Mendonça, Maria Cleide deQueiroz, Gabriel Costa

A new species of Collembola, Mucrosomia alticola sp. nov., is described and illustrated based on material from “Parque Nacional da Serra dos Órgãos” (State of Rio de Janeiro) and from “Parque Nacional da Serra do Caparaó” (State of Minas Gerais). This is the first record of a species of Mucrosomia for Brazil. The genus has, up to date, only three species and can be diagnosed by the absence of eyes and pigmentation, PAO present, tenent hair pointed, Abd V and VI fused, manubrium with 1+1 chaetae on anterior side, long dens and a remarkable mucro with five teeth. The presence of chaetae on ventral thorax, between segments II-III, supports the new species.(AU)
