缘蝽总科支序分析及其高级分类系统(半翅目:异翅亚目)(英)

本文在已有大量比较形态学研究和各科支序分析研究基础上,对缘蝽总科的科、亚科、族等亚群的系统发育关系作了支序分析研究,结果表明,缘蝽总科、蛛缘蝽科、姬缘蝽科的单系群地位得到证明。而缘蝽科由于其棒缘蝽亚科和希缘蝽亚科分别占据支序图的两个最低位置,它们在缘蝽总科中具有较多的原始特征,缘蝽亚科的Chariesterini族与南美缘蝽亚科互为姐妹群而与缘蝽亚科其它族差异较大;姬缘蝽科的红缘蝽亚科处在该分支的最高位置且与姬缘蝽亚科中的Harmostini族互为姐妹群,与姬缘蝽亚科其它族关系也较近,因而传统的缘蝽科、缘蝽亚科、姬缘蝽亚科为并系群。为使各分类单元为单系群即自然类群,使分类系统更忠实于系统发育关系,本文将棒缘蝽亚科和希缘蝽亚科分别提升为科,Chariesterini族提升为亚科;红缘蝽亚科降为族,姬缘蝽科不设亚科。据上述分类学变动提出了缘蝽总科族以上高级阶分类系统。     

缘蝽科族级单元系统发育关系支序分析(半翅目:异翅亚目:缘蝽总科)

在已有比较形态学研究基础上,本文选择了15个特征方面（外生殖器为主）的74个新征,以支序分析方法探讨了缘蝽科族（或亚科）的系统发育关系。结果表明棒缘蝽亚科、希缘蝽族、沟缘蝽族较为原始,与其余类群差异较大,缘蝽科的范围值得进一步研究;除Chariesterini外的缘蝽亚科是高等的缘蝽类群;Chariesterini似应从缘蝽亚科中独立出来;狭义巨缘蝽族以及萧的鼻缘蝽族、梭缘蝽族、昧缘蝽族、曼缘蝽族成立;拟黛缘蝽属、副黛缘蝽属、华黛缘蝽属、异黛缘蝽属应从”黛缘蝽族”中分别独立出来成立新族,即拟黛缘蝽族、副黛缘蝽族、华黛缘蝽族和异黛缘蝽族,以使原有的黛缘蝽族成为自然类群。     

Phylogenomic analysis suggests Coreidae and Alydidae (Hemiptera: Heteroptera) are not monophyletic

Next‐generation sequencing technologies (NGS) allow systematists to amass a wealth of genomic data from non‐model species for phylogenetic resolution at various temporal scales. However, phylogenetic inference for many lineages dominated by non‐model species has not yet benefited from NGS, which can complement Sanger sequencing studies. One such lineage, whose phylogenetic relationships remain uncertain, is the diverse, agriculturally important and charismatic Coreoidea (Hemiptera: Heteroptera). Given the lack of consensus on higher‐level relationships and the importance of a robust phylogeny for evolutionary hypothesis testing, we use a large data set comprised of hundreds of ultraconserved element (UCE) loci to infer the phylogeny of Coreoidea (excluding Stenocephalidae and Hyocephalidae), with emphasis on the families Coreidae and Alydidae. We generated three data sets by including alignments that contained loci sampled for at least 50%, 60%, or 70% of the total taxa, and inferred phylogeny using maximum likelihood and summary coalescent methods. Twenty‐six external morphological features used in relatively comprehensive phylogenetic analyses of coreoids were also re‐evaluated within our molecular phylogenetic framework. We recovered 439–970 loci per species (16%–36% of loci targeted) and combined this with previously generated UCE data for 12 taxa. All data sets, regardless of analytical approach, yielded topologically similar and strongly supported trees, with the exception of outgroup relationships and the position of Hydarinae. We recovered a monophyletic Coreoidea, with Rhopalidae highly supported as the sister group to Alydidae + Coreidae. Neither Alydidae nor Coreidae were monophyletic; the coreid subfamilies Hydarinae and Pseudophloeinae were recovered as more closely related to Alydidae than to other coreid subfamilies. Coreinae were paraphyletic with respect to Meropachyinae. Most morphological traits were homoplastic with several clades defined by few, if any, synapomorphies. Our results demonstrate the utility of phylogenomic approaches in generating robust hypotheses for taxa with long‐standing phylogenetic problems and highlight that novel insights may come from such approaches.     

