Remarks.
Júlio (1997)
compared
O. laetus
with
O. ruficollis
(
Zajciw, 1964
)
. However, the species appears to be more similar to
O. brasiliensis
(
Tippmann, 1953
)
. Comparing the photographs of the
holotype
male of
O. laetus
and
O. brasiliensis
(wrongly described as a female, see
Zajciw (1964)
and
Martins & Galileo (2003))
, the most reliable difference appears to be the length of the antennae: longer in males of
O. brasiliensis
(the antennae extend about a third of their length beyond the body –
Tippmann (1953))
than in
O. laetus
(antennae surpassing elytral apex by the two last antennomeres –
Júlio (1997))
. Unfortunately, the
holotype
and
paratypes
of
O. laetus
, as well as the
holotype
of
O. brasiliensis
were destroyed during the fire in 2018 at the MNRJ.

Paratype female, dorsal habitus;

Paratype female, ventral habitus;

Paratype male, dorsal habitus;

Oxymerus laetus
Júlio, 1997
, female from Brazil (Mato Grosso):
36)
Dorsal habitus;
37)
Ventral habitus.
Júlio (1997)
also reported on the elytra (translated): “elytral carina restricted to a short shining area on apical 1/6.” However, the
two females
examined by us have no elytral carina even on the apical area.
