Mecistogaster fililigera
Rambur, 1842 Syn.
Mecistogaster flavistigma
Rambur, 1842 Syn.
Diagnosis.
Very large species (♁ HW 49-60, abdomen 100-125). Color black, ventrally pale yellow. Face dark brown. Pterothorax with two humeral yellow stripes originating on opposite sides, the anterior reaching the anterior border but not the sinus, the posterior reaching the sinus but not the anterior border. Venter surrounded by black with a median black stripe. Hindwing with anterior border not angulated at level of pseudostigma. Pseudostigma in mature specimen black, extending to the cell row below it. S10 slightly elevated and excavated. Cercus in dorsal view spatulated, in lateral view straight.
Remarks.
The diagnosis above was based in
Selys (1860
,
1886
) according to whom the male specimens agree with the specimen in the collection of Banks in the British Museum, believed to be labeled by Fabricius. According to
Calvert (1948)
this male is the
lectotype
of
M. linearis
.
Also,
Bridges (1994)
regards this specimen as the type of Fabricius
M. linearis
. However,
M. linearis
is not mentioned in the list of type specimens of the British Museum published by
Kimmins (1970)
.
Mecistogaster linearis
has a very large distribution that according to
Tsuda (1991)
comprises
Bolivia
,
Brazil
,
Colombia
,
Ecuador
,
Peru
and
Venezuela
. In
Brazil
it comprises Amazonian States,
Rio de Janeiro
and
São Paulo
. The record in
São Paulo
(Jacareí) was obtained by
Lencioni (2017)
and the record for
Rio de Janeiro
was obtained by Janira Costa (

) and both are represented in the map (
Fig. 2
).
