Martins & Galileo (1992)
described
Juninia beckeri
based on a single female from
Costa Rica
(
Cartago
). According to them (translated): “The separation of the males of the species of
Purusia
and
Juninia
is immediate: the frons in
Purusia
is strongly projected and in
Juninia
regularly convex, without projections. Since the frontal projections, that occur in several genera of this tribe, are a secondary sexual character, the distinction between females of
Juninia
and
Purusia
is still difficult. We do not know females of
J. leechi
, but we have a female of
P. acreana
in our hands. The shape of the elytral apex and the color pattern led us to describe
J. beckeri
in
Juninia
.” When they received a male of the species,
Martins & Galileo (1993)
described
Sibapipunga
to include
Juninia beckeri
, which has two large tubercles on frons. In the description of the genus, they only noted that the humeral carina is prolonged to the apical quarter. As seeing before, according to
Martins & Galileo (2014)
,
Sibapipunga
would have only the humeral carina, lacking another lateral carina. However, although very close to the humeral carina, there is a second carina in male (
Fig. 24
) and female (26).
Martins & Galileo (1993)
recorded
S. beckeri
for
Ecuador
and Martins & Galileo (2004) examined a female from
Colombia
.
In the male of
S. beckeri
, the humeri are distinctly projected, while they are not so in female, the outer apical angles of the elytra are distinctly more projected than in the female, and the antennae are much longer.
The tarsal claws in the female (
Fig. 27
) and male (
Fig. 28
) are similar, with the inner tooth noticeably widened basally. However, the inner tooth in the male is considerably shorter than in the female.As we had only one pair, we do not know if the length of the inner tooth is variable between the sexes.
