( Figs. 11 , 23 )

Sarcophaga paulistanensis Mattos, 1919: 72 .

Oxysarcodexia amarali Prado & Fonseca, 1932: 35 . Oxysarcodexia delpontei Blanchard, 1939: 809 . Oxysarcodexia artigasi Dodge, 1966: 684 .

Distribution: Neotropical – Argentina (Buenos Aires, Córdoba, Entre Ríos, Mendoza, Tucumán), Brazil (Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul, São Paulo), Chile (Santiago).

Lectotype designation. Blanchard (1939: 809) described Oxysarcodexia delpontei from an unknown number of specimens (as “cotipos”) from Córdoba, Buenos Aires and Delta del Paraná, all in Argentina . We located one male syntype from Buenos Aires and eleven female syntypes from Delta del Paraná in MACN. The male syntype is hereby designated lectotype of Oxysarcodexia delpontei Blanchard, 1939 in the interests of nomenclatural stability. Lectotype male (MACN): in perfect condition, pinned, terminalia dissected on two cover slips pinned below the specimen. Label: “Bs As. [Buenos Aires] / prep. EB 2 [white label, handwritten]”. Paralectotypes 11 Ψpinned. Labels: “Delta / VI-38 [white label, handwritten] // Oxysarcodexia / delpontei / Blnchd. / det E.E. Blanchard [white label, black square, handwritten]”.

Remarks: Good illustrations of male terminalia were provided by Blanchard (1939), Lopes (1946a), and Dodge (1966). The female terminalia were illustrated by Tibana & Mello (1985).

Biology: The seasonal abundance of this species was described by several authors from different geographic locations where O. paulistanensis is found throughout the year ( Ferreira 1979; Linhares 1981; Dias et al. 1984b; Mendes & Linhares 1993; Mulieri et al. 2008). Moreover, O. paulistanensis showed a wide range of habitat preferences such as urban areas ( Ferreira 1979; Linhares 1981; Dias et al. 1984a) or grasslands and woodlands of natural areas ( Mariluis et al. 2007; Mulieri et al. 2008). This species was captured on faeces and rotten animal tissues ( Ferreira 1979; Linhares 1981; Dias et al. 1984c; Mariluis et al. 2007; Mulieri et al. 2008), and was reared on rat carcasses ( Moura 2004). Flower visitor of Apiaceae ( Coriandrum sativum ), Rhamnaceae ( Condalia spp., Discaria americana , Scutia buxifolia ).
