Lacosoma ostrinum
Herbin, 2016
(
Figs. 21, 22
)
Type
locality.
French Guiana
Like
Druentica
,
Lacosoma
consists of many similar taxa, and is in dire need of an adequate revision. However, the genitalia dissection of the single male
Lacosoma
(other than
L. valva
) in
Trinidad
is a very close match to the genitalia of the
holotype
of
L. ostrinum
(
Herbin 2016, figs. 90–92
). Externally, these specimens are quite close as well, although the forewings are slightly more falcate in the
holotype
of
L. ostrinum
. If our determination is correct, this is the first report of
L. ostrinum
outside of
French Guiana
.
Although we have only examined a single pair of specimens from
Trinidad
, we have no reason to believe that they are not conspecific considering the scarcity of
Lacosoma
collected in
Trinidad
. Therefore, we figure here the female of
L. ostrinum
for the first time. Both
Trinidad
specimens were captured in lowland forest, the male in the south and the female between the
Northern
and
Central
Ranges.
