Differential Diagnosis. Members of P. pampinus   are differentiated from other members of the andreaei   group by the denser elytral serial punctures ( Fig. 16 View FIGURE 16 ). The aedeagus of P. pampinus   has a long flagellum, as do those of P. retinaculus   and P. lemniscus   , but otherwise the aedeagi of the three are quite dissimilar ( Figs. 19, 20, 22 View FIGURES 19–22 ). Females of P. pampinus   have the explanate elytral margin very wide, continuing posteriorly to the sharply rounded posterior angles, and the apices are markedly truncate, conjointly forming a line perpendicular to the longitudinal axis of the elytra.

Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.80/0.75; head 0.31/ 0.46; pronotum 0.38/0.56; elytra 1.18 /0.75. Dorsum piceous to black, maxillary palpi, legs and venter dark brown. Submentum and mentum microreticulate, dull, sparsely punctulate.

Head with labrum very finely, very sparsely punctulate, shining. Clypeus and frons microreticulate laterally, disc shining, finely sparsely punctulate, punctures separated by about 2–6xpd, size of punctures less than 1xef. Anteocellar sulci deep. 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 2/3, with narrow hyaline border; discal reliefs strongly shining, finely, sparsely punctate, interstices ca. 2–6xpd; punctures about 1xpd of frons punctures; posteriorly punctures much larger, about 2xef; with foveae as follow: median anterior elongate and smaller posterior, shallowly confluent; a small anterior and larger oval posterior admedian, both rather deep; and a large anterior and small deep posterior adlateral on each side; discal foveae punctate and microreticulate; punctures on discal reliefs without discernible setae.

Elytra non­carinate, parallel­sided or nearly so, apices truncate; sutural apices rectangular; sides smooth, weakly explanate; posterior declivity gradual. Serial punctures moderately large and deep, on disc slightly larger than largest pronotal punctures, interstices on disc about 1xpd, or less; punctures of some series becoming progressively smaller over posterior declivity; without granules. Series one striate­impressed, more strongly in posterior 1/2 than anterior 1/2. Intervals flat or very weakly rounded, width on disc about 1–2xpd. Most punctures with very short, very fine seta.

Metaventral disc rather flat, with shallow 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 inverted V­shaped basomedian area on metaventrite in front of intercoxal sternite. Ventrite 6 dull, with sparse setigerous punctures across distal 1/2.

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 main­piece length ca. 0.50 mm, flagellum very long, coiled; main­piece rather stout, distal angulation large, acutely pointed ( Fig. 22 View FIGURES 19–22 ).

Etymology. Named in reference to the curled aedeagal flagellum.

Distribution. Currently known from four widely separated localities in western and southern South Africa ( Fig. 96 View FIGURES 95–96 ).
