Description. Male
holotype
.
Length
2.3 mm
, width
2.1 mm
; dorsal surface shiny except head densely alutaceous. Color black; pronotum with lateral 1/4, apical 1/4 yellow; elytron with wide, yellow lateral margin enlarged into incipient macula on apical declivity, in addition an irregularly oval macula present medially in basal 1/2 (
Fig. 18
); venter yellow; abdomen yellow except apex of basal abdominal ventrite. Head punctures not visible, hidden in alutaceous sculpture; pronotal punctures small, separated by less than to 3 times a diameter; elytral punctures larger than on pronotum, separated by less than to 4 times a diameter, becoming larger, denser toward lateral margin; prosternum with small punctures separated by less than a diameter; mesosternum with coarse punctures separated by a diameter or less; metasternum with punctures smaller than on mesosternum, separated by 1 to 3 times a diameter in median 3/4, punctures becoming absent in lateral 1/4; abdominal ventrites 1, 2 with coarse punctures separated by less than to twice a diameter; ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided, 1.2 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved (
Fig. 19
); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side short, straight, extended from apex of intercoxal process 1/4 distance to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite slightly flattened along posterior ventrite margin, extended 7/8 distance to rear margin of ventrite. Genitalia with basal lobe as long as paramere, sides gradually narrowed from base to abruptly rounded apex; paramere slender, nearly straight, apex rounded (
Fig. 20, 21
); penis with apical portion divided; basal capsule slender, inner arm long slightly curved, apex truncate, outer arm long, straight, apex abruptly curved (
Fig. 22
).
Female.
Similar to male except spermathecal capsule slender, ramus not enlarged, cornu evenly curved to rounded apex (
Fig. 23
).
Variation.
Length 2.0 to
2.4 mm
, width
1.8 to 2.3 mm
. Pronotal color varies from entirely yellow to lateral 1/3 yellow with all intergrades between, size and shape of elytral maculae vary slightly.

Remarks.
This species is possibly conspecific with
P
.
traci
in spite of the quite different dorsal color patterns. The male genitalia are virtually identical and both are from
Brazil
. They are maintained as separate species because of the different color patterns.
