Australian thrips of the Haplothrips lineage (Insecta: Thysanoptera)

Keys are presented to the 11 genera and 50 species, including 21 new species, of Thysanoptera in Australia that are related to the worldwide genus Haplothrips Amyot and Serville. These taxa belong to what, in recent literature, has been called the “Haplothrips‐lineage”, that is, one of the three major radiations among the 2700 species and 350 genera of Thysanoptera Phlaeothripinae. The group is redefined, and the available tribal name Haplothripini shown to be appropriate. The character states on which the definition is based are discussed, and a list given of the 34 genera worldwide that can be included. The Australian species in these genera exhibit a diversity of biologies. Three genera involve species that invade galls induced by other thrips: Androthrips monsterae (Moulton) from New Guinea is newly recorded from Australia; Mesothrips jordani Zimmermann from South‐East Asia is newly recorded from Australia, with two new synonyms; the Asia‐Pacific genus, Euoplothrips Hood, includes two species in northern Australia. Three haplothripine genera are associated with grasses: one widespread genus, Apterygothrips Priesner, considered polyphyletic, includes only one Australian species; the only known species of Dyothrips Kudo is Oriental but extends into tropical Australia; Podothrips Hood, a circum‐tropical genus of thrips predatory on grass‐living coccoids, has 11 Australian species, six newly described. One grass‐associated genus, Bamboosiella Ananthakrishnan, is excluded from the Haplothripini. An Oriental genus of leaf‐ and flower‐living species, Dolichothrips Karny, includes one species in northern Australia, D. reuteri (Karny); Membrothrips Bhatti in which this species has been placed is considered a synonym. Karnyothrips Watson includes two species introduced to Australia, both predators of coccoids. Priesneria Bagnall includes three species from Australia, of which one fungus‐feeding species is newly described. Xylaplothrips Priesner is a widespread but ill‐defined, polyphyletic genus that currently includes three little‐known Australian species. Haplothrips is the main focus of this study, and character state variation among the Australian species is discussed. In total 24 species of Haplothrips from Australia are recognised, 14 being new species. Also included are the following, one new generic synonym, four new species synonyms, and one new combination. The 250 species worldwide in the genus are usually associated with the flowers of Asteraceae and Poaceae. In Australia, several of the species are specific to flowers, particularly of Poaceae and Cyperaceae but not Asteraceae. Almost half of these Australian species are presumed to be predatory on other small arthropods, and two have unusual host associations—with salt marsh Chenopodiaceae, and with the sori of Dicksonia tree ferns.     

Description of four new species of Hersiliidae (Arachnida,Araneae) from Kinabalu National Park,Sabah, Borneo,Malaysia

The family Hersiliidae includes, to date, seven genera and 148 species, distributed throughout tropical, subtropical and warm temperate zones. Of these, five genera and 30 species have been recorded from the Oriental region. In this paper, three new species of the genus Hersilia Audouin and one new species of the genus Tamopsis Baehr and Baehr are described from Kinabalu National Park, Sabah, Borneo, Malaysia.     

Synopsis of ‘onychocellid’ cheilostome bryozoan genera

Genera assigned to the cheilostome bryozoan family Onychocellidae are revised based on the skeletal morphology of the type species and, when possible, the type material of these species. All genera are illustrated using scanning electron micrographs, some for the first time. Onychocellidae, which ranges from the Cenomanian stage of the Cretaceous to the Recent, has been a particularly troublesome family because of poorly defined generic concepts correlating at least in part with a paucity of morphological characters. Thirty-five genera are described in this review. Of these, two are recognised as subjective synonyms of other onychocellid genera (Rhebasia and Semieschara), one cannot be sufficiently characterised from the type material (Collura), and two are new: Aechmellina gen. nov. (type species Aechmella falcifera) and Kamilocella gen. nov. (type species Eschara latilabris). A neotype is chosen for Rhagasostoma hexagonum, the type species of Rhagasostoma. A key is provided to assist in the identification of onychocellid genera. Phylogenetic relationships between genera remain obscure and are unlikely to be fully resolved based on skeletal morphology alone. The family as an entity is loosely circumscribed and almost certainly paraphyletic, containing stem genera of other anascan familes such as Lunulitidae, Coscinopleuridae and Aspidostomatidae.

