Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates. Key words: chitons, Leptochiton, Terenochiton, new species, the Philippines, Japan, Papua New Guinea. Описаны два новых вида семейства Leptochitonidae, Leptochiton pumilus sp. nov. и Terenochiton nomurai sp. nov. из тропических и субтропических мелководий западной Пацифики. L. pumilus c Филиппин и Папуа – Новой Гвинеи имеет сетчатовидную скульптуру на раковине, что является довольно редким признаком в этом роде. В этом роде только три вида известны до настоящего времени в тропических мелководьях, в противоположность более чем 130 другим современным видам, которые живут в глубоких холодных водах и в высоких широтах. T. nomurai из островов Рюкю является вторым представителем рода Terenochiton Iredale, 1914, который был недавно восстановлен для Leptochiton norfolcensis (Hedley et Hull, 1912) и характеризуется наличием рудиментов инсерционных пластинок на всех щитках. T. nomurai сходен с типовым видом рода, но отличается расположением пор эстетов на зернах тегментума и менее развитыми рудиментами инсерционных пластинок. Ключевые слова: хитоны, Leptochiton, Terenochiton, новые виды, Филиппины, Япония, Папуа Новая Гвинея.

The genus Cancricepon Giard & Bonnier, 1887 is recorded for the first time from Australia, the Maldives, Papua New Guinea and Taiwan. Four species of Cancricepon are reported here, and two are new to science. Cancricepon choprae (Nierstrasz & Brender à Brandis, 1925) is reported from the Gulf of Mexico on the Florida coast, infesting a new host, Micropanope cf. sculptipes Stimpson, 1871. Cancricepon castroi n. sp. is described from Australia, the Maldives, Japan and Papua New Guinea parasitizing coral crabs of the family Trapeziidae. Cancricepon cf. multituberosum An, Yu & Williams, 2012 is recorded from a specimen of Leptodius affinis (De Haan, 1835) from Taiwan. Specimens previously misidentified as C. choprae parasitizing Scalopidia spinosipes Stimpson, 1858, from China are described as C. beibusinus n. sp. All known hosts and localities of species of Cancricepon are summarized, and a key to the species in the genus is provided. The similarities between species of Cancricepon and the type species of Trapezicepon Bonnier, 1900, are discussed and Trapezicepon thalamitae Markham, 1985, is transferred to Scyracepon Tattersall, 1905.

AbstractThe genus Mitelloides Evans is revised. Three species are recognised and described; M. moaensis Evans (the type species) and two new species, M. thorntonensís and M. mouldsi. A key to the males of the genus is provided, and the known distributions of all species are mapped. The genus is known only from north-east Queensland, the Torres Strait Islands, and Papua New Guinea.

Four new species from three genera of Lebinthina crickets are described here. These include one species of Gnominthus: Gnominthus milneus sp. nov. from Papua New Guinea; two new species of Macrobinthus: Macrobinthus kei sp. nov. and Macrobinthus mamai sp. nov. from Maluka (Indonesia) and Papua New Guinea, respectively; and one species of Microbinthus: Microbinthus elegans sp. nov. from Papua New Guinea.

Litoria graminea is a large green canopy-dwelling frog originally described from a single specimen from an unknown locality in Papua New Guinea. We demonstrate that this species as currently recognised contains at least three distinct taxa. We restrict the name L. graminea to a population of animals occurring south of New Guinea’s main cordillera and describe two new species of large green arboreal frogs, one from the Kikori River Basin (Southern Highlands and Gulf Province) and one from the Huon Peninsula (Morobe Province). The two new species can be distinguished from each other by differences in iris and sclera colouration, and both can be distinguished from L. graminea by their narrower heads, different iris colouration and by their small round (vs elongate) nuptial pads.

Curupirina papuana sp. n. and an unnamed species of a probably new genus of Apistomyiini (Diptera : Blephariceridae) are described from the Ok Tedi, a tributary of the Fly River, Papua New Guinea. This is the first report of the family from the island; its zoogeographical significance is discussed with reference to the long-presumed role of the island in the evolution and dispersal of the tribe Apistomyiini.
