One Hundred Years of Solitude: rediscovery of Catasticta lycurgus (Godman amp; Salvin, 1880), a yellow butterfly from the Sierra Nevada de Santa Marta, Colombia (Lepidoptera: Pieridae).

Catasticta lycurgus is a striking endemic butterfly, restricted to high elevation habitats in the Sierra Nevada de Santa Marta, an isolated mountain range separate from the Andes in the north of Colombia. The type, which for almost a hundred years was the only known specimen, was collected in 1878 by Frederick Simons in the vicinity of Atánquez and was sent to the UK to be described by renowned naturalists Godman and Salvin in 1880. In 1972, explorers Adams and Bernard collected a second specimen of C. lycurgus in the locality of San Pedro at 2,900m of elevation in the Sierra Nevada de Santa Marta. These two specimens were the only known ones for many decades until recently, when Colombian entomologists found the species again in San Pedro de la Sierra and later, when a female was discovered in 2013. Here, we report the rediscovery of this rare and charismatic species, with new specimens collected near the type locality, which have not been reported previously. The female of C. lycurgus is described and illustrated for the first time as well the male genitalia of this species. We combine all information available to provide some insights on the systematic relationships of this species within the genus Catasticta Butler, discuss its distribution and provide a preliminary conservation assessment. Despite the newly collected specimens, the species remains very rare in the field and in collections.

Two new species of Euptychia Hübner, 1818 from the upper Amazon basin (Lepidoptera, Nymphalidae, Satyrinae).

Two new species of Euptychia Hübner, 1818 are described from the upper Amazon basin: Euptychia attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (type locality: Amazonas, Venezuela), and Euptychia sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (type locality: Acre, Brazil). Their unusual facies prompted molecular and phylogenetic analyses of one of the species resulting in support for their classification in monophyletic Euptychia. Diagnostic characters for the two species are presented based on wing morphology, wing pattern, presence of androconial patches on the hindwing, and genitalia. Our results indicate that the projection of the tegumen above the uncus, previously considered a synapomorphy for Euptychia, is not shared by all species in the genus. The adults and their genitalia are documented, and distribution data and a map are provided.

ResumoDuas novas espécies de Euptychia Hübner, 1818 são descritas da bacia do alto Rio Amazonas: Euptychia attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (localidade tipo: Amazonas, Venezuela), Euptychia sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (localidade tipo: Acre, Brasil). Suas aparências não usuais levaram a análises molecular e filogenética de uma das espécies que sustentam sua classificação como Euptychia. São apresentados caracteres diagnósticos para as duas espécies baseados na morfologia e no padrão de coloração de suas asas, presença de manchas androconiais nas asas posteriores e suas genitálias. Os resultados indicam que a projeção do tegume sobre o unco, previamente considerada uma sinapomorfia para Euptychia, não é compartilhada por todas as espécies do gênero. São ilustrados os adultos e suas genitálias, bem como dados e mapa de distribuição.

ResumenSe describen dos nuevas especies de Euptychia Hübner, 1818 para la cuenca alta del Río Amazonas: Euptychia attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (localidad típica: Amazonas, Venezuela) y Euptychia sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (localidad típica: Acre, Brasil). Sus apariencias inusuales motivaron el análisis molecular y filogenético de una de las especies, lo cual sustenta su clasificación como Euptychia. Se presentan caracteres diagnósticos para las dos especies basados en la morfología y patrón de coloración alar, presencia de parches androconiales en las alas posteriores y sus genitales. Los resultados indican que la proyección del tegumen sobre el uncus, previamente considerada una sinapomorfía para Euptychia, no es compartida por todas las especies del género. Se ilustran los adultos y sus genitales, y se proporcionan datos y mapa de distribución.