Systematics and biology of the Rhinocolinae (Homoptera: Psylloidea)

Based on a cladistic analysis, the subfamily Rhinocolinae is redefined to comprise 13 genera and 39 species, of which two genera and eight species remain unnamed. Four new genera and 14 new species are described; one subfamily and one genus are synonymized, and two species are recombined; one lectotype is designated. The subfamily is divided into two groups, one with a Gondwanan distribution comprising four genera in Australia, New Zealand, South America and Africa, and another with Laurasian distribution in the Palaeotropics, the Western Palaerctic and North America comprising nine genera. Twenty-one species develop on host plants in the Rutales, three on Asteraceae, three on Cistaceae and one on Zygophyllaceae. The genus Pistacia (Anacardiaceae) in particular hosts six species whose biology is discussed.     

Recent and fossil Lunulitidae (Bryozoa: Cheilostomata) 4. American and Australian species of Otionella

The nominal, free living lunulitiform genus Otionella has been found to include two major groups of species, each one with a distinctive periancestrular pattern of primary zooids. The first group occurs in the Eocene of North America and includes the type species, O. perforata, and several other forms. The second group occurs in the Late Eocene to Recent of Australasia, and may prove to be generically distinct. Intermediate forms, such as O. parvula from the Argentinian Tertiary, are discussed, and a diverse fauna of 10 species from Australia is described. Although some of these species, like O. cupola, O. exigua and O. nitida, have long been known from Australia. it has only recently been recognized that three New Zealand forms, O. squamosa, O. zelandica and O. proberti, also occur in the Tertiary and/or Recent of Victoria, New South Wales, and Western Australia. In addition, four species are considered to be new. These include O. australis, O. auricula and O. minuta, which are probably closely related to one another, and to O. zelandica. The fourth species, O. browni, has a unique periancestrular budding pattern which resembles that of fossil Lunulites more than any form of ‘Australasian Otionella’. Although, in many ways, O. browni could be assigned to Lunulites sensu lato, it is included here in Otionella.     

The persistence of an ancient marine fauna in Mediterranean waters: new evidence from misophrioid copepods living in anchihaline caves

Two new species of misophrioid copepods are described from anchihaline cave habitats. Both sexes of Speleophriopsis canariensis are described from material collected on Lanzarote, Canary Is. Expansophria sarda is described from a single male collected on Sardinia. Both genera have widely disjunct distributions which are broadly Tethyan in character. Species of both genera are stenotopic and appear to be restricted to hypogean habitats of near-marine salinities. The presence of species of both genera on Mediterranean islands is interpreted as evidence of the persistence of marine fauna throughout the Messinian Salinity Crisis.     

The alimentary canal and nervous system of Curculionoidea (Coleoptera): gross morphology and systematic significance

The alimentary canal and central nervous system are described and illustrated for 208 species of weevils (Curculionoidea, representing 140 genera and eight families, and the results are compared with the published data on related species.

The phylogenetic importance of the alimentary canal and central nervous system of adult Curculionoidea is discussed. The alimentary canal and nervous system of the genera Car, Cylas, Eurhynchus, and Antliarhinus are described and the systematic position of these genera discussed. It is concluded that, on the basis of internal characters, Car, previously considered to belong to the Attelabidae, is better placed in the Apionidae; Cylas, now placed in the Brentidae, may be allied to both Brentidae and Apionidae; and both Eurhynchus and Antliarhinus are primitive apionids.     

