Abstract

Eukoenenia igrejinha sp. nov. is described on the basis of one male and one female from the cave Gruta da Igrejinha, state of Minas Gerais, southeastern Brazil. The new species exhibits morphological features unique among the South American species of Eukoenenia described to date, such as a single pair of paramedian thickened setae flanked by one slender seta on each side of opisthosomal sternites IV–VI and 9 pairs of setae on the first genital lobe of the female. Additionally, we provide the coxal formulae of the South American species E. maquinensis, E. spelunca, E. improvisa and E. janetscheki.
