AbstractThe monotypic genus Wawea gen. nov. is described as a second genus in the family Arctomiaceae. The single species, Wawea fruticulosa sp. nov., is characterized by its fruticose habit, rugose and corticate lobes, secondarily multidivided and coalescing apothecia, two-celled spores, and by the unique initial stage of ascocarp ontogeny which includes simultaneous development of ascogonia as well as short-celled, branched conldiophores producing conidia. W. fruticulosa is widespread in Tasmania and is known also from New Zealand with single collections from the North and South Island. A new pyrenomyceteRhynchomeliola lichenicola sp. nov., parasymbiotic on Wawea fruticulosa, is also described.

Two New Species

The discovery of a new genus of Heatherellidae in New Zealand has led us to revise this enigmatic family and its constituent genera. Aheatherella n. gen., based on A. mira n. sp. from the North Island of New Zealand, lacks some of the derived character states that link the Australian Heatherella, most notably the lack of sexual dimorphism in the dorsal shields and in the presence of peritremes in adult Aheatherella. Heatherella osleri n. sp. is described from New South Wales, extending the distribution of this genus beyond Queensland. New collection records of H. callimaulos and a key to the genera and species of the family are provided. We propose that the Heatherellidae—previously placed in its own cohort outside the Gamasina—are best considered a superfamily of gamasine mites within the subcohort Epicriiae.

SummaryCeratitic ammonoids from the Greville Formation in the Nelson Regional Syncline, South Island of New Zealand, were described as a new genus and species of the Ophiceratidae, Durvilleoceras woodmani, and dated as ‘late Middle Permian’ (Waterhouse, 1973). In fact, Durvilleoceras differs from all known Permian ammonoids in both conch form and sutural pattern, but closely resembles lower Triassic ceratites. Structural and sedimentologic complexities within the Nelson Syncline are such that stratigraphic interpretations are questionable, and the fauna of both the Greville and adjacent formations is sparse. Consequently, we consider that Durvilleoceras is best interpreted as a middle Scythian ceratite of the family Flemingitidae.

Octomagelona bizkaiensis (Annelida: Polychaeta), a new genus and species of the family Magelonidae is described from the north-eastern Atlantic. The specimens were collected from the Capbreton Canyon, Bay of Biscay, at a depth of 1000–1040 m. The new genus and species differs from all known genera and species of the family Magelonidae by the presence of eight instead of nine thoracic chaetigers.

New Genus And Species

A new monotypic genus of aorid amphipod Propejanice gen. nov. is described and figured from material collected in Brazil. The single species, P. lagamarensis sp. nov. was collected from artificial plates suspended in the sea in Paraná and Sao Paulo States, Brazil. The new genus appears to be morphologically closest to the genus Janice Griffiths, 1973 from Moçambique, from which it differs in the carpochelate male gnathopod 1. Both genera are phylogenetically close to the genus Grandidierella Coutière, 1904.

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.

Chironex Fleckeri

A series of large Cubomedusae from northern Australian seas-Darwin and north Queensland-has been examined. These are of a single species, described here as Chironex fleckeri, gen. nov., sp. nov. Morphological and systematic studies have been made. It is shown that the system of gonads is markedly different from that obtaining in other Cubomedusae, in which the gonads are leaf-like lamellae that arise at the interradial septum and project into the perradial stomach pouches. In Chironex, only a narrow ridge is present at the interradial septum in the same situation, at most about 0.4 mm wide, and the gonads are lobulated structures that arise alongside the perradial suspensoria, high in the bell cavity, and project into the bell cavity. This structure is also present in the genus Chiropsalmus, but in more primitive form, and in the past has been called the "gastric saccule", of unknown function. It is apparently absent (judging by the literature) in other Cubornedusae. The histology of the gonads and other relevant features in Chironex fleckeri are described. The term "superior gonad" is introduced for what has hitherto been called the "gastric saccule", and the term "lateral gonad" is used for the structure arising at the interradius in the perradial stomach pouches. The systematics of the Cubomedusae are reviewed in the light of the differences in the gonads. The family Chironecldae, fam. nov., is raised for Chironex, gen. nov. The genus Chiropsoides, nom. nov., is proposed for Drepanochirus Krumbach, 1925 (non Pringuey 1901 preoc.), and hence Chiropsoididae, nom. nov., for the family Drepanochiridae Krumbach, 1925. The clinical effects of the stingings of Cubomedusae on man are considered briefly, where relevant. It is probable that Chironex fleckeri is responsible for severe stingings and deaths of humans in northern Austrahan waters, but dlrect proof of this hypothesis is lacking.

A new genus and species of Platyischnopidae from the sandy intertidal of two localities in the north of Chile are described. Ensigeropus cachinalito n. gen., n. sp. is similar to Eudevenopus Thomas & Barnard, 1983 in most characters; however, it presents characters hitherto not reported in the family, as the lobate upper lip and the absence of a mandibular molar. The new taxon is easily recognized among all American Platyischnopidae by the presence of a conspicuous tooth on the posterior margin of the basis of pereopod 7, a character present also in species of the Australian genus Tomituka Barnard & Drummond, 1979.

Gandalfus puia gen. et sp. nov. (Bythograeidae) is reported from submarine volcanoes near the Kermadec Islands. The genus Austinograea is revised with the result that A. yunohana Takeda, Hashimoto & Ohta, 2000 is transferred to the new genus. Both of these species occur in relatively shallow waters (240–1650 m) compared to other bythograeids. A sister group hypothesis of the modern genera, Allograea + (Segonzacia + (Cyanagraea + (Bythograea + (Gandalfus + Austinograea)))) is presented to provide an interpretation of variation in eye regression and male gonopods; Austinograea and Gandalfus are the most derived genera. The pattern of eye regression with depth is discussed. A varunid, Xenograpsus ngatama sp. nov., also collected from these volcanoes, is the first record of this genus from the southern hemisphere. Keys to all known species of the family Bythograeidae (13 species 6 genera) and to the genus Xenograpsus (3 species) are presented.
