TL;DR: Three species of fossil smaridid mites (Parasitengona, Smarididae) are described based on postlarval forms, including the first named mites from Bitterfeld amber, and at the same time the first examples of mite species common to both the Baltic and Bitterfield deposits.
Abstract: . Three species of fossil smaridid mites (Parasitengona, Smarididae) are described based on postlarval forms. Fessonia wunderlichi sp. nov., Fessonia grabenhorsti sp. nov. and Fessonia groehni sp. nov. were discovered in Eocene (ca. 44–50 Ma) Baltic amber and the former two also in the probably younger Oligocene (ca. 23–25 Ma) Bitterfeld amber. Although Smarididae has been reported from Baltic (and other) Cenozoic amber localities, these are the first species from this group to be formally described. Fessonia wunderlichi sp. nov. and Fessonia grabenhorsti sp. nov. are also the first named mites from Bitterfeld amber, and at the same time the first examples of mite species common to both the Baltic and Bitterfeld deposits. Fessonia groehni sp. nov. is known from a single specimen originating from the Baltic deposit. Although the thickened hindlimbs seen in Fessonia wunderlichi sp. nov. resemble the modern smaridid genus Kraussiana Southcott, 1961, the structure of the crista metopica implies anothe...

TL;DR: Moldoustium haitlingeri Noei, Saboori & Šundić sp.
Abstract: Moldoustium haitlingeri Noei, Saboori & Sundic sp. nov. (Acari: Erythraeidae) is described from northern Iran and Montenegro. It is the second known species of the genus and was found in soil samples. Also, Hirstiosoma latreillei (Grandjean, 1947) and Fessonia papillosa (Hermann, 1804) (Acari: Smarididae) are reported for the first time from Iran.

TL;DR: A key to larval genera of Smarididae and a key to species of Trichosmaris are given, previously known only from post larval instars.
Abstract: Unlike most terrestrial parasitengone mites (chiggers, erythraeids), known mostly from parasitic and easy-to-collect larvae, smaridid systematics are mainly based on the post larval instar. Larvae are rarely collected, and their biology and host associations are virtually unknown. Here we infer phylogenetic relationships of Smarididae based on 50 morphological characters using both larval and post larval instars, including data on the larval morphology of Trichosmaris obtained through rearing. The subfamily Smaridinae, as currently understood, was recovered paraphyletic: the genus Smaris was rendered as basal smaridid lineage, while the genus Fessonia (Smaridinae) was sister to Hirstiosomatinae, albeit with moderate support. Our analysis suggests that the genus Surasmaris Southcott, 1995 is a junior synonym of Trichosmaris Southcott, 1963 (syn. nov.), and two Sphaerotarsus species should be placed into Hirstiosoma: Hirstiosoma baenai (Mayoral & Barranco, 2017) comb. nov., Hirstiosoma quercus (Yazdanpanah, Saboori & Hakimitabar, 2016) comb. nov. Sphaerotarsus monticolus Southcott, 1997 and S. leptopilus were recovered as independent lineages, and hence, a new genus Southcottiana gen. nov. is proposed to include Southcottiana monticola comb. nov (Southcott, 1997). We describe two new species, Trichosmaris paulensis sp. nov. (adults, larvae) and T. calcarensis sp. nov. (larva), and present the first description of larval T. dispar, the type species of Trichosmaris, previously known only from post larval instars. Based on the above results, we give a key to larval genera of Smarididae and a key to species of Trichosmaris (larval and postlarval instars).
