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.     

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 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.     

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.     

A new species of the genus Laboulbenia (Laboulbeniales) on Ophionea indica (Coleoptera, Carabidae, Odacanthini) from Taiwan

Laboulbenia ophioneae is described as a new species with illustrations. It is closely related to Laboulbenia celestialis and Laboulbenia asiatica because of some similarities in the morphology of appendages and perithecia. The present species from the latter two species can be distinguished by the shorter, inflated perithecia, the shorter receptacles, and the appendages consisting of more or less darkly colored, broader branches. This new species was found on elytra of Ophionea indica from Taiwan, which has been also known as a host of Laboulbenia polymorpha. A mature thallus noticed by Terada (2004) on the slide 673b (M. Ishikawa collection) and a young thallus illustrated by Sugiyama (1978, fig. 1-G as L. polymorpha) on 673d (M. Ishikawa collection) are both identified as L. ophioneae.     

Description of Nicrophorus efferens,new species,from Bougainville Island (Coleoptera,Silphidae, Nicrophorinae)

A new species of Nicrophorus in the nepalensis species-group, Nicrophorus efferens Sikes and Mousseau, is described from Bougainville Island in the Solomon Islands archipelago. It is distinguished from the known species of the genus Nicrophorus and its likely closest relative, Nicrophorus reticulatus Sikes and Madge, based on external morphology. A comparison among the four Nicrophorus species known from the Solomon Island archipelago and Papua New Guinea is presented.     

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 species of Bembidion ( Ecuadion) from Ecuador (Coleoptera,Carabidae, Bembidiini), with a key to members of the georgeballi species group

A new species of ground beetle, Bembidion ricei, is described from the Andes mountains of Ecuador east of Quito. It belongs to the georgeballi species group of subgenus Ecuadion, and is most similar to Bembidion georgeballi. A key to the species of the group is provided.     

Contributions to the Cladocera fauna from Papua New Guinea

Twenty-eight taxa of the Cladocera are identified in collections from Papua New Guinea, 17 being new records for New Guinea, bringing the total number of Cladocera taxa reported for this region to 39. Most of the taxa are circumtropical. One species (Sarsilatona papuana) is endemic to Papua New Guinea and northern Australia. The species list includes two species that are normally listed as Holarctic:Alonella nana andAlona rustica. Widespread genera such asDaphnia, Pleuroxus, Disparalona, Acroperus were strikingly absent from the Papua New Guinean material.     

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.     

Argentina adulterina (Rosaceae‐Potentilleae), a new species from New Guinea

Argentina adulterina Soják sp. nova from New Guinea (Irian Jaya) is described and compared with allied species. Habitually it is similar to A. irianensis, but in leaflet dentation it agrees with A. biloba. Leaves and leaflets of these three species are illustrated and a depiction of calyces of A. adulterina and A. irianensis is presented (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)     

Description of ten new Lobophora species from the Bismarck Sea (Papua New Guinea)

Sampling in the framework of the research program called ‘La Planète Revisitée’ in Kavieng and Madang (Papua New Guinea) brought thus far unknown diversity of the brown algal genus Lobophora to the surface. DNA‐assisted alpha taxonomy allowed identifying the presence of 16 species Lobophora from these two localities, which only share four species in common. Ten species are newly described, including four, which are only known to the Bismarck Sea. A more exhaustive sampling across the Bismarck Sea, and more largely across the Coral Triangle, will very likely unveil an even greater diversity. The present study underscores the fragmentary nature of our knowledge of macroalgal diversity in this region.     

On five species of the tribes Abacetini and Pterostichini (Coleoptera,Carabidae)

Metabacetus willi sp. n. (type locality: Indonesia, Central Java Province, Purworejo Regency, Kaligesing District, cave Seplawan near Donorejo) and Rhytiferonia beroni sp. n. (type locality: Papua New Guinea, West Sepik Province, Bonforok bil, Tifalmin, 1600 m) are described. Two new combinations: Poecilus (Ancholeus) campania (Andrewes, 1937), comb. n. of Feronia campania Andrewes, 1937, Aristochroa poecilma (Andrewes, 1937), comb. n. of Feronia poecilma Andrewes, 1937, and a new synonymy: Pterostichus (Oreophilus) podgoricensis B. Guéorguiev, 2013, syn. n. of Pterostichus (Oreophilus) flavofemoratus pinguis (Dejean, 1828), are proposed, too.     

A synopsis of the New Zealand Anillini (Coleoptera: Carabidae: Bembidiinae), with descriptions of new genera and species

Abstract

Pelodiaetodes n.gen. (type-species P. prominens n.sp.) and Hygranillus n.gen. (type-species H. kuscheli n.sp.) are described, and the following new synonymies are established: Nesamblyops oreobius (Broun, 1893) = N. coriaceus (Broun, 1908); Zeanillus pallidus (Broun, 1884) = Z. marginatus (Broun, 1914). Nine species of New Zealand Anillini are now recognised; they are distributed between five genera.

Exocelina baliem sp. n., the only known pond species of New Guinea Exocelina Broun, 1886 (Coleoptera,Dytiscidae, Copelatinae)

Exocelina baliem sp. n. is described from the Baliem Valley in the Central Mountain Range of New Guinea (Papua Province, Indonesia). Having striolate elytra, different structure and setation of the male and female genitalia and tarsomeres, and inhabiting swampy ponds, the new species differs from all known New Guinea species, which have smooth elytra and are stream associated. It forms a monophyletic group with the Australian Exocelina ferruginea (Sharp, 1882) and New Caledonian Exocelina inexspectata Wewalka, Balke & Hendrich, 2010, based on shape of the paramere and structure of the male tarsi. Habitus, protarsomeres, and male and female genitalia are illustrated, comparing some structures with Exocelina ferruginea and two New Guinea stream species. We briefly discuss the biogeographic relevance of this discovery.     

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.     

Calleida desenderi, new species from Ecuador (Coleoptera, Carabidae, Lebiinae)

Calleida desenderi Casale, sp. n., is described from Ecuador, Napo Province, surroundings of San Rafael. The new taxon is mostly characterized by the head and appendages rufous, the disc of elytra with marked metallic green reflection, the median lobe of aedeagus ring-like, and the endophallus with a long, twisted flagellum. A key for identification of the closer Neotropical species described so far is also provided.
