Taxonomic revision of the genus Panca Evans, 1955 (Hesperiidae: Hesperiinae: Hesperiini: Moncina) with the description of two new species.

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

Two new Andean species of Alychna Grishin, 2019 (Hesperiidae, Hesperiinae, Hesperiini, Moncina) from Bolivia and Peru.

Two new species of Alychna Grishin, 2019, Alychna chulumani Medeiros, Dolibaina O. Mielke sp. nov. from Bolivia (La Paz, Chulumani) and Alychna argenteus Medeiros, Dolibaina Casagrande sp. nov. from Peru (Huánuco, Carpish) are described. Illustrations of the wing pattern, forewing stigma and male genitalia of the two species are provided.

Taxonomic revision of the genus Tarmia Lindsey, 1925 stat. rev. (Hesperiidae: Hesperiinae: Hesperiini: Moncina) with the description of a new species from the Andes.

The genus Tarmia Lindsey, 1925, long considered a junior synonym of Phanes Godman, 1901, is here revised and its status is revalidated based on morphological evidence. Two Andean species are included in Tarmia: the type species, T. monastica Lindsey, 1925 comb. rev., and a new species herein described, Tarmia greeneyi A. Warren, Medeiros, Dolibaina O. Mielke sp. nov., from Ecuador, Peru and Bolivia. The male's symmetrical valvae and aedeagus with a twisted median portion, and the very wide ductus bursae of the female genitalia support Tarmia as valid genus apart of Phanes. Illustrations of the main diagnostic characters of both sexes and a distribution map are provided for the species of Tarmia.

Taxonomic revision of Artines Godman, 1901 (Hesperiidae: Hesperiinae: Moncini) with the description of nine new species.

The genus Artines Godman, 1901 and its respective species are revised. The results shows that Artines consists of 15 species distributed from Mexico to Bolivia, Paraguay, southern Brazil and northern Argentina. Nine new species are described: Artines panama Medeiros Carneiro sp. nov. from Panama, Artines solange Medeiros O. Mielke sp. nov. from Brazil (Maranhão), Artines delfos Medeiros Casagrande sp. nov. from Brazil (Amazonas), Artines litoralis Medeiros Dolibaina sp. nov. from Brazil (from Paraíba to Espírito Santo), Artines liege Medeiros, O. Mielke Casagrande sp. nov. from Brazil (central region of Brazil, from Pará to Paraná), Argentina (Misiones) and Paraguay (Alto Paraná), Artines bamba Medeiros O. Mielke sp. nov. from Brazil (Acre and Amazonas) and Peru (San Martin and Madre de Díos), Artines angelica Medeiros sp. nov. from Brazil (Acre, Pará, Maranhão and Mato Grosso), Peru (Madre de Díos) and Bolivia (La Paz), Artines cofus Medeiros Dolibaina sp. nov. from Brazil (Acre and Rondônia) and Peru (Madre de Díos and San Martin) and Artines donia Medeiros Carneiro sp. nov. from Brazil (Rondônia and Goiás). A neotype for Thracides aepitus Geyer, 1832 and a lectotype for Artines atizies Godman, 1901 are designated. Genitalia of both sexes are illustrated and distribution maps for all species are provided. The females of Artines aepitus (Geyer, 1832), Artines focus Evans, 1955 and Artines aquilina (Plötz, 1882) are illustrated for the first time. An identification key is provided for males.
