( Figs. 13–20 )

Type material. BRAZIL, Paraná, São José dos Pinhais, Serra do Mar, BR 277 KM 54, 08.XII.1986, Profaupar project, holotype male ( DZUP).

Etymology. This species is named after the Brazilian State in which it was found.

Diagnosis. Hair patch of frons undivided, with patch of scars extending to upper eye margin, nearly to suture; longitudinal veins without medial or apical enlargements; hypandrium V-shaped, narrowed medially; cercus with nine apical tenacula; membranous area of male terminalia with apical spicules; aedeagus symmetrical; parameres lateral to aedeagus with spine-like protuberances.

Description. Holotype male. Head. Eye bridge with four facet rows, separated by 1.7 facet diameters ( Fig. 13 ); interocular suture present, complete, inverted V-shape ( Fig. 13 ); hair patch of frons undivided, with patch of scars extending to upper eye margin nearly to suture ( Fig. 13 ). Antenna incomplete, scape cylindrical 1.4 times as long as pedicel ( Fig. 14 ); pedicel spherical ( Fig. 14 ); flagellomeres nodiform and asymmetrical ( Figs. 13, 15 ); flagellomeres with pair of S-shaped ascoids ( Figs. 14, 15 ); sensory organ of flagellomeres absent. Palpus formula = 1.0:2.6:2.5:2.4, last palpomere striated ( Fig. 16 ).

Wing ( Fig. 17 ). Longitudinal veins without medial or apical enlargements; medial fork basal to radial fork; R2+3 incomplete at base, not reaching R4; R5 ending beyond rounded apex of the wing.

Male terminalia. Epandrium rectangular, distal margin V-shaped, with bristles only in posterior area ( Fig. 18 ); presence of two foramina ( Fig. 18 ). Epandrium fused to hypandrium ( Fig. 19 ), Cercus pilose, long, 1.4 times as long as length of gonostylus, slightly curved, with 9 apical tenacula ( Figs. 19, 20 ). Tergite 10 smaller than sternite 10 ( Fig. 18 ). Hypandrium H-shaped ( Fig. 20 ). Gonocoxite pilose, 0.6 times as long as length of gonostylus ( Figs. 19, 20 ). Gonostylus pilose, with dorsal patch of scars at base ( Figs. 19, 20 ). Sternite 10 subtriangular apically, with micropilosity. ( Figs. 18, 20 ). Aedeagus symmetrical, bifid, 0.8 times as long as length of parameres ( Figs. 19, 20 ); membranous area present above aedeagus, plate-like, with a dorsal and apical patch of spicules ( Fig. 20 ); one pair of parameres lateral to aedeagus with spine-like protuberances. Aedeagal apodeme 2.7 times as long as length of aedeagus ( Figs. 19, 20 ); posterior prolongation of gonogoxal bridge (p.gx.bd) rounded apically.

Female. Unknown.