The Villa group of genera in Africa and Eurasia with a review of the genera comprising Thyridanthrax sensu Bezzi 1924 (Diptera: Bombyliidae)

Summary

Bombyliidae are particularly abundant in arid regions where the greatest diversity of genera and species is found. The Villa group of genera (Anthracinae, Exoprosopini) are especially well represented in the Saharo-Sindian desert region. Difficulty in segregating genera has resulted from reliance on single key characters. Using a suite of characters, including the spermathecae largely overlooked previously, a key is provided to the eleven known genera in the Old World. The genus Thyridanthrax sensu Bezzi (1924) is reviewed and five genera are recognized: Thyridanthrax Osten-Sacken, Exhyalanthrax Becker, Pachyanthrax François, Veribubo Evenhuis, and Caecanthrax gen. nov. Species are allocated to these genera and new species Pachyanthrax laconae, Veribubo gazella and V. saffra and Caecanthrax auratus are also described.     

First record of the hyperparasite Liriopsis pygmaea (Cryptoniscidae,Isopoda) from a rhizocephalan parasite of the false king crab Paralomis granulosa from the Beagle Channel (Argentina), with a redescription

The Cryptoniscidae are epicaridean isopod parasites or hyperparasites of other crustaceans. Liriopsis Schultze in Müller, , one of the genera included in this family, now contains two nominal species: L. pygmaea (Rathke, ) and L. monophthalma (Fraisse, ). Both of these species infest rhizocephalan cirripeds, which are in turn parasites of hermit crabs. Among the false king crabs, Paralomis granulosa (Jacquinot, 1847), captured commercially in the Beagle Channel in 1996–1998, we found 31 specimens of the rhizocephalan Briarosaccus callosus Boschma, 1930 infested by one or more specimens of L. pygmaea. Neither L. pygmaea nor L. monophthalma has been reported previously for the southern seas. Although unidentified isopod hyperparasites have been found on B. callosus infesting other lithodids from Crozet Islands, South Georgia Island and Canadian Atlantic waters, this is the first time that one of these hyperparasites has been identified as a member of the genus Liriopsis. Since the differences between L. pygmaea and L. monophthalma remain obscure, the epicaridium and cryptoniscus larvae and three females stages of L. pygmaea are herein described from the material collected in the Beagle Channel.     

The complete larval development of Sadayoshia edwardsii (37) (Decapoda: Anomura: Galatheidae) described from laboratory‐reared material

The complete larval development of Sadayoshia edwardsii (Miers, ) is described and illustrated from laboratory‐reared material. The development comprises four zoeal and one megalopal stages. Diagnostic zoeal characters of Sadayoshia are provided and these are compared with other galatheid genera for which the larval morphology is known. Zoeas of S. edwardsii are readily distinguished from those of other galatheid species by the setation of the maxillular endopod together with the basis and endopod of the first maxilliped. The megalop of S. edwardsii has a flattened, triangular‐shaped rostrum, which differs remarkably from that of the adult. Although the rostral shape resembles that of Galathea megalops, the armature of the lateral margins is different between megalops of the two genera. The present larval study suggests that Sadayoshia is more closely allied to Galathea than to Munida.     

Three new genera of Banchinae (Hymenoptera: Ichneumonidae) from Central and South America

Three new genera and four new species of Banchinae are described from Central and South America: Terrylee gen. n., is described from Peru and Honduras to accommodate Terrylee olearius sp. n. and Terrylee peruensis sp. n. (type species: Terrylee peruensis sp. n.); Valdiviglypta gen. n. and Pristiboea gen. n. are described from Chile (type species: Valdiviglypta nimbus sp. n. and Pristiboea leiomano sp. n.). Terrylee and Pristiboea are placed in the tribe Atrophini, Valdiviglypta tentatively in the tribe Glyptini. All the three new genera are morphologically very distinctive and two have such character suites that they may not immediately be recognizable as banchines. By describing these three Neotropical genera from Chile, Honduras and Peru we aim to draw further attention to the considerable morphological variation within the ichneumonid subfamily Banchinae.     

