Taxonomic notes.
We examined the type material of
Sadocus brasiliensis
and its external and penial morphology did not match that of other Chilean species of the genus. Based on its type locality, we examined other Brazilian
Pachylinae
genera and found striking similarities between
S. brasiliensis
and
D. catharinensis
. We examined detailed pictures of the type material kindly shared by Rafael N. Carvalho and additional material from the MZSP collection. Those species are the same, and we propose that
S. brasiliensis
is the junior synonym of
D. catharinensis
. Many
Discocyrtus
spp. have been transferred to revalidated genera or newly created subfamilies, such as
Roeweriinae
(
Carvalho and Kury 2018
) or
Neopachylinae
(
Carvalho and Kury 2021
). Indeed, the penial features of
D. catharinensis
(Fig. 15K, L) resembles those of that subfamily, which is corroborated in the present analysis:
D. catharinensis
is the sister species of
R. bittencourti
. Based on male genitalia and leg IV (see
Carvalho and Kury 2018
),
D. catharinensis
seems to belong to
Discocyrtanus
Roewer, 1929. However, because there is an ongoing study revising
Discocyrtus
conducted by Rafael N. Carvalho (MNRJ) and taking into account that it will have serious taxonomic consequences, we opted to propose only the synonymy of
S. brasiliensis
with
D. catharinensis
.
