Eprius planus (Weeks, 1901) and Eprius penna ( Evans, 1955) , new combinations

Pamphila planus Weeks, 1901 (type locality in Bolivia) ( Fig. 6 orange), currently in Mnasicles Godman, 1901 (type species Mnasicles geta Godman, 1901 ), is not monophyletic with it and instead originates near Eprius Godman, 1901 (type species Epeus veleda Godman, 1901 ) ( Fig. 6 green). COI barcodes of E. veleda and P. planus are 8.5% (56 bp) different, which is within the range known for congeners. Additionally, Styrioides [sic] penna Evans, 1955 is morphologically similar to P. planus . All these species possess a narrow brand segment along forewing cubitus in cell CuA 1 -CuA 2, short undivided and rounded uncus, bottle-shaped taken together with tegumen in dorsal view, and an unusual aedeagus end elaborate with spikes. For these reasons, we propose Eprius planus (Weeks, 1901) , comb. nov. and Eprius penna ( Evans, 1955) , comb. nov. However, the structure of the 3 rd segment of palpi is quite different between E. veleda (thin and rather long) and E. planus with E. penna (stout and conical). Analysis of other relatives will shed more light on these similarities and differences.

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.
