16.9 km 2 is the main island (Lopes and Ulbrich, 2015), and the remaining area is distributed among 20 smaller islands, of which Rata Island is the largest with 0.8 km 2. The archipelago has suffered major ecological disturbances due to several human interventions. In 1737, fortifications were built, and the archipelago was transformed into a penal colony for almost 200 years. During this period, a large part of the native vegetation was devastated while exotic plants and animals were introduced to serve as food (Teixeira et al., 2003; Serafini et al., 2010). The human population in the archipelago increased significantly in 1942 through military occupation (i.e., World War II). Afterwards, significant changes were observed in the archipelago due to: • Several insecticide applications campaigns (i.e., DDT) for mosquito-control; • Wild animal introductions, such as the Teju lizard (Salvator merianae Duméril & Bibron) and the Mocó cavy (Kerodon rupestris Wied-Neuwied); • Release of birds seized in trade fairs and public markets of Recife (i.e., Saffron finch (Sicalis flaveola (Linnaeus)), House Sparrow (Passer domesticus (Linnaeus)), and the White-bellied seedeater (Sporophila leucoptera (Vieillot));
The genus Pityocera Giglio-Tos is revised based on examination of external morphology and genitalia of type material and specimens from Brazilian and foreign institutions. Five currently valid species in three subgenera are recognized: P. (Elaphella) cervus (Wiedemann, 1828); P. (Pityocera) festai Giglio-Tos, 1896; P. (Pseudelaphella) nana (Walker, 1850); P. (Pseudelaphella) nigribasis Fairchild, 1964; P. (Pseudelaphella) patellicornis (Kröber, 1930). Five new species are described: P. (Pseudelaphella) barrosi Gorayeb & Krolow sp. nov. (Brazil: Mato Grosso do Sul); P. (Pseudelaphella) gorayebi Limeira-de-Oliveira & Krolow sp. nov. (Brazil: Maranhão, Tocantins and Bahia); P. (Pseudelaphella) pernaquila Gorayeb & Krolow sp. nov. (Brazil: Pará and Rondônia); P. (Pseudelaphella) rhinolissa Krolow & Henriques sp. nov. (Brazil: Pará, Maranhão, Tocantins, Rondônia, Mato Grosso, Goiás and Mato Grosso do Sul; Bolivia: Santa Cruz); P. (Pseudelaphella) ecuadorensis Buestán & Krolow sp. nov. (Ecuador: Manabí, Guayas, Santa Elena and Loja). We provide diagnosis, descriptions, redescriptions, distribution records, illustrations and discussion for all species, as well as a key for identification of species.
