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).

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 .
