Material. Holotype ɗ, BRAZIL, State of São Paulo, Cubatão, 23º 53’S 46º 25’W, 15/XII/1955, d’Andretta, Pereira, Werner & Martinez cols. ( MZSP); paratypes: 2 Ψ, same as holotype ( MZSP); 1 Ψ, State of São Paulo, Salesópolis, Res. Biológica Boracéia, trilha dos Pilões, 23o 39’ 02’’S 45o 53’ 39’’W, 30/III-02/IV/2001, S.T.P. Amarante & eq. cols. ( MZSP).

Diagnosis. Wing membrane hyaline with brownish stripes; gonostylus long, with strong bristles basally.

Male. Body length, 5.7–6.0 mm. Wing length, 4.5–5.0 mm. General color dark brown. Eyes blue, facets homogenous, ocellar tubercle brown, ocelli red. Gena and clypeus brownish gray, clypeus with dark setae. Antenna dark brown; scape bare, half the length of pedicel; pedicel approximately spherical; first flagellomere spherical, shorter than pedicel ( Figure 16 ). Maxillary palpus long and acuminate ( Figure 17 ). Proboscis and labella golden yellow. Occiput gray, with golden setae.

Thorax dark brown, with golden setae. Halter bare, yellowish, tip dark. Coxae brownish gray, with silvery iridescent setae; femora yellowish, tibiae darker, both with golden setae. Wing membrane hyaline with brownish stripes ( Figure 15 ); small pigmented pterostigma; R2+3 reaching C very far from R1, without distal sinuosity; R4 forking with almost right angle, without short appendage, curved medially; CuA2+A1 slightly longer than r-m; crossvein m-m close to origin of M2.

Abdomen dark brown, with golden setae, mainly on tergites. Gonocoxite and gonostylus dark brown; gonostylus long, subcylindrical but distally acuminate, with short and long distal setae, and a bunch of strong basal bristles ( Figures 18–19 ); aedeagus long; ejaculatory apodeme not exceeding base of terminalia; ejaculatory apodeme parallel; gonocoxal apodeme slightly curved inwards ( Figure 19 ); meso-anterior incision of tergite IX short ( Figure 20 ); cercus dark brown.

Female. Body length, 8.0– 8.5 mm. Wing length, 4.8–5.0 mm. Abdomen dark brown, with long golden setae on all segments. Anterior margin of sternite VIII almost rather rounded, not acuminate, hypogynial valves with five long setae ( Figure 22 ); anterior end of genital fork slightly acuminate, distal apodeme short ( Figure 23 ); cercus two-segmented, distal segment elongated ( Figure 21 ); common spermathecal ducts short, spermathecal ducts long; spermathecae slender and oblong ( Figure 24 ).

Distribution. The known distribution of this species is the Atlantic Forest areas of the State of São Paulo, from Cubatão to Boracéia.

Etymology. The species name comes from the Latin word capillosus , for hairy, as reference to the strong bunch of bristles on male gonostylus.
