Pseudonymphidia Callaghan, 1985 is a subgenus of Pachythone H. Bates, 1868

Currently treated as a genus, Pseudonymphidia Callaghan, 1985 ( type species Emesis clearista Butler, 1871 ) includes species that are phenotypically similar to species in the subgenus Lenca subgen. n. ( type species Lemonias lencates Hewitson, 1875 ) of Pachythone H. Bates, 1868 ( type species Pachythone erebia Bates, 1868 ), and all these species are differentiated genetically from each other at the subgenus level ( Fig. 23 blue), e.g., COI barcodes of the type species of Pseudonymphidia and Pachythone differ by 9% (59 bp). Therefore, we propose that Pseudonymphidia Callaghan, 1985 stat. nov. is a subgenus of Pachythone H. Bates, 1868 .

Different genera are colored differently, and different subgenera are labeled in different colors: Parvospila (brown with subgenus Lucispila subgen. n. labeled in magenta), Zelotaea (green with subgenus Byzia subgen. n. labeled in pink), Aricoris (purple with subgenera Arichlosyne subgen. n. and Ariconias stat. nov. labeled in orange and gray, respectively), Lemonias (cyan with subgenus Thisbe stat. nov. labeled in bright purple), Uraneis stat. nov. (red), and Pachythone (blue with subgenera Pixus Callaghan, 1982, Lamphiotes Callaghan, 1982, Lenca subgen. n., and Pseudonymphidia stat. nov. labeled in maroon, dark blue, aquamarine, and olive, respectively). Ultrafast bootstrap (Minh et al. 2013) values are shown at nodes.
