Etymology: The species name pays homage to Dr. Paloma Helena Fernandes Shimabukuro, “Instituto René Rachou”, Fiocruz, Minas Gerais for her studies in taxonomy of the American sand flies.
Distribution: BRAZIL. Minas Gerais: Santa Bárbara; Rio Acima (Costa et al. 2021); Pains.
Medical importance: Studies have not yet been conducted on this species regarding vector competence or capacity, or natural infection by parasites.
Comments: Females and males identified as “ Sciopemyia aff. microps ” by Costa et al. (2021) are the same specimens proposed as Sciopemyia shimabukuroae sp. n. in the present study. It is known that the species can be found in caves feeding on anurans (Costa et al. 2021).
