Anacroneuria mineira Novaes & Bispo, 2014

Fig. 3A–G

Material examined. BRA: MG, Municipality of Aimorés , Manhuaçú River, 19º29’38.07”S, 41º16’31.73”W, 124 m. a.s.l., light trap, 06–07.i.2022, 14 males, A.Viana, P. Bonfá & P. Rodrigues .

Remarks. The adult was described for the first time in a river from the central zone of Minas Gerais, in the Serra do Cipó ( Novaes & Bispo 2014). Our specimens were also found in a river, Manhuaçú River, with similar proportions to the type-locality. The material examined here presents a considerable variation in size compared to the holotype. The male forewing length of our specimens is 7.5–8.5mm (n=4), while the holotype is 16.1mm. This variation could be due to the difference in elevation between these localities: 761 m a.s.l. in Cipó River, while 123 m a.s.l. in Manhuaçú River. Also, the color pattern varies, being dark brown in our material, and yellowish in the original description. This variation, however, could be related to the fading of the material originally described. Additionally, the shoulders of the penial armature of our material are wider compared to the illustrations provided in the original description ( Novaes & Bispo 2014). This species was described based only on one specimen; therefore, it is necessary to examine more specimens from the type locality in order to obtain more information regarding the status of the individuals from this study. With this new record for the Doce River basin, this species expands its distribution to the east of Minas Gerais.
