Male. Body length 2.4 mm , wing length 1.6 mm . Frons ( Fig. 5 ) broad, glossy black, shining, with small setulae only, lacking all usual frontal and vertical setae. Antennal flagellomere 1 enlarged, elongate­oval; arista relatively short, inserted subapically and laterally. Palpus yellowish­brown, short, rounded, with one large seta and several smaller ones. Proboscis vestigial, less than one­half length of palpus, probably non­functional. Thorax dark brown; setae of scutum greatly reduced in size. Notopleural cleft absent. Scutellum short, broad, with 4 long setae, inner pair 0.5 mm , outer pair 0.4 mm long. Anepisternum with vertical furrow, posterior portion with several short setae dorsally. Usual position of horizontal anepisternal furrow located at lateral margin of scutum, such that spiracle deflected to dorsum of scutum; spiracle large. All legs yellow­brown, relatively short. Tibiae with dorsal, longitudinal setal palisade that is deflected anteriorly at apex, without anterior or posterior row of differentiated setae. Forefemur with slightly differentiated posterior seta near apex. Foretarsomeres 1–3 greatly enlarged ( Fig. 6 ), dark brown. Tarsomere 1 of mid­ and hind leg slightly darkened. Basal costal margin of wing strongly convex ( Fig. 7 ), such that humeral crossvein is at 45 degree angle to longitudinal axis of wing. Anal region of wing strongly developed, but constricted basally; axillary margin with numerous setae. Costal setae short. All wing veins lightly sclerotized and difficult to see. Wing vein Sc not visible, even with slide mounting and phase contrast lighting. Wing vein R2+3 incomplete or absent, although costa thickened in the area where it usually occurs. Apex of vein R4+5 slightly thickened. Vein Rs with slight ventral thickening at origin of vein M2. Halter dark brown. Abdominal tergites matte dark brown, except tergites 4–6 glossy, shiny. Abdominal venter gray, bare. Terminalia ( Fig. 8 ) dark brown, approximately symmetrical. Epandrium elongate posteriorly, with raised lateral area. Hypandrium and aedeagal structure not observed in detail. Cercus yellow, large, with small setae; with lateral lobe­like projection subapically. Hypoproct elongate, narrow. Female. Unknown.
