DIAGNOSIS: The specimen illustrated in Bassi & Mey (plate 36, fig. 15) is not a P. amathusia but the holotype of P. eberti sp. n. described below. Males of P. amathusia (Fig. 7) differ from those of P. eberti (Fig. 8) in having more strongly developed rami of the antennae. In addition, the forewings have a poorly defined coloration, the hook is very evident, there is no well-defined subterminal area, and there are only three black subterminal dots, all below the hook. In male genitalia P. amathusia ( Bassi & Mey, 2011: fig. 284) has the uncus with double lateral processes, elongate valvae with a basal costal process with many small teeth, a longer phallus, and the tegumen simple. Female genitalia ( Bassi & Mey, 2011: fig. 285) have a more strongly sclerotized ductus bursae and the proximal sclerotized patch elongated and somewhat spiny as opposed to a membranous ductus bursae and rounded patch in P. eberti (Figs 39, 40).

ADDITIONS TO ORIGINAL DESCRIPTION (Fig. 7): Antennae in males with long rami. Wingspan in females up to 30 mm. Forewings with rounded apex and pale light

brown to greyish brown ground color; costal margin basally brown, then greyish white; pale yellow areas in proximal half and in cell; two brown bands at apex; three welldeveloped drop-like dots, all below hook; terminal line yellow, thick; fringes with short scales brown and long scales bronze, whitish and brown at hook. Hindwings yellowish brown; fringes yellowish white. Abdomen sandy brown. Sclerotizations of male abdominal segment VIII as shown in figure 36.

REMARKS: The above represents the correct type series. The best genitalia slide in BMNH is n° 5743, a male paratype from Bellerode near Windhoek. Unfortunately, the holotype’s genitalia are mounted on a slightly damaged slide .
