This species is easily confused with some of those recognized herein. It can be recognized by close observation of the carinae of the hind femur, having a strong, straight, transverse carina distally, and a more basal, smaller carina abruptly extending dorsally to the group of peglike setae. The similar D . oyapockensis has a rounded distal carina and a gradually ascending basal carina; even more similar are D. gravis and D . sinuicarina , which are also separated by the form of the hind femoral carinae. Description. Body length: 1.59–2.13 mm . Head: Frons dark brown, second row of setae slightly concave. Flagellomere 1 oval, brown. Palpus slightly enlarged, inflated, brown. Thorax: Scutum dark brown. Scutellum dark brown, with 2 pairs of setae; anterior seta one-half length of posterior seta. Pleuron brown. Mean costal length 0.52 wing length, range 0.51–0.53. Halter light brown. Legs yellowish-brown. Forecoxa in lateral view yellowish-brown. Foretibia with 4 dorsal setae. Foretarsomeres slender, elongate. Midcoxa brown. Hind coxa yellowish-brown. Hind coxal lobe light brown, short, with ventral, dorsally curved, bare digitiform process ( Fig. 310 ). Posterior face of hind femur with peglike setae forming dorsal line and ventral group to short line; with small carina extending under ventral group and larger, transverse carina more distally ( Figs 95–96 ). Abdomen: Abdominal tergite 1 dark brown, tergites 2–6 dark brown. Venter of abdomen gray, with few setae, larger on posterior margin of segment 5. Male terminalia brown, cercus yellow. Distribution.
