Punargentus angusta angusta ( Weymer, 1911) (Argyrophorus)

( Figs. 11 B; 29)

Holotype, formerly in Berlin; destroyed in World War II. Type locality: “ Bolivia ”

Subspecies:

Punargentus angusta picota ( Fuchs, 1954) (Argyrophorus) Lectotype (male) and paralectotypes: Zoologischen Museums der Universität Hamburg. Type locality: cordillera near Ayacucho, Peru 4000–5000m., July 1920. Other combinations:

Punargentus lamna angusta — Heimlich (1972)

Distribution. High altitude altiplano of Peru and Bolivia ( Fig. 29).

Remarks. Weymer described the nominate taxon as a “local form” of Argyrophorus lamna , and it was still considered a subspecies of P. l am na by Heimlich (1972), who viewed Argyrophorus picota Fuchs as a junior synonym. D’Abrera (1988) indicated P. lamna and P. angusta as separate species, and Lamas and Viloria (2004) maintained Punargentus angusta at specific rank and listed P. angusta picota as its subspecies. As these taxa are extralimital to the south-temperate region and so not a focus of our research, we did not have material to examine, but photographs of specimens ( Fig. 29) suggest a very close relationship between P. l am na and P. angusta , if the two are not, indeed, the same. Both exhibit the lenticular black ocelli in the fore and hindwing cells, bordered by or superimposed upon elongated yellow streaks that are diagnostic of Punargentus .
