Paralycaeides Nabokov, 1945 is a subgenus of Itylos Draudt, 1921 and Eldoradina Balletto, 1993 of Nabokovia Hemming, 1960

Inspection of genomic trees reveals that two pairs of genera: (1) Itylos Draudt, 1921 (type species Cupido speciosa Staudinger, 1894 , which is a junior subjective synonym of Lycaena titicaca Weymer ,

1890) and Paralycaeides Nabokov, 1945 (type species Itylos inconspicua Draudt, 1921 ) and (2)

Nabokovia Hemming, 1960 (type species Thecla faga

Dognin, 1895 and Eldoradina Balletto, 1993 (type species Nabokovia (Eldoradina) cyanea Balletto ,

1993) are closely related to each other in each pair

(Fig. 23): COI barcode difference of 5.9%–6% (39–40 Fig. 23. Nuclear genome tree (autosomes): genus Itylos bp) in each pair. Furthermore, at least one genus in (red, subgenus Paralycaeides in magenta) and genus Nabokovia (blue, subgenus Eldoradina in violet color).

each pair consists of a small number of species.

Therefore, we propose to treat the junior name in each pair as a subgenus name: Paralycaeides Nabokov, 1945 of Itylos Draudt, 1921 and Eldoradina Balletto, 1993 of Nabokovia Hemming, 1960 .
