Derivation of name. From tuber (Latin= a swelling) for the elytral tubercles.

Diagnosis. This species is most similar to P. g e m m a n s (Baly) and can be distinguished by antennomere I being subglobose, by antennomere III being the longest, and by having four tubercles on each elytron.

Description. Metallic green and yellow, with antennae and legs paler. Head: vertex alutaceous; slight medial sulcus present; tooth present between antennal bases; frons with small tubercle in middle. Antenna: antennomere I globose; II­VII cylindrical, II thicker than others, III longest; VII­X transverse; XI pointed at apex; I­VII glabrous; VIII­XI setose. Pronotum: lateral margin sinuate for basal, angulate in middle, sinuate and converging to apex; each anterior angle with small tooth; disc strongly convex, densely, coarsely punctate; longitudinal medial sulcus present; pronotal length 0.7 mm; pronotal width 0.7 mm. Scutellum: quadrate; alutaceous. Elytron: lateral margin sinuate, smooth; apical margin rounded, smooth; humerus produced, flattened; interspace 7 strongly carinate; with 10 rows of punctures plus short scutellar row and four elongate tubercles­ first between puncture rows 2 & 3 on basal, second between puncture rows 2 & 3 near middle, third between puncture rows 4 & 5 just behind middle, fourth between puncture rows 2 & 3 on apical 1/4; elytral length 2.4 mm; elytral width 1.4 mm. Venter: pro­ and mesosterna punctate medially, rugose laterally; metasternum granulose. Leg: tibia expanded at apex. Total length: 3.6 mm.

Variation. Specimens vary in pronotal length from 0.7­0.8 mm, in pronotal width from 0.7­0.8 mm, in elytral length from 2.2­2.6 mm, in elytral width from 1.3­1.5 mm, and in total length from 3.4­3.8 mm. The color and sculpture is very similar to that of the holotype.
