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. nov. (male; Hormozgan Province, southern Iran) and Phalangium martensi spec. nov. (male; Khuzestan Province, southwestern Iran). With the study of new specimens and the recording of previously known material, 28 species from six families of Opiliones are currently known from Iranian territories. The records include one species of Biantidae, one species of Dicranolasmatidae, five species of Nemastomatidae, 19 species of Phalangiidae, and a single species each for Sclerosomatidae and Trogulidae.

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. A list of the 29 currently accepted species (all from Northeastern and Central Asia) is presented along with a list of another four species that their validity and proper inclusion in the genus are questioned (still need to be investigated extensively). Descriptions and redescriptions with many illustrations are presented for two new species and 15 previously described species of Homolophus: H. albofasciatus (Kulczynski, 1901); H. almasyi (Roewer, 1911); H. andreevae Starega Snegovaya, 2008; H. arcticus Banks, 1893; H. asiaticus (Gricenko, 1979a); H. betpakdalensis (Gricenko, 1976); H. charitonovi (Gricenko, 1972); H. chemerisi Starega Snegovaya, 2008; H. chevrizovi Starega Snegovaya, 2008; H. gobiensis Tsurusaki, Tchemeris Logunov, 2000; H. kozlovi sp. nov.; H. martensi (Starega, 1986); H. milkoi sp. nov.; H. nordenskioeldi (L. Koch, 1879a); H. pallens (Kulczynski, 1901); H. silhavyi Starega Snegovaya, 2008; H. tibetanus (Roewer, 1911); H. vladimirae (Silhavý, 1967). New country distributional records are detailed for nine species, not including those for the two new species. Three new combinations with Homolophus (H. almasyi, H. asiaticus, H. charitonovi) are recognized for Opilio almasyi Roewer, 1911, Opilio asiaticus Gricenko, 1979a, and Globipes charitonovi Gricenko, 1972.
