The middle-derivative, brachypyline oribatid mite family Cepheidae is rather heterogeneous, but many species, even some genera in this family have been poorly diagnosed. Redefinition of hitherto known taxa is, essential for resolving species identity as well as supraspecific systematics. One of such inadequately described species is Cepheus pustulatus (Pearce, 1910), known from Hawaii, which we redescribe here, and a new genus Roycepheus is proposed, based on this species. Relationships of the genus Roycepheus are addressed using the principles of phylogenetic systematics. A table presents the key differences between genera of Cepheidae, and a diagnostic key to adults of these genera, is provided. We discuss the potential synonymies of Sphodrocepheus with Tritegeus, and Reticulocepheus as well as Oribatodes with Cepheus. However, to confirm these synonymies needs redefinition of these genera and examination of types species.

The oribatid mite family Astegistidae is represented in Mongolia by four species in two genera. A new species, Cultroribula taigagica sp. nov., collected from cool temperate forests in Northern Mongolia is described based on adults. In addition, three known species, Astegistes pilosus (C.L. Koch, 1840), Cultroribula dentata Willmann, 1950 and Cultroribula vtorovi Krivolutsly, 1971 are recorded for the first time from Mongolia, which are redescribed along with data on their distribution and ecology. A key to Mongolian species of Astegistidae is given.

Relationships of the oribatid mite genus Propelops, whose members are common in the litter of North American coniferous forests, are assessed using the principles of phylogenetic systematics; characters of both adults and newly discovered immatures are analyzed. The closest relatives of Propelops are among the Phenopelopidae (despite the lack of specialized mouthparts previously used to characterize the family) rather than the Ceratozetidae, as commonly suggested. A new phenopelopid subfamily, Propelopinae, is proposed to include Propelops. The phenopelopid genus Tectopelops Jacot, 1929 is considered a junior subjective synonym of Eupelops Ewing, 1917. Unduloribatidae, most commonly included among the Oribatelloidea, is transferred to the Phenopelopoidea, and new diagnoses are presented for all phenopelopoid family-group taxa.

The oribatid mite family Liacaridae (Acari, Oribatida) is recorded in Vietnam for the first time. Two new species of liacarids of the genera Liacarus and Xenillus are described from Tam Dao National Park, northern Vietnam. Liacarus vietnamensis sp. nov. is similar to L. laterostris Mihelčič, 1954 in the morphology of lamellar cusps (inner teeth well-developed; interlamellar tubercle absent) and in having long interlamellar setae and short notogastral setae, but differs by the directions of lamellar cusps and morphology of bothridial setae. Xenillus tamdaoensis sp. nov. is similar to X. longipilus Pérez-Íñigo & Peña, 1995 in having long notogastral setae, insertion of notogastral setae lm posterior to la, and the presence of an interlamellar tubercle, but differs by the morphology and position of lamellar cusps, size of the interlamellar tubercle and length of interlamellar setae.

To date, the feather mite family Ptyssalgidae (Acariformes: Analgoidea) has been known from a single species associated with hummingbirds (Apodiformes: Trochilidae). Here, based on our collecting in Mexico, we describe (i) a new genus and species, Tyrannoptyssalges striatus gen. n., sp. n., from a passerine host Tolmomyias sulphurescens (Passeriformes: Tyrannidae) and (ii) four new species of the genus Ptyssalges Atyeo and Gaud, 1979 from hummingbirds (Apodiformes: Trochilidae): Ptyssalges amaziliae sp. n. from Amazilia rutila (Delattre) (type host), A. candida (Bourcier & Mulsant) and A. yucatanensis (Cabot), P. anthracothoracis sp. n. from Anthracothorax prevostii (Lesson, R.), P. atyeoi sp. n. from Phaethornis longirostris (Delattre), and P. campylopteri sp. n. from Campylopterus curvipennis excellens (Wetmore). In addition, we redescribe Ptyssalges major (Trouessart, 1887), the type species of the genus, based on newly collected material from the type host, Eutoxeres aquila, from Panama. Standard morphological descriptions of all mite species are supplemented by CO1 barcoding sequence data. In the genus Ptyssalges, CO1 K2P interspecific genetic distances were 11.39–11.89%, while distances between the single species of Tyrannoptyssalges and species of the genus Ptyssalges were 16.34–17.87%. New, amended diagnoses for the family Ptyssalgidae and the genus Ptyssalges and a key to all known ptyssalgid species are provided. Preliminary hypotheses on the origin and ancestral host associations of ptyssalgids are briefly discussed.

