Remarks: Engel (1931) illustrated the male terminalia. Later, Lopes (1976) and Guimarães (2004) redescribed the male copulatory apparatus with the inclusion of good and interpretative drawings. Illustrations of female terminalia were provided by Lopes (1976).

Biology: In Brazil this species shows higher abundance during the winter, a strong association with wild and non-urbanized areas, and coprophilous habits (Ferreira 1979; Dias et al. 1984a, b, c,). In addition, R. advena was reared from cattle dung by Mendes & Linhares (2002).
