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 .

Complementary description

ABDOMINAL TERGITE IX ( Fig. 7H ). Oval, asymmetrical, sides converging to anterior portion, forming long projection; left side more angulate them right side; inner anterior angle rounded, posterior portion rounded.

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.
