Taxonomy. Butler (1867, p. 467) described this species from Brazil, based on an unspecified number of specimens from Tapaj́os, in Bates ’s collection, and ‘Villa Nova’, in the NHMUK. The original description closely matches two female syntypesin the NHMUK from Tapajos ́and Villa Nova, in particular in describing the five main ocelli in the VHW as comprising three that are encircled with yellow and each having two pupils, and the remaining two as being yellow with a central silver line. Weymer (1911, p. 212, pl. 48f) described Euptychia libyef. gracilisbased on an unspecified number of specimens from Pebas, Peru, in the collection of Bang-Haas, and the figure of the ventral surface corresponds with the specimen labelled as lectotypeby Lamas in the SMTD. In comparison with the two syntypesof ocnus, this specimen is somewhat paler, and it has a distinct rather than vestigial ocellus in 2A-Cu2 on the VHW, but the remaining VHW ocelli and other wing pattern characters are otherwise typical of this species as here defined.
Distribution and natural history( Figure 32). Occulta ocnus gen.n.and comb.n.is known to date from the central Amazon basin, with all recorded localities being in the vicinity of large rivers below 250 m.A list of specimens examined is provided in Table S3. The only two records from Ecuador are from the region of black-water rivers and lakes north of the Río Napo; at Zancudococha, a male was collected flying near to the ground at the edge of forest and small field, on a low ridge, at 13:00 hrs. Immature stages have not been described. A list of specimens examined is provided in Appendix B.
Discussion. Occulta gen.n.is described as a monotypic genus for Euptychia ocnusbased on molecular data presented here. As previously indicated by Espeland et al. (2019a), Euptychia ocnusis distantly related to the typespecies of Magneuptychia, Papilio libyeLinnaeus, 1767. Although Papilio libyeis a member of the clade to which Occulta gen.n.is weakly supported as belonging, expanding the concept of Magneuptychiato include Euptychia ocnuswould be unreasonable, for a number of reasons. First, the support for its relationship with the clade containing Papilio libyeis low. Second, and perhaps more importantly, such a broad generic classification would be inconsistent with current approaches to building a stable and informative generic classification for the Euptychiina, where monophyly, phenotype and ecological information are incorporated in deciding on the most appropriate taxonomy (e.g. Nakahara, Lamas, et al., 2019). This clade not only includes both widespread lowland taxa (e.g. Magneuptychia libye) and rather narrowly distributed montane species (e.g. undescribed Splendeuptychiaspecies), but also some of the most colourful euptychiine species in the genus Caeruleuptychia. Given that generic names should ideally be informative for the recognition of clades by including species with similar phenotypes, in addition to having potential value in predicting unknown biological traits, we refute the idea of a broad generic classification to include all these taxa contained within the clade containing E. ocnus, and instead establish a monotypic genus for this species.
