20 specimens

: Instituto
de Biociências, Universidade de São Paulo on
Hibiscus
sp., collected in April, 2013;
paratype
female from Mercedes, Texas,
USA
, on corn leaf, collected in May, 25, 1955.

An evaluation of the measurements provided in the literature for

Moraes & McMurtry, 1983
) and
E
.
brazilli
(
El-Banhawy, 1975
)
, as well as an examination of a
paratype
of
E
.
mesembrinus
and additional specimens of the same species collected in Florida, of the
holotype
of
E
.
ho
and specimens of
E
.
brazilli
collected in its
type
locality, showed that the latter two species are junior synonyms of
E
.
mesembrinus
.
The length and width of the dorsal shield shown in the original description of
E
.
brazilli
are considerably larger than the measurements obtained in this study for the
paratypes
and for females collected in the
type
locality of the species. Probably the measurements given in the original description refer to the length and width of the idiosoma. Other characteristics contained in the original description and observed in specimens examined in this study are very similar.
