Figs 3E , 5

Diagnosis

Vein R 1 setulose. Male: Scutellum with a pair of apical setae; vesica rectangular with an apical projection in lateral view ( Fig. 5C ); juxta smooth and recessed within paraphallus ( Fig. 5C–D ). [Female unknown.]

Etymology

The species epithet ‘ patiuorum ’ (‘ patiu ’ + ‘orum ’), a masculine plural genitive, is given in honor of the husband (Claudemir Patiu) and two sons (Fabio Patiu and Felippe Patiu) of the third author.

Material examined

Holotype BRAZIL • ♂; Mato Grosso do Sul, Rio Verde ; 18°09′39.4″ S, 54°09′02.4″ W; 30 Aug.–14. Sep. 2012; Lamas, Nihei and team leg.; Malaise trap; MNRJ [lost].

Description

Male (n=1)

Length: 8 mm. Differs from D. phoenix sp. nov. as follows:

Frons about 0.28 × head width at level of ocellar triangle; 10 well-developed frontal setae reaching level of apex of pedicel; first flagellomere approximately 4 × as long as pedicel; acrostichals 3 (weakly differentiated) +1; intra-alars 2+ 2, postpronotals 2; meral setae 7–8; vein R 1 setulose; row of about 10 marginal setae on T5; marginal setae of ST2–4 slightly differentiated from discal setae; surstylus almost triangular ( Fig. 5A ); pregonite 1.5× as long as postgonite, base narrow, apex broad and anterior margin dilated at middle ( Fig. 5C ); postgonite broad, with long seta inserted at middle of anterior margin ( Fig. 5C ); two longitudinal keels along posterior margin of basiphallus, and paraphallus with few short spines along ventral margin ( Fig. 5C ); vesica rectangular, with apical projection in lateral view ( Fig. 5C ); juxta smooth and recessed within paraphallus ( Fig. 5C–D ); median stylus robust, longer than lateral stylus and with base bent dorsally ( Fig. 5D ); lateral stylus with enlarged base slightly twisted towards ventral margin of paraphallus and with apical spines ( Fig. 5C–D ).

Female

Unknown.

Distribution

Brazil (Mato Grosso do Sul).

Remarks

Dexosarcophaga patiuorum sp. nov. is morphologically similar to D. guyi Mello-Patiu, 2000 by having basiphallus with two longitudinal keels and paraphallus with short spines ( Fig. 5C ; Mello-Patiu 2000: figs 4, 7). These two species can be differentiated by the following features: vesica rectangular, with an apical projection in lateral view ( Fig. 5C ), and paraphallus with short spines on ventral margin ( Fig. 5C ) in Dexosarcophaga patiuorum sp. nov., versus vesica triangular in lateral view and paraphallus with short spines on dorsal margin (Mello-Patiu 2000: figs 4, 7) in Dexosarcophaga guyi .
