Biology. Fannia obscurinervis is a synanthropic species ( Oliveira 1986 ; de Carvalho et al. 2002), collected in rural areas ( Almeida et al .1985 ), and also in forests (de Carvalho & Couri 1991 ). It is associated with carrion ( Linhares 1981 ; Moura et al. 1997 ), decomposing onions, chicken liver, sardines ( Almeida et al. 1985 ), chicken guts, human faeces ( Linhares 1981 ), decomposing shrimp and banana (Wendt & de Carvalho 2009 ). Comments. F. obscurinervis was redescribed by Albuquerque (1946) . He also described the female, and illustrated the legs and terminalia of male and female. Wendt and de Carvalho (2009) recorded the species in southern Brazil , re-described it and made new drawings for it. Fannia obscurinervis belongs to the group obscurinervis ( Albuquerque et al. 1981 ) , however, the monophyly of the group has not been corroborated ( Domínguez & Roig-Juñent 2008 ).
