Tupiperla barbosai sp.n. *

Material examinated. Holotype 3: Brazil, Rio de Janeiro, Teresópolis, Parque Nacional da Serra dos Órgãos. Rio Beija-Flor. 11–15.xi.2011. 13. A. P. M. Santos, B. Clarkson & J. L. Nessimian. Paratypes: Rio Paquequer, Ponte na Estrada, 15–18.ix.2011, 43, Malaise trap, 1,000 m, D. M. Takiya.

Measurements. RJ. 3 width of head: 0.93–1.17 mm; length of forewing: 8.33–9.31 mm (n=4).

Male. General color brown to dark brown. Head dark brown with depressed area between the posterior ocelli ( Fig. 2 ). Eyes dark brown. Three ocelli. Antenna dark brown. Labrum and palpus brown. Pronotum trapezoidal, dark brown, with roughness; median line dark. Foreleg brown; middle and posterior femora brown, with darker apex. Spine of femur keel shaped. Base of middle and posterior tibiae brown, delimited by a dark ring. Abdomen dark brown, pale in dorsal view and brown in ventral view; sterna covered by white setae. Tergum IX without pigment posteromedially lateral and anterior margins sclerotized dark brown. Tergum X pentagonal; anterior and latero-posterior margins concave; posterior margin convex. Extension of tergum X short, flattened dorsoventrally, broader at apex and slightly curved ventrad ( Fig. 3 ). Paraprocts long and robust, longer than tergum X, somewhat cylindrical, dilated and twisted dorsally on distal quarter, tapering to acute apex ( Fig. 4 ). Subgenital plate piriform, posterior margin projected with truncated apex ( Fig. 5 ).

Female and Nymph: unknown.

Remarks. Tupiperla barbosai differs from other species of the genus by the peculiar form of the paraprocts, longer and tapering to an acute apex. The structure is similar to T. oliverai Froehlich, 1998 , but in this species, the apex of paraproct is more truncated than in the new species. The apex of tergum X differs between the two species, being short in T. barbosai and long and deeply divided in T. oliverai . All specimens of T. barbosai were collected with a Malaise trap and aerial nets during day, suggesting diurnal activity of this species.

Distribution. Brazil. Rio de Janeiro.

Etymology. The patronym honors the dipterist, Leandro Silva Barbosa.
