Parabrosmolus novaeguineae,a new genus and species of the subfamily Brosmophycinae from Papua New Guinea (Bythitidae,Ophidiiformes)

Parabrosmolus novaeguineae, a new genus and species of the subfamily Brosmophycinae (family Bythitidae) is described, based on a single specimen from Papua New Guinea. The genus is unique in the tribe Brosmophycini in having six branchiostegal rays and ten precaudal vertebrae, and is also similarly distinguished from two brosmophycine genera,Melodichthys andBeaglichthys, tribal allocations of the two latter being uncertain.Parabrosmolus also differs from all other genera in the subfamily by the following combination of characters: head scaly, anal fin origin slightly before midpoint of body, eye diameter shorter than snout length, three developed rakers on first gill arch and 16 (14+2) caudal fin rays.     

Caprellids (Crustacea: Amphipoda) from Papua New Guinea,with the description of a new species

This is the first study of caprellid amphipods from the coast of Papua New Guinea. Several collections from Madang Lagoon (north) and Bootless Bay (south) have been studied. Seven species in seven genera are recorded, of which Pseudoproto papua sp. nov. is described as new to science. The genus Pseudoproto Mayer, 1903 has consisted, so far, of only one species, Pseudoproto fallax Mayer, 1903. Although only a single male has been found of Pseudoproto papua sp. nov., differences in antennae, mouthparts, gnathopod 2 and pereopods 3 and 4 have revealed that it represents a new species of Pseudoproto. Lateral view figures of all species, together with a key to species level for the Caprellidea from Papua New Guinea are also included. Communicated by H.-D. Franke     

A new species of Peucoglyphus Bernhauer from New Guinea (Coleoptera, Staphylinidae, Staphylininae)

Peucoglyphus kensp. n., a new species from New Guinea is described. Adding the new species, this rare Wallacean genus from the tribe Staphylinini (subtribe Philonthina) currently includes five species. An updated identification key for the genus is provided.     

A new Philocheras species (Decapoda,Crangonidae) from Hansa Bay,Papua New Guinea

A new species of crangonid shrimp, Philocheras wilkinsae (Decapoda, Crangonidae) is described from Hansa Bay, Madang Province, Papua New Guinea. The new species belongs to the japonicus group, and can be distinguished from the other members of this group by carapace dentition and carination. The pleopod structure is unique in the genus.     

A new species of Zygina from Papua New Guinea,and records of some leafhopper and planthopper species (Homoptera: Cicadelloidea and Delphacidae)

Abstract

Zygina medioborealis n.sp. is described from silver beet and carrots from Papua New Guinea. Indications are that this species, along with its close allies from Australia, New Zealand, and Norfolk Island, forms an incipient genus radically different from Palearctic and Nearctic Zygina Fieber. A few species of leafhopper and planthopper are listed, with their hosts; Cofana nigrilinea (Stål) is a new record for this locality.     

A new species of Ilyocryptus (Anomopoda: Macrothricidae) from Argentina

I. elegans n.sp. from the Parana River, northeastern Argentina is proposed and its morphological features are compared with those of the apparently related I. agilis. Its outstanding characteristics are the long 2rd to 5th setae of ventral margin of the valves, the rudimentary nature of defensive setae, the low number of spines in the preanal lobe of postabdomen and the unequality of the length of the setae in the outer distal lobe of first trunk limbs.Finding of this new species suggests that I. agilis would be a complex of species and its records should be revised.     

Revision of the termite family Rhinotermitidae (Isoptera) in New Guinea

Recently, we completed a revision of the Termitidae from New Guinea and neighboring islands, recording a total of 45 species. Here, we revise a second family, the Rhinotermitidae, to progress towards a full picture of the termite diversity in New Guinea. Altogether, 6 genera and 15 species are recorded, among which two species, Coptotermes gambrinus and Parrhinotermes barbatus, are new to science. The genus Heterotermes is reported from New Guinea for the first time, with two species restricted to the southern part of the island. We also provide the first New Guinea records for six species of the genera Coptotermes and Schedorhinotermes. We briefly describe soldiers and imagoes of each species and provide a key based on soldier characters. Finally, we discuss the taxonomic and biogeographical implication of our results. A replacement name, Schedolimulus minutides Bourguignon, is proposed for the termitophilous staphylinid Schedolimulus minutus Bourguignon, to solve a question of secondary homonymy.     

A new species of hagfish (Myxinidae: Eptatretus) from Papua New Guinea

A new species of seven‐gilled hagfish Eptatretus astrolabium (Myxinidae) is described from a 400 mm total length female trapped 1 km east from Planet Rock, Astrolabe Bay, Papua New Guinea, at c. 500 m depth. This is the first hagfish species reported from the waters around New Guinea. It can be distinguished from other hagfishes by a combination of characters including seven pairs of gill apertures, three‐cusp multicusps on the anterior and posterior rows of cusps, 10 posterior unicusps, 52 total cusps, 18–19 prebranchial pores, five branchial pores, 48–49 trunk pores, 83–84 total pores and no nasal‐sinus papillae.     

