Of the 10 species of freshwater bryozoans previously reported from Australia, only Fredericella australiensis, Hyalinella lendenfeldi and Lophopodella carteri can be positively confirmed from existing preserved material. From a survey of all known museum collections of freshwater bryozoans comes compelling evidence that a specimen labelled ‘Plumatella toanensis’ is actually Hyalinella lendenfeldi, including the only known statoblasts of this species. Plumatella agilis is recognised tentatively pending new material. Fredericella sultana, Plumatella emarginata and P. repens are not represented by any known specimens, although they are likely to occur in Australia. Hyalinella punctata and Gelatinella toanensis have been previously reported in error. Two other previously misidentified specimens, including Hyalinella vaihiriae, are now reported as new species: Plumatella velata and P. rieki. A taxonomic key is given for Australian freshwater bryozoan species, including species both verified from Australia and others only presumed to occur there.

The study is based on new material from the collections of the Naturalis Biodiversity Centre in Leiden (RNHM) and the Hungarian Natural History Museum (HNHM) and addresses issues in two genera: Epeus Peckham & Peckham, 1886 and Ptocasius Simon, 1885 from Thailand. Both genera are of Asian/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of Epeus (Epeus daiqini sp. nov. (♂♀), Epeus pallidus sp. nov. (♀), Epeus szirakii sp. nov. (♀)) and two new species of Ptacasius (Ptocasius metzneri sp. nov. (♂♀) and Ptocasius sakaerat sp. nov. (♀)). Additionally, we redescribed E. tener (Simon, 1877) and added photographs of morphological characters. The genus Ptocasius is redefined due to the inclusion of 37 species, previously included in Yaginumaella Prószyński, 1979. Relationships and distribution of both genera are discussed in reference to molecular, morphological and distributional data, published by other authors in recent years.

This paper deals with some new material of Iranian harvestmen accumulated during and after 2017. These recent collections yielded 11 species from six families, including five species that had previously been known from Iran, and two families and six species which are established as being new for the fauna of the country. The latter include two newly described species of Phalangiidae, namely Homolophus airyamani spec. nov. (male; Hormozgan Province, southern Iran) and Phalangium martensi spec. nov. (male; Khuzestan Province, southwestern Iran). With the study of new specimens and the recording of previously known material, 28 species from six families of Opiliones are currently known from Iranian territories. The records include one species of Biantidae, one species of Dicranolasmatidae, five species of Nemastomatidae, 19 species of Phalangiidae, and a single species each for Sclerosomatidae and Trogulidae.

Taxonomic revisions are the most reliable pathway in unfolding new species to the world. During such a revision of the genus Lagenandra in Sri Lankan, we came across two new species: Lagenandra kalugalensis and Lagenandra srilankensis from the Wet Zone of Sri Lanka. The two new species were studied in detail and compared with the morphology of the other species described in the genus, and based on field collected data conservation assessments were performed. A detailed description for the two new species and an updated taxonomic key to the Sri Lankan Lagenandra is presented here for easy identification. Recognizing two new endemic members enhances the number of Sri Lankan species of Lagenandra to eleven and global to nineteen. According to the IUCN red data category guidelines, L. kalugalensis qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v) while L. srilankensis qualifies for Critically Endangered category under B1ab (iii, iv) + C2 (a) (i, ii). Hence, immediate conservation measures are imperative.

Seven species of the genus Aulodrilus (Annelida, Clitellata, Tubificinae) are studied, based on new material from Japan. Aulodrilus dentosus sp. nov. is characterized as having tubular atrium, forked or bifid distal ends of dorsal crotchets, but no genital chaetae, and A. aestivus sp. nov. is characterized as having crescent-shaped atrium, median male bursa, and bifid chaetae in the dorsal bundles. Five other congeners are redescribed: A. limnobius Bretscher, A. pluriseta (Piguet), A. pigueti Kowalewski, A. japonicus Yamaguchi, and A. americanus Brinkhurst & Cook. Comparison of taxonomic characters among the 14 species recognized in the genus to date shows that three species differ from other congeners in several features: A. paucichaeta Brinkhurst & Barbour, A. adetus (du Bois-Reymond Marcus), and A. apeniatus Cui & Wang. They are provisionally maintained in the genus.

A recent phylogenetic study revealed a close relationship between chiactine-bearing (family Achramorphidae, order Leucosolenida) and pugiole-bearing (order Baerida) calcaronean sponges as well as new putative taxa within Achramorphidae. In this study, we present a revision of chiactine-bearing sponges based on morphological re-examination of type material and recently collected specimens, in addition to new molecular data for the ribosomal 18S and C-region of the 28S. We provide re-descriptions for all known chiactine-bearing species, and further describe two new species from the Antarctic (Achramorpha antarctica sp. nov. and Megapogon schiaparellii sp. nov.) and two new species and a new genus from the Nordic Seas (Achramorpha ingolfi sp. nov. and Sarsinella karasikensis gen. nov. sp. nov.). The new phylogenetic reconstruction based on ribosomal 18S and C-region of the 28S confirms previous findings about the close relationship of some members of Baerida and the family Achramorphidae of the order Leucosolenida. However, new material and the addition of molecular data from the type species of both taxa would be required to formally propose changes at (sub-)ordinal levels within the classification of Calcaronean sponges.

The genus Trichogorgia (Cnidaria: Octocorallia) is composed of mesophotic gorgonians, and has been traditionally included in the Family Chrysogorgiidae. The family is polyphyletic and in need of generic morphological reassessments. Herein, two new species of that genus are described, based on material deposited in the National Museum of Natural History—Smithsonian Institution. Additionally, we provide a taxonomic key to all species of Trichogorgia, also briefly discussing important characters of the group and closely related taxa.

The aim of this study is to analyse the Nephtyidae from the Gulf of California. Previous studies about the family Nephtyidae from the continental shelf of the Gulf include 21 species of which seven have been synonymized by several authors, so that at present only 14 species are recognized. In this study, 1763 specimens of Nephtyidae from the continental shelf of the Gulf of California were examined. Eight species were identified, from which Aglaophamus longicirrata sp. nov. and Aglaophamus foliosa sp. nov. are newly described. Aglaophamus longicirrata sp. nov. is characterized by the presence of very long dorsal cirri in median parapodia and by having 16 rows of subterminal papillae with 3–7 papillae per row, and a pair of middorsal papillae on the proboscis. Aglaophamus foliosa sp. nov. is characterized by foliaceous long dorsal cirri; the proboscis bears 16 rows of subterminal papillae and an irregular number of papillae per row, from 5 to 15. A taxonomic key is presented for the species of Nephtyidae recorded from the continental shelf of the Gulf of California, including the two new species of Aglaophamus.

Two new species of the genus Megophrys are described from historical collections presented by Malcolm A. Smith to The Natural History Museum, London, in the early twentieth century. These specimens were previously misidentified as Megophrys parva, a widespread Asian species apparently comprised of a species complex. Megophrys damrei sp. nov., from the Bokor Plateau in the Cardamom Mountains of southern Cambodia and Megophrys takensis sp. nov., from Ban Pa Che, Tak Province, in western Thailand, are herein distinguished morphologically from all congeners from their respective and neighbouring countries. These, or further specimens representing either species, do not appear to have been reported on by other authors in the past and the conservation status of the two new species remains to be assessed. An attempt to locate both species at and near their respective type localities was successful for Megophrys takensis sp. nov., allowing the documentation of observations in the wild and live colouration. This study highlights the importance of examining historical museum collections often overlooked in recent decades by modern taxonomists.
