Estatus taxonómico de Talides basistrigata Eaton, 1932 (Lepidoptera, Hesperiidae) y su reincorporación basados en una evaluación integrativa

Talides basistrigata Eaton, 1932, originalmente descrita de Perú, posteriormente fue transferida por Evans (1955) al género Hylephila Billberg, 1820, y considerada como una subespecie de H. phyleus (Drury, 1773), argumentando que basistrigata ocurre en ambientes más secos que los que habita phyleus. Actualmente se mantiene el rango taxonómico propuesto por Evans. El objetivo del presente trabajo es restituir el estatus taxonómico de especie válida para basistrigata con base en un análisis integrativo considerando aspectos morfológicos, ecológicos y genéticos. Se examinó las estructuras genitálicas en ejemplares de basistrigata y phyleus, se obtuvo secuencias del gen mitocondrial COI para ambas especies y se recopiló datos en campo para conocer su comportamiento de oviposición en los alrededores de Arequipa, suroeste de Perú. Como resultado del examen morfológico se halló diferencias notorias entre las estructuras genitálicas de ambas especies, principalmente en los procesos caudales de las valvas, la disposición de las pectinas y la forma del uncus en los machos. Con relación al análisis genético, se halló una distancia genética mayor a 3% entre ambas especies, apoyando así el estatus taxonómico de especie para basistrigata. Adicionalmente, desde una perspectiva ecológica, se registró que ambas especies utilizan distintos mecanismos de oviposición y diferentes plantas hospederas, exhibiendo además simpatría espacial y sincronía temporal en la vertiente occidental de los Andes en Perú. Se redescribe el macho y hembra adultos de basistrigata y se designa su lectotipo.

Talides basistrigata Eaton, 1932, originally described from Peru, was subsequently transferred to the genus Hylephila Billberg, 1820 by Evans (1955) and considered a subspecies of H. phyleus (Drury, 1773), arguing that basistrigata inhabits drier environments than phyleus. Currently, the taxonomic status proposed by Evans is retained. The aim of this study is to reinstate the taxonomic status of valid species for basistrigata based on an integrative analysis considering morphological, ecological, and genetic aspects. Genitalic structures were examined in specimens of both basistrigata and phyleus, mitochondrial COI gene sequences were obtained for both species, and field data were collected to understand their oviposition behaviour in the vicinity of Arequipa city, southwestern Peru. As a result of the morphological examination, notable differences were found between the male genitalia structures of both species, primarily in the caudal processes of the valvae, the arrangement of the pectines, and the shape of the uncus. Regarding the genetic analysis, a genetic distance of greater than 3% was observed between the two species, thus supporting the taxonomic status of species for basistrigata. Additionally, from an ecological perspective, it was recorded that both species employ distinct oviposition mechanisms and different host plants, exhibiting spatial sympatry and temporal synchrony on the western slope of the Andes in Peru. Male and female adults of basistrigata are redescribed, and a lectotype is designated.

'Species' from two different butterfly genera combined into one: description of a new genus of Euptychiina (Nymphalidae: Satyrinae) with unusually variable wing pattern

ABSTRACT Sepona Freitas and Barbosa, gen. nov. is proposed for the Neotropical satyrine butterfly species Euptychia punctataWeymer, 1911 and its junior subjective synonyms Euptychia griseolaWeymer, 1911 and Taygetis indecisa Ribeiro, 1931. The new genus has a distinctive wing pattern and shape of the valvae in the male genitalia, the latter being a unique autapomorphy within the subtribe Euptychiina. Based on molecular data, this genus is not sister to any other single euptychiine genus, instead appearing as the sister to all remaining genera in the Taygetis clade. The present paper illustrates the complexity of the taxonomy of Euptychiina, and the importance of using different sources of evidence in taxonomic studies.

Notes on the geographic distribution and subspecific taxonomy of Sais rosalia (Cramer) (Lepidoptera, Nymphalidae, Ithomiini), including the first records in Paraguay

Notes on the geographic distribution and subspecific taxonomy of Sais rosalia (Cramer) (Lepidoptera, Nymphalidae, Ithomiini), including the first records in Paraguay. This paper provides comments on the subspecific taxonomy and geographic distribution of Sais rosalia (Cramer, 1779) (Lepidoptera, Nymphalidae, Ithomiini), as well as an up-to-date distributional map, complemented with unpublished distributional data based on specimens deposited in the Coleção Entomológica Pe. Jesus S. Moure, Curitiba, Brazil and the Museo de Historia Natural, Lima, Peru. The following synonyms are proposed: Sais rosalia camariensis Haensch, 1905 syn. rev. as junior subjective synonym of Papilio rosalia Cramer, 1779 and Sais rosalia brasiliensis Talbot, 1928 syn. rev. as junior subjective synonym of Sais rosalia rosalinde Weymer, 1890. Additionally, the first country records of Sais rosalia in Paraguay, including the southernmost record of the species, are documented.
