Definition and diagnosis. Phylogenetic trees reveal that two specimens identified as Cantha zara (E. Bell, 1941) (type locality in Bolivia, holotype sequenced as NVG-18022E02) show prominent genetic differentiation from it ( Fig. 6): e.g., their COI barcodes differ by 6.5% (43 bp), and therefore represent a new species. This new species keys to “ Cantha celeus zara ” (I.9.1(b)) in Evans (1955) but differs from it by rounder wings, browner (not reddish) ground color, and yellow framing at outer margins of both wings beneath, in addition to yellow veins. This species is not cryptic and is diagnosed reliably by phenotype. In DNA, a combination of the following base pairs is diagnostic in the nuclear genome: aly 2178.10.1:C102T, aly363.37.1:A909G, aly363.37.1:T3771G, aly1139.50.8:T279G, aly1139.50.8:T372G, and COI barcode: 67G, T74C, A88T, T508C, A535G, A565G.

Type locality. Peru: Madre de Dios Region, 30 km SW of Puerto Maldonado, elevation 300 m.

Etymology. The name is a compound word of Greek ζωηρός (zoirós) meaning lively, vivid, or vibrant, and διΚτυωτός (diktyotós) meaning reticulated. The name reflects the bright reticulated pattern of this species and is a noun in apposition.

Distribution. Amazonian Peru and Brazil.
