Rhomba mirnae (Siewert, Nakamura & O. Mielke, 2014) , new combination

Genomic sequencing of the holotype of Psoralis mirnae Siewert, Nakamura & O. Mielke, 2014 (type locality in Guatemala) ( Fig. 6 purple), currently in Alychna Grishin, 2019 (type species Pamphila exclamationis Mabille, 1898 ), reveals that it is not monophyletic with either Psoralis Mabille, 1904 (type species Psoralis sabaeus Mabille, 1904 , which is a junior subjective synonym of Pamphila idee Weeks, 1901 ) or Alychna , but instead groups closely with Rhomba gertschi (Bell, 1937) , which is the type species of Rhomba Grishin, 2022 ( Fig. 6 cyan). The COI barcode difference between A. mirnae and R. gertschi holotypes is 4.7% (31 bp) which is well within the range of close congeners. Their genitalia are largely similar in having widely separated short and stout uncus arms, nearly rectangular tegumen in dorsal view, broad valva and upturned harpe with nearly straight and serrated or slightly concave dorsal margin armed with a proximal and a distal tooth. Therefore, we propose Rhomba mirnae (Siewert, Nakamura & O. Mielke, 2014) , comb. nov.

FIGURE 6. Nuclear genome tree of selected Moncina: Psoralis and Artines relatives. See Fig. 4 for notations. Note extreme heterogeneity of evolutionary rates in different lineages, compared to mostly homogenous rates in Fig. 4 tree. Some genera are labeled at their clades. Taxa discussed in the text are shown in different colors: Mucia (blue, with Mucia rusta, comb. nov. labeled in dark blue), Rhomba (cyan, with Rhomba mirnae, comb. nov. labeled in purple), Eprius (green, with Eprius planus, comb. nov. and Eprius obrepta, stat. nov. labeled in orange and olive, respectively), Panca (violet, with Panca fiedleri, comb. nov. labeled in brown), Eutocus (red, with Eutocus brasilia, comb. nov. and Eutocus fosca, comb. nov. labeled in magenta), and Lattus (gray, with Lattus minor, comb. nov. labeled in dark green). Green arrows point from the clade of the genus where a species was placed previously (name in square brackets) to the clade of the species that is being transferred between genera.
