Type species. Eurygona? pulcherrima Herrich-Schäffer, [1853] .

Definition. As shown above, Eurygona? pulcherrima Herrich-Schäffer, [1853] ( type locality in Suriname) belongs to the genus Isapis E. Doubleday, 1847 ( type species Papilio agyrtus Cramer, 1777 ) and not to Themone Westwood, 1851 ( type species Helicopis pais Hübner, [1820] ) ( Fig. 21). However, it is genetically differentiated from the type species of Isapis at the subgenus level, e.g., their COI barcodes differ by 6.5% (43 bp). Therefore, we propose that the lineage with Isapis pulcherrima represents a new subgenus. This subgenus differs from its relatives by a combination of the following characters: each wing is blackish-brown with a yellow stripe by its base beneath (as in the type species of Isapis ) and on the hindwing. In DNA, a combination of the following characters is diagnostic in the nuclear genome: cne3301.6.2:T166A, cne3301.6.2:C186T, cne178.3.20:T1233A, cne178.3.20:T1632A, cne37196.1.3:A87T and in COI barcode: T67A, T82C, A211G, 223A, A268T, T625G.

Etymology. The name of the type species, pulcherrima , is a Latin word meaning very beautiful, most beautiful, or prettiest. The name of the new subgenus is formed from the Greek word Καλλίτερη (kallíteri), which means most beautiful. The name is a feminine noun in the nominative singular.
