Type Material. HOLOTYPE: Male. //“ 13Km S. of Lawn Hill Stn. via Mt. Isa N. Qld. 7.ix.1983 R. I. Storey ”// “ U.C. Berkeley EMEC705,230”//, [Deposited QM, Reg. No. T245525].
Type Locality and Distribution Range. Based on the holotype label, the type locality is established as Boodjamulla (Lawn Hill) National Park (Fig. 19), near 18°42’S 138°31’E at approximately 130 m elevation.
Diagnosis. Members of this species are relatively large beetles that are similar to P. macleayi and P. robustus but lack the enlarged first antennomere of the former and are impunctate in the basal impressions of the pronotum, unlike P. robustus, which is distinctly punctate. All three have distinctly different male genitalia.
Description. Size: sbl = 8.0 mm; greatest width across elytra = 2.9 mm. Color: Dorsal and ventral surfaces castaneous; legs, mouthparts, and antennae very slightly paler brunneous. Dorsally distinctly and ventrally slightly shiny. Dorsally with spectral iridescence, venter, elytral epipleura, and legs without spectral iridescent. Head: Dorsal microsculpture not evident at 50X magnification. Clypeal-ocular region with impressions only represented by extremely shallow depressions. Ocular ratio = 1.30. Eyes relatively small, somewhat flattened with moderately large posterior orbital area, single subocular carina low, not sharply defined and region slightly rugose. Labrum with anterior margin straight. Median tooth of mentum rounded across apex. Antennae long, antennomeres 8–11 surpassing pronotal base. Thorax: Pronotum dorsally with a few punctures only in center of basal impressions, microsculpture not evident at 50X magnification. Pronotum widest well anteriad of middle, lateral margins moderately arcuate, converging to base, not sinuate. Lateral marginal bead narrow, widening very slightly near base and extending slightly and obscurely along base but lacking a distinct bead; basal margin without marginal bead; anterior angles prominent, rounded-triangular; hind angles obtuse, slightly rounded; basal impressions linear, sharp, wellimpressed, reaching basal margin. Seta at hind angle in marginal bead. Elytra parallel-sided, dorsally depressed, epipleura in dorsal view very slightly sinuate at level of umbilicate marginal puncture 7. Elytral striae finely, shallowly crenulate-punctate. Elytral microsculpture hardly evident at 50X magnification, where apparent very transverse. Intervals very slightly convex, more convex in apical third. Eltral plica large, prominent. Prosternal process rounded, deeply margined. Prosterna smooth except for cluster of fine punctures medially. Meso- and metasterna coarsely punctate. Abdomen: Abdominal ventrites densely punctate, shallowly rugose. Aedeagus: Medium lobe short in lateral view, tip emarginate in ventral view, no spines or spinules visible on endophallus in repose.
Etymology. A Latinized noun in the nominative case honoring the late Ross I. Storey, formerly of the Department of Primary Industries (QDAF), Mareeba, QLD, an extraordinary Coleopterist and collector of the type specimen of this species.