姬缘蝽科系统发育初探：（异翅亚目：缘蝽总科）

本文通过对姬缘蝽科１４属的比较形态学研究,以支序分析方法探讨了各类间的系统发育关系,３其结果证明姬缘蝽科为一明显单系群,并支持Ｃｈｏｐｒａ（１９６７）系统中大部分族的划分意见,但因支序图中玛缘蝽族和姬缘蝽亚科为并系群,从而对Ｃｈｏｐｒａ系统中亚科的划分及玛缘蝽族是否成立提出疑问,并认为已有系统中的“红缘蝽亚科”应降为族级。文中还将支序分析结果与经前作者的系统发育意见相比较,认为本文所提出的关于该科

First Record of the Tribe Hydarini in Australia with the Description of a New Species of Hydarella Bergroth (Hemiptera: Coreidae)

Hydarella weiri sp.n. is described from the Northern Territory and Western Australia. This is the first member of the tribe Hydarini (Coreidae: Coreinae) recorded from Australia. Its relationships are discussed, and a key to Hydarella spp. is included. the head, pronotum, pygophore and female external genitalia are figured.     

Phylogeny and classification of Marantaceae

Relationships of Marantaceae were estimated from nucleotide sequence variation in the rps16 intron (plastid DNA) and from morphological characters. Fifty-nine species (21 genera) formed the ingroup, and 12 species (12 genera) of other Zingiberales formed the outgroup. There is no support for the traditional subdivision of Marantaceae into a triovulate and a uniovulate tribe or the informal groups previously proposed. The so-called Donax group forms a paraphyletic grade that is basal within Marantaceae. Thalia appears as the distal branch of this grade, but its position is not supported in jackknife analysis. The so-called Calathea group is monophyletic in all shortest trees but not supported with greater than 50% jackknife. The genus Calathea appears to be paraphyletic. The Maranta and Phrynium groups are clearly polyphyletic. Maranta, Koernickanthe , and genera of the Mymsma group, all neotropical, form a strongly supported monophyletic group. The sister of this group is the palaeotropical genus Halopegia. Koernickanthe is nested within Maranta , as this genus is traditionally circumscribed. The African genera Ataenidia and Marantochloa form a strongly supported clade in which Ataenidia is the sister group to Marantochloa . Based on phylogeny it is concluded that Africa, in spite of being much poorer in species, is the most likely ancestral area of Marantaceae     

基于18S rDNA序列的蝽次目(半翅目：异翅亚目)

利用18SrDNA分子约1 912 bp的序列对蝽次目21个科53个种进行系统发育分析。运用MP法、ML法和NJ法分析后的结果表明:蝽次目的单系性得到很高的支持;扁蝽总科成为毛点类的姐妹群;毛点类基本确定为两大分支:一支包含蝽总科和红蝽总科;另一支主要由长蝽总科、缘蝽总科和南蝽总科组成;长蝽总科和缘蝽总科都是多系;长蝽总科中,跷蝽科和皮蝽科的关系最近,构成姐妹群,位于整个毛点类的基部;与长蝽总科中另外两个科长蝽科和地长蝽科的关系很远。说明利用18SrDNA分子对研究蝽次目的系统发育关系是适合的,能够重建蝽次目;扁蝽总科和蝽总科单系性的结果与形态学的研究以及Li et al (2005)的研究一致;但较Li et al(2005)的研究更进一步把红蝽总科从广义的缘蝽总科中分出来;并建议皮蝽科作为一个独立的总科更合适。     

Characteristics of sperm ultrastructure in the gall midges Porricondylinae (Insecta,Diptera, Cecidomyiidae), with phylogenetic considerations on the subfamily

