Description

Cabirus junta Evans, 1952 and Cabirus purda Evans, 1952, new status

Treated as subspecies since their description, Cabirus procas junta Evans, 1952 (type locality in Peru, Junín, Chanchamayo) and Cabirus procas purda Evans, 1952 (type locality in Peru, Loreto, Pebas), both described based on female holotypes, form distinct prominent clusters in the genomic tree (Fig. 2). The three distinct clades of Cabirus Hübner, [1819] exhibit genetic diversification suggesting three species-level taxa: Fst/Gmin for pairs of these taxa are 0.48–0.64/ 0.006 –0.012, suggesting nearly complete genetic isolation as evidenced by almost undetectable gene exchange between them. COI barcodes of C. p. junta (OM88.069) and C. p. purda (OM81.092) differ by 2% (13 bp) and they differ from the barcode of Cabirus procas procas (Cramer, 1777) (OM39.553) by 1.5% (10 bp) and 1.4% (9 bp), respectively. Males of these taxa are very similar and difficult to be distinguished, although those of C. p. procas have a reduced forewing subapical yellow patch, with crenulated distal margin, and a very reduced extension of yellow below forewing discal cell (Fig. 2a), whereas the yellow patches are wider, with smooth margins in both C. p. junta (Fig. 2b) and C. p. purda (Fig. 2c). On the other hand, females of these taxa are different in their facies and are distinguished by the amount of dark overscaling along hindwing veins from missing (C. p. purda, Fig. 2d left) to heavily expressed (C. p. procas). For all these reasons, we propose species-level for these taxa: Cabirus junta Evans, 1952, stat. nov. and Cabirus purda Evans, 1952, stat. nov.
