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
).
