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).

A new genus of mylagaluid rodent from the Miocene of the Great Basin, Hesperogaulus, is described, and to it two new species, H. gazini and H. wilsoni (type species) are referred. This genus differs from all other genera of later Tertiary mylagaulines in having: large bosses of rugose bone on the anterior end of the nasal bones; lower slope of the occipital bone; and unique separation of the anterior branches of the forked parafossette on the upper premolar.Hepserogaulus n. gen. represents a distinct lineage of mylagaulids that has been separate from other members of the family since the early Barstovian. This genus is geographically limited to the Great Basin. Other later Tertiary genera of mylagaulids show geographic limitations to other parts of the continent as well.

The oribatid mite family Tegoribatidae has been represented in continental North America by the genera Tegoribates and Tectoribates. Herein, I describe a new genus of Tegoribatidae from North America, Protectoribates, and two new species: Protectoribates occidentalis sp. nov., from forest habitats in western North American, and Tegoribates walteri sp. nov., from forest habitats in California, based on adults and immatures. The descriptions of adults of the type species of Tegoribates, T. subniger Ewing, and other North American species, T. americanus Hammer and T. bryophilus Woolley, are expanded and immatures of T. americanus are described for the first time. Immatures of Protectoribates are apheredermous whereas those of Tegoribates are eupheredermous, though retaining centrodorsal setae. Scutozetes Hammer 1952 is transferred from Tegoribatidae to Ceratozetidae after re-examination of type material. I provide a revised diagnosis for Tegoribates and a key to tegoribatid genera and species for North America. Finally, I provide a revised diagnosis for Tegoribatidae based on world genera.

A new halacaroid family, Pezidae, is erected for the new genus Peza, with two new species Peza ops (type species) and Peza daps. P. ops has been widely collected in south-eastern Australia, while P. daps is known only from a single female taken from the gill chamber of a burrowing crayfish, Engaeus fultoni Smith & Schuster (Crustacea : Decapoda : Parastacidae), in the Otway Ranges, Victoria. During winter and spring, females of both species apparently attach their eggs to their hind legs. The Pezidae is regarded as the sister-group of the remaining Halacaroidea.

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

The paramunnid genera Austrosignum Hodgson, 1910 (type species A. glaciale Hodgson, 1910) and Munnogonium George & Strömberg, 1968 (type species M. waldronense George & Strömberg, 1968) are re-diagnosed. Twenty seven species are reviewed. Austrosignum is restricted to two described species, Munnogonium to five described species. The remaining 20 species are placed in the following eight new genera: Boreosignum (type species Austrosignum maltinii Schiecke & Fresi, 1972), Cryosignum (type species Paramunna lunata Hale, 1937), Meridiosignum (type species M. macquariensis sp. nov.), Tethygonium (type species T. quadricuspis sp. nov.), Quetzogonium (type species Austrosignum dentatum Winkler, 1994), Advenogonium (type species Austrosignum fuegiae Doti & Roccatagliata, 2005), Zizzygonium (type species Paramunna magellanensis Winkler, 1994), Kussakinella (type species Austrosignum spinosum Kussakin, 1982).

The harvestman genus Bonea Roewer, 1914 and its type species B. sarasinorum Roewer, 1914 are redescribed based on the type material. In addition, two new species of Bonea from Hainan Island, China, are described and illustrated: B. zhui sp. nov. and B. tridigitata sp. nov. A new species of Lomanius Roewer, 1923 from Yunnan Province, China, is also described and illustrated: L. bulbosus sp. nov.. Keys to the 10 species of Bonea and the six species of Lomanius are provided. Paralomanius Goodnight & Goodnight, 1948 is revalidated from the synonymy of Lomanius, carrying as junior synonym Eulomanius Roewer, 1949, and containing two species from Micronesia (Paralomanius longipalpus Goodnight & Goodnight, 1948) and Philippines (Paralomanius mindanaoensis (Suzuki, 1977) new status). Bonea is transferred from the Ibaloniinae to Podoctinae. These are the first records of named species of Podoctidae from China.
