Abstract

The family Microstigmatidae is composed of two subfamilies, Microstigmatinae and Micromygalinae, seven genera and 16 species. Micromygalinae is monotypic, comprising the species Micromygalediblemma Platnick & Forster, 1982 from Panama. A new genus, Tonton is described as a new member of the Micromygalinae. Masteriaemboaba Pedroso, Baptista & Bertani, 2015, is transferred to the new genus and six new species from Brazil are described and attributed to Tontongen. n.: the type species, T.itabiritosp. n., T.quecasp. n., T.matodentrosp. n. and T.sapalosp. n., all from the state of Minas Gerais; T.ipiausp. n. from the state of Bahia and T.quiteriasp. n. from the state of Maranhão. Among the cavernicolous species, only T.itabiritosp. n. is considered troglobitic by the total absence of eyes.