Systematics and zoogeography of the deep‐sea hyperbenthic family Arietellidae (Copepoda: Calanoida) collected from the Sulu Sea

A faunistic survey of the deep‐sea hyperbenthic copepods in the Sulu Sea, which has a deep basin and is connected via shallow straits with the Pacific and the South China Sea, was carried out in November and December 2002, using beam trawls and a mid‐water trawl. Two new genera and four new species of the primitive calanoid family Arietellidae are described. A new genus Metacalanalis shows intermediate characteristics between those of Metacalanus Cleve, 1901 and Pilarella Alvarez, . Another new genus, Protoparamisophria, is closely related to Paramisophria Scott, 1897, but exhibits more plesiomorphic states in the female genital system and appendages. Two new species of the genera Paraugaptiloides Ohtsuka, Boxshall and Roe, and Sarsarietellus Campaner, 1984 are the second and the third species, respectively, for these genera. This discovery enhances the validity of these rare genera, and sheds light on the geological history of the Sulu Sea and the evolution of the Arietellidae within it.     

Two new genera of Bryozoa (Calloporidae) from New Zealand

Two new genera of the bryozoan family Calloporidae are described from New Zealand. The first, Leptinatella, is introduced for L. gordoni n. sp., specimens of which have been referred in the past to Watersia militaris (Waters) but are distinct from this species, which is a phase of the cribrimorph Corbulipora tubulifera (Hincks). The second genus, Bryocalyx, is introduced for B. cinnameus n. sp., which has small, conical colonies anchored by rhizoids. Another species of Bryocalyx is known from a few fragments only: and has also been referred in the past to Watersia sp. It is briefly discussed, but left unnamed here.     

A preliminary molecular phylogeny of the Sigalphinae (Hymenoptera: Braconidae), including Pselaphanus Szépligeti,based on 28S rDNA,with descriptions of new Afrotropical and Madagascan Minanga and Malasigalphus species

Minanga phoebea sp. n. Quicke, from Uganda, and Malasigalphus roa sp. n. Sharkey, from Madagascar, are described and illustrated. The new species of Minanga displays a distinct posterior metasomal carina and thus provides another example of the co‐occurrence of this feature with a metasomal carapace within the Braconidae. Malasigalphus roa is the second species of the genus recently described by Achterberg and Austin. A preliminary molecular phylogeny of the Sigalphinae is presented including the rare Neotropical genus Pselaphanus the placement of which has been debated. Sensitivity analysis to multiple alignment parameters was conducted and a single elided data set, based on the combined 21 separate alignments, was analysed. Strong support was obtained for the following relationships: Pselaphanus+(Malasigalphus+(other Sigalphinae)), (Minanga+(Sigalphus bicolor+(S. irrorator+S. gyrodontus))), and Earinini being basal (as a grade in these analyses) to other Agathidinae. The Mesocoelus group of genera (Mesocoelini in part) are shown to be derived agathidines rather than being associated with the Orgilini. The Microtypinae is shown be non‐monophyletic and Plesiotypus Achterberg is proposed as the sister group to the Agathidinae+Sigalphinae clade. The Acampsohelconinae does not appear as monophyletic; however, the placements of both of the two included genera, Afrocampsis and Canalicephalis, had less than 100% support in the elised analysis tree, and therefore monophyly of this recently redefined subfamily must be more rigorously tested.     

A new genus and species of Conchaspididae (Hemiptera: Coccoidea) from Florida,remarkable in lacking legs

A new genus of Conchaspididae, Asceloconchaspis gen. nov., is described for Asceloconchaspis milleri sp. nov., a new species from Florida, USA. Unlike other conchaspidids, the adult female and second instar of the genus lack legs. The presence of legs is one of the important, distinguishing characters at present separating the Conchaspididae from the Diaspididae. However, the new genus also possesses well-developed antennae and has multilocular disc pores on the abdomen in the adult female; these distinctly conchaspidid characters are never found in the Diaspididae. Asceloconchaspis is closely related to Fagisuga Lindinger, a monotypic genus with primitive characters described from South America on Nothofagus. A key to the four known genera of Conchaspididae is provided, and the morphology and distribution of the Conchaspididae are discussed.