Introduction of the Exocelina ekari-group with descriptions of 22 new species from New Guinea (Coleoptera,Dytiscidae, Copelatinae)

The Exocelina ekari-group is here introduced and defined mainly on the basis of a discontinuous outline of the median lobe of the aedeagus. The group is known only from New Guinea (Indonesia and Papua New Guinea). It contained four species to date: Exocelina astrophallus (Balke, 1998), Exocelina atowaso (Shaverdo, Sagata & Balke, 2005), Exocelina munaso (Shaverdo, Sagata & Balke, 2005), and Exocelina polita (Sharp, 1882). Twenty two new species are described herein: Exocelina alexanderi sp. n., Exocelina anggiensis sp. n., Exocelina arfakensis sp. n., Exocelina bifida sp. n., Exocelina brahminensis sp. n., Exocelina bundiensis sp. n., Exocelina edeltraudae sp. n., Exocelina ekari sp. n., Exocelina eme sp. n., Exocelina evelyncheesmanae sp. n., Exocelina hansferyi sp. n., Exocelina irianensis sp. n., Exocelina kakapupu sp. n., Exocelina knoepfchen sp. n., Exocelina oceai sp. n., Exocelina pseudosoppi sp. n., Exocelina soppi sp. n., Exocelina unipo sp. n., Exocelina utowaensis sp. n., Exocelina waigeoensis sp. n., Exocelina weylandensis sp. n., and Exocelina wondiwoiensis sp. n. The lectotype of Copelatus politus Sharp, 1882 is designated. A checklist and identification key to all species of the group are provided and important diagnostic characters (habitus, color, male antennae and protarsomeres 4–5, median lobes and parameres) are illustrated. Data on the distribution and habitat requirements are given. Representatives of the Exocelina ekari-group are so far mostly known from lowland to lower montane habitats of the northern and central parts of New Guinea, the group is less diverse in higher altitudes.     

A new species of Lesticus Dejean, 1828 (Coleoptera,Carabidae) from the Finisterre Range,Papua New Guinea and a key to the genera of pterostichine-like Harpalinae of New Guinea

Lesticus finisterrae (Carabidae: Pterostichini) sp. n. (type locality: Finisterre Range, Papua New Guinea), is described and characters to differentiate it from other “Trigonotomi” species are given. A key to the genera of pterostichine-like Harpalinae of the island, including all genera of Morionini, Cratocerini, Drimostomatini, Abacetini, Loxandrini and Pterostichini, is provided. The genus Rhytisternus (Pterostichini) is for the first time reported from New Guinea, represented by the likely adventive species Rhytisternus laevis (Macleay). The previously unknown male of Stegazopteryx ivimkaensis Will (Drimostomatini) is described.     

Amphidoma parvula (Amphidomataceae), a new planktonic dinophyte from the Argentine Sea

Amphidoma is an old though poorly studied thecate dinophyte that has attracted attention recently as a potential producer of azaspiracids (AZA), a group of lipophilic phycotoxins. A new species, Amphidoma parvula, sp. nov. is described from the South Atlantic shelf of Argentina. With a Kofoidean thecal plate pattern Po, cp, X, 6′, 6′′, 6C, 5S, 6′′′, 2′′′′, the cultivated strain H-1E9 (from which the type material of Am. parvula, sp. nov. was prepared) shared the characteristic plate arrangement of Amphidoma each with six apical, precingular and postcingular plates. Amphidoma parvula, sp. nov. differs from other species of Amphidoma by a characteristic combination of small size (10.7–13.6 µm in length), ovoid shape, high length ratio between epitheca and hypotheca, and small length ratio between apical and precingular plates. Other morphological details, such as the number and arrangement of sulcal plates and the fine structure of the apical pore complex support the close relationship between Amphidoma and the other known genus of Amphidomataceae, Azadinium. However, Am. parvula, sp. nov. lacks a ventral pore, a characteristically structured pore found in all contemporary electron microscopy studies of Amphidoma and Azadinium. As inferred from liquid chromatography coupled with tandem mass spectrometry, Am. parvula, sp. nov. did not produce AZA in measurable amounts. Molecular phylogenetics confirmed the systematic placement of Am. parvula, sp. nov. in Amphidoma (as sister species of Amphidoma languida) and the Amphidomataceae. The results of this study have improved the knowledge of Amphidomataceae biodiversity.     

Gordionus maori (Nematomorpha: Gordiida), a new species of horsehair worm from New Zealand

Only four species of freshwater Nematomorpha (Gordiida) and one undetermined Gordius sp. are known from New Zealand. During recent surveys in the South Island we discovered a new species belonging to the genus Gordionus, a genus new to New Zealand. Scanning electron microscopic observations of seven collected specimens revealed that the species is clearly morphologically distinct from all other members of the genus and is characterised by the presence of an extensive row of large bristles on the ventral side of the posterior end in males. This row is much larger than in any known Gordionus species. Analysis of the mitochondrial CO1 gene and of the nuclear 18S rRNA gene showed that the new Gordionus specimens form a monophyletic clade, but with partly extensive internal genetic difference. This indicates that cryptic species might be present, for although there are minor variations in cuticular areoles, other morphological characters indicate little difference between specimens.

A new species of the spider genus Naevius Roth from Argentina (Araneae,Amaurobiidae, Macrobuninae)

Naevius calilegua spec. nov. is described from yungas in Jujuy Province, Argentina. Naevius species bear a conspicuous tibial gland, discharging through a movable dorsal tibial apophysis. This character relates Naevius to the macrobunine genera Emmenomma and Anisacate.     

Centaurea amanosensis (Asteraceae), a new species from Turkey

Centaurea amanosensis M. Bona, a new species of Asteraceae from Hatay province of Turkey is described and illustrated. It is morphologically similar to C. cheirolopha (Fenzl) Wagenitz, C. lycopifolia Boiss. & Kotschy ex Boiss. & Kotschy, and C. stevenii Bieb. (Section Pseudoseridia), but it differs mainly in life form, general habit, leaves and achene characters. The IUCN conservation status of Critically Endangered (CR) should be applied to C. amanosensis.
