Female
(
Figs 6–7
,
14
). Similar to males, differing especially by generic features (lateral setae on protarsus shorter and sparser; ventrite 5 longer than 3–4 together), and by antennae shorter, 1.95 times elytral length, reaching elytral apex at basal third of antennomere VII (antennae measured only in a
paratype
female).
Chromatic variations in the
paratypes
.
Antennae mostly darker; ventral surface of meso- and metathorax blackish. As in
Colobothea hirtipes
(Degeer; 1775), the dark elytral areas present in the large anterior maculate region (such as ocelli) are sometimes absent.

Note
: In 2010, the first author was a reviewer of the work by
Monné & Monné (2010)
, on the species of
Colobothea
from
Bolivia
. During the review, it was noted that the authors were illustrating a specimen as being
C. hirtipes
. In fact, this specimen belonged to the new species described herein. In the published work, the authors have changed the figure, illustrating a true specimen of
C. hirtipes
. Therefore, we are sure that
C. batesi
sp. nov.
is present in the Bolivian fauna. Its presence in the Amazon region may follow the wide distribution of its host plant of the genus
Machaerium
.

Etymology and notes.
In honor of Henry Walter BATES who described 59 species of
Colobothea
, with 50 valid species in a very difficult group. He was a very accurate entomologist who spent 11 years collecting in the Amazon region and was the first to see the difference between
C. hirtipes
and
C. batesi
. Unfortunately, he did not see the
type
of
Colobothea contaminata
Audinet-Serville. Gounelle
, in his collection, had labeled
one male
collected in
French Guiana
(Saint-Jean du Maroni) sold to him by Eugène Le Moult as “
contaminata sensu
Bates
,
nec
Audinet-Serville.” Both ignored that
C. contaminata
was a junior synonym of
C. hirtipes
,
C. annulata
Fabricius
, and
C. lineata
Fabricius.
This was elucidated when Maxwell Barclay (BMNH) sent to the first author the picture of a
type
of
C. contaminata
in 2010.
Remarks.
Colobothea batesi
sp. nov.
is similar to
C. hirtipes
(De Geer, 1775)
, and differs by the humeral shape: rounded projected in the former (
Figs 13–14
); straight and not projected in the latter (
Figs 15–16
). Although we only observed one difference, it is conspicuous and allows us to easily separate the two species. Furthermore, we have access to over 70% of the known species and did not find this difference in any of them. Even in the species of which we have large series of specimens, no variation in humeral shape was observed as, for example:
C. schmidtii
Bates, 1865
(about
100 specimens
);
C. seriatomaculata
Zajciw, 1962
(about
80 specimens
);
C. poecila
(Germar, 1823)
(about
60 specimens
);
C. rubroornata
Zajciw, 1962
(about
60 specimens
);
C. emarginata
(Olivier, 1795)
(about
80 specimens
);
C. fasciata
Bates, 1865
(about
50 specimens
);
C. flavoguttata
Aurivillius, 1902
(about
40 specimens
);
C. musiva
(Germar, 1823)
(about
100 specimens
);
C. naevigera
Bates, 1865
(about

);
C. cassandra
(Dalman, 1823)
(about

);
C. brullei
Gahan, 1889
(about
30 specimens
). Even in
C. discicollis
Gahan, 1889
, a species with the humerus identical to that in
C. hirtipes
, no variation was observed in over
20 specimens
. As the new species and
C. hirtipes
occur in the same region, at least in
French Guiana
and
Brazil
, the hypothesis of it being a subspecies can be disregarded.
