Nematodes, comprising 17 species, including 3 new genera, 4 new species and 3 putative new species, from the families Chabertiidae, Heligmonellidae, Herpetostrongylidae, Molineidae, Oxyuridae and Spiruridae were collected from the digestive tracts of 31 Paramelomys rubex (Murinae: Hydromyini) from Papua, Indonesia and Papua New Guinea. Mawsonema mokwanensis n. gen., n. sp. differs from all other genera in the Heligmonellidae in the characters of the synlophe, 15 ridges oriented sub frontally in the anterior body, the asymmetry of the bursa, the left lobe larger and the proportions of the dorsal ray. Melomystrongylus somoroensis n. sp. differs from its congener M. sepikensis in the number of ridges in the synlophe and the length of the spicules and female tail. A combination of the characters of the synlophe, 15 ridges oriented 55–60° from the saggital plane, lacking a carene, the asymmetry of the bursa and the proportions of the dorsal rays distinguishes Montistrongylus ingati n. gen., n. sp. from all other helligmonellids. Paraheligmosomoides singauwaensis is redescribed. It can be distinguished from P. amplicaudae n. sp., which has a similar number of synlophe ridges, but of differing proportions by the shape of the female tail and the proportions of the bursal lobes. Paraheligmosomoides ennisae n. sp. is characterized by the number of ridges of the synlophe, the shape of the female posterior end and the trilobed right spicule tip. Parasabanema n. gen., n. sp. differs from other heligmonellid genera in the arrangement and proportions of the 45 ridges and the left lateral dilatation of the synlophe. The herpetostrongylid Paraustrostrongylus paramelomysi n. sp. can be distinguished from its congenerics by a combination of characters including the number of synlophe ridges, the extent of the lateral floats in the female and the length of the proximally twisted spicules. Species richness of this nematode assemblage is similar to that of Melomys rufescens and Uromys caudimaculatus but species composition is not. Ten, including the three putative species, of the 17 species found in this study were unique to P. rubex. Biogeographic distributions within the helminth assemblage were discussed.

Nematodes from four families comprising 18 species identified to species level, six to subfamily level as well as larval and adult heligmonellids and juvenile females of an undetermined family were recovered from eight individuals of Paramelomys levipes and 27 individuals of P. mollis (Muridae: Murinae: Uromys Division) from Papua New Guinea and Papua, Indonesia. Originally all the hosts were registered as P. levipes in the Australian and Bishop museum collections, but the probable identity of the host individuals was decided according to the altitude of the collection sites. A capillariid, Capillaria s. l., a putative species of the Nippostrongylinae and a small number of male and female nippostrongylins could not be identified further. The spirurid Protospirura kaindiensis had been previously reported from Sahulan Old Endemic fauna. The oxyurid Syphacia (Syphacia) dewiae n. sp. differed from all its congeners in having an oval laterally extended cephalic plate with a dorso-ventral constriction, cervical and lateral alae, a female tail up to 1400 long and a spicule up to 102 long. The remaining species, all heligmonellids included the brevistriatin Macrostrongylus ingens and 14 nippostrongylin species. Of these Hughjonestrongylus amplicauda, H. mirzai, H. singauwaensis, and Odilia mackerrasae had been reported previously in species of Paramelomys. Species of Flannerystrongylus and Parasabanema, possibly new species, could not be described further. Flannerystrongylus chisholmae n. sp., a smaller worm, differed from its congener F. abulus in having a spicule to body length ratio of 13.2% and only 6 eggs in utero. Helgenema keablei n. gen., n. sp. differed from the 44 nippostrongylin genera known to date in having a synlophe of 11– 15 small ridges and a left cuticular dilatation supported anteriorly by a single large ridge. Paramelomystrongylus dessetae n. gen., n. sp. differed from all other nippostrongylin genera in having a synlophe of 13–16 ridges with a type A carene supported by 2 hypertrophied ridges and the right lateral ridges larger than the dorsal and ventral ridges. Parasabanema sene n. sp. differed from its congener, P. szalayi, in having a synlophe of 30 ridges. Hughjonestrongylus alisoni n. sp., H. arfakiensis n. sp., H. digianiae n. sp. and H. spratti n. sp. were distinguished from all other species of Hughjonestrongylus and each other by a combination of characters including the number of synlophe ridges, 28, 21–26, 20–23, 22–25 respectively, in the mid body, spicule length, proportions of the ovejector and shape of the female posterior end. The combined helminth assemblage was dominated by heligmonellids, as has been reported for other paramelomys, with eight species as well as the oxyurid being unique to P. levipes and P. mollis. Overlapping of host habitat could account for the similarities of the nematode assemblages recorded for those species of paramelomys that have been studied.

