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 varying concepts of Janirellidae Menzies, 1956 are outlined, including its rejection by several authors. The view of Wilson and Wägele of Janirellidae being a valid family comprising Janirella Bonnier, 1896 and presumably Dactylostylis Richardson, 1911 (= Spinianirella Menzies, 1962) is accepted. Diagnoses of the Janirellidae subsequent to Menzies’ original one were based on the inclusion of a diverse range of genera now recognised as not belonging in that family. A new diagnosis of Janirellidae is presented based on the inclusion of Janirella, Dactylostylis, and a new genus Triaina with two new species, T. isodonte and T. makridonte, from south-eastern Australia. The latter species represents the shallowest record (80 m) of the otherwise predominantly deep-water family. All species in the family are listed in an appendix, with area of type locality and depth range.

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).

The development of the cephalothoracic grooves, orientation of the chelae in life (correlated with burrowing), and modifications of the sexual characters of the males are the main attributes utilized in deducing the probable phylogeny of the Parastacidae. Geocharax, in which the cephalothoracic grooves are separated and clearly defined, the chelae are orientated in oblique planes, and the male genitalia are simple, is considered to be the most plesiomorphic genus: the species, which are only moderate burrowers, occur in the Bass Strait Basin of south-eastern Australia. The Parastacidae are considered to have originated in this one area of Australia, and to have dispersed from there to the other present day extra Australian regions of the southern hemisphere, each of the four extra Australian genera being the apomorphic sister-group of a genus occurring in this Australian subregion. The new genus Gvamastacus, with two included new species, is characterized by the extraordinarily large genital papillae of the male, and the eniarged pleura of the second abdominal segment of the female. The cephalothoracic grooves and lines are clearly defined and almost as well developed as in Geocharax.

Mode Of Life

The peculiar lebiine genus Disciferella gen. n. is described as a representative of the subtribe Dromiusina Bonelli, 1810. The genus is very distinct habitually and could be easily recognized among other lebiines already by its appearance. In combination of its distinctive features, it is most similar to the enigmatic monotypic genus Brachynopterus, but distinguished from it by several sufficient characters, including the shape of the gonocoxite which is very characteristic (elongate and slightly arcuate) in the latter genus and typical for Dromiusina (short and wide) in Disciferella gen. n. The new genus includes two newly described species: D. kabakovi sp. n. (type species) from Afghanistan and Pakistan, and D. psammophila sp. n. from south-eastern Iran. The very characteristic habitus of the two new species with their wide discoidal elytra is similar to that of some species of the genera Discoptera Semenov, 1889 and Graphipterus Latreille, 1802 living in sandy habitats. This resemblance suggests a similar specialized mode of life, most likely in sandy deserts and dunes. The systematic position of the new genus is discussed.

Four new genera including five new species are described. All are from north-eastern Queensland. Barbaragraecia comprises two new species. B. unicorn Rentz & Su, gen. et sp. nov. (the type species) and B. richardsoni Rentz & Su, sp. nov. Geoffagraecia is known from a single species, G. gwinganna Rentz & Su, sp. nov. the type species. Greenagraecia Rentz & Su, gen. et sp. nov. is known from two species, G. attenuata Rentz & Su, gen. et sp. nov., the type species and G. cooloola Rentz & Su, gen. et sp. nov.. The unrelated genus Nicsara Walker 1869 is discussed and species with falcate ovipositors are removed and placed in a new genus, Larifugagraecia Rentz & Su gen. nov., with Nicsara spuria Redtenbacher 1891 designated as the type species. Two species are removed from Nicsara and placed in Larifugagraecia. These are N. cornuta (Redtenbacher 1891) and N. spuria. Other species remain in Nicsara until they can be further assessed. Biological and ecological notes accompany detailed descriptions of the new species along with many morphological illustrations. Illustrations also are provided for L. spuria gen. nov. A key to the described fully-winged Australian agraeciine genera is provided at the end of the paper.

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 genus and species of janiroidean Asellota, Xenosella coxospinosa, is described from the mid-bathyal slope off the coast of south-eastern Australia. Following a comparison of the new species to several families of broadly similar body shape, with emphasis on monotypic Pleurocopidae, a new family, Xenosellidae, is proposed for the new species. In the course of comparing relevant taxa, the current placements of Prethura Kensley in the Santiidae and Salvatiella Müller in the Munnidae are rejected. The two genera are considered to be incertae sedis within the Asellota superfamily Janiroidea pending further studies.

Two New Species

Recent survey work for planthoppers at La Selva Biological Station in Costa Rica found two new species allied with Cenchrea Westwood. The cytochrome c oxidase subunit I (COI) and 18S were sequenced for the new taxa and used these data to assess the genus-level standing of the new taxa. The new taxa do not cluster with Cenchrea dorsalis Westwood, the type species of Cenchrea. A new genus Tico gen. n. described for the reception of new species described as Tico emmettcarri sp. n. (the type species) and Tico pseudosororius sp. n. Cenchrea sororia Fennah is moved to Tico gen. n., to form the new combination Tico sororius (Fennah). Tico gen. n. is compared with allied genera, and review genus-level diagnostic features and the species composition of Cenchrea, which appears to be compositionally heterogenous, but additional data is needed to evaluate genus-level placement of most species.

We describe a new genus in the mite family Melicharidae, Mycomelichares Mašán & Joharchi gen. nov., to accommodate two new species, Mycomelichares polypori Mašán & Joharchi sp. nov. and Mycomelichares reductus Mašán & Joharchi sp. nov. on the basis of specimens collected on wood-decaying fungi and/or mycophagous beetles of the genera Triplax Herbst and Tritoma Fabricius (Coleoptera: Erotylidae) in Slovakia and European part of Russia, respectively. Moreover, two previously described Proctolaelaps species—P. cyllodi Samšiňák, 1960 and P. slovacus Mašán, 1998 are transferred to the newly established genus. The new genus is characterized by specific characters in tritosternum (enlarged and brush-shaped, having their laciniae thickened, basaly fused and distally densely pilose), chelicerae (slightly dish-shaped digits with long, narrow and sharp denticles), ventral hypostome (setae h1 enlarged, thickened and distally flattened), setation (tendency towards placement of R series setae on soft integument, and reduction of some setae on idiosoma and legs), and unusual ecological specialisation on fungal substrates. Mycomelichares polypori sp. nov. is adapted to the life in sporophores of the basidiomycete bracket fungus, Polyporus squamosus (Polyporaceae). Mites of this species can be abundantly found on the lower fertile surface of the fungus, including large spore-bearing pores. Furthermore, keys to the melicharid genera reported from Palaearct, and the species of the genus are provided.