Abstract A comprehensive phylogeny of species relationships of the Auchenipteridae is reconstructed here with a large-scale taxon sampling based on combined morphological and molecular datasets. The hypothesized phylogeny includes most species of Auchenipteridae (97 of 124 valid species) and multiple members of siluriform families as an outgroup (32 species) to embrace the diversity of forms among related catfishes. As the first large-scale phylogeny of the Auchenipteridae, comparison between taxa included information from both morphology (264 characters) and mitochondrial and nuclear molecular markers (3490 nucleotides) from five genes: coI, 16S, rag2, myh6 and SH3PX3. Trees were generated under two different optimality criteria (Maximum Parsimony and Bayesian Inference). A new classification for the family is presented herein to bring the taxonomy more in line with the new phylogenetic hypothesis. The strict consensus tree corroborates the monophyly of superfamily Doradoidea, family Auchenipteridae and its two subfamilies, Centromochlinae and Auchenipterinae. The new classification scheme proposes nine tribes in Auchenipteridae, based on the monophyly of major groups in both subfamilies. Centromochlus, Glanidium and Tatia are each recovered as paraphyletic. To maintain a monophyletic classification, some species treated as Tatia and Centromochlus are assigned to genera not previously recognized as valid.

The oribatid mite family Camisiidae is commonly recognized to include four genera and about 100 nominal species, all of which appear to be asexual. Based on adult specimens from Valdivian forest litter in Osorno Province, Chile, we propose a monotypic fifth genus, Paracamisia gen. n., with type species P. osornensis sp. n. This is the first genus of the family that is not represented in the Northern Hemisphere. Like all other known Camisiidae it seems to be asexual. Paracamisia osornensis sp. n. is distinguishable from other camisiids by its shiny, convex notogaster that lacks a suprapleural scissure, and by its large respiratory bothridial saccule. A preliminary analysis suggests that its closest relatives are to be found in the genus Platynothrus.

The oribatid mite family Zetomotrichidae is represented in warm regions of world, including Australia, South Africa, Mexico, South America and across the Palaearctic from southern Europe to Asia, but has been unreported from the USA and Canada. We describe a new zetomotrichid species, Ghilarovus robisoni n. sp., on the basis of adults, the first record of the genus and family from temperate North America. Specimens were collected from dry, usually rocky, vertical microhabitats in forests in southern USA. We provide a revised and expanded diagnosis for adults of Ghilarovus, discuss characters in Zetomotrichidae unique to the family, and provide a key to world Ghilarovus species.

Haplochthoniidae is a small family within the superfamily Cosmochthonioidea and consists of only two genera and 17 species. In this paper a new species, Haplochthonius (Haplochthonius) longiapophysus sp. nov., is described and illustrated based on adult specimens sampled from soil in Sistan and Baluchestan province, southeastern Iran. The new species is characterised by very long prominent rostral apophyses; blade-like prodorsal and notogastral setae; genital plates with six and anal and adanal plates each with four pairs of setae, an1, ad1 and ad2 thicker than other ano-adanal setae; epimeral setation 3-2-2-3; solenidion φ of tibiae I very long, solenidion ω of tarsi I longer than famulus, seta d longer than solenidion on tibiae II and III. The new species is morphologically very similar to Haplochthonius (Haplochthonius) sanctaeluciae Bernini, 1973, however, the most significant differences between them is in the morphology of rostral apophyses and number and size of genital setae. The family Haplochthoniidae is recorded for the first time from Sistan and Baluchestan province. An updated diagnostic key to the adults of known species of Haplochthonius (Haplochthonius) is given.
