( Figs. 2, 8 View FIGURES 1 – 12 , 14 View FIGURES 13 – 18 , 19–21 View FIGURES 19 – 21 )
Diagnosis. Frons brown; frontal triangle brown, margins slightly sinuose, not reaching anterior margin of frons, interfrontals outside frontal triangle; occiput dark, bare; gena yellow, about 1/4 eye height. Pleural sclerites more or less homogeneously brown.
Material examined. Holotype. 3, Peru (durch Schnabl), Coll. H. Loew ( USNM).
Description. Total length, 4.5 mm. Wing length, 3.7 mm.
Male. Head ( Figs. 2, 8 View FIGURES 1 – 12 ). Head brown dorsally, yellowish ventrally, as wide as thorax, broader than long in dorsal view, as long as high in lateral view; frontal triangle brown, margins only slightly sinuose, not reaching anterior margin of frons; occiput dark, bare; gena yellow, about 0.25 eye height, postgena about half eye height; eye oval, long axis diagonal; clypeus brownish, dusted; labella brown; palpus yellow basally, brown in the apex; face with a brown stripe ¾ ateriorly. First flagellomere yellow basally, dark brown on distal half; arista dark brown; one row of interfrontals external to frontal triangle; postocellars convergent; inner and outer verticals well–developed; more than one row of setulae at lower margin of gena, no distinct vibrissa. Thorax ( Figs. 14 View FIGURES 13 – 18 , 19 View FIGURES 19 – 21 ). Scutum mostly brown, with three dark brown stripes, less than twice as long as broad, with dark pilosity; scutellum dark yellow. Pleura mostly brownish, post–pronotum yellow, with a brown mark, bristles probably broken; pleural sclerites quite homogeneously dark brown. Halter with stem brown, knob pale yellow. Legs dark yellow, hind tibia dark brown, tibial organ brownish. Wing. Slightly brownish. Costal sections one to four: 16-16-4-1. R2+3 and R4+5 slightly concave; R4+5 and M1+2 paralell; M1+2 straight; r-m and dm-cu rather convergent, distant each other 2.5 as long as dm-cu. Abdomen ( Fig. 19 View FIGURES 19 – 21 ). Tergites and sternites brown, yellowish along distal margin. Terminalia. Hypandrium wide, with broad ventral projections weakly sclerotized ( Fig. 20 View FIGURES 19 – 21 ). Surstylus setose, clavate, fused to epandrium; mesolobus almost square ( Fig. 21 View FIGURES 19 – 21 ).
Female. Unknown.
Comments. The brown pleural sclerites in this species are unique in the genus, and the male terminalia also helps to clearly distinguish this species from other Psilochlorops .
