Hyphodontia sensu lato, belonging to Hymenochaetales, accommodates corticioid wood-inhabiting basidiomycetous fungi with resupinate basidiocarps and diverse hymenophoral characters. Species diversity of Hyphodontia sensu lato has been extensively explored worldwide, but in previous studies the six accepted genera in Hyphodontia sensu lato, viz. Fasciodontia, Hastodontia, Hyphodontia, Kneiffiella, Lyomyces and Xylodon were not all strongly supported from a phylogenetic perspective. Moreover, the relationships among these six genera in Hyphodontia sensu lato and other lineages within Hymenochaetales are not clear. In this study, we performed comprehensive phylogenetic analyses on the basis of multiple loci. For the first time, the independence of each of the six genera receives strong phylogenetic support. The six genera are separated in four clades within Hymenochaetales: Fasciodontia, Lyomyces and Xylodon are accepted as members of a previously known family Schizoporaceae, Kneiffiella and Hyphodontia are, respectively, placed in two monotypic families, viz. a previous name Chaetoporellaceae and a newly introduced name Hyphodontiaceae, and Hastodontia is considered to be a genus with an uncertain taxonomic position at the family rank within Hymenochaetales. The three families emerged between 61.51 and 195.87 million years ago. Compared to other families in the Hymenochaetales, these ages are more or less similar to those of Coltriciaceae, Hymenochaetaceae and Oxyporaceae, but much older than those of the two families Neoantrodiellaceae and Nigrofomitaceae. In regard to species, two, one, three and 10 species are newly described from Hyphodontia, Kneiffiella, Lyomyces and Xylodon, respectively. The taxonomic status of additional 30 species names from these four genera is briefly discussed; an epitype is designated for X. australis. The resupinate habit and poroid hymenophoral configuration were evaluated as the ancestral state of basidiocarps within Hymenochaetales. The resupinate habit mainly remains, while the hymenophoral configuration mainly evolves to the grandinioid-odontioid state and also back to the poroid state at the family level. Generally, a taxonomic framework for Hymenochaetales with an emphasis on members belonging to Hyphodontia sensu lato is constructed, and trait evolution of basidiocarps within Hymenochaetales is revealed accordingly.

The otocepheid oribatid mite genus Leptotocepheus Balogh, 1961 is recorded in the Australasian region for the first time. The taxonomic status of the genera Leptotocepheus Balogh, 1961 and Longocepheus Balogh & Mahunka,1966 is discussed, resulting in the recognition of Longocepheus as a subgenus (stat. nov.) of Leptotocepheus and the following recombinations: Leptotocepheus (Longocepheus) australis (Balogh & Mahunka, 1966) comb. nov., Leptotocepheus (Longocepheus) globosus (Grobler, 1995) comb. nov., Leptotocepheus (Longocepheus) longus (Balogh, 1961) comb. nov., Leptotocepheus (Longocepheus) youngai (Mahunka, 1984) comb. nov. A new species of Leptotocepheus (Longocepheus) is described from New Zealand, Leptotocepheus (Longocepheus) neozealandicus sp. nov., which differs from other species of the subgenus by the presence of short, slightly developed prodorsal costulae. Revised generic and subgeneric diagnoses, an identification key and distributions for the known taxa of Leptotocepheus are presented.

Morphological, anatomical and chromosome studies of Hyophila crenulata C, Mull. Ex Dus, Thuidium gratum (P. Beauv) Jaeg., Barbula lambarenensis P. Vard.. Stereophyllum nitense Mitt. and Bryum coronatum Schwaegr from Nigeria, were carried out with a view to bridging some knowledge gaps that exist in their characterization and providing insightful information that could be useful in elucidating their taxonomic status. The morphological and anatomical studies revealed several gametophytic and sporophytic attributes which have not been previously reported and which were diagnostic for the moss species studied. The chromosome studies revealed the chromosome numbers to be Hyophila crenulata n = 4; Thuidium gratum n = 12 (10 + 2 m); Barbula lambarenensis n = 3; Stereophyllum nitense n = 9; and Bryum coronatum n = 10. The study concluded that the details of the morphological and anatomical descriptions as well as the chromosome numbers being reported for the first time in this study for the moss species studied could be very useful in their identification and taxonomic delimitation.

Two species of ostracods new to Patagonia, Argentina, are described. One of them, Riocypris whatleyi sp. nov., is described for the first time, and the second, Riocypris sarsi (Daday, 1902) comb. nov., is reallocated from genus Eucypris to genus Riocypris. Inter- and intra-specific variations in shape, size, and sexual dimorphism were evaluated based on geometric morphometric analysis. Moreover, morphological and morphometric comparative analyses were applied to re-examine living and quaternary specimens recovered from previous studies. Based on these results, a generic reassignment for the Patagonian Eucypris fontana (Jurine, 1820) into the genus Riocypris is proposed. Contributing to the knowledge on the systematic and autecology of this enigmatic species, widely distributed in Patagonia and frequently used in paleolimnological reconstructions, generates science-based evidence for their use as indicator species. Additionally, our results emphasize the usefulness of studying the living representatives (i.e., with valves and appendages) for elucidating the taxonomic status of the individual specimens, especially those present in paleontological records and used as bioproxies in paleolimnological studies.

In addition to a previously published study about Siberian osmiine bees, we here further report records of 19 rarely collected and little known species. Twenty-seven species of osmiine bees are currently known from Siberia. Hoplitis beijingensis Wu, 1987, H. kaszabi Tkalců, 2000, and H. inconspicua Tkalců, 1995 are recorded for the first time for Russia and Hoplitis maritima (Romankova, 1985), Osmia inermis (Zetterstedt, 1838), and O. disjuncta Tkalců, 1995 are new to Siberia. Two species, Hoplitis fulva (Eversmann, 1852) and H. papaveris (Latreille, 1799), are excluded from the list of Siberian bees. The male of Hoplitis daurica (Radoszkowski, 1887) is described for the first time, the taxonomic status of Osmia ephippiata Smith, 1879 is discussed and a lectotype is designated for Hoplitis scita (Eversmann, 1852).

Abstract Few digeneans of the family Fellodistomidae are known from the Russian Arctic seas. The taxonomic status of these species, their life cycles and host range raised recurrent questions, some of which remain unanswered. To revise the species composition and life cycles of fellodistomids in the White Sea, we searched for them in several known and suspected hosts: wolffish, flatfishes (definitive), gastropods of the family Buccinidae (second intermediate) and protobranch bivalves (first intermediate). Species identification was based both on morphology and 28S ribosomal RNA gene sequences. We found Fellodistomum agnotum in the White Sea for the first time. Buccinum undatum was proved to be intermediate host of both F. agnotum and Fellodistomum fellis, and metacercariae of F. fellis were registered from two more buccinid species: Buccinum scalariforme and Neptunea despecta. We also found metacercariae of F. agnotum and F. fellis producing eggs in the second intermediate host. Two fellodistomids were found in protobranch bivalves: sporocysts and cercariae of Steringophorus furciger in Nuculana pernula, and sporocysts with large furcocercous cercariae in Ennucula tenuis. The latter were identified as F. agnotum by molecular analysis; thus, the entire life cycle of this species was reconstructed.
