Luzon, Benguet, XII.2013 " < Fig. 11P >. 1 female (CRS), " Philippines —E Luzon, Sierra Madre, Tapsoy , Quirino VI.2014 " . 1 female (CRS), " Philippines, Eastern Visayas , Samar VIII.2013 " < Fig. 62D >.

Comparisons. This species has an extraordinary elytra pattern making it easily distinguishable in the genus. It could be close to P. politissima for the similarities in their external features and male genitalia. These two species are different from others in the P. nigrolineata group by: elytra striae barely incised, elytra disc distinctly depressed near basal third. P. andrewesi is also different from the other species of this species group in: apex of abdominal sternite VII well emarginate in males; gonocoxite II of ovipositor more elongate.

Description. Body length 9.0– 9.7 mm. Dorsum dark brown, antennae completely reddish brown, mouthparts, lateral margins of pronotum, venter, and legs reddish brown. Elytra with three groups of yellow patches: basal one elongate, length of one-sixth as elytra, as wide as fourth interval or wider; middle one faint, always covering second discal pore, sometimes extending lateral-posteriorly; apical one largest, forming continuous cordate patch occupied inner four or five intervals, always covering third discal pore. Frons distinctly punctate; postgenae without suborbital setae; antennae hardly reaching pronotal base; labrum quadrate, apex faintly pointed at middle; mentum with a pair of minute median setae. Pronotum rounded-hexagon, PW/PL = 1.29–1.36, nearly same width as head, PW/HW = 0.96–1.04; widest at anterior third, strongly narrowed to base, clearly sinuate before posterior angles; posterior angles widely obtuse. Elytra slightly dilated to apex, surface with shallow but clear isodiametric microsculpture; striae barely incised, with fine puncture rows; interval not convex, with very spares punctures; disc with deep and large depressions near basal third of intervals 3 to 6. Males with uniseriate adhesive setae on apical half of mesotarsomere 1, and biseriate setae on almost full length of mesotarsomeres 2–3. Apex of abdominal sternite VII well emarginate in males. Median lobe of aedeagus slightly stout (AL/AW = 4.6), ventral margin expanded in lateral view; right margin weakly sinuate before apical lamella; apical lamella wide rounded-triangular, LL slightly smaller than LW, apex weakly bent upward in lateral view. Endophallus with distinct flared basal expansion of primary sclerite; flagellum extending to the base of apical orifice; apical sclerite narrowly V-shaped, well chitinized, basal core distinct, ovate, heavily chitinized and scaled; squamate sheath small, heavily scaled, with basal and apical sheath similar in size; squamate sac well divided, near middle of median lobe, dorsal to squamate sheath; proximal and distal sacs dorsal-ventrally compressed, distal sac much smaller than proximal one. Gonocoxite II of ovipositor elongate, one and half length as basal width, apex curved with small denticle near inner apical angle, with two ensiform setae on inner apical angle, one near apical denticle, two or three on outer apical angle.

Distribution ( Map 10 , red). Only known from the Philippines: Luzon and Eastern Visayas.

Remarks. Jedlička (1963: 442, fig. 159) illustrated the elytra pattern of this species, but none of the three patches accords with the actual specimen ( Fig. 62C ).
