description: Revised key to species of P. (P.) elegans species-group
(the couplets 3–11 (except for P. (P.) litigiosum and P. (P.) elegans) represent P. (P.) alluaudi species-complex)
1 Setal vesture of entire dorsal body surface conspicuously black. Body with blue or violaceous blue tinge (faded in old specimens). Pronotal discal surface with continuous, conspicuously wide, rather blunt transverse ridges in middle. Posterior lobe punctate-setose. Labrum 6–10-setose..................................................................... 2
- Setal vesture of dorsal body surface whitish, blonde, straw-yellow or ferrugineous, rarely whitish setae partly mixed with greyish or blackened setae. Body pitchy black or blue, green-blue or violaceous-blue. Posterior lobe either smooth and glabrous, or foveolate-uneven, or punctate-setose. Labrum 4–8-setose...................................................... 3
2 Elytral punctation rather fine and almost regular. Aedeagus extraordinarily short (length 2 mm)................................................................................................ P. (P.) majunganum Jeannel, 1946
- Elytral punctures large and deep. Aedeagus extremely long (length 4 mm), nearly straight with enlarged apical portion and attenuated into thin, obtuse apex which is in dorsal view knob-like...................... P. (P.) sudiferum Rivalier, 1965
3 Setal vesture of body surface markedly ferrugineous. Body black. Pronotal disc in dorsal view subquadrate, cristulate-tubercu- late, in lateral view subgibbose. Posterior pronotal lobe smooth and glabrous. Elytral surface matt, very densely, partly notably irregularly punctate. Labrum 5–7-setose. Mandibles with reddish teeth................ P. (P.) meridionale Fleutiaux, 1899
- Setal vesture of body surface whitish, blonde to straw-yellow, never so distinctly ferrugineous; rarely mixed with blackened setae, particularly on legs............................................................................... 4
4 Posterior pronotal lobe punctate-setose, or glabrous but with uneven (wrinkled or foveolate) surface................... 9
- Pronotal posterior lobe glabrous, in one species sometimes with occasional setigerous punctures...................... 5
5 Pronotal posterior lobe mostly glabrous rarely with occasional setigerous punctures. Elytral punctation of very large punctures with narrow intervals. Elytral apex in female subtruncate in middle and with deep sutural emargination. Body metallic black or with faint, rarely intense, blue or greenish lustre. Temples extremely short, 3.2–4.2 times shorter than eyes... Aedeagus boomerang-like bent in middle and with more or less distinctly prolonged but wide and only slightly dorsad-bent apex................................................................................... P. (P.) praetervisum Moravec, 2005
- Pronotal posterior lobe always glabrous, smooth or almost smooth.............................................. 6
6 Body metallic blue or with only feeble, blue lustre, or with greenish-blue or bronze and blue iridescence. Elytral punctation of medium-sized punctures with rather wide and flat intervals. Elytral discal impression moderate. Temples short, 2.5–2.8 times shorter than eyes. Aedeagus with dorsally markedly hooked, but thick and blunt apex............................................................................................. P. (P.) elegans Brullé in Audouin & Brullé, 1834
- Body pitchy black or with blue lustre...................................................................... 7
7 Body entirely pitchy black. Pronotal disc with convex lateral margins, subglobose in female, its median surface densely tuberculate, umbilicate-tuberculate to tuberculate-cristate. Setal vesture whitish to straw-yellow. Elytral apex with right-angled, rarely acute-angled inner tooth in both sexes. Aedeagus conically tapered towards rather narrow and small, dorsad-bent, rounded apex, which is in its ventral (and dorsal) aspect conically attenuated and nearly pointed................................................................................... P. (P.) natsuae Moravec, Razanajaonarivalona & Hori, 2020
- Pronotal disc with subparallel or parallel lateral margins, or notably elongate and ellipsoidal.......................... 8
8 Body entirely pitchy black. Pronotal disc dorsally quadrate with almost parallel lateral margins in male, much wider but still with slightly subparallel lateral margins in female, in lateral view subgibbose. Discal surface with irregular, transverse short rugae on medial area. Mandibles with reddish teeth. Aedeagus notably boomerang-like bent in middle with only indistinctly ventrally bent, narrow, blunt apex................................................. P. (P.) rivalieri Moravec, 2005
- Body black with diffusing bluish lustre. Pronotal disc dorsally mostly notably elongate, ellipsoidal, in lateral view never subgibbose. Elytral punctation rather fine. Temples 2.5–3 times shorter than eyes. Aedeagus voluminous, dorsally shortly constricted into small, beak-like apex (bird-like shaped)................................ P. (P.) litigiosum Rivalier, 1970
9(4) Pronotal posterior lobe glabrous but with uneven, wrinkled or lacunose surface................................... 12
- Pronotal posterior lobe punctate-setose................................................................... 10
10 Body rather slim, black-blue to violaceous-blue. Pronotal disc rather densely irregularly transversely striate-rugulose. Temples very short, 2.8–3.2 times shorter than eyes. Elytral apex of female with rounded inner area lacking sutural emargination. Aedeagus rather short, only moderately bent in middle, its apex narrow, slightly bent dorsally. Pronotal posterior lobe covered with large setigerous punctures....................................................... P. (P.) alluaudi W. Horn, 1898
- Body either entirely pitchy black or with blue or violaceous-blue lustre. Pronotal disc in its lateral aspect subgibbose. Setal vesture whitish to straw-yellow, sometimes mixed with blackened setae......................................... 11
11 Body mostly black, rarely with blue or violaceous-blue lustre (faded in old specimens). Pronotal disc with arcuate-convex lateral margins (broadly ellipsoidal). Elytral punctation notably coarser. Temples very short, 2.9–3.4 times shorter than eyes. Aedeagus long with narrowly cylindric-elongate, moderately bent and rounded apex.. P. (P.) atrorotundatum W. Horn, 1934
- Body pitchy black. Pronotal disc dorsally with distinctly arcuate-convex lateral margins, subglobose in female. Discal surface tuberculate, to tuberculate-cristate on median area, tubercles often umbilicate. Elytral punctation comparatively fine. Labrum 7–8-setose. Aedeagus conically tapered towards rather small, rounded, only very slightly dorsad-bent apex; in its ventral (and dorsal) aspect conically attenuated and narrowed into moderately elongated, cylindric, rounded apex................................................................................................. P. (P.) ondravybirali sp. nov.
12 Body black with only faint bluish lustre, length not exceeding 10.5 mm. Elytral discal impression very faint............ 13
