Distribution. Philippines: Palawan Island.

Description. Body elongate and slender, dark, glossy. Elytra dark, with two transverse white bands. Body length: 6.5- 7.9 mm, largest width: 0.9mm.

Head slightly transverse, with large and convex eyes. Portion of head between antennal bases with wide impression. Frontal part of head behind clypeus flattened, with coarse punctuation and fine short pubescence. Posterior portion of head glossy, with sparse and coarse punctuation. Cheeks under eyes small, with some long setae and sparse pubescence in lateral portion. Mandibles dark-brown, sharp, with coarse punctures and pubescence laterally. Labrum yellow-brown, glossy, with concaved apical margin, with pubescence and small punctures. Clypeus yellow-brown, very short, glossy, transverse. Antennae long and slender, on male and female longer than length body. Antennomeres shiny, with short pubescence and a brush of long setae. Basal antennomeres 1-4 thickened apically, slightly concave, dark, antennomeres 5-9 yellow or yellow-brown.

Pronotum elongate, subcylindrical, with dorsal and lateral tubercles. Length: 2.0- 2.3 mm, maximal width: 0.8 - 1.3 mm. Anterior and posterior border portions prominent, shiny; pronotum distinctly longer as wide. Pronotal disc with a pair of lateral protruded tu-bercles and five dorsal tubercles on the disc: three tubercles located in anterior portion, and two tubercles located in posterior portion. Pronotum shiny, with very fine microsculpture, wrinkles and very fine, sparse punctuation in middle, with lateral pubescence. Ventral surface of prothorax with white pubescence, and some additional longer setae. Scutellum wide, rounded apically, with dense white pubescence. Pars stridens distinct, rounded apically, smooth, with very fine transverse microsculpture, iridescent.

Elytra translucent, flattened, narrowed near middle and slightly broadened posteriorly; apical margin of elytra not reaching apex of abdomen. Elytra dark-brown, with two relatively wide transverse white translucent bands. Anteromedian portions of each elytron ovally impressed at base near suture, with sparse and fine punctuation;

each puncture bearing a pale seta. Surface of elytra with fine rows of relatively sparse and fine punctures.

Ventral surface of body smooth, with sparse punctation and setation. Legs relatively long and thin, with apically thickened femora. Widest part of femora black, other portions yellow. Tibia dark-brown, flattened at external border, with fringe of dark and long setae. Tarsomeres yellow, covered by sparse, golden pubescence.

Differential diagnosis. In the generals hape of the body, the new species is similar to P. bifasciatus Vives, 2015 , known from Luzon, but differs from it by the following char-acters: 1) different shape of transverse bands on the elytra: new species with two distinctly marked transverse bands, which is almost the same width, but elytra of P. bifasciatus with two indistinctly marked striated bands, which are usually not of equal width; 2) Antennomeres of new species unicolored, but P. bifasciatus bicolored.

Etymology. This species isnamed after its place of origin - Palawan Island [Palawan - palawanensis ].
