( Figures 3 View FIGURE 3 a–d, 4a–d, 5a–c; Table 2 View TABLE 2 )

Examined Material: Nine specimens labeled “ R. obesa #1 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946. N° 8127”. “ R. obesa ♀ 2 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946”. “ R. obesa ♂ 3 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946”. “ R. obesa #4 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946. N° 8129”. “ R. obesa #5 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946. N° 8130”. “ R. obesa ♀ 6 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946”. “ R. obesa ♂ 7 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946. N° 8126”. “ R. obesa #8 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946. N° 8128”. “ R. obesa ♀ 9 Brazil, Mato Grosso, Salobra; 2.ix.1940 Det.: C. Malogolowkin, in 1946”. Specimens ♂ 03, ♂ 07 and ♀ 09 had the disarticulated postabdomen stored in a microvial with glycerin and attached with the respective speci- men. All specimens are deposited in the Coleção Entomológica do Instituto Oswaldo Cruz ( CEIOC)/ Fiocruz.

Diagnosis. General body color yellow-brownish; front covered with ca. 200 scattered interfrontal setulae. Frontal index 1.79 (1.65–1.91); Carina nose-like and sulcated along ca. 70% of the length of praefrons; arista with 10 (8–11) long dorsal branches and 7 (6–8) long ventral branches. Wings with cloudy spots. Body length ca. 5.02 (4.80–5.50) mm. Male and female terminalia as in figures 4a–d and 5a–c, respectively.

Description. Head ( Fig. 3 View FIGURE 3 a–c). Front homogeneously brownish, covered with ca. 200 scattered interfrontal setulae. Ocellar triangle brownish with brown ocelli. Carina nose-like and sulcated along ca. 70% (60–75) of the length of praefrons. Face and gena yellowish; antenna with flagellomore homogeneously brownish, pedicel yellow; arista with 10 (8–11) long dorsal branches and 7 (6–8) long ventral branches. Palpus yellowish with ca. 50 setae on lower part.

Thorax ( Fig 3 View FIGURE 3 a–b). Scutum and scutellum brownish (with diffuse brown stripes in some specimens). 12 irregular rows of acrostichal setulae. Three pairs of prescutellar acrostichal setae, the central one is the longest. Pleura brownish; halteres yellowish. Legs homogeneously yellow.

Wings ( Fig. 3a View FIGURE 3 ). Non-hyaline, with distal and proximal cloudy spots. Vein dM-Cu, R-M and costal cell cloud- ed.

Abdomen ( Fig. 3d View FIGURE 3 ). Proximally brownish and distally dark brown; tergites with dark brown stripes continuous.

Male terminalia ( Fig. 4 View FIGURE 4 a–d). Aedeagus round shaped, the base slightly wider than the apical portion, curved dorsal-ventrally, with a dorsal structure projected medially into the top. Epandrium microtrichose. Surstyli fused to epandrium, each surstylus with ca. 26 rod-shaped prensisetae inserted as in a concave curved row and with a first longest and sharp posterior prensisetae. Ventral lobe with ca. 30 setae each one. Cerci microtrichose elongated, basely wider, with ca. 10 apical longer setae each one.

Female terminalia ( Fig. 5 View FIGURE 5 a–c). Cerci long and well sclerotized with 2 longer apical setae on each one. Epiproct with ca. 10 setae. Hypoproct with ca. 50 setae. Spermathecal capsule elongated with basal introvert reaching ca. 2/3 of inner capsule, length to width ratio = 1.56.
