Ligocatinus olivaceus
(Brunner von Wattenwyl, 1891)
Ligocatinus borellii
(
Giglio-Tos, 1897
)
syn. nov.
Phaneroptera quadrivittata
Piza, 1967
syn. nov.
The male
holotype
from south-eastern
Brazil
and a subsequently collected female from southern
Brazil
(labeled as not-described allotype) are misplaced in
Phaneroptera
, a genus with wide distribution in the Old World (
Ph. nana
, a species recently introduced to California, is the only other
Phaneroptera
species recorded in the New World). The two specimens actually look like typical members of the neotropical genus
Ligocatinus
, and are very similar to
L. olivaceus
(Brunner von Wattenwyl, 1891) from southern
Brazil
and
L. borellii
(
Giglio-Tos, 1897
)
from southern
Bolivia
and northern
Argentina
. Piza’s male coincides in many habitus and coloration details with the male
syntype
of
L. olivaceus
(photos in OSF). The cerci seem to be a little longer. This would be diagnostic for
L. longicercata
from south-eastern
Brazil
(no images available), which was described in the paragraph preceding the descriprion of
L. olivaceus
. The other difference between the two species mentioned in Brunner’s (1891) key, is that the hind femora in
L. longicercatus
are by a third shorter than the tegmina (in male 18 vs.
29 mm
), in contrast to only a little bit shorter in
L. olivaceus
(in male 16 vs. 20.5 mm). The measurements in Piza’s male (14 vs.
19 mm
) are much closer to
L. olivaceus
. In combination with the near perfect agreement with the photos of
L. olivaceus
, we consider
Phaneroptera quadrivittata
identical with that species. Furthermore,
L. borellii
must the same species as well, since no differences are discernible (photos of a male and a female
type
in OSF; measurements of male hind femora and tegmina 17–18 vs.
18–20 mm
). The male labeled as
lectotype
(designation apparently unpublished) shares with Piza’s male the yellowish pattern on the abdominal tergites, and also the cerci are very similar. For a phanteropterine tettigoniid with well-developed wings, which facilitate dispersal, the geographical records in
Brazil
,
Bolivia
and
Argentina
should be close enough, assuming that the ones from the latter two countries refer to lower elevations in the eastern Andean foothills of Potosí department and Jujuy province.
