Type species. Lemonias lencates Hewitson, 1875 .

Definition. Genomic phylogeny reveals that a clade of Pachythone H. Bates, 1868 (type species Pachythone erebia Bates, 1868) species formerly placed in Roeberella Strand, 1932 (type species Lemonias calvus Staudinger, 1887) (Fig. 23 labeled aquamarine) is genetically differentiated from the rest at least at the subgenus level, e.g., COI barcodes of Pachythone erebia and Pachythone lencates (Hewitson, 1875) differ by 10% (66 bp). Therefore, this clade represents a new subgenus. This new subgenus differs from its relatives by the following combination of characters: forewings with a straight to slightly concave in the middle costal margin and a nearly hooked apex; wings are brown with darkerbrown spots and dashes, beneath paler and with whiter areas and stronger brown spotting with at least some dark spots framed with white; and a dorsal hindwing with white stripes and spots and at least with a predominantly white anal fold. In DNA, a combination of the following characters is diagnostic in the nuclear genome: cne9146.3.1:A1335C, cne9146.3.1:C1366T, cne81.7.1:G66A, cne81.7.1:T70A, cne10454.2. 3:A303T; and in COI barcode: A88T, T220C, T281C, T349A, T475C.

Etymology. The name is formed from the type species and is a feminine noun in the nominative singular.
