Notes
The new record is from the same biogeographical dominion, the South Brazilian dominion, but from the Madeira province, while the
holotype
is from the
Rondônia province
. In
Straneo & Ball (1989)
the authors synonymized four species (
P. cyanipes
,
P. carinatum
,
P. ovipenne
and
P. humeratum
) and divided
P. cyanipes
into four “morphs” (
cyanipes
morph,
carinatum
morph,
ovipenne
morph and
humeratum
morph). All specimens of
P. cyanipes
examined by us fit in the
humeratum
“morph”. Comparing the examined specimens with photographs of the
holotype
of
P. cyanipes
and the “morph” descriptions, we noted morphological differences that are sufficient to question the aforementioned synonymies, such as body shape and head frontal fovea. However, in order to review the species limits, it is necessary to examine the
holotypes
of
P. carinatum
,
P. ovipenne
and
P. humeratum
.

AEDEAGUS
(
Fig. 7F–G, I–J
). With
median lobe
(
Fig. 7F–G
) cylindrical, asymmetrical, bent to left, slightly broadening apically; ostium short, confined to apical fourth; apical lamella long, apical edges narrow; basal bulb thin.
Parameres
(
Fig. 7I–J
) asymmetrical; left paramere elongate, posterior angle rounded; right paramere square, with protuberant rounded lateral angle.
GONOCOXITE
1 (
Fig. 7K
). Outer and inner sides arcuate; inner side forming acute projection on posterior margin; anterior margin dull.
GONOCOXITE
2 (
Fig. 7K
). Short; basal lobe bearing ensiform setae on each side; ensiform setae very short, with one-fifth to one-sixth the length of gonocoxite 2; slender setae at apex.
