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.

Jumping Spiders

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.

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 Papuan endemic genus Dobodura Darlington is taxonomically revised, with five newly described species — Dobodura alildablldooya sp. n., D. hexaspina sp. n., D. obtusa sp. n., D. svensoni sp. n., and D. toxopei sp. n. — complementing the type species, D. armata Darlington. The sympatric Dobodura alildablldooya and D. svensoni are described from Chimbu Province, Papua New Guinea. Known distributions of the other three new species are: D. hexaspina, Madang Province, P.N.G.; D. obtusa, Olsobip, Fly River, Western Province, P.N.G.; and D. toxopei, Bernhard Camp, Papua, Indonesia. Dobodura is the sole precinctive Papuan genus in an Australian-Papuan clade also including Clarencia Sloane, Dicraspeda Chaudoir, and Eudalia Laporte. Phylogenetic analysis of Dobodura places its known earliest divergence event on the northern New Guinea margin of the Australian craton. Later divergence events result in species occupying island-arc terranes progressively incorporated into present-day northern New Guinea, commencing in the Miocene.

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.

Iphimedia is reviewed and a new diagnosis based on 35 known species is given. Three new species, one each from Australia, Papua New Guinea and Florida, are described. This is the only genus, in a family otherwise confined to cold and deep oceans, that has tropical species.

The Asymmetry

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.
