( Figs. 99–108 View FIGURES 99–104 View FIGURES 105–108 , 165 View FIGURE 165 )

Diagnosis: Male. Length (1.94–2.00 mm). Width (1.31–1.44 mm). Ovate; cuticle dark brown, matte, antenna orange, club darker. Vestiture of sparse recumbent ochreous to dark brown scales. Head with scales up to antennal insertions, basal half of rostrum rugose, apical half of rostrum finely punctate and shiny, scrobes lateroventral, reaching the margin of eyes, antenna inserted at middle of rostrum, funicle and desmomeres as in P. velizi , antennal club setose. Pronotum trapezoidal, annulate anteriorly, widened laterally at middle, punctures deep and wide, narrower than elytra, three dorsal vittae of ochreous scales, postocular lobes with vibrissae. Elytra with humeri produced, sparsely covered with scales, flanks almost bare and angulate, elytra dorsum surface basal half tuberiferous, two large subconical and laterally compressed tubercles on base of elytral declivity, both tubercles between striae 3 and 4, punctate-striate, punctures shallow, striae 10 complete. Abdominal ventrites with sparse deep punctures, punctures bearing setae, suture between abdominal ventrite 1 and 2 complete but not articulated, abdominal ventrites 3 and 4 together slightly shorter than abdominal ventrite 2, abdominal ventrite 5 apex finely punctate. Metanepisternal suture swollen. Front and middle femora armed with a small tooth, hind-femora unarmed, tibia uncinated. Pedon width gradually increasing from base to apex, temones 2.8x longer than pedon, genital sclerites sting-shape, opposite orientated.
