Article
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 newl...
Article
The taxonomy of the monotypic genus Diguetinus Roewer, 1912 is discussed with a redescription of the only named species. The redescription, illustrations, and photographs are based upon male and female type specimens as well as a pair of more recently collected specimens from a relatively nearby location; both in Jalisco, Mexico. The genitalia are...
Article
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 presen...

An overview of the Arachnida and their study in Iran is provided. Besides ancient poetry, relics (going back to 5,000 YBP), and early medical observations (at least 2,000 YBP), the first published taxonomical observations of arachnids from Iran were in 1807 about scorpions. The superorders Parasitiformes and Acariformes (mites and ticks) have recei...
Article
The 22 species of Opiliones recorded from Iran are known from four families: one species of Dicranolasmatidae, five species of Nemastomatidae, 15 species of Phalangiidae, and a single species of Sclerosomatidae. Five of these are recorded for the first time from the country: Dicranolasma ponticum Gruber, 1998, Opilio nabozhenkoi Snegovaya, 2010, Ph...

The Filistatidae is historically known as a family of asocial spiders. Yet they demonstrate some behaviors that are typical of those species that are communal. Two of these behaviors, egg guarding and spiderling cooperative feeding, were observed in Kukulcania geophila. Alone these actions do not in themselves suggest that this species is social, b...

Three eyeless species belonging to the spider genus Cicurina Menge are known from five caves located south of Austin, Travis County (Texas, United States). Because adult female cave-dwelling Cicurina are not common, and adult males rarely collected, these species were described from a very small sample of individuals (nine females). Recent collecti...
