Punargentus tandilensis (Kohler, 1939) (Cosmosatyrus) n. comb.

(Figs. 10 D; 29)

Lectotype: (male) coll Breyer, 7 Dec. 1930 (MACN?) (photo examined).

Type location: Tandil, Buenos Aires Province, Argentina.

Other combinations:

Argyrophorus tandilensis —D’Abrera (1988, p. 798); Pyrcz & Wojtusiak (2012)

Cosmosatyrus tandilensis — Heimlich (1972)

Etcheverrius tandilensis — Lamas & Viloria (2004, p. 216)

Distribution. The species is endemic to a relatively small area of Buenos Aires Province, Argentina, not particularly close to the distribution of most other south-temperate pronophilines (Fig. 29). Diagnosis. Wing shape and general facies quite similar to P. chiliensis, and both were placed in the nowsynonymized genus Etcheverrius by Lamas & Viloria (2004). P. tandilensis differs from P. chiliensis in being generally gray-brown on the ventral surface (Fig. 10 D). There are dark, sinuate AM and PM bands on the HWV that separate a mottled brownish basal area from a lighter postmedial region. The whole hindwing is overlain by a ripple pattern. The forewing M1-M2 ocellus is oval and not pupillated.

Remarks. This species was not available for detailed study.
