Type material.

Holotype female: " Peru: Dept. Cusco: Cock of the Rock Lodge, NE Paucartambo 13°03.3'S, 71°32.7'W 1120 m, 4-9-XI-2007, D.Brzoska, ex. Flight intercept trap, PER1B07 001" / "SEMC0870736 KUNHM-ENT" (SEMC).

Diagnostic description.

Length: 2.25 mm; width: 2.05 mm. This species is extremely similar to the preceding, and differs in only a few unusual characters: body larger; median pronotal gland openings nearer halfway back from anterior margin; frontal stria obsolete in median depression, frons with distinct microsculpture; antennal club with two distinct dorsal and one ventral setal sensory patch basal to elongate median patch (Fig. 11C ); propygidium more coarsely and densely punctate; protibia slightly broader; lateral metaventral stria divergent toward mesepimeron. Male not known.

Etymology.

This species name, tunki, is the local name of the Andean cock-of-the-rock ( Rupicola peruvianus ), a beautiful and popular bird in the area, for which the lodge at the type locality was named.

Distribution.

This species is only known from the type locality, Cusco, Peru.

Remarks.

Although this species is known only from a singleton, from a locality on the margin of the range of its closest relative P. sculpturatus , there are enough clear morphological differences between the two to support its separate species status.
