A new species of the genus Tenuipalpus Donnadieu, 1875 (Acari: Trombidiformes: Tenuipalpidae), namely Tenuipalpus etemadiisp. nov. from Aerva sp. (Amaranthaceae) and Phragmites australis (Poaceae), is described from Iran (Kerman Province). This species belongs to the caudatus species group, bakeri subgroup. This subgroup is briefly reviewed, and a strong biogeographic pattern noted: those species that are also considered part of Tenuipalpus sensu stricto or are close to it, are almost entirely Nearctic (15/16 species), while the remaining 21 species are generally Palaearctic, with just one species from the Nearctic region.

Two new tetranychine spider mites are described from Astragalus in Iran: Tetranychus neosalsolaesp. nov. and Augeriflechtmannia astragalussp. nov. The possible close relationship between the new species prompted us to review the genus AugeriflechtmanniaKoçak & Kemal, 2008—formerly DiplonychusAuger & Flechtmann, 2003. We refine the genus diagnosis and move Tetranychus armeniacaBagdasarian, 1951 and Tetranychus iraniensis Mahdavi & Ueckermann, 2013 to Augeriflechtmannia and discuss the possible synonymy of these species. The genus now comprises five species from Armenia, Iran and Tunisia. [ABSTRACT FROM AUTHOR]

Three new species of the genusFavognathusLuxton, 1973 are described from Iran, namelyFavognathus esfahaniensissp. nov., collected from soil under lichen at Najaf Abad, Esfahan Province;Favognathus alvandiisp. nov., from soil under plum, hawthorn and quince trees at Hamedan, Hamedan Province; andFavognathus guilanicussp. nov., from soil under an unknown plant at Rasht, Guilan Province. The female and male of the type speciesCryptognathus lagenaKramer, 1879 are re-described.Cryptognathus sternalisKrantz, 1958 is removed from synonymy withC. lagenaafter examination of the ornamentation and leg setation of type specimens, because trochanter I has 1 seta and tarsi I–IV 15(1ω)–12(1 ω)–9(1ω)–9(1ω) inC. lagenainstead of trochanter I nude and tarsi I–IV 15(2ω)–12(2 ω)–10(1 ω)–10(1ω) inC. sternalis. http://zoobank.org/urn:LSID:zoobank.org:pub:D801D0D7-2B02-4D0C-91E7-0ED50C8B89D8 [ABSTRACT FROM PUBLISHER]
