 Diagnosis. Among the species with pronotal median process distinctly protruding over the head, P. saccharatu s differs by pronotal lateral notch circular and almost closed.   
 In many of the examined collections, specimens identified as P. saccharatus belong to P. c h lo re us sp. n.   
 Re-description. Body length: 7.0 mm.   
Body convex, about 1.5–2 times as long as wide (ratio max length/max width: 1.75–1.77); colour brown, darker on central and apical portion of elytra, lighter on pronotum; body vestiture consisting of short, dense, recumbent whitish setae, holding a coat of dirt which forms a uniform encrustation.  
Head transverse; eyes protruding lacking interfacetal setae; long, fine setae just posterior to eyes; supraorbital carina raised, indented with a distinct upwardly directed, pointed tubercle at posterior end, above the eye; supraantennal carina distinctly raised, frontal edge indented; antennal insertion frontal, just below the edge of supraantennal carina; antennae 11-segmented with a distinct 3-segmented club; antennomere I slightly elongate, about as long as III; II subspherical; III distinctly longer than II; IV–VIII from subcylindrical to subspherical gradually decreasing in length; IX–XI transverse to form a rather loose club.  
Pronotum distinctly transverse (pronotal length/width: 0.64), as wide as elytra; dorsal median process, anteriorly prominent and long, reaching anterior margin of head, slightly sloping in lateral view with pointed tubercles on dorsal edge; antero-lateral margins widely lobate (7–8 lobes), expanded posteriorly to form a lateral notch, widely circular; two admedian upwardly pointed tubercles in middle.  
Elytra about 1.1 times as long as wide (elytral length/width: 1.10–1.13), with straight lateral margins and distinctly indented margins; strongly prominent tubercles along 3rd and 5th intervals; 3rd interval with tubercles variable in size and shape, joined to form a crest, weakly zigzag; proximal third of crest convergent, reduced to digitiform tubercles; apical tubercle distinctly raised, with edge smoothly indented, pointing backwards; 5th interval with basal tubercle larger than others on same interval, with pointed edge.  
 Distribution and habitat occurrence. NE and SE Queensland and NE New South Wales (Fig. 14 c); most of the records are from upland subtropical rainforest with a few from lowland subtropical rainforest in SE Qld and upland tropical rainforest in the Wet Tropics and a single record from upland temperate rainforest (Carrai Plateau in NSW).
