Derivatio nominis. This species name, ecuadorensis, is derived from Ecuador, where this species was collected.
Comment. P. ecuadorensis differs from P. colombiensis in the absence of: spiniform setae and sensory organs on antennal intersegmental membrane; in the arrangement of the dorsal hair-like setae and hairs; and in the presence of: circular or broadly oval multilocular pores, each with an oval, triangular, quadrate and pentagonal centre; more numerous, broadly oval, multilocular pores, and the greater number of perispiracular pores of thoracic spiracles.
