Two new species of butterfly (Lepidoptera, Papilionoidea, Lycaenidae) from the Pantepui (Venezuela) are described; Ocaria faurei Bálint, Attal & Costa, sp. nov. and Strymon auyana Bálint, Benmesbah & Viloria, sp. nov. (Lycaenidae: Theclinae: Eumaeini). Notes and data are provided on the representatives of the genera Ocaria Clench, 1970 and Strymon Hübner, 1818 found in the Pantepui and in its adjacent areas in southern Venezuela with a particular focus on endemism. Resumen. Se describen dos nuevas especies de mariposas (Lepidoptera, Papilionoidea, Lycaenidae) de diversas localidades del Pantepui (Venezuela): Ocaria faurei Bálint, Attal & Costa, sp. nov. y Strymon auyana Bálint, Benmesbah & Viloria, sp. nov. (Lycaenidae: Theclinae: Eumaeini). Se proveen datos y anotaciones sobre los representantes de los géneros Ocaria Clench, 1970 y Strymon Hübner, 1818 encontrados en el Pantepui y áreas adyacentes en el sur de Venezuela con particular enfoque en el endemismo. Keywords. Akopán Tepui, Auyán Tepui, Gran Sabana, Ocaria, Ptarí Tepui, Roraima, Strymon, Wokomong, endemism. INTRODUCTION his work is the fifth paper in the series dedi- cated to the Lepidoptera fauna of the Pan- tepui sensu Costa et al. (2014a); the first paper deals with the concept of the Pantepui, its bio- geography, and its butterfly endemism; the fol- lowing parts (Costa et al. 2014b, 2016 and 2017) are devoted to the description of some new taxa discovered during several expeditions carried out in the last ten years. The type locality of the two lycaenid butterfly species we are describing here is Auyán Tepui (Figs. 1–2), which is one of the largest of the Amazonian-Guianan shield tepuis and well known for its exceptional natural beauty, and especially for Churún Merú, better known as the Angel Falls, the highest waterfall in the world. This tepui is known to be inhabited by many endemic biological taxa, including amphibians, birds, reptiles and plants (Celsa Señaris et al. 2009), and amongst them the recently discovered nymphalid butterflies Archaeogramma claritae Costa, 2014 and Perisama tepuiensis Attal & De Marmels, 2012. The lycaenid fauna of Venezuela is poorly known. Special effort is necessary to get even ba- sic knowledge about its diversity (Neild 1996: 11). T