Nematodes from six families, comprising 20 species identified to genus level and three to subfamily level as well as juveniles and a heligmonellid that could not be identified further, were recovered from 34 individuals of Paramelomys platyops, one P. cf playops and one Melomys sp. (Muridae: Murinae: Uromys Division) from Papua Indonesia and Papua New Guinea. Ascaridid larvae, a capillariid, Capillaria s. l., two putative species of the Nippostrongylinae and a small number of heligmonellid males and females, could not be identified further. The rictulariid Pterygodermatites sp. (females only) had not been reported previously from Sahulan Old Endemic fauna while three species, the oxyurid Syphacia longecauda , the molineid Hepatojarakus pyknofasciatus, and the spirurid Protospirura kaindiensis, had. The remaining species, all heligmonellids, included the brevistriatine Macrostrongylus ingens and 14 nippostrongyline species. Of these, Hughjonestrongylus amplicauda, H. singauwaensis, Melomystrongylus sepikensis, Mawsonema mokwanense, Odilia mackerrasae and Parasabanema szalayi had been reported previously. Species of Hasanuddina, Montistrongylus and Sanduanensis possibly as yet undescribed, could not be identified further. Flannerystrongylus abulus n. gen., n. sp. differed from all 41 genera described to date in having a synlophe of 14–16 evenly sized ridges with a sub frontal orientation. Hasegawanema yuroense n. sp. with 21–23 synlophe ridges was distinguished from its congeners by a combination of characters including length of spicule, cuticularisation of the genital cone, the proportions of the ovejector and the size of the eggs. Hughjonestrongylus pervulgatus n. sp., H. vanimoensis n. sp. and H. wanumaensis n. sp. were distinguished from all other species of Hughjonestrongylus and each other by a combination of characters including the number of synlophe ridges 25–30, 18, 22–23 in the mid body respectively, and spicule length, proportions of the ovejector and shape of the female tail. A key to the species of Hughjonestrongylus is provided. Species richness was greater than that recorded for P. lorentzii and P. rubex with about 86% of possible species found, as indicated by bootstrap analysis. The helminth assemblage was dominated by heligmonellids with eight species being unique to P. platyops. Paramelomys lorentzii is found at altitudes up to 1500 m and may provide a link between the lowland P. platyops and the highland P. rubex, thus facilitating the distribution of helminth species held in common.

Abstract. Two new genera and eight new species of benthic foraminifera are described from the shallow water, tropical lagoon of Madang, Papua New Guinea. The new hauerinid genus Pseudolachlanella is characterized by juvenile cryptoquinqueloculine, adult almost massiline arranged chambers, and a slitlike, curved aperture with parallel sides and a long, slender, curved miliolid tooth. Pitella haigi n. gen., n. sp. is a new foraminifera with cryptoquinqueloculine arranged chambers, an almost entirely pitted shell surface (pseudopores) and a rounded aperture with a short simple tooth. Among the other species described as new are four hauerinids and two agglutinated foraminifera All new species described here occur sporadically in the shallow water back- and forereef environments of the lagoon (0–55m), and live infaunally and epifaunally in well-oxygenated, fine and coarse grained biogenic sediments. They are absent in muddy, organic-rich, low-oxygen sedimentary environments within bay inlets where variations of salinity are considerable.

Six new species and three new genera of cocalodine jumping spiders are described. Restricted to New Guinea and nearby areas, the Cocalodinae are basal salticids, outside the major salticid clade Salticoida. The new genera are Yamangalea (type species Y. frewana, new species), Tabuina (type species T. varirata, new species) and Cucudeta (type species C. zabkai, new species). In addition to these type species, described are the new species Tabuina rufa, Tabuina baiteta, Cucudeta uzet, Cucudeta gahavisuka, and Allococalodes madidus. The first description of females of the genus Allococalodes is provided. Natural history observations and photographs of living specimens are provided for all five genera of cocalodines.

