Etymology.
The epithet, to be treated as a noun in apposition, is a word used in
Brazil
for black water flooded forest in the Amazon, since the specimens reported here were collected from that habitat.
Diagnosis.
Males of this species can be recognized by having the embolus with no abrupt angle (
Fig. 44
) (in
E. simoni
, the embolus extends straight distally and then forms an angle at its middle; see
Fig. 11
). Also, males of
E. igapo
sp. nov.
have larger terminal apophysis and smaller RTA (
Fig. 44
). Females of
E. igapo
sp. nov.
have round copulatory openings, the spermathecae are larger and the dorsal coupling pocket is not centralized, almost paired (
Figs 43
,
48–49
).

Biology.
According to
Adis (2002: 8)
, the
type
locality is covered with a clayish-sandy soil, being inundated for about four months every year, which agrees with the description of the locality in Belém where
E. simoni
is found. This seasonal
igapó in Manaus
has been periodically flooded for at least one million years.
Distribution.
Known only from
type
locality.
