Type material. BRAZIL, Bahia, Senhor do Bonfim, Serra da Maravilha (12°23´S 40°12´W), holotype male, 24.I.2006. Vieira, R. & Chagas, C. (MZUEFS); 1 paratype male, same locality as holotype, 08.X.2005, Vieira, R. & Chagas, C. (MZUEFS); 1 paratype male, same locality, date and collectors as holtype (MZUEFS).

Habitat. The Serra da Maravilha is a mountainous massif located in the municipality of Senhor do Bonfim. The vegetation of the Serra da Maravilha can be characterized as a semideciduous seasonal forest (SEMARH 2007).

Etymology. montana Latin , refers to the mountainous collection locality.

Diagnosis. Eyes separated by 3 facet diameters; wing membrane with small bristles in the costal and cubital areas; gonostylus with small basal lobe with long bristles; cercus piriform with cluster of accessory tenacula confined to a dark area near the base; aedeagal apodeme oval-shaped, same length as paramere.

Description. Male. Head ( Fig. 1 ): vertex hair patch divided by a narrow medial band without bristles, Vshaped; eyes separated by 3 facet diameters; interocular suture arched; frons hair patch undivided, anterior margin with small median concavity. Antenna: scape cylindrical, 1.8X length of pedicel ( Fig. 2 ); pedicel spherical ( Fig. 2 ); flagellum with 14 flagellomeres, fusiform; all flagellomeres with neck ( Figs. 2, 3 ); flagellomere 14 smaller than preceding ones and with apiculus ( Fig. 3 ); ascoids not visible; one paratype male with flagellomeres 1 and 2 fused ( Fig. 4 ). Palpus formula = 1.0:2.0:1.9:2.9; last palpomere striated ( Fig. 5 ). Wing: wing membrane with infuscate patterns: a large dark area near the middle of the wing, with smaller darker spots in the costal region, base of M1+2, apex of the wing tip, and apex of M2 and M3 ( Fig. 6 ); bristles present in costal and cubital areas ( Fig. 7 ); Sc short; radial fork basal to medial fork; R5 ending at apex ( Figs.

6, 7). Male terminalia: hypandrium reduced, only a post-hypandrial plate present with length equal to 0.4X the length of aedeagal apodeme ( Fig. 9 ); apex of post-hypandrial plate sickle-shaped ( Fig. 9 ). Gonocoxite short, 1/ 3X the length of gonostylus, with few very short bristles on the dorsal surface and few long bristles on the ventral surface ( Figs. 8, 9 ). Gonocoxal apodeme 1/ 3X the length of aedeagal apodeme, with sclerotized anterior band ( Fig. 9 ). Gonostylus slightly curved ( Fig. 8 ), digitiform, except by the presence of a basal tubercle with long bristles ( Figs. 8, 9 ); alveoli present along entire surface ( Fig. 9 ). Epandrium subquadrate, naked ( Fig. 10 ); foramen not visible. Cerci piriform, narrow apically, wide basally with one apical tenaculum, short, filiform ( Fig. 8 ), with two small bristles near the tenaculum; cluster of accessory tenacula confined to dark area near the base, with clavate tips ( Fig. 8 ). Sternite 10 short, ending before distal margin of epandrium; apex rounded ( Fig. 10 ). Tergite 10 narrow ( Fig. 10 ). Aedeagus wider than paramere, with rounded apex, ending before paramere ( Figs. 8, 9 ); aedeagus 0.8X the length of paramere. Paramere subtriangular, narrow apically ( Fig. 9 ). Aedeagal apodeme oval-shaped ( Figs. 9, 11 ), same length as paramere, with length 2.0X the width ( Figs. 8, 9 ).
