( Figs 247–248, 304)

Species recognition. This species is recognized by the contrastingly dark midcoxa and the structure of the hind femur, as described below. 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.
