REMARKS

Sharing diagnostic characters with P. splendidus Hebard, 1923 (common species in Colombia, Cadena-Castañeda & Cardona- Granda 2015) and P.olivaceus Bruner, 1911 (the only species of the genus known from French Guiana). However, to be able to give a definite identification, a revision of the genus is needed. From P. splendidus it is differentiated by the shorter and thicker upper/dorsal protuberance of the male cerci and in the uniformly green color of the body. From P. olivaceus it is also differentiated by the shape of the male cerci being the dorsal/upper and lower/ventral protuberance equally long developed, and on the absence of long spines in the lower carina of the hind femur.
