Male: scutellum with a pair of reduced apical setae; vesica like a small sclerotized plate ( Fig. 9D–E ); juxta like a narrow band ( Fig. 9D–E ). Female: the two halves of T8 widely separated by at least four times the width of cercus, each half pointed in its median part ( Fig. 10A–B ). Etymology The species epithet ‘ sphaera ’ should be treated as a noun in apposition. The name is a Latin noun ‘ sphaera ’, meaning ‘ball’ and alluding to the spherical paraphallus.

Abbreviations: see Material and methods. Scale bars =0.1 mm. Description Male (n=7) Length: 6–9 mm . Differs from D. phoenix sp. nov. as follows: Frons about 0.18 × head width at level of ocellar triangle; 7–10 well-developed frontal setae reaching level of apex of pedicel; gena and genal groove with slightly yellowish-silver pollinosity ( Fig. 8B ); first flagellomere approximately 4× as long as pedicel; thorax with slightly yellowish-silver pollinosity ( Fig. 8B ); intra-alars 2+2; meral setae 8–11; scutellum with pair of reduced apical setae; abdomen dark brown, with slightly yellowish-silver pollinosity ( Fig. 8B ); T4 with 2 pairs of lateral marginal setae; row of about 12 marginal setae on T5; inner margin of ST5 without lobes or an incision but with elongate pad-shaped protrusion ( Fig. 9A ); cercal prong rounded in lateral view ( Fig. 9B ); surstylus almost triangular ( Fig. 9B ); pregonite as long as postgonite ( Fig. 9D ); postgonite with long seta inserted near the slightly dilated anterobasal corner ( Fig. 9D ); vesica in lateral view in shape of small sclerotized triangular plate ( Fig. 9D–E ); juxta like narrow band ( Fig. 9D–E ); median stylus narrow, as long as lateral stylus ( Fig. 9D–E ); lateral stylus with base expanded towards ventral margin of paraphallus and equipped with spines apically ( Fig. 9D–E ).

Terminalia, ventral view. C . Spermatheca, lateral view. Abbreviations: see Material and methods. Scale bars=0.1 mm. Female (n =4) Length: 6–9 mm ; frons about 0.29 × head width at level of ocellar triangle; scutellum without apical setae; T5 with 10 marginal setae; T8 divided into two large and bare halves, widely separated by at least 4 × as wide as cercus, each half pointed in its median part ( Fig. 10A–B ); ST2–5 with one pair of long setae ( Fig. 10A ); ST5 almost square ( Fig. 10A ); ST6–8 fused ( Fig. 10A–B ); ST7 about 2× as long as ST6 ( Fig. 10A–B ); ST8 rounded ( Fig. 10A–B ); epiproct membranous, without setae ( Fig. 10A–B ); vaginal plate sclerotized ( Fig. 10A–B ). Distribution Brazil ( Distrito Federal , Minas Gerais , Pernambuco , Roraima ). Remarks Dexosarcophaga sphaera sp. nov. is similar to D. globulosa Lopes, 1946 . Males of both species have paraphallus with a pointed projection on distal half and juxta like a narrow band ( Fig. 9D–E ; Mello 1996 : figs 16, 18). These two species can be differentiated by the following features: postgonite with long seta inserted near a slightly dilated region in anterobasal corner ( Fig. 9D ), vesica short ( Fig. 9D– E ), and elongated lateral and median styli ( Fig. 9D–E ) in D. sphaera sp. nov. , versus postgonite with long seta inserted near a slightly dilated region in anteroapical corner ( Mello 1996 : figs 13–14), vesica conspicuous ( Mello 1996 : figs 16–17), and short lateral and median styli ( Mello 1996 : figs 16, 18) in D. globulosa .
