Until recently, the only sponge-associated genera in the order Zoantharia wereParazoanthus(family Parazoanthidae),EpizoanthusandThoracactis(family Epizoanthidae), both within the suborder Macrocnemina. The taxonomy of the genusParazoanthus,as originally described, has been undergoing revision since 2010, with several species, genera and even families described. In 2015, multiple molecular markers were used in combination with morphological characteristics to erect the genusUmimayanthusinside the family Parazoanthidae. It included three species described from southern Japan, with other records for some of the species from the Great Barrier Reef, New Caledonia and the Red Sea. However, little is known of its distribution in the Pacific Islands. Here we report on the finding ofUmimayanthusspecimens in Palau, Micronesia, representing the first records for this region. A total of 32 specimens ofUmimayanthuswere collected from seven different locations; eight of the specimens were identified asUmimayanthus chanpuru,while the remaining 24 colonies were only identified to genus level.

So far no species of this family of Diptera have been described or recorded from the Samoan Islands. The acquisition of a species of Tabanus by Dr. P. A. Buxton and Mr. G. H. E. Hopkins is therefore of great interest.The Tabanidae of the Pacific Islands undoubtedly form an eastward extension of the family from Papua through Melanesia to Fiji ; various species are known from the Solomons, New Hebrides, New Caledonia, the Loyalties and Fiji, but the family is unrecorded from Tonga or islands to the eastward of Samoa. The Tabanidae thus represent a Papuo-Melanesian element in the Polynesian fauna. It might be mentioned here that two species of Tabanus, T. sidneyensis and T. nigriventris, were described by Macquart from “ Sidney Island,” which has been supposed to be Sidney Island in the Phoenix group. This locality is certainly erroneous ; most of the Diptera described as coming from there are known now to be common Australian forms and these two species are in all probability also Australian. The only other species recorded from Polynesia proper is T. insularis, Walker, described from the Sandwich Islands ; this record is also certainly wrong, since the group is not known to occur in these islands, of which the fauna has been extensively collected.

Homalometron moraveci n. sp. is described from the yellowfin goatfish, Mulloidichthys vanicolensis, from the waters off New Caledonia and from the Swain Reefs of the Great Barrier Reef. Its unique combination of narrow, elongate body and long hermaphroditic duct reaching well into the hindbody, distinguish this species from all other species of Homalometron. A checklist of species of digeneans reported in species of Mulloidichthys shows that most of the records are of members of the Opecoelidae and this is the first record of an apocreadiid from this host genus.

The asellote family Gnathostenetroididae Kussakin, 1967 is reported for the first time from Australian waters. Four new species of Gnathostenetroides Amar, 1957 from the Great Barrier Reef are described. The genus Maresiella Fresi and Scipione, 1980 is here placed into synonymy with Gnathostenetroides and a new diagnosis is given for Gnathostenetroides together with a key to the 12 species and a map of the distribution of the genus. The genus Dignatroides Stock and Vonk, 1990 is placed into synonymy with Caecostenetroides Fresi and Schiecke, 1968, and a new composition of the family Gnathostenetroididae, the updated diagnosis and a key to the three genera are provided.

The shrimp-associated gobiid fish Ctenogobiops maculosus, briefly described by Fourmanoir (1955) from one specimen from the southern Red Sea, is redescribed and illustrated with underwater photographs. A diagnosis is given for the closely related C. crocineus Smith 1959, also with underwater photographs. Ctenogobiops maculosus is presently known only from the Red Sea. Ctenogobiops crocineus is wide-ranging from the Red Sea, and Indian Ocean (type locality, Seychelles), to the western Pacific, with records from the Great Barrier Reef and the Ryukyu Islands. The record of C. maculosus from Taiwan by Thacker et al. (2010) is reidentified as C. crocineus, a first record for the island, and their range extension of C. crocineus to Fiji is confirmed.

Miconia albicans (Melastomataceae), whose common name is canela-de-velha, is a native plant of the tropical region that is abundant in the Cerrado biome. A nematode species was found parasitizing M. albicans, causing severe deformation and gall-like structures on the infected leaves and inflorescences. Morphological, morphometric and molecular characterizations identified the nematode as Ditylenchus gallaeformans. This nematode has great potential as a biocontrol agent of plants in the family Melastomataceae, which are invasive weeds in ecosystems of the Pacific Islands. This is the first report of D. gallaeformans parasitizing M. albicans in the Cerrado of the state of Goiás.

Dry Conditions

Fossil pollen and spores preserved in drillcore from both the upper South Alligator River (SARV) in the Kakadu National Park, Northern Territory and the North-West Shelf, Western Australia provide the first record of plants and plant communities occupying the coast and adjacent hinterland in north-west Australia during the Paleogene 66 to 23million years ago. The palynologically-dominant woody taxon is Casuarinaceae, a family now comprising four genera of evergreen scleromorphic shrubs and trees native to Australia, New Guinea, South-east Asia and Pacific Islands. Rare taxa include genera now mostly restricted to temperate rainforest in New Guinea, New Caledonia, New Zealand, South-East Asia and/or Tasmania, e.g. Dacrydium, Phyllocladus and the Nothofagus subgenera Brassospora and Fuscospora. These appear to have existed in moist gorges on the Arnhem Land Plateau, Kakadu National Park. No evidence for Laurasian rainforest elements was found. The few taxa that have modern tropical affinities occur in Eocene or older sediments in Australia, e.g. Lygodium, Anacolosa, Elaeagnus, Malpighiaceae and Strasburgeriaceae. We conclude the wind-pollinated Oligocene to possibly Early Miocene vegetation in the upper SARV was Casuarinaceae sclerophyll forest or woodland growing under seasonally dry conditions and related to modern Allocasuarina/Casuarina formations. There are, however, strong floristic links to coastal communities growing under warm to hot, and seasonally to uniformly wet climates in north-west Australia during the Paleocene-Eocene.

This paper reports the first record of intersexuality from Porcellana platycheles, a member of the family Porcellanidae. Intersex individuals were identified by the presence of both pairs of genital openings on the coxae of the third and fifth pereiopods respectively, and by morphological characteristics of the abdomen and pleopods. The low occurrence of this condition suggests that intersexuality is due to genetic variations in the population rather than other possible causes of intersexuality previously reported in other decapods.

Eleven Species

Antipatharians are still poorly documented in the southeastern Pacific, with just eleven species reported in Chilean waters, all of them distributed in subtidal areas from 70 to 2000 m depth (Häussermann & Försterra, 2007; Cañete & Häussermann, 2012; Araya et al. 2016a). Among the family Schizopathidae Brook, 1889, which is characterized by polyps elongated in the direction of the axis and having a transverse diameter of 2 mm or more (Opresko, 2002), the recently described deep-water genus Alternatipathes Molodtsova & Opresko, 2017, encompasses two recognized species, Alternatipathes alternata (Brook, 1889), reported from abyssal basins (2670 to 5089 m depth) of the Indian and Pacific Oceans, and Alternatipathes bipinnata (Opresko, 2005), known from a few specimens collected in deep waters (1130 to 2846 m) off the Pacific coasts of northern Mexico and southern USA (Opresko, 2005; Molodtsova & Opresko, 2017).
