Differential Diagnosis. This species is similar in dorsal habitus to P. aeneus  , including the widely explanate elytral margins of the female. Among other characters, P. sebastiani  ( Fig. 7View FIGURE 7) differs from P. aeneus  by the slightly smaller size, the longer maxillary palpi, and the lack of dorsal metallic reflections. In addition, the male labrum is apicomedially notched in P. sebastiani  , arcuate and reflexed in P. aeneus  ; in females, the sixth ventrite has a median depression in P. aeneus  , whereas this depression is absent in P. sebastiani  . The aedeagus of P. sebastiani  ( Fig. 12View FIGURES 11–14) is quite different from that of P. aeneus  .

Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.67/0.67; head 0.32/ 0.45; pronotum 0.36/0.51; elytra 1.98 /0.67. Dorsum of head and pronotal disc piceous, remainder of pronotum and elytra dark brown, maxillary palpi and legs brown. Submentum and mentum microreticulate, sparsely punctulate.

Head with labrum very finely, very sparsely punctulate, shining. Clypeus entirely and frons on disc shining, sparsely, finely punctulate on disc, punctures separated by about 2–5xpd, size much smaller than eye facet. Frons microreticulate at sides, in deep anteocellar sulci. Ocelli distinct.

Pronotum cordate, widest in front of middle; anterior angles obtuse, posterior rectangular; sides finely margined, weakly crenulate; anterior margin shallowly arcuate over median 3/4, with narrow hyaline border; discal reliefs shining, very finely, very sparsely punctate, interstices ca. 4–8xpd; anteriorly and posteriorly punctures much larger, about 2xef; with foveae as follow: median anterior elongate and smaller posterior, very shallowly confluent; a small anterior and small, oval posterior admedian; and a large anterior and small deep posterior adlateral on each side; foveae punctate, not microreticulate; punctures on discal reliefs without discernible setae.

Elytra non­carinate, parallel­sided or nearly so in anterior 1/2 where explanate margin is slightly wider (see females, below), apices subtruncate; sutural apices rectangular; sides smooth, moderately explanate; posterior declivity moderately abrupt. Serial punctures moderately large and deep, about 1xpd of largest pronotal punctures, interstices on disc about 1xpd; without granules. Series one striate­impressed in posterior 1/2. Intervals flat or very weakly rounded, width on disc about 1–2xpd. Most punctures without a discernible seta.

Metaventral disc rather flat, with midlongitudinal impression in basal 1/2. Thoracic ventrites and abdominal ventrites 1–5 clothed with dense setae except glabrous midlongitudinal prosternal ridge, glabrous dull mesoventral plaques and small glabrous strongly shining inverted V­shaped basomedian area on metaventrite in front of intercoxal sternite. Ventrite 1 with weak submedial basal carina on each side; ventrite 6 shining, with sparse setigerous punctures across distal 1/2.

Legs of male with 2 very small setae on apical protarsomere. Femora and tibiae alutaceous.

Females with very wide explanate elytral margin, continuing to sharply rounded posterior angles, apices

markedly truncate, conjointly forming line perpendicular to longitudinal axis of elytra.

Wings fully developed on holotype and all dissected males.

Aedeagus length of main­piece ca. 0.31 mm; flagellum very long, coiled; main­piece stout, of rather uniform width throughout length, in both views ( Fig. 12View FIGURES 11–14).

Etymology. Named in honor of Sebastian Endrödy­Younga.

Distribution. Currently known from northeastern Lesotho and a few localities in that general area, in Eastern Cape Province and Free State Province ( Fig. 95View FIGURES 95–96).
