The last reviewer of the family Sphaeronectidae (Siphonophora, Calycophorae) (Carré, 1968c) considered that it consisted of a single genus, Sphaeronectes, containing five species; three of which had been recently described by himself. For the other two species there had been much nomenclatural confusion in the past, as is herein reviewed. It is considered that for one of these species the name Sphaeronectes koellikeri Huxley (1859) has priority over the name currently in usage, that is S. gracilis (Claus, 1873; 1874). In addition the status of S. brevitruncata (Chun, 1888) is reconsidered and the species considered valid, with S. japonica (Stepanjants, 1967) being considered as a likely junior synonym of it. Three new Sphaeronectes species, S. christiansonae sp. nov., S. haddocki sp. nov. and S. tiburonae sp. nov., are described, and the systematic position of the genus reconsidered in the light of preliminary molecular phylogenetic data.

Molecular Phylogenetic Data

The Australasian spiny trapdoor spiders of the family Idiopidae (subfamily Arbanitinae) are revised at the generic level, using a multi-locus molecular phylogenetic foundation and comprehensive sampling of all known lineages. We propose a new family- and genus-group classification for the monophyletic Australasian fauna, and recognise 10 genera in four tribes. The Arbanitini Simon includes Arbanitis L. Koch, 1874 (61 species), Blakistonia Hogg, 1902 (one species) and Cantuaria Hogg, 1902 (43 species). The Aganippini Simon includes Bungulla Rix, Main, Raven & Harvey, gen. nov. (two species), Eucanippe Rix, Main, Raven & Harvey, gen. nov. (one species), Eucyrtops Pocock, 1897 (two species), Gaius Rainbow, 1914 (one species) and Idiosoma Ausserer, 1871 (14 species). The Cataxiini Rainbow and Euoplini Rainbow include just Cataxia Rainbow, 1914 (11 species) and Euoplos Rainbow, 1914 (12 species), respectively. Two distinctive new genera of Aganippini are described from Western Australia, and several previously valid genera are recognised as junior synonyms of existing genus-group names, including Misgolas Karsch, 1878 (= Arbanitis; new synonymy), Aganippe O. P.-Cambridge, 1877 (= Idiosoma; new synonymy) and Anidiops Pocock, 1897 (= Idiosoma; new synonymy). Gaius stat. rev. is further removed from synonymy of Anidiops. Other previously hypothesised generic synonyms are supported by both morphology and molecular phylogenetic data from 12 genes, including the synonymy of Neohomogona Main, 1985 and Homogona Rainbow, 1914 with Cataxia, and the synonymy of Albaniana Rainbow & Pulleine, 1918, Armadalia Rainbow & Pulleine, 1918, Bancroftiana Rainbow & Pulleine, 1918 and Tambouriniana Rainbow & Pulleine, 1918 with Euoplos. At the species level, the identifications of Eucy. latior (O. P.-Cambridge, 1877) and I. manstridgei (Pocock, 1897) are clarified, and three new species are described: Bungulla bertmaini Rix, Main, Raven & Harvey, sp. nov., Eucanippe bifida Rix, Main, Raven & Harvey, sp. nov. and Idiosoma galeosomoides Rix, Main, Raven & Harvey, sp. nov., the latter remarkable for its phragmotic abdominal morphology. The Tasmanian species Mygale annulipes C. L. Koch, 1842 is here transferred to the genus Stanwellia Rainbow & Pulleine, 1918 (family Nemesiidae), comb. nov., Arbanitis mestoni Hickman, 1928 is transferred to Cantuaria, comb. nov. and Idiosoma hirsutum Main, 1952 is synonymised with I. sigillatum (O. P.-Cambridge, 1870), new synonymy. In addition to the morphological synopses and an illustrated key to genera, molecular diagnoses are presented for all nominal taxa, along with live habitus and burrow images to assist in field identification. The Australasian idiopid fauna is highly diverse, with numerous new species known from all genera. As a result, this study provides a taxonomic and nomenclatural foundation for future species-level analyses, and a single reference point for the monographic documentation of a remarkable fauna. http://zoobank.org/?lsid=urn:lsid:zoobank.org:pub:BACE065D-1EF9-40C6-9134-AADC9235FAD8

