Vairo, Karine Pinto e, Moura, Mauricio Osvaldo & Mello-Patiu, Cátia Antunes de, 2015, Comparative morphology and identification key for females of nine Sarcophagidae species (Diptera) with forensic importance in Southern Brazil, Revista Brasileira de Entomologia 59 (3), pp. 177-187 : 186

Microcerella halli (Engel, 1931) ( Figs. 9 , 11F , and 12H )

Description – differs from male in the following: two proclinate orbital setae well developed; no row of small and strong setae on anteroventral part of trochanter 3; tibia 2 with tree anterior setae and presence of a reddish sensorial area on posterior part of femur. Tergite 5 black with silver microtomentum. Tergite 6 undivided; reddish brown to orange, contrasting with the dark tergite 5; spiracle 6 in membrane and spiracle 7 within the sclerite; 20–24 strong marginal setae accompanied of small ones. Tergite 7, tergite 8 and epiproct absent. Sternites 1–5 reddish brown, darker than the others; sternites 2–6 squared shaped with a row of strong setae on posterior margin; sternites 6, 7 and 8 fused; sternite 6 wider and shorter than the sternite 5; sternite 7 quadrangular; central surface slightly depressed relative to the posterior margin, without setae; sternite 8 swollen, widely membranous except for the sclerotized posterior margin, posterior angles expanded with three apical setae each. Vaginal plate absent or probably completely membranous and not apparent. Spermatheca divided into two parts by a constriction, a narrow and cylindrical proximal part and a rounded distal one, less striated than the proximal and 2.0 times its width.

Distribution: Argentina (no further data), Bolivia, Brazil (Ceará, Minas Gerais, São Paulo, Paraná, Rio Grande do Sul).

Material examined: 10 females from colonies initiated by specimens collected in Brazil, Paraná, Curitiba , vi. 2011. K. Vairo col.

Sarcophaga (Bercaea) africa (Wiedemann, 1824) ( Figs. 10 , 11I , and 12I )

Description – differs from male in the following: two proclinate orbital setae well developed; inner vertical setae differentiated of postocellar setae. Tergite 5 with golden microtomentum more conspicuous in lateral view. Tergite 6 divided into two plates well separated and dorsally folded; spiracle 6 in membrane and spiracle 7 within the sclerite; 15–16 strong and long marginal setae. Tergites 7 and 8 absent. Epiproct represented by two small dorsal plates without setae. Sternites 2–4 squared shaped with posterior margin rounded; two strong setae in each angle of posterior margin; sternite 5 quadrangular with strong marginal angular setae. Sternites 6, 7 and 8 fused; Sternite 6 almost two times wider than sternite 5, with a medially interrupted row of setae on posterior margin; sternite 7 with a noticeably elevated central area; sternite 8 like a narrow and swollen range fused with the posterior margin of sternite 7, with two lateral groups of setae, two strongest setae and many setulae. Vaginal plate well sclerotized, darker than the sternites, and very long, from the hypoproct to the middle of sternite 6 with a median suture. Spermatheca oval and slightly elongated with transversal striations in all surfaces.

Distribution: Argentina (Buenos Aires), Brazil (Rio de Janeiro, Paraná, Rio Grande do Sul), Costa Rica, Cuba, Mexico, Paraguay.

Material examined: 10 females from colonies initiated by specimens collected in Brazil, Paraná, Curitiba , viii. 2012. K. Vairo col.
