva has pecten epipharyngis with about 12 teeth, mentum with 5 lateral teeth, and antennal blade longer than flagellum.

Distribution: The species is known from Santa Catarina, São Paulo, and Minas Gerais States in Brazil.