A New Species

Three new species of copepod crustaceans are described from material collected from anchialine and brackish habitats inand around the village of Walengkabola on the coast of Muna Island, to the southeast of Sulawesi. A new species of cy-clopoid, Paracyclopina sacklerae n. sp., was described from material collected from the tidal inflow entering into the bot-tom of sinkholes a few metres inland from the shoreline. Detailed comparisons are made with Paracyclopina orientalis(Lindberg, 1941), n. comb., a closely related congener here transferred from its original genus Cyclopetta Sars, 1913. Theassignment of Paracyclopina Smirnov, 1935 to the family Cyclopettidae is followed here despite uncertainty over the va-lidity of some of the families created by the break up of the former Cyclopinidae. Two new species of Boholina Fosshagen& Iliffe, 1989 are described, based on material from the same sinkholes and from caves located up to 700m inland fromthe coast and exhibiting further reduced salinity down to 1.8 ppt. One species, B. parapurgata n. sp., is very closely relatedto B. purgata Fosshagen & Iliffe, 1989 from Bohol island in the Philippines, the other B. munaensis n. sp., is very closelyrelated to B. crassicephala Fosshagen & Iliffe, 1989 also from Bohol island, but a number of fine scale differences in the leg 5 of both sexes are recognised in each case. Keys to valid species of both genera are provided.

The classification of the Trematode family Opisthorchiidæ presents some difficulties to the systematist. These difficulties arise partly from the fact that a number of the existing species appear to lack any real morphological characters by which they can be differentiated, slight variations in measurements, together with a difference in host, having been considered sufficient to justify the making of new species. This view has resulted in the placing of undue importance on somewhat minor differences when they do occur in other species, such differences being considered sufficient for creating new genera.The systematist is further confronted with the difficulty of forming definite opinions on the systematic position of some of the species made by earlier workers. Their descriptions and figures are often inadequate owing to the fact that characters which, in the past, were considered of minor importance are now given much closer attention. Examples of the confusion which has arisen from such a position will be referred to in this paper.

Abstract The systematic position of the enigmatic genus Squamanita (Agaricales, Basidiomycota) is largely unknown. Together with Cystoderma and Phaeolepiota, they were categorized as belonging in the tribe Cystodermateae. In this study, with newly generated sequences of the type species of the genus Squamanita, namely S. schreieri, and sequences of a few species of Cystodermateae, the phylogeny of this “tribe” is reinvestigated with a concatenated (28S-5.8S-18S) dataset. Our study reveals that Squamanita and Phaeolepiota-Cystoderma are indeed sister groups with moderate statistic support (MLBS/PP = 80/1), and Squamanita is a monophyletic clade with highly statistic support (MLBS/PP = 92/1). The family name Squamanitaceae is resurrected and emended to accommodate the three genera. Meanwhile, another concatenated (ITS-28S-18S) dataset is used to investigate the phylogenetic relationship and species delimitation in Squamanita. Our data indicated that “S. umbonata” from North America, Europe, East Asia, and Central America harbors a complex of species, and species of Squamanita can parasitize species of Amanita, besides other fungal species. Squamanita mira parasitizes A. kitamagotake (A. sect. Caesareae), while S. orientalis and S. sororcula are parasites of species belonging to the A. sepiacea complex (A. sect. Validae). “Squamanita umbonata” from Italy occurs on A. excelsa (A. sect. Validae). Three new species of Squamanita from East Asia, viz. S. mira, S. orientalis and S. sororcula are documented with morphological, multi-genes phylogenetic, ecological data, line drawings, and photographs and compared with similar species.

Generalized Type

The systematic position of the blood-sucking Gamasides Leach, 1815, is still very unsatisfactory. In his work on external parasites, Ewing (1929) recognizes the two families Parasitidae and Dermanyssidae, distinguishing them chiefly by the form of the chelicerae. The former family to which Laelaps and related genera belong is defined by Ewing as follows: ‘chelicerae of a generalized type having the tips incurved and being provided with teeth, and the fixed arm usually bearing a seta near its tip’. The Dermanyssidae have modified chelicerae, ‘usually without teeth and fixed arm always without setae’. In this family Ewing puts the genera Liponyssus, Dermanyssus and related ones.

Taxonomic characters of the adult, pupa and larva of the coconut flat moth, Agonoxena argaula Meyr., are compared with those of the three other known species comprising the family Agonoxenidae, and keys to the species are provided. One new species, A. phoenicia, is described from northern Queensland. The systematic position of the family and the generic status of the four species are discussed. Although differences of possible taxonomic importance have been noted, the species are considered sufficiently homogeneous to allow assignment to the single genus Agonoxena Meyr. Haemolytis miniana Meyr. is transferred to Agonoxena, and Haemolytis Meyr. is suppressed as a junior synonym.

