( Figs. 1−3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )

Total length. 16.2 mm (male holotype), 16.0 mm (n=2, female paratypes).

Description. External morphology as in generic description above.

Coloration. Body coloration mostly yellow and ochraceous (holotype, Fig. 2A, B View FIGURE 2 ) to brown ( Fig. 3A, B View FIGURE 3 ). Crown ochraceous (holotype, Fig. 2A View FIGURE 2 ) to brown, except for yellow anterolateral tuberosities. Frons, clypeus, and gena ( Fig. 2B View FIGURE 2 , 3B View FIGURE 3 ) dark brown, except for yellow posterior margin of gena. Pronotum, mesonotum, and forewings ochraceous ( Fig. 2A, B View FIGURE 2 ) to brown ( Fig. 3A, B View FIGURE 3 ). Thorax ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ), in lateral view, with pleurites mostly brown to dark brown, with some yellow areas of different sizes. Legs ( Figs. 2A, B View FIGURE 2 , 3A, B View FIGURE 3 ) completely dark brown. Abdomen ( Figs. 2A, B View FIGURE 2 , 3A, B View FIGURE 3 ) dark brown, with (holotype, Fig. 2A, B View FIGURE 2 ) or without median and broad yellow areas on tergites and sternites. Yellow and ochraceous to brown coloration of head, thorax and abdomen in the dead specimens are green in live ones (see Fig. 1C View FIGURE 1 ).

Male terminalia. Pygofer ( Fig. 2C View FIGURE 2 ), in lateral view, produced posteriorly, with numerous dispersed microsetae on most of the surface; without a posteroventral process; apex truncate; posterior margin sinuous, with a median concavity; ventral margin with a row of macrosetae along almost its entire length, except at base. Subgenital plates ( Fig. 2D View FIGURE 2 ), in ventral view, triangular, narrowing until mid-length and continuing almost with a constant width until apex; surface with dispersed microsetae; separate throughout their length; apex rounded; in lateral view, not extending posteriorly as far as pygofer apex. Connective ( Fig. 2E View FIGURE 2 ), in dorsal view, Y-shaped, with stem almost as long as arms; stem widening apically, not keeled; arms almost parallel. Style ( Fig. 2E View FIGURE 2 ) extending posteriorly beyond connective apex; apodeme broad and long, almost as long as apophysis; preapical present; preapical lobe triangular; base of outer apical margin of style with two little tuberosities posterior to preapical lobe; apex digitiform. Aedeagus ( Fig. 2 View FIGURE 2 F−H) symmetrical; preatrium inconspicuous; dorsal apodeme short; shaft elongate, in lateral view ( Fig. 2F View FIGURE 2 ), with dorsal margin at basal half expanded dorsally, forming a wide and triangular basal projection; anterior margin of projection with a short and acute process directed anteriorly and posterior margin of projection irregular, somewhat serrated, with irregularities continuing dorsally until shaft apex; shaft in ventral view ( Fig. 2G View FIGURE 2 ) wide at base and gradually narrowing until apex, lateral margins sinuous; shaft apex, in lateral view ( Fig. 2F View FIGURE 2 ), with ventral margin produced and curved ventrally and anteriorly, hooklike; shaft apex in caudal view ( Fig. 2H View FIGURE 2 ) wide and sagittate, with lateral margins serrated. Dorsal connective ( Fig. 2H View FIGURE 2 ) U-shaped. Paraphyses ( Fig. 2 View FIGURE 2 F−H) paired, slender and elongate; basally fused to a broad plate connected to base of aedeagus by membrane; extending posteriorly beyond shaft apex by a short distance; apex acuminate.

Female terminalia. Abdominal sternite VII ( Fig. 3C View FIGURE 3 ), in ventral view, approximately 1.5 times wider than long; subquadrate; lateral margins sinuous and convergent posteriorly; ventral surface with microsetae distributed at median area; posterior margin with rounded lateral corners and median area projected posteriorly, projected apical area bilobate ( Fig. 3C View FIGURE 3 ). Sternite VIII completely membranous. Pygofer ( Fig. 3D View FIGURE 3 ), in lateral view, produced posteriorly and directed a little upwards; apex almost truncate; surface with microsetae uniformly distributed over almost all surface, except near base; ventral margin serrated, with small cuticular dentiform projections distributed along almost all length, with one median and one preapical concavities. Ovipositor extending beyond pygofer apex. First valvifer ( Fig. 3E View FIGURE 3 ), in lateral view, subtriangular. First valvula ( Fig. 3E, F View FIGURE 3 ) with dorsal sculptured area strigate on almost all dorsal surface, strigae arranged horizontally at basal third and becoming vertical towards apex; ventral area just sculptured at apex, also strigate; apex triangular, ending acuminate. Second valvula ( Fig. 3G, H View FIGURE 3 ), in lateral view, distinctly expanded beyond basal curvature until mid-length, gradually becoming narrower towards apex; dorsal margin with 49 separate teeth, each subtriangular and wide, bigger at sub-basal expansion, each tooth with small dorsal denticles; preapical prominence distinct; apex triangular but ending rounded, ventroapical margin, beyond preapical prominence, with small denticles. Gonoplac ( Fig. 3I View FIGURE 3 ), in lateral view, with basal half narrow and apical half distinctly expanded; apex rounded.

Distribution. Colombia (Antioquia department, Fig. 1 View FIGURE 1 A−B).

Etymology. The specific epithet “ montanus ” is a Latin word that means “of the mountains”, in reference to the high mountain forests, above 2500 m, where this species is found.
