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.

We examined material from two poorly documented areas in Brazil concerning the mayfly genus Thraulodes: Minas Gerais, the largest state in Southeastern Brazil, but also the least studied regarding mayflies; and Tocantins, located in the North-Central area of the country. As a consequence of these efforts, we describe a new species from Minas Gerais based on imagos and nymphs, as well as the nymphs of Thraulodes solstitium Orlando, Salles, Boldrini & Krolow, 2021.

Objective: Both stress exposure and high-fat diet (HFD) are contributors to the alarming prevalence of obesity. Leptin is secreted from adipose tissue and regulates appetite and body weight via the JAK-STAT3 pathway in the hypothalamus; it also regulates the hypothalamic-pituitary-thyroid axis, modulating energy homeostasis. Leptin signaling may be impaired by HFD intake, and here we investigate whether social isolation during the prepubertal period, associated with chronic HFD, can exert long-term effects on metabolic parameters in a sex-specific manner.
