Rhinoleucophenga specimens determined by Costa Lima (1935) as R. obesa

( Figure 2 a–c; Table 2 )

Examined Material: A female labeled “ R. obesa . Tube N° 1085/2116, specimen N° 2419”. A male specimen with the terminalia disarticulated labeled “ R. obesa . Tube N° 1085/2116, specimen N° 2419”.A wing in a slide numbered as 2365. Specimens from Deodoro, Rio de Janeiro, RJ, Brazil. All specimens are deposited in the Coleção Entomológica do Instituto Oswaldo Cruz ( CEIOC)/ Fiocruz.

Diagnosis. General body color brownish; front covered with ca. 200 scattered interfrontal setulae. Frontal index 1.87 (1.75–2.00); Carina nose-like and sulcated along ca. 90% of the length of praefrons; arista with 9 long dorsal branches and 7 long ventral branches. Wings with cloudy spots. Body length ca. 5.00 mm.

Description. Head ( Fig. 2c ). Front ventrally brownish and superiorly yellowish, covered with ca. 200 scattered interfrontal setulae; ocellar triangle yellowish (or brown in some specimens) with dark brown ocelli. Carina noselike and sulcated along ca. 90% of the length of praefrons. Face yellowish; gena brownish; antenna with flagellomore and pedicel homogeneously brownish; arista with 9 long dorsal branches and 7 long ventral branches. Palpus brownish with ca. 50 (40–60) setae on lower part.

Thorax ( Fig. 2 a–b). Scutum brownish (with diffuse brown stripes in some specimens) and scutellum homoge- neously yellow. 12 irregular rows of acrostichal setulae. Three pairs of prescutellar acrostichal setae. Pleura yellow- ish; halteres yellow-brownish. Legs homogeneously yellow.

Wings ( Fig. 2a ). Non-hyaline, with distal and proximal cloudy spots. Vein dM-Cu and R-M clouded.

Abdomen. Abdomen all black (color probably not properly preserved).

Terminalia. Probably the aedeagus and epandrium depicted in Costa Lima (1950) belonged to the dissected specimen. The terminalia were not located.