A previously unreported radiation of myrmarachnine jumping spiders from New Guinea is described, which, although having few known species, is remarkably diverse in body forms. This clade is the new subtribe Levieina, represented by seven new species in three new genera. WithinLevieagen. n.are three new species,L.herbertisp. n.,L.lornaesp. n., andL.francesaesp. n., all of which are unusual among the myrmarachnines in appearing as typical salticids, not antlike.Papuamyrgen. n.superficially resemblesLigonipesKarsch, 1878 orRhombonotusL. Koch, 1879 as a compact antlike spider, but lacks their laterally-compressed palp and bears an ectal spur on the paturon of the chelicera. Two species ofPapuamyrgen. n.are described,Papuamyromhifosgasp. n.andP.pandorasp. n.Agorioidesgen. n., containingA.cherubinosp. n.andA.papagenasp. n., is antlike, with the carapace sunken inwards (concave) between the posterior lateral and posterior median eyes. Phylogenetic analysis of data from the 28S, 16SND1, and COI gene regions of 29 species of myrmarachnines shows that the three new genera form a clade that is sister to the subtribe Myrmarachnina (Myrmarachnesensu lato), with the subtribe Ligonipedina less closely related.

Genital Structure

Thirty-four new species and five new genera of euophryine jumping spiders from Papua New Guinea are described. Thenew genera are Chalcolemia (type species C. nakanai sp. nov.), Phasmolia (type species P. elegans sp. nov.), Variratina(type species V. minuta sp. nov.), Viribestus (type species V. suyanensis sp. nov.) and Zabkattus (type species Z. brevis sp.nov., plus new species Z. furcatus sp. nov., Z. richardsi sp. nov. and Z. trapeziformis sp. nov.). The other new species belong to the genera Bathippus (B. directus sp. nov., B. gahavisuka sp. nov., B. korei sp. nov., B. madang sp. nov.), Canama(C. extranea sp. nov., C. fimoi sp. nov., C. triramosa sp. nov.), Omoedus (O. brevis sp. nov., O. darleyorum sp. nov., O.meyeri sp. nov., O. omundseni sp. nov., O. papuanus sp. nov., O. swiftorum sp. nov., O. tortuosus sp. nov.), Paraharmochi-rus (P. tualapaensis sp. nov.), Sobasina (S. wanlessi sp. nov.), Thorelliola (T. aliena sp. nov., T. crebra sp. nov., T. joannaesp. nov., T. squamosa sp. nov., T. tamasi sp. nov., T. tualapa sp. nov., T. zabkai sp. nov.) and Xenocytaea (X. agnarssonisp. nov., X. albomaculata sp. nov., X. proszynskii sp. nov.). The genera Pystira and Zenodorus are both considered as juniorsynonyms of Omoedus because of their similar genital structure. Species of these two genera are therefore transferred toOmoedus. Diagnostic illustrations are provided for all new species, and photographs of living spiders are also provided when available.

The key includes eight genera known to occur in Australia and Papua New Guinea. These are Ctenarytaina Ferris & Klyver (type genus), Syncarpiolyma Froggatt, Eriopsylla Froggatt, Blastopsylla Taylor, Anoeconeossa Taylor, Leptospermonastes Taylor, and two new genera, Agelaeopsylla and Cryptoneossa. Keys to the species in Agelaeopsylh, Cryptoneossa and Leptospermonastes are given. Agelaeopsylla contains five new species, A. dividua (type species), A. maculatae, A. corymbiae, A. papuanae (which also occurs in Papua New Guinea), and A. insolita. They feed mainly on Angophora and two 'subgenera' of Eucalyptus (Corymbia and Blakella). The hosts of Cryptoneossa, which contains five new species, C. vulgaris (type species), C. occidentalis, C. triangula, C. minuta, and C. leptospermi, are mainly in the 'subgenera' Monocalyptus and Corymbia of Eucalyptus; some are found on Symphyomyrtus and smaller subgenera, one on Angophora, and one on Leptospermum. Two new species of Leptospermonastes are described; L. maculosipennis and L. fasciata were both collected from Melaleuca spp., a new host for this genus. Eriopsylla and its type species, E. viridis, are redescribed, with one new species, E. malleensis.

Two new monospecific genera of the harpacticoid family Laophontidae T. Scott, 1905 are described here. Apistophonte wasiniensis gen. et sp. n. was found along the Kenyan coast and Propephonte duangitensis gen. et sp. n. along the northern coast of Papua New Guinea. They differ from most other laophontid genera in the absence of sexual dimorphism in the endopods of the swimming legs. At first sight, both new species resemble each other very closely in habitus, integumental ornamentation, chaetotaxy of the swimming legs and absence of sexual dimorphism in the endopods. However, the detailed characteristics of A1, maxilla and male P5 show that the species are not congeneric. The structure of the first antennular segment of Propephonte gen. n. suggests a close relationship with Peltidiphonte Gheerardyn and Fiers, 2006. The exact affinities of Apistophonte gen. n. however remain difficult to assess.