Molecular Phylogenetic

Indochina land snails of the family Ariophantidae are in need of thorough systematic revision. Here we comprehensively revise the systematics of the large-shelled, sinistral (counterclockwise) coiling snails from Thailand and Peninsular Malaysia. Molecular phylogeny based on mitochondrial (coi and 16S) and nuclear (28S) gene sequences demonstrates that these sinistral snails are not members of Dyakiidae as previously thought, but instead are more closely related to the genus Hemiplecta in the family Ariophantidae. Comparative morphology also reveals similarity of reproductive organ features (globular gametolytic organ, well-developed dart apparatus, and lack of amatorial organ complex). Based on this evidence, we propose to transfer these sinistral snails to the genus Hemiplecta. Molecular phylogenetic analyses further strongly support the monophyly of this sinistral lineage with respect to other members of Hemiplecta. This monophyletic clade consists of five members including three species that were previously classified as “Dyakia”, H. lahatensis, H. retrorsa and H. salangana, and two new species described herein, H. ligorica n. sp. and H. thailandica n. sp. This study also suggests that the anatomy of the gametolytic organ in the genus Hemiplecta corresponds well with the phylogenetic relationships and appears to be a taxonomically informative character, while the penial verge has little utility for generic recognition.

Culture Characteristics

The genus <em>Phytopythium</em> is a monophyletic taxon of the Peronosporaceae with characteristics intermediate between <em>Phytophthora</em> and <em>Pythium</em>. In the Philippines, reports of <em>Phytopythium</em> are scarce, with the mangrove-swamp-inhabiting species <em>Phytopythium kandeliae</em> being the only species recorded to date. It was the aim of the current study to investigate the diversity of <em>Phytopythium</em> in mangrove habitats in more detail. Based on culture characteristics, morphology, and molecular phylogenetic position, two new species of <em>Phytopythium</em> are described from Philippine mangroves, <em>P. leanoi</em> USTCMS 4102 and <em>P. dogmae</em> USTCMS 4101. <em>Phytopythium leanoi</em> is a species morphologically similar to <em>P. kandeliae</em>, but with the ability to develop gametangia in a homothallic fashion. The other new species, <em>P. dogmae</em>, is characterized by having a short discharge tube, semipapillate to papillate sporangia and frequently exhibiting a clustering of two sporangia per sporangiogenic hypha. With the addition of the two species described in this study, the genus <em>Phytopythium</em> has grown from around 10 to beyond 20 recognized species over the past decade, and it seems likely that several more species of this genus await discovery.

A new family of early derivative Parasitengona (Acari: Prostigmata), Allotanaupodidae fam. nov., is described from New Zealand based on adults and deutonymphs of two new genera and five new species and a new superfamily Allotanaupodoidea is erected to accommodate it. The new family is characterized by the absence of prodorsal trichobothria and sensory areas, the presence of one or two pairs of plates with multiple setae on C to PS rows of dorsal hysterosoma, the presence of only two pairs of genital acetabula in adults, and short, distally inserted palptarsus on the palptibia. The family consists of two subfamilies (Allotanaupodinae subfam. nov. and Paratanaupodinae subfam. nov.), with the former endemic to New Zealand. Allotanaupodinae subfam. nov. has a single genus, Allotanaupodus gen. nov., which is represented by three new species from New Zealand: Allotanaupodus williamsi sp. nov. (type species) from Kawau I., Auckland, Allotanaupodus orete sp. nov. from Orete Forest, Te Puia Hut and Allotanaupodus winksi sp. nov. from Mt. Messenger, Taranaki. The eyeless Paratanaupodinae subfam. nov. consists of two genera: Nanotanaupodus gen. nov. and Paratanaupodus Andre & Lelievre-Farjon, 1960. The type genus Paratanaupodus Andre & Lelievre-Farjon, 1960 was previously placed in the Tanaupodidae and is represented by a single species, Paratanaupodus insensus André & Lelievre-Farjon, 1960, from South America. Nanotanaupodus gen. nov. is represented by two new species from New Zealand: Nanotanaupodus andrei sp. nov. (type species) from Waituhi Saddle and Nanotanaupodus gracehallae sp. nov. from Orete Forest, Te Puia Hut. A key to superfamilies of terrestrial Parasitengona (post-larval stages) is provided, along with keys to subfamilies, genera and species of the new family.
