The concave ventral margin of the hind femur is a useful distinguishing character. Description. Body length: 2.09–2.38 mm . Head: Frons dark brown, second row of setae concave. Flagellomere 1 rounded-oval, brown. Palpus of normal size, yellow. Thorax: Scutum dark brown. Scutellum brown, with 2 pairs of setae; anterior seta one-half length of posterior seta. Pleuron with proepisternum and dorsum of anepisternum dark brown, rest of pleuron yellowish-brown. Mean costal length 0.52 wing length, range 0.5–0.54. Halter yellow. Legs yellowish-brown. Forecoxa in lateral view yellowish-brown. Foretibia with 4 dorsal setae. Foretarsomeres slender, elongate. Midcoxa dark brown. Hind coxa yellowish-brown. Hind coxal lobe light brown (dark brown in Tayrona specimen), round. Posterior face of hind femur with short basal group of peglike setae, three rows deep; ventral margin of hind femur concave ventral to peglike setae; more distally with shallowly-concave lobe, with Y-shaped clear spot visible with light microscopy ( Figs 247–248 , 304 ). Abdomen: Abdominal tergite 1 yellow, with faint brown lateral marking, tergites 2–6 dark brown, tergite 2 yellow anteriorly in some specimens.
