Catasticta amastris (Hewitson, 1874)

A medium­ to large­sized species, characterized by the strongly melanic pattern of the dorsal surface of the male, the female being much less melanic. General shape of both wings very rounded, with smooth apex of FW and rounded anal lobe of HW. FW discal band (both dorsally and ventrally) with a concave outer margin (all other related species with a straight or convex outer border). Both subspecies exhibit a stable wing pattern, though specimens of ssp. dentata show some degree of variability in the arrowhead­shaped spots of the HW above. The species is very poorly represented in collections, but is locally not scarce (Boyer, pers. comm.).

Distribution: Northern Bolivia (La Paz and Cochabamba, ssp. amastris ) to southern Peru (Puno and Cuzco, ssp. dentata ), between 2400 and 3450 m.

Lectotype specimens serve to tie the published name of a nominal taxon to an actual specimen, and as a reference standard for the application of that name. In order to preserve the stability of nomenclature by selecting one specimen as the unique bearer of the name, and following Art. 74.7 of the Code, we designate as lectotype of Catasticta dentata Lathy & Rosenberg, 1912 the male syntype in the BMNH from Peru, [Puno], Acopampa, 11,500', II–III.1910 (H. & C. Watkins) [examined], which was illustrated by D'Abrera (1981: 132).
