Redescription. Male ( Figs 12 , 17 ). Length: 7–8 mm. Differs from R. sisbiota sp. nov. as follows: 7 frontal setae, outer vertical seta slightly longer than postocular setae, palpus brown, T5 with about 20 marginal setae, syntergosternite 7+8 with 7 strong marginal setae, cercal base wider than apex, with numerous long setae along the inner margin, cercal prong with a cluster of long setae at the base and short setae at the apex (posterior view, Fig. 17 ); vesica simple, consisting of two rounded lobes joined at their bases; juxta conspicuous, base medially projected, subtriangular in postero-apical view, apically with a cleft forming two, rounded lateral lobes with apex bent laterally.

Female. Unknown.

Material examined. Holotype ♂: “ Paraguay, Chaco-i [small community near Asunción on the left margin of River Paraguay, 25°15'0”S 57°38'0”W] / 6[= vi].1944, Mis. Cient . Brasil col. [Missão Científica do Brasil leg.] [printed on white paper]” // “Holotype [printed on red paper, black frame]” // “ Retrocitomyia ♂ / paraguayensis n. sp. / Holotypus [handwritten on white paper] / Det. H.S.Lopes [printed]” // “MNRJ 2275 [printed on white paper]” (MNRJ). Other material—BRAZIL, Mato Grosso: Chapada dos Guimarães, 15º26’10.7”S 55º47’22.9”W, Vale da Benção / forest, hand net, 19.i.2012, Lamas, Nihei et al. leg., 2 ♂ (1 MNRJ, 1 MZUSP) ; Poconé, Fazenda Rio Clarinho , van Sommeren trap, artificial bait, 16.vii.2012, Patiu & Patiu leg., 1 ♂ ( MNRJ) .

Remarks. Only three males of this species were collected from the state of MT in riparian forest areas of Cerrado and Pantanal. These specimens were identified by comparison with the holotype and represent the first record of this species from Brazil. The specimens were attracted by using an artificial, feces-scented bait used in livestock pest control.
