Brassolis dinizi
d’Almeida, 1956
,
NEW STATUS
(
Fig.

I–J, 7A, 9E)
Diagnosis:
Recognized by a combination of seven characters: (1) small size (male FW length 53.3 – 62.5 mm); (2) in both sexes, dorsal background coloration ashen brown; (3) in both sexes, ventral surface of both wings markedly pale and contrasting a diffuse dark area proximal to the FW postmedial band, below the discal cell; (4) in males, dorsal FW postmedial band completely white above Cu1, with a pale orange tinge posteriorly, usually below Cu1 (
Fig. 7
A, character 12:0); (5) in females, dorsal FW postmedial band nearly bifurcated into two branches at the distal edge of the discal cell (
Fig. 2
J); (6) in both sexes, dorsal HW postmedial band pale orange and well defined; (7) in both sexes, abdomen faded orange dorsally.
Distribution:
Northeastern
Brazil
(d’Almeida 1956).
Justification for new status:
It is likely that d’Almeida (1956) considered
dinizi
a subspecies of
B. sophorae
because it has a well-defined HW postmedial band. However, when compared to
B. sophorae
from several localities across its range (Appendix 1,
Fig. 2
),
B. dinizi
shows a distinctively pale dorsal and ventral coloration, nearly completely white male FW postmedial band, and smaller wing-length. In combination, characters listed above provide a positive and reliable diagnosis for
dinizi
. Furthermore, the tree in
Fig. 4
A shows four character changes for this species; a number comparable to
haenschi
, and larger than what was found for other
Brassolis
. While
dinizi
can be clearly distinguished from
sophorae
, other
Brassolis
species are more difficult to separate (e.g.,
isthmia
and
granadensis
). Therefore, based on the diagnostic characters listed here, we propose a change in the taxonomic status of
dinizi
from subspecies to species.
