RESUMO
Pachyotoma primamexicana sp. nov, from Popocatépetl, Mexico is described; it is similar to Pachyotoma alpa (Christiansen & Bellinger, 1980) and P. muskegis (Guthrier, 1903). It can be distinguished from all other the members of the genus by the small size of PAO (about half the size of closest eye) and the formula (2,3,3) of the slightly capitate tenent hairs. An identification key for Nearctic Pachyotominae and a table with diagnostic morphological characters to the Nearctic species of the genus with integument clearly granulated is given. Three new records of species from Mexico are listed: Pachyotoma crassicauda (Tullberg, 1871), Coloburella octogenaria (Mills & Schmidt, 1957) and Bonetrura boneti (Yosii, 1962). A discussion on the distribution of the subfamily Pachyotominae and some notes on the biogeography of the subfamily are provided.

Here we present a survey of Seira fauna from Iberian Peninsula and Canary Islands, including the description of three new species from Spain: Seira barrai sp. nov., Seira betica sp. nov. and Seira burgersi sp. nov., the latter with unprece-dented antennal morphology for Seira. Five species from Western Europe are redescribed and their dorsal detailed chaetotaxy is revealed for the first time: S. domestica (Nicolet), S. dinizi Gama, S. ferrarii Parona, S. mantis Zeppelini Bellini and S. pini Jordana Arbea, the first two from type locality, and the latter two based on analysis of the type material. A note on chaetal interpretation of the first abdominal segment for Seira is presented. An identification key to 31 species with known dorsal chaetotaxy from Western Palearctic region is also provided, including a discussion on dense macrochaetotaxy present in Palearctic and Oriental species and its reduction in species from others biogeographic regions.

Three new species, Tullbergia rapoporti sp. nov., Dinaphorura nerudai sp. nov. and Dinaphorura najtae sp. nov., and one new record, Tullbergia meridionalis Cassagnau & Rapoport, 1962 are described based on specimens from Tierra del Fuego. Tullbergia rapoporti sp. nov. is similar to T. crozetensis, but can be distinguished from it by the presence of an empodial appendage and the chaetotaxy of Abd VI. Dinaphorura nerudai sp. nov. is diagnosed by the dorsal pso formula, the seven spiniform processes on Abd VI, an elongate PAO, the absence of vesicle on Ant IV and the dorsal chaetotaxy. Dinaphorura najtae sp. nov. is characterised by the dorsal pso formula, the seven spiniform processes on Abd VI, a triangular PAO, the absence of vesicle on Ant IV and the dorsal chaetotaxy.
