Comments.
In some genera of
Batrachideinae
and other genera of other subfamilies, limits are not clear, and it is usual that species in closely-related genera have been placed here, but they clearly not belong when reviewed more closely. This was the case, for instance, when
Hancock (1909)
, descry
Scaria brevis
based on a male specimen from Cachabi,
Ecuador
(
Fig. 6A and 6B
); and then
Hebard (1923)
described
Batrachidea inermis
based on a female specimen (
Fig. 7A and 7B
) from Andagoya,
Antioquia
,
Colombia
(currently this location is within the borders of
Chocó department
).
In all specimens reviewed of the genus
Scaria
no brachypronotal form was ever found, so we consider that in this genus, only macropronotal forms exist. On the other hand, in
Batrachidea
it is usual to find both macro and brachypronotal forms (sometimes in the same location along each other), which can give rise to confusions, as the macropronotal forms of
Batrachidea
, can superficially resemble
Scaria
and the brachypronotal ones could be mistaken for
Rehnidium
.
As for
Hebard (1923)
, females of
S. brevis
were unknown, he described
B. inermis
with females, but males of the same locality he unknowingly determined as
S. brevis
, not realizing that they are the same species. In
Batra- chidea
males and females are quite different from each other and it is often necessary to collect two in order to be certain of the association, unlike
Scaria
where males and females are very much alike. Hebard’s confusion spread up to the contributions of
Grant (1956a
,
1962
), who notes that the males of
B. inermis
remained unknown, but in the
Scaria
section of his thesis, he redescribes
S. brevis
mentioning also the lack of female specimens and adds the record of two additional males, one from, Muzo,
Boyacá
,
Colombia
, and other from Tingo Maria,
Peru
. It is worth mentioning that in Muzo and surrounding locales the only species of the family is
Batrachidea flavonotata
Bolívar, 1887
(as per field observations and collecting efforts by O. J. Cadena-Castañeda).

With this panorama expounded so far, it is suggested that
Batrachidea inermis
(
Hebard, 1923
)
syn. nov.
, is a synonym and conspecific female for
Batrachidea brevis
(
Hancock, 1909
)
comb. nov.
, and these latter fits charac- ters of
Batrachidea
better, not those of
Scaria
. These nomenclatural acts are performed upon reviewing the
type
specimens and additional ones collected, observed and photographed in the field (
Cardona, 2012
, pags. 114, 115 determined as
Scaria
sp.) and the collection of Filippo Maria Buzzetti as quoted by
Buzzetti & Devriese (2007)
.
