A revision of the genus Metallolophia Warren (Lepidoptera,Geometridae, Geometrinae)

The Geometrine genus Metallolophia is revised. In addition to the 11 species known, five new species are described as new. All the known species are redescribed and lectotypes are designated for M. opalina (Warren), M. arenaria (Leech) and M. danielaria (Oberthür) (=M. arenaria (Leech)). The male of M. ocellata (Warren) and the females of M. medullosa Inoue and M. devecisi Herbulot are described for the first time. The generic characters based on all species are summarized and a key to all taxa is given. Illustrations of moths and genitalia are presented. The new and revised taxa are: Metallolophia purpurivenata sp. nov., Metallolophia cuneataria sp. nov., Metallolophia inanularia sp. nov., Metallolophia flavomaculata sp. nov., Metallolophia stueningi sp. nov. and Metallolophia ostrumaria Xue, syn. nov. (of Metallolophia albescens Inoue).     

Five new species of Monocelis Ehrenberg, 1831 (Platyhelminthes: Proseriata) from eastern Australia

Six species of the genus Monocelis Ehrenberg, 1831 have been found in eastern Australia. All are new to science. Five of them are formally described here. Three species (M. rupisrubrae sp. nov., M. nexilis sp. nov., and M. corallicola sp. nov.) have two clearly set pigmented eyespots lateral to the statocyst. They differ in details of the copulatory organ and karyotype. No clear synapomorphies among them or with other species of the genus could be detected. Monocelis beata sp. nov. and M. macrobulbus sp. nov. present extremely elongate, longitudinally oriented copulatory organs. They are sister species, and phylogenetic relationships with M. galapagoensis Ax and Ax, 1977 and M. hopkinsi Karling, 1966 are proposed. Australian Monocelis have distributions limited to recognized biogeographical provinces in eastern Australia: M. corallicola, M. beata and M. macrobulbus in the northern Australian Zone, M. rupisrubrae and M. nexilis in the ‘Overlap Zone’ of the central east coast and Monocelis sp. A in the southern Australian Region.     

Four new species of Platycephala with a key to the Chinese species (Diptera,Chloropidae)

The following four new species of the genus Platycephala from China are described: Platycephala apicinigra sp. nov., P. brevifemura sp. nov., P. lateralis sp. nov. and P. nanlingensis sp. nov. An updated key to the species of the genus Platycephala from China is presented.

Two species are excluded from Euurobracon for the first time: E. nitidulus Brues, 1922 and E. mandibularis Brues, 1924. Each species of Euurobracon is fully described.     

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.     

A new genus and species of terrestrial isopod from Malaysia (Crustacea,Oniscidea, Platyarthridae)

A new terrestrial isopod, Cephaloniscus sociabilis gen. nov., sp. nov., from Fraser Hill in central Malaysia, is described and illustrated. The new genus belongs to the family Platyarthridae and is distinguished from other members of the family by the characteristic structure of the cephalon. The specimens were collected from the nest of the termite Hospitalitermes sp. (near medioflavus Holmgren) together with the ant Centromyrmex hamulatus (Karavaiev).     

An account of the mealybug genus Paraputo Laing (Hemiptera: Coccoidea: Pseudococcidae) in the Pacific region

The mealybug genus Paraputo is discussed from the Pacific region and three new species, P. aracearum sp. nov., P. chimbuensis sp. nov., and P. guadalcanalae sp. nov., are described and illustrated. They are discussed with two species, P. kukumi Williams and P. leveri (Green), already known from the area. Most of the species are found on economic plants and one of the mealybugs, P. leveri, has been recorded as possibly invasive. A key to adult females is provided.     

A synopsis of Martarega White, 1879 (Insecta: Heteroptera: Notonectidae) occurring in the Brazilian Amazonia,with descriptions of three new species

The genus Martarega comprises 15 species and nine of these have been recorded in northern Brazil. Martarega pydanieli sp. nov. from Rondônia, while Martarega nieseri sp. nov. and M. barcelos sp. nov. from Amazonas are described here. Six known species are recorded in the Brazilian Amazonian Region (Amazonas, Pará, Rondônia and Roraima): M. brasiliensis, M. chinai, M. gonostyla, M. membranacea, M. oriximinaensis, and M. uruguayensis. At the outset of this survey the genus Martarega of the Brazilian Amazonian Region held 12 species, but no specimens of M. mcateei, M. hungerfordi, and M. williamsi were collected in the regions sampled. Martarega brasiliensis is newly recorded from Roraima, which comprises the first record of members of this genus in this State. Martarega uruguayensis is newly recorded from Pará and Rondônia, while M. gonostyla from Rondônia. Distinct keys to males and females of Martarega occurring in this region, including these new species, are provided.     

