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 .
