Diagnostic description.

Length: 1.65-2.05 mm (avg. 1.89 mm); width: 1.50-1.77 mm (avg. 1.62 mm). This species is extremely similar to the preceding ( P. serratus ), but differs consistently in being broader in body form (Fig. 7E ), having the median portion of the frontal stria detached from the lateral portions rather than continuous across the frons, the pronotal disk more strongly depressed along the lateral margin, and in having sparser dorsal ground punctation, along with slightly lower density of secondary lateral pronotal punctures. The male genitalia exhibit no obvious differences from that of the P. serratus (Fig. 8C, D ).

Etymology.

This species name refers to its being a near twin of the preceding.

Distribution.

This species’ distribution broadly overlaps the preceding, covering much of northern South America. It does not extend into Central America, however, and records are very few in the Guianas.

Remarks.

As discussed under the preceding species, these are two very similar species, easily distinguished from all others by their unusual protibiae, but minimally different from each other. The description covers all characters that we have been able to find to distinguish them. We have restricted the type series to a relatively small number of localities in eastern Ecuador and Colombia, and northern Peru.
