Frontal triangle with margins clearly sigmoid, reaching anterior margin of frons; one row of interfrontals inside frontal triangle; frons brown; gena about 1/4 eye height, postgena about half eye height; katepisternum and metepimeron blackish on ventral half; femora blackish, hind tibia dark.
Material examined. Holotype. 3, Ecuador, Pinã–N, Canãn, 01-12.xii.1970, L. E. Piñacol ( MZUSP).

Head dark brown dorsally, light brown ventrally, slightly wider than thorax, rather broader than long in dorsal view, longer than high in lateral view; frontal triangle brown, margins sigmoid, reaching anterior margin of frons; occiput dark, with fine setulae; gena light brown, about 0.25 eye height, postgena about half eye height; eye rounded, long axis diagonal; clypeus brownish, dusted; labella light brown; palpus dark brown. First flagellomere dark yellow, with dark brown area at apex; arista dark brown. One row of interfrontals inside frontal triangle; postocellars divergent; inner and outer verticals not observable; one row of setulae at lower margin of gena, no distinct vibrissa. Thorax ( Figs. 15 View FIGURES 13 – 18 , 22 View FIGURES 22 – 24 ). Scutum less than twice as long as broad, brown, with five blackish stripes, with light pilosity; scutellum brownish. Pleura dark yellow, post–pronotum light brown with a blackish mark, no bristles; black markings along ventral margin of anepisternum, and on ventral half of katepisternum and anepimeron. Halter with brown stem, yellow knob. Coxae dark yellow, fore femur and tibia black, mid and hind femora and tibiae dark brown to blackish, tibial organ brownish, tarsi dark yellow. Wing. Brownish. Costal sections one to four: 43-30-20-7. R2+3 and R4+5 slightly concave; R4+5 and M1+2 rather divergent; M1+2 apex curved downward; r-m and dm-cu paralell, distant each other 2.8 as long as dm-cu. Abdomen ( Fig. 22 View FIGURES 22 – 24 ). Tergites and sternites dark brown, segment 5 lighter. Terminalia. Hypandrium wide basally ( Fig. 23 View FIGURES 22 – 24 ). Epandrium without ventral projections; surstylus slender, with some bristles, not fused to epandrium; mesolobus bilobed ( Fig. 24 View FIGURES 22 – 24 ).

Comments. This is by far the darkest species known in the genus. The blackish markings in the pleural sclerites are shared with P. paganelliae , but this latter species is much lighter and there are obvious differences in the male terminalia.
