Abstract Knowledge of the morphological features of crayfishes native to New Guinea is limited in many cases, the internal morphology, gastric mills, and mandibles of six species of Cherax species (Decapoda: Astacidea: Parastacidae) from this island were described and illustrated. The measurements were compared with those of parastacid crayfish from Madagascar and New Zealand, with Enoplometopoidea from coral reefs, and Nephropidea from deep sea. Characters peculiar to the family Parastacidae were found both in gastric mills and mandibles, and differences between the morphology of mandibles in freshwater and marine species from the infraorder Astacidea were found. Relationships between functional morphology and feeding behaviour were discussed.

Ascidian Species

Four deep-sea ascidian species collected during the KAVIENG 2014 expedition in Papua New Guinea are described, including additional characteristics not reported previously. Fimbrora calsubia is classified within the family Ascidiidae, Dicopia fimbriata and Octacnemus bythius within Octacnemidae, and Culeolus recumbens within Pyuridae. Anatomical observations confirmed previous descriptions for these four species collected elsewhere. Here, we describe additional morphological features for these species and provide the first barcode DNA sequences (based on a fragment of the mitochondrial gene Cytochrome Oxidase I) for D. fimbriata and C. recumbens.

The first representative of the family Anthomyzidae discovered in New Zealand, viz. Zealantha thorpei sp. nov., is described and illustrated. Zealantha gen. nov. is diagnosed and its relationship to other known genera of Anthomyzidae is discussed on the basis of morphological features including characters of the male and female internal genitalia. Notes on the habitat association and distribution of the new species are given.

Three New Species

Megaxenus Lawence, gen. nov., includes one speciesfrom North Queensland (M. Termitophilus Lawence, sp. nov.) and two from Papua New Guinea (M. bioculatus Lawence, sp. nov. and M. papuensis Lawence, sp. nov.). All three are found in the nests of Microcerotermes species and are the first known termitophiles in the family Aderidae. Notes on the behaviour and life history demonstrate that the larvae are integrated into the termite society, and are incorporated into the trophallactic feeding behaviour of termites, while the adults are actively persecuted by the termites but survive at the edges of the nest because of the webs constructed by the larvae prior to pupation.

A male of the new speciesStygiopontius senckenbergibelonging to the family Dirivultidae Humes & Dojiri, 1980 (Copepoda: Siphonostomatoida) and endemic to deep-sea hydrothermal vents, is described from a raised fault block structure south of Edison seamount of the New Ireland Fore-Arc system (Papua New Guinea). The copepods were collected in by box-corer during cruise SO-133 of the RV ‘Sonne’ at a depth of 1610–1625 m, 3°19′S 152°35′E. The new species belongs to a group of eight species that are separate from 21 congeners on the basis of setation of legs 1 and 4: the coxa of leg 1 has an inner seta (absent on the others) and the third exopodal segment of leg 4 has three outer spines (instead of two spines). The new species shares withS. pectinatusHumes, 1987 a pectinate maxilliped but differs from it in lacking two pectinate, terminal claw-like setae on the endopod of the antenna.

Senior Synonym

A review of the spider family Nicodamidae reveals two subfamilies, Nicodaminae and Megadictyninae, with 29 species. The Nicodaminae contains Nicodamus Simon and six new genera, Ambicodamus, Dimidamus, Durodamus, Litodamus, Novodamus and Oncodamus, from Australia, Papua New Guinea and Irian Jaya. Nicodamus is restricted to N. peregrinus (Walckenaer) and N. mainae, sp. nov.; N. peregrinus is treated as a senior synonym of Theridium semiflavum L. Koch, Centropelma bicolor L. Koch and Ozaleus tarandus Thorell. Ozaleus Thorell is confirmed as a junior synonym of Nicodamus by designation of a lectotype for the type species, 0. tarandus. Durodamus contains one species: D. yeni, sp. nov. (type species). Ambicodamus contains 11 species: A. marae, sp. nov. (type species), A. audax, sp. nov., A. crinitus (L. Koch), comb. nov., A. dale, sp. nov., A. darlingtoni, sp. nov., A. emu, sp. nov., A. kochi, sp. nov., A. leei, sp. nov., A. sororius, sp. nov., A. southwelli, sp. nov. and A. urbanus, sp. nov. Litodamus contains three species: L. hickmani, sp. nov. (type species), L. olga sp. nov. and L. collinus, sp. nov. Dimidamus contains six species: D. dimidiatus (Simon), comb. nov. (type species), D. simoni, sp. nov., D. leopoldi (Roewer), comb. nov., D. arau, sp. nov., D. sero, sp. nov. and D. enaro, sp. nov. Novodamus contains two species: N. nodatus (Karsch), comb. nov. (type species) and N. supernus, sp. nov.; Linyphia meianozantha Urquhart is treated as a junior synonym of N. nodatus. Oncodamus contains two species: 0. bidens (Karsch), comb. nov. (type species) and 0. decipiens, sp. nov. The Megadictyninae, stat. nov., contains two genera from New Zealand, Megadictyna Dahl with M. thilenii Dahl and Forstertyna, gen. nov. with F. marplesi (Forster), comb. nov. Cladistic analysis confirms the division of the family into two subfamilies, and recognises several subgroups within the Nicodaminae: Nicodamus + Durodamus, Ambicodamus + Litodamus, and Novodamus + Oncodamus.

Abstract The Infraorder Astacidea comprises four superfamilies of decapod crustaceans: the freshwater Astacoidea and Parastacoidea and the marine Enoplometopoidea and Nephropoidea. The gill morphology of four species of crayfishes belonging to Astacoidea and Parastacoidea, two coral reef species of Enoplometopoidea, and 2 deep-water species of Nephropoidea are described and illustrated for comparisons and to determine characters characteristic to members of the family Parastacidae (Parastacoidea) from New Guinea. Morphology of the arthrobranchs and pleurobranchs were similar among all species, having a single stem with filament, but podobranchs of the parastacoideans differed from those of Astacoidea, being corrugated and tubular and having filaments. The astacoidean P. virginalis had a plate-like lamella with filament. The two nephropoid and two enoplometopoid species were similar to each other; their podobranch had a flat blade-like lamella without a filament and a shaft with a filament. The gill formulae of the New Guinea species of Cherax were the same as those of the Australian congeners, but the formula of the New Zealand Paranephrops planifronsWhite, 1842 was the same as those of the South American parastacids.
