 Type material. Holotype: ♂, Brazil, Roraima, Boa Vista, Cauamé river, 60°66`00``W– 02°51`00``S, 28- 30.v.2009, L.M. Fusari-LEIA. Paratypes: 3 ♂♂, same data as holotype-LEIA; 4 ♂♂, same data as holotype-DZUP; ♂, Amazonas, Manaus, Coari, igarapé Martha, 63°13`89``W– 04°13`33``S, 5-6.xi.2007, S. Couceiro-LEIA; 2 ♂♂, same previous data— DZUP.   
 Diagnostic characters. Ablabesmyia cauame sp. n. differs from other species by the combination of the following characters: antepronotal lobe with 9 setae, femora with 2 bands, middle and hind tibiae with 3 bands, tapered megaseta, grooved aedeagal blade, dorsal lobe with fringe.   
 Etymology. Named after Rio Cauamé, its type locality.

 Coloration (Fig. 3A–F): wings and abdomen follow figures 3A and 3E, respectively. Legs: P I —femur with 2 bands, tibia with 4 bands; P II, P III —femora with 2 bands, tibiae with 3 bands. Ratio of bands, related tibiae and tarsomeres 1 follow table 4. Hypopygium: gonocoxite apex and gonostylus base brown.

 Thorax: antepronotals 9; humerals 7–9; prealars 18–24; supraalar 1; scutelars 22–25.   
 Legs (Fig. 3B–D): P I –apex of tibia 46–48 µm wide and with apical pectinated spur 49–52 µm long, spur ratio 0.61–0.66; tarsomeres 1 with 2 pseudospurs 60–70 µm long. P II –apex of tibia 43–45 µm wide and with 2 apical pectinated spurs 54–57 and 40–44 µm long, spurs ratio 0.54–0.60 and 0.55–0.61 respectively; tarsomeres 1–3 with 2 or 3 pseudospurs 45–73 µm long. P III –coxa with 5 central microsetae; apex of tibia 46–47 µm wide and with 2 apical pectinated spurs 54–57 and 43–45 µm long, spurs ratio 0.62–0.63 and 0.58–0.63 respectively; tarsomeres 1–2 with 1 or 2 pseudospurs 58–72 µm long. Lengths and proportions of leg segments table 5.   
 Hypopygium (Fig. 3F–I): tergite IX with 2 central setae; anal point covers partially the aedeagal complex; phallapodeme 43–46 µm long; sternapodeme 100–110 µm long; gonocoxite 123–128 µm long and 88–91 µm wide; gonostylus 138–142 µm long, with 5 apical teeth; tapered megaseta; HR 0.88–0.91; HV 2.34–2.61. Aedeagal complex: grooved aedeagal blade 42–43 µm long and base 11–12 µm, 9/10 5 µm; dorsal lobe club-shaped with fringe, 15–16 µm long and base with 9 µm, lateral lobe and basidorsal lobe present.
