title: A new species of Iapir Py-Daniel, Fonseca & Barbosa (Coleoptera: Myxophaga: Torridincolidae) from Brazil with key to species of the genus.
abstract: The genus Iapir is known only from Brazil, currently with five species. This genus is characterized by the lack of a tooth on the hind margin of metatrochanter and a semi-lunar depression prolonged toward apex of the last ventrite on female specimens. Herein we describe an additional species, Iapir vanini sp. nov., collected in southeastern Brazil in Santa Teresa (type locality), Castelo, and Domingos Martins municipalities, in Espírito Santo State. The presence of a fringe of setae on the anterior face of front tibiae and on the posterior face of hind tibiae, and the male genitalia with an oblique apex in lateral view and bearing tufts of seta on distal third, distinguish this species from other Iapir. A key for identification of the species of Iapir is presented.