The genus Thoradonta in Thailand (Orthoptera: Tetrigidae: Scelimeninae) with description of two new species

The genus Thoradonta Hancock (Orthoptera: Tetrigidae: Scelimeninae) is newly reported from Thailand. Two new species of the genus, Thoradonta lativertexoides sp. nov. and Thoradonta spiculobaoides sp. nov., are described and illustrated with photographs and compared with similar species. A taxonomic review of the genus Thoradonta is provided and a key to all known species of the genus is given.     

A new earthworm genus Nouraguesia gen. nov. from French Guiana with description of two new species (Oligochaeta,Glossoscolecidae)

Nouraguesia gen. nov., consisting of three species, is described from Eastern Amazonia. Species belonging to this genus are middle-sized earthworms inhabiting, based on our experience, decomposing tree logs and space filled with detritus between leaf-axils and trunk (e.g. in some palm species). The new genus is morphologically similar to the genus Andiorrhinus, but differs from it by the presence of numerous caeca encircling the intestine in segment 27. The three species belonging to the newly established genus are known from state Amapa in Brazil (N. amaparis (Righi, 1971)); and French Guiana (N. parare sp. nov., N. souadae sp. nov.).     

New Aoridae (Crustacea: Amphipoda) from Tasmanian kelp holdfasts

Three new aorid amphipod species from Tasmanian kelp holdfasts are described: Microdeutopus varietensis sp. nov., Lembos clematis sp. nov. and L. verrucularum sp. nov. Strong sub-ocular regression of the head is a usual feature of the genus Microdeutopus and is shown by M. varietensis. It is not, however, typical of the other known Australian/NewZealand Microdeutopus species (M. haswelli and M. apopo). The Tasmanian Lembos species (L. chiltoni, L. clematis and L. verrucularum) are not known from New Zealand, where the genus is represented by L. pertinax, L. acherontis and L. hippocrenes. The Tasmanian Lembos species display the condition of the mandibular palp that typifies the genus, that is, article 3 longer than article 2 (cf. the New Zealand species which display the reverse, unusual, condition).     

A synopsis of the subterranean mealybug genus Neochavesia Williams and Granara de Willink (Hemiptera: Pseudococcidae: Rhizoecinae)

The neotropical mealybug genus Neochavesia, associated with the ant genus Acropyga Roger, is discussed and placed in the tribe Xenococcini on the bases that it lacks dorsal ostioles, the distal end of the circulus is depressed and cup-shaped, and the third-instar female is a pupa. These are characters shared by Xenococcus Silvestri and Eumyrmococcus Silvestri, also in the tribe Xenococcini, and differ from those in the tribe Rhizoecini, the other tribe in the subfamily Rhizoecinae. Two new species, Neochavesia iwokramae sp. nov. and N. lapollai sp. nov., are described from Guyana, and the female pupal instar and adult male of N. lapollai and the adult male of N. caldasiae (Balachowsky) are described and illustrated. A key to adult females is provided.     

Scale insects of the families Asterolecaniidae and Eriococcidae (Hemiptera: Coccoidea) in New Caledonia

The scale insect families Asterolecaniidae and Eriococcidae are discussed from New Caledonia. One new genus Oacoccus gen. nov., and a new species Oacoccus nothofagi sp. nov. on Nothofagus sp., are described in the Asterolecaniidae, and a new species Eriococcus millei sp. nov. is described in the Eriococcidae. A new genus Rhopalotococcus gen. nov., and two new species Rhopalotococcus dugdalei sp. nov. and Rhopalotococcus metrosideri sp. nov., are also described in the Eriococcidae. Both species induce leaf galls on Metrosideros sp. Keys are provided for all the New Caledonian genera and species in the families Asterolecaniidae and Eriococcidae.
