Chinese species of the genus Prochiloneurus Silvestri with description of a new species(Hymenoptera: Encyrtidae)

Four species of the genus Prochiloneurus Silvestri, belonging to the family Encyrtidae of Hymenoptera, are reported from China. Among them, P. stenopterus sp. nov., which is reared as the hyperparasitoid of Phenacoccus solenopsis Tinsley(Hemiptera: Pseudococcidae), an invasive mealybug to China, is reported as new to science. A key of the genus is provided for the recognition of the females of Chinese species. Notes on the parasitoid and hyperparasitoid of the mealybug Phenacoccus solenopsis are provided.     

Two new egg parasitoids (Hymenoptera: Encyrtidae) of the wood borer Agrianome spinicollis (Macleay) (Coleoptera: Cerambycidae), a pest of pecans in eastern Australia

Abstract Baeoanusia xanthopleuron sp. n. and Avetianella coombsi sp. n. (Hymenoptera: Encyrtidae) are described from New South Wales and Queensland. Photomicrographs are provided to illustrate morphological characters of both species, and their systematic position is discussed on the basis of their morphology and biology. Both species are egg parasitoids of the wood borer Agrianome spinicollis (Macleay), an important pest of pecans in eastern Australia.     

Two new species of Acizzia Crawford (Hemiptera: Psyllidae) from the Solanaceae with a potential new economic pest of eggplant, Solanum melongena

Two new species of Acizzia Heslop-Harrison (Hemiptera: Psyllidae) from the plant family Solanaceae in eastern Australia are described. Acizzia solanicola sp. n. can damage eggplant, Solanum melongena (Solanaceae), in commercial crops and gardens in eastern Australia. It is a new, potentially serious commercial pest species, of which the nymphs induce malformation of leaves, produce copious amounts of viscous waste and cause leaf wilting, premature leaf senescence and crop loss. These psyllids have a unique and characteristic method of disposing of honeydew and this is illustrated for the first time. Acizzia alternata sp. n. is recorded from the weed, wild tobacco bush, Solanum mauritianum , but appears to cause little damage. These comprise the first record of a pest psyllid on eggplant and the first record of Acizzia from the Solanaceae. The parasitoid, Psyllaephagus sp. (Hymenoptera: Encyrtidae), is recorded parasitising nymphs of A. solanicola sp. n., and is here proposed as a potential biological control agent against it.     

The biology of Psyllaephagus bliteus Riek (Hymenoptera: Encyrtidae), a parasitoid of the red gum lerp psyllid (Hemiptera: Psylloidea)

The red gum lerp psyllid, Glycaspis brimblecombei Moore (Hemiptera: Psylloidea), is native to Australia, where it feeds upon Eucalyptus species. It first appeared near Los Angeles, California, in 1998, and soon spread throughout the state. A biological control program directed against the psyllid was initiated and Psyllaephagus bliteus Riek (Hymenoptera: Encyrtidae) was imported from Australia and released in California. During quarantine screening, the taxonomic status of Psyllaephagus quadricyclus Riek was assessed by one of us (RLZ) and is proposed here as a new junior synonym for P. bliteus. The experiments discussed herein provide basic biological information on P. bliteus to supplement and improve the control program. We found that P. bliteus can oviposit into psyllid nymphs of any age but prefers third and fourth instars. Observations of host-handling behavior suggest that the large lerps of fifth instar psyllids increase host-handling time, thereby impeding oviposition and providing some protection from parasitism. Female P. bliteus were observed host-feeding on all psyllid nymphal development stages. Adults are relatively long-lived and, at constant temperatures of 17, 21, 23, 26, and 32 °C, longevity is a negative linear function of temperature. Females lived significantly longer than males. Adult females can live for several months, provided with hosts and held under glasshouse conditions (22 ± 3 °C), however, maximum egg deposition occurred within 22 days after adult emergence. Studies of larval development show that P. bliteus is a koinobiont and larval development is not initiated until the host reaches the late fourth or early fifth instar.     

Pseudofoenus caledonicus, a new species of hyptiogastrine wasp (Hymenoptera: Gasteruptiidae) from New Caledonia

Abstract  Pseudofoenus caledonicus sp. nov. is described from New Caledonia, and is the second member of the Hyptiogastrinae recorded from these islands. This discovery points to a more diverse fauna of Hyptiogastrinae in the south-west Pacific, which also includes P. ritae (Cheesman), from New Caledonia and Vanuatu, P. extraneus (Turner) from Fiji, and a number of species from New Guinea and New Zealand. Although a revised phylogenetic analysis does not resolve the relationships of P. caledonicus , neither the two New Caledonian species nor the south-west Pacific fauna in general are likely to be monophyletic. This fauna is discussed in terms of its relationships with Pseudofoenus spp. from mainland Australia, and possible mechanisms that have given rise to the current distribution of species.     

