Pamperis poaoeneis Heimlich, 1959

( Figs. 3 D; 22; 28)

Holotype: (male) ZSM No. 296 (photo examined, Fig. 38) Type location: Volcán Osorno, Chile at 1300m Other combinations:

Argyrophorus poaoeneis — Pyrcz & Wojtusiak (2010)

Distribution. Known from the type locality on Volcán Osorno in the Lake District of Chile, and also reported near Esquel, Chubut Prov., Argentina ( Pyrcz, 2012) ( Fig. 28 ).

Diagnosis. Without a red patch on the dorsal forewing and lacking an M1-M2 ocellus on the ventral forewing with four small, white ocelli between M1 and CuA2 on the ventral hindwing. Forewing discal cell lacks M1-M2 and M2 extends several millimeters into the discal cell. Rs1 fuses with Sc three quarters of the way from Sc.

Redescription. Forewing ( Fig. 3 D): Wingspan approximately 30mm. Termen entire with the discal cell lacking the M1-M2 vein. M2 extends several millimeters into the discal cell and Rs1 fuses with Sc three quarters of the way from the base of the wing to the costa rather than continuing to the costa more or less parallel to Sc. Fringe scales are cream and dark brown, giving the appearance of fine crenulation. Dorsal wing is evenly dark brown while the ventral wing is dark coffee brown at the proximal half with a lighter postmedian band, deckle edged at the proximal border and nearly straight at the distal border. Subterminal band is darker brown. Ocellus between M1- M2 is completely absent.

Hindwing ( Fig. 3 D): Hindwing oval with the termen barely scalloped and the dorsal side similar in color to the dorsal forewing. Discal cell is more or less spatulate, Rs-M1 bulging outward and M1-M2 curving inward only very slightly. Ventral hindwing with a ripple pattern in dark coffee striations over the entire wing. Proximal twothirds of the wing is darker brown and the postmedian band is lighter brown, extending to the termen, and with the proximal border deckle-edged.

Material examined. Holotype photo.
