Remarks: The male terminalia of S. lambens are well recognized. Good illustrations of the males can be found in Aldrich (1916), Engel (1931), Blanchard (1942a) and Shewell (1987). The female terminalia were described and illustrated by Lopes (1974) on the basis of the holotype of Sarcophaga innota described by Walker.

Biology: In Brazil, this species showed higher abundance during the warmer months (Linhares 1981). Sarcodexia lambens is regarded as an urban avoider species (Ferreira 1979; Linhares 1981; Dias et al. 1984a). This species also showed a wide range of food preferences and was captured with several kinds of baits (Ferreira 1979; Linhares 1981; Dias et al. 1984c), or reared from carrion, dead invertebrates, or living insects (as a facultative parasitoid) (Lopes 1973c; Blanchard & De Santis 1975; D’Almeida 1988, 1989, 1994; Coupland & Barker 2004). Host. Gastropoda, Bulimulidae: Plagiodentes meieri Weyrauch, P. multiplicatus (Doering), Spixia juradoi Parodiz and S. pseudosexdentatus Doering (Lopes 1969b) . In addition, S. lambens was recorded as a myiasis-causing species on domestic animals and humans (Neiva & Faria 1913; Guimarães et al. 1983).
