Dexosarcophaga itaqua Dodge, 1966: 681. Type locality: Brazil, São Paulo, Itaquaquecetuba; male holotype, USNM.
Male – Total length = 6 mm.
Head – Fronto­orbital and parafacial plates gray with golden microtomentum, with a row of black setulae along eye margin; frontal vitta dark brown; frons 0.22 X head width; frontal row of 9 bristles; 1 reclinate fronto­orbital bristle, proclinate absent; outer vertical bristle not differentiated from the postocular setae; gena and postgena gray with black setae; antenna dark brown [first flagellomere lost in the holotype], palpus dark brown with black apex.
Thorax – Gray, postpronotal lobe with golden microtomentum. Proepimeron bare; prosternum with sparse setae. Chaetotaxy: acrostichals 3 (weakly differentiated) + 1, dorsocentrals 3 + 4 (two posterior longer), intra­alars 1 + 2, supra­alars 2 + 3, postpronotals 3, postalars 2, notopleurals 4, scutellum with 2 marginals bristles intercalated by 2 weak ones, apical absent, discals 1, meropleurals 6, katepisternals 3 (in a line). Wing hyaline, R1 bare, R4+5 setulose in basal 2/3 to crossvein r­m, costal spine not differentiated, third costal sector without ventral setulae. Legs black, mid femur apically with posteroventral ctenidium (6­7 spines), mid tibia with 1 median postero­dorsal bristle, without ventral setae, hind tibia with 1 antero­ventral median setae.
Abdomen – Black with the usual pattern of silvery gray microtomentum; T1+2–3 without median marginal bristle, T4 with a row of marginal bristles; ST1­2 with long black hair­like setae.
Terminalia – Syntergosternite 7+8, epandrium and cercus black with sparse gray microtomentum; epandrium with some differentiated dorsal bristles and syntergosternite 7+8 with 3 pairs of bristles in the row of marginals (Fig. 1); cercus moderately curved forwards in profile (Figs. 1­2); surstylus clavate with elongated apical setae (Fig. 1); gonopod with slightly enlarged base (Figs. 3, 4) and paramere gently curved and with a strong median bristle on anterior margin (Figs. 3, 5); phallus with a distinct basiphallus and a deep concavity between the apex of distiphallus and juxta (Figs. 3, 6); juxta narrow, protecting the apices of lateral styli (Figs. 3, 6, 7); lateral stylus long with simple base and dentate apex (Figs. 6, 7); median stylus represented by a small, double, rugose lobe between the apices of the lateral styli (Figs. 6, 7); vesica well sclerotized, bearing a pair of median apophyses laterally, bifurcated at apical portion with divergent arms (Figs. 6, 8).
Female – unknown.
Material examined – Brazil. São Paulo: Itaquaquecetuba, 1 male (holotype), V. 1929, Townsend (USNM).
Distribution – NEOTROPICAL – Brazil (São Paulo).
Remarks – This species is very similar to D. transita and D. lopesi, but can be distinguished specifically by the presence of median apophyses and divergent broad apical arms in the vesica (Fig.8). The ST5 was not dissected due to the fragility of the holotype.
