Further studies on harvestmen (Arachnida: Opiliones) from Iran, with the descriptions of two new species.

This paper deals with some new material of Iranian harvestmen accumulated during and after 2017. These recent collections yielded 11 species from six families, including five species that had previously been known from Iran, and two families and six species which are established as being new for the fauna of the country. The latter include two newly described species of Phalangiidae, namely Homolophus airyamani spec.

Review and contribution to the stonefly (Insecta: Plecoptera) fauna of Azerbaijan.

Known Plecoptera data published from Azerbaijan are critically reviewed. New records of 28 species are enumerated on the basis of specimens collected between 2017 and 2019, among them 16 are new for the fauna of Azerbaijan. Nemoura irani Aubert, 1964 is new for the whole Caucasian region, Leuctra sanainica Zhiltzova, 1960 and Plesioperla sakartvella (Zhiltzova, 1956) are new for the Greater Caucasus.

Further studies on harvestman genus Homolophus (Opiliones: Phalangiidae), with descriptions of two new species.

A key to the members of the subfamily Opilioninae is presented, including the genus Homolophus. That same genus is briefly reviewed, diagnosed, and redescribed based upon a study of approximately half of the described species. Many older museum specimens from the Zoological Institute (Saint-Petersburg, Russia) were identified and all species present were redescribed.
