A review of the Iranian species of the family Onychiuridae (Collembola, Poduromorpha), with description of five new species from Hyrcanian Forests in Iran.

Five new species from different tribes of the family Onychiuridae, namely Heteraphorura kaprusi sp. nov. (Hymenaphorurini), Deuteraphorura dashtenazensis sp. nov. and Onychiuroides mazandaranensis sp. nov. (Onychiurini), Protaphorura hyrcanica sp. nov. and P. iranica sp. nov. (Protaphorurini), from different Caspian Hyrcanian Mixed Forests in the Northern Iranian province of Mazandaran are described and illustrated. H. kaprusi sp. nov. belongs to the oriental species-group of the genus characterized by granulated vesicles in PAO, D. dashtenazensis sp. nov.-to the group of Deuteraphorura species with 1+1 pso on Th. I, and with 3+3 pso on the posterior part of head and Th. II-Abd. III tergites, O. mazandaranensis sp. nov.-to the group of Onychiuroides with 4 papillae and 5 chaetae on AIIIO, P. hyrcanica sp. nov. and P. iranica sp. nov.-to the group of Protaphorura species with 3 pso on Ant. base, 2+2 pso on Th. II and subcoxae 1 of legs II-III without pso. In addition two other species have been found in the same forests: Protaphorura sakatoi (Yosii, 1966) and Protaphorura golestanica Kaprus', Shayanmehr Kahrarian, 2017 (second record of the species). An identification key of the 30 species of Onychiuridae recorded so far from Iran is given.

A new species of Odontella from Tierra del Fuego and notes on Afrodontella Deharveng, 1981 (Collembola: Odontellidae).

Odontella rapoporti sp. nov., from Tierra del Fuego is described, as the third species of the Odontella lobata group, which has a subantarctic distribution. The new species is similar to O. lobata and O. setosa, but can be distinguished from them by the number of chaetae on the dens (6 or 7 chaetae in O. setosa vs. 5 chaetae in the other species) and the number of chaetae in the distal whorl of the tibiotarsus (9 chaetae in O. lobata vs. 11 in the other species). The closely related monotypic genus Afrodontella Deharveng, 1981, and its type species (A. septemlobata) are described.

Simonachorutes, a new genus of Pseudachorutinae (Collembola, Neanuridae) from Europe.

Simonachorutes gen. nov. a new genus of subfamily Pseudachorutinae is described from Europe. It has a unique suite of morphological characters (8 + 8 ocelli, very long buccal cone, mandibles absent, tibiotarsal chaetotaxy reduced, furcula present) and is similar to Pseudachorutes Tullberg, 1871, Paranurida Skarzynski & Pomorski, 1994 and Pongeia Najt & Weiner, 2002. S. romeroi comb. nov. and S. agrensis comb. nov. are redescribed and S. weinerae sp. nov. from Poland is described.

Three new species and one new record of Tullbergiidae (Collembola: Onychiuroidea) from Tierra del Fuego.

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.

The genus Folsomides Stach (Collembola, Isotomidae) in Kermanshah Province (W Iran) with the description of two new species.

The genus Folsomides Stach, 1922 is represented by four species in the Iranian fauna, two of which are new to the science. Folsomides halshinicus sp. nov. and Folsomides subvinosus sp. nov. are found in Kermanshah Province (Western Iran). The new species belong to the Folsomides angularis (Axelson, 1905) group and they are distinguishable from other congeneric species by the macrochaetotaxy (11/22233 macrochaetae on thoracic II to abdominal V tergites) and the number of chaetae on dens. A table with the diagnostic characters for the identification of Iranian species of Folsomides is given. Some figures of F.vinosus Fjellberg, 1993 from Canary Island was given after study of type specimens.

Collembola Poduromorpha from Guelma Province (Northeastern Algeria), with description of a new Superodontella species (Collembola: Odontellidae).

Ten Poduromorpha species have been found in the Taya Region, three of which are new for Algeria: Hypogastrura vernalis (Carl, 1901), Xenylla brevisimilis mediterranea Gama, 1964 and Superodontella tayaensis sp. nov. The new species is morphologically closest to S. subalpina Arbea, 1990, with three subequal dental chaetae. They differ in the number of tibiotarsal chaetae and the sensilar chaetotaxy of Ant IV.