The Australian endemic woodwasp genus Austrocyrta Riek (Hymenoptera: Xiphydriidae)

The Australian xiphydriid woodwasp genus Austrocyrta , previously known only from a single species, A. australiensis Riek, is revised. A second distinctive species from Carnarvon National Park in south-central Queensland, A. fasciculata Jennings & Austin, sp. nov., is described, and a key to separate the males of the two species is provided.     

Cardinium in Plagiomerus diaspidis (Hymenoptera: Encyrtidae)

The bacterial symbiont Cardinium (Bacteroidetes) was previously implicated in the thelytokous reproduction of the parasitoid Plagiomerus diaspidis Crawford (Hymenoptera: Encyrtidae). Horizontal transmission of the symbiont among the cactus scale Diaspis echinocacti Bouché (Homoptera: Diaspididae) and its hymenopteran parasitoids has been suggested. In this study, the bacteria associated with D. echinocacti, its parasitoids P. diaspidis and Aphytis sp. (Hymenoptera: Aphelinidae), and the hyperparasitoid Marietta leopardina Motschulsky (Hymenoptera: Aphelinidae) were characterized using molecular fingerprinting techniques, and the localization of Cardinium in P. diaspidis was studied using fluorescence in situ hybridizations (FISH). Cardinium was the only bacterium found in P. diaspidis, but it could not be detected in any of the other insects tested. The symbiont was specifically located in the reproductive tissues of its P. diaspidis host.

Systematics of the bryozoan genus Macropora (Cheilostomata)

Macropora is a distinctive genus of anascan cheilostomes. All species have large zooids with an extensive cryptocystal frontal shield perforated by numerous pores through which parietal muscle strands pass. Also characteristic of Macropora are the calcified opercula closing the d -shaped orifice, avicularia resembling autozooids but having slightly enlarged, typically crenulated opercula/mandibles, and large ovicells that are often costate. This mostly Australasian genus has a documented fossil record stretching back to the Eocene. Here we revise the generic diagnosis of Macropora and describe eight new species from New Zealand (three Recent: M. nodulosa sp. nov. , M. filifera sp. nov. and M. carlosi sp. nov. ; five fossil: M. septispinosa sp. nov. , M. similis sp. nov. , M. pittensis sp. nov. , M. leeae sp. nov. and M. bullata sp. nov. ) and one new species from Japan ( M. mawatariorum sp. nov. ), the only species known with certainty to occur in the northern hemisphere. New observations are given for some previously described species, several of which are illustrated using SEM for the first time. The northern hemisphere Upper Cretaceous species Monoporella exsculpta (Marsson), showing features allowing it to be placed tentatively in the stem-group of Macropora , is redescribed. Attempts to resolve the phylogenetic relationships of species within Macropora were hampered by the relatively few morphological characters compared with the number of species, and it proved impossible to obtain a phylogeny robust to slight changes in taxon and/or character inclusion. The favoured cladogram has poor bootstrap and Bremer support, and its stratigraphical and biogeographical congruences are low.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 153 , 115–146.     

NEW RECORDS OF TWO GENERA OF TETRACNEMINAE (HYMENOPTERA: ENCYRTIDAE) WITH TWO NEW SPECIES IN CHINA

Abstract  Two new species of Tetracneminae, Encyrtidae, collected from Heilongjiang, Liaoning, and Yunnan, China are described, i.e. Dusmetia latiscapa Xu, sp. nov, and Gyranusoidea yunnanensis Xu, sp. nov. Dusmetia latiscapa Xu, sp. nov differs from Dusmetia cardinalis Hoffer, 1969 in the coloration of the apical forth funicular segment and the fifth-sixth funicular segments of antennae; (2) length of scape; (3) having undeveloped fore wing and (4) the coloration of body. Gyranusoidea yunnanensis Xu, sp. nov. can be distinguished from the Gyranusoidea hecale Noyes et Hayat 1988 by (1) 1 brown match between antennal scrobe and orbit; (2) scape 5.0 times as long as wide, and (3) antennal scape without white ring subapically. Both two genara of Dusmetia Mercet, and Gyranusoidea Compere are recorded for the first time in China. All specimens examined are deposited in Institute of Applied Entomology, Agriculture & Biotechnology College, Zhejiang University, Hangzhou, China.
