( Figs 13View FIGURES 10 – 13, 18View FIGURES 14 – 19)

Diagnosis. Male cercus with long setae along the inner margin, cercal prong darker than cercal base and with a sharp-pointed tip (posterior view); distiphallus with vesica bearing two well-sclerotized lateral arms with a conspicuously pointed and curved apex, and juxta with two tongue-shaped and less sclerotized apical lobes. Female with epiproct as a tongue-shaped, setose plate, projected ventrally together with the cerci, T6 wide and setose, ST8 longer than wide, with round lateral depressions.

Redescription. Male. Length: 6–8 mm. Differs from R. sisbiota  sp. nov. as follows: parafacial and frontoorbital plates with very light golden pruinosity, posterior orbital area with silvery pruinosity; 7 well-developed frontal setae, gena and genal groove with light golden pruinosity; antenna with yellowish-brown pedicel and dark brown postpedicel; palpus brown; costal spine poorly differentiated; T5 with about 20 marginal setae; syntergosternite 7+8 with 4–6 strong marginal setae; cercal prong darker than cercal base, gradually tapering to a sharp tip; cercal prongs slightly divergent in posterior view; postgonite narrow, with a laterally-curved, slightly dilated apex; phallus brown; vesica with base arch-shaped and as two, well-sclerotized lateral lobes, projected toward the apex of the distiphallus, with a conspicuously pointed and curved tip; juxta apically split into two tongue-shaped and less sclerotized lobes (posterior view).

Female. Description in Lopes (1945: 452; as “ Paraphrissopoda setifacies  ”), here complemented by the following: epiproct as a tongue-shaped, setose plate, projected ventrally together with the cerci, T6 wide and setose, ST8 longer than wide, with round lateral depressions.

Remarks. This species is the most well-known and widely distributed species of Retrocitomyia  in South America in various biomes. Males were collected in the states of MT (Chapada dos Guimarães) and MS (Corumbá) in Cerrado and Pantanal habitats, respectively; these constitute new records for these Brazilian states and biomes. All specimens were collected in Malaise traps.
