First recorded cave-dwelling terrestrial isopods (Isopoda: Oniscidea) in Iran with a description of a new species .

Cave-dwelling terrestrial isopods from the province of Kohgiluyeh and Boyerahmad, southwestern Iran, are reported here. These include three accidental and one troglobitic species namely Protracheoniscus gakalicus n. sp., which is also the first recorded troglobitic species from the genus Protracheoniscus. The new species is readily distinguished by the lack of eyes and pigmentation.

Revision of the terrestrial isopods of the subgenus Hemilepistus (Desertellio) Verhoeff, 1930 (Isopoda: Oniscidea).

The terrestrial isopod species of the subgenus Hemilepistus (Desertellio) are revised. Hemilepistus ruderalis (Pallas, 1771), H. heptneri Borutzky, 1954, H. pavlovskii Borutzky, 1954 and H. fedtschenkoi (Uljanin, 1875) are redescribed and their diagnostic characters are figured. Three species namely H. nodosus Budde-Lund, 1885, H. zachvatkini Verhoeff, 1930 and H. buddelundi Borutzky, 1945 are synonymized with H. fedtschenkoi, and H. russonovae Borutzky, 1945 is considered as a synonym of H. ruderalis. An identification key to Desertellio species is provided.

Terrestrial isopods of the family Eubelidae Budde-Lund, 1899 from Iran, with description of a new species (Isopoda, Oniscidea).

In the present work, terrestrial isopods of the family Eubelidae are investigated in Iran. The genera Periscyphis and Somalodillo are reported for the first time. More localities are presented for Koweitoniscustamei (Omer-Cooper, 1923) while K.shafieii Kashani, sp. n. is described and figured. A map indicating the sampling localities for the species is presented.

Iranian terrestrial isopods of the family Cylisticidae Verhoeff, 1949 with a description of a new species (Isopoda, Oniscidea).

In the present study, the terrestrial isopods of the family Cylisticidae in Iran are investigated. Geographical distributions of two formerly reported species from Iran, namely Cylisticoides angulatus Schmalfuss, 2003 and Cylisticus rotundifrons (Schmalfuss, 1986), are expanded. Cylisticus masalicus sp. n. is described and its diagnostic characters are figured.

First record and redescription of the terrestrial isopod Hemilepistoidesmesserianus Borutzky, 1945 (Isopoda, Oniscidea) from Iran.

In the present study, Hemilepistoidesmesserianus Borutzky, 1945 is reported from Iran for the first time. This species is redescribed and diagnostic characters of both males and females are illustrated. This species is characterized by the tuberculation of all parts of the dorsal surface of the body and the male pleopod endopodite I with a triangular lobe at apex. A map with the distribution of species is presented.

The agnarid terrestrial isopods (Isopoda, Oniscidea, Agnaridae) of the province of Qazvin, Iran, with a description of a new species.

Six species of terrestrial isopods from the province of Qazvin, central Iran, are recorded. Three species, Hemilepistusklugii (Brandt, 1833), Protracheoniscusehsani Kashani, 2014 and Mongoloniscuspersicus Kashani, 2014, were previously reported from the province. Hemilepistuselongatus Budde-Lund, 1885 and Protracheoniscusmajor (Dollfus, 1903) are recorded for the first time, and one species, Protracheoniscussarii sp. n., is described as new. The diagnostic characters of the new species are figured.

Description of two new species and redescription of one species of agnarid terrestrial isopods (Oniscidea, Agnaridae) from western Iran.

The present study reports on three species of terrestrial isopods from western Iran. The genus Mongoloniscus Verhoeff, 1930 is recorded for the first time from Iran, with description of a new species: M. persicus sp. n. Protracheoniscus ehsani sp. n. is described and P. darevskii Borutzky, 1975 is redescribed based on Iranian specimens. The diagnostic characters of these species are figured and their geographical distribution is presented on a map.

Discovery of Hemilepistus elongatus Budde-Lund, 1885 (Isopoda, Oniscidea) in Iran: redescription and intraspecific character variability.

In the present study, Hemilepistus elongatus Budde-Lund, 1885 is reported from Iran for the first time, redescribed and its diagnostic characters are figured. This species reveals a high variability in morphological characters. The division of the species at the subspecific level can not be supported anymore. This species differs from other species of the genus by the unique shape of male pleopod-endopodite I.