 Sperm ultrastructure was studied in ten genera of the Porricondylinae (Cecidomyiidae). Sperm structure is remarkably simplified by the absence of the acrosome and the accessory tubules, as happens in all the cecidomyiid flies. All genera of the Porricondylinae show a peculiar 9+3 axonemal model except Diallactes, which retains the plesiomorphic condition of a 9+2 axoneme, and Winnertzia, which appears to have secondarily acquired a 9+0 model. A cladistic analysis of relevant sperm characters (based on the axonemal model, the number of mitochondrial derivatives and the size and structure of the centriolar adjunct) was performed to infer phylogenetic relationships among six tribes of the Porricondylinae. In this cladogram, the Porricondylini are the sister group to the Asynaptini, Heteropezini and Winnertzini and these four taxa form the sister group to the Dicerurini. The tribe Diallactini are regarded as the group with the most plesiomorphic characters within the family. Accepted: 15 March 1996     

Review of the systematics and phylogenetic relationships of the Sabethini (Diptera: Culicidae)

This paper reviews the historical treatment of the tribe Sabethini and genus-group taxa and examines the unusual life histories associated with the group. Although recognized by taxonomists as distinct, the taxonomic position of sabethines has been questioned and their rank within the family Culicidae unstable. In order to evaluate the current status of the classification of the tribe a cladistic analysis is performed. Thirty-seven taxa are selected from within the Sabethini and two outgroups were chosen from the tribe Aedini. Exemplars are selected from genus-group taxa world-wide and new and traditional character systems examined in larval, pupal and adult life stages. The results firmly establish the sabethines as a monophyletic group. However, the genera Runchomyia , Tripteroides and Wyeomyia are not demonstrably monophyletic. In addition, the data support the New World taxa as a monophyletic group to a paraphyletic assemblage of Old World taxa. The pattern displayed by the cladogram suggests the ability to vector arboviruses has arisen more than once in mosquitoes.     

A comprehensive molecular phylogeny of tiger beetles (Coleoptera,Carabidae, Cicindelinae)

Tiger beetles are a remarkable group that captivates amateur entomologists, taxonomists and evolutionary biologists alike. This diverse clade of beetles comprises about 2300 currently described species found across the globe. Despite the charisma and scientific interest of this lineage, remarkably few studies have examined its phylogenetic relationships with large taxon sampling. Prior phylogenetic studies have focused on relationships within cicindeline tribes or genera, and none of the studies have included sufficient taxon sampling to conclusively examine broad species patterns across the entire subfamily. Studies that have attempted to reconstruct higher‐level relationships of Cicindelinae have yielded conflicting results. Here, we present the first taxonomically comprehensive molecular phylogeny of Cicindelinae to date, with the goal of creating a framework for future studies focusing on this important insect lineage. We utilized all available published molecular data, generating a final concatenated dataset including 328 cicindeline species, with molecular data sampled from six protein‐coding gene fragments and three ribosomal gene fragments. Our maximum‐likelihood phylogenetic inferences recover Cicindelinae as sister to the wrinkled bark beetles of the subfamily Rhysodinae. This new phylogenetic hypothesis for Cicindelinae contradicts our current understanding of tiger beetle phylogenetic relationships, with several tribes, subtribes and genera being inferred as paraphyletic. Most notably, the tribe Manticorini is recovered nested within Platychilini including the genera Amblycheila Say, Omus Eschscholtz, Picnochile Motschulsky and Platychile Macleay. The tribe Megacephalini is recovered as paraphyletic due to the placement of the monophyletic subtribe Oxycheilina as sister to Cicindelini, whereas the monophyletic Megacephalina is inferred as sister to Oxycheilina, Cicindelini and Collyridini. The tribe Collyridini is paraphyletic with the subtribes Collyridina and Tricondylina in one clade, and Ctenostomina in a second one. The tribe Cicindelini is recovered as monophyletic although several genera are inferred as para‐ or polyphyletic. Our results provide a novel phylogenetic framework to revise the classification of tiger beetles and to encourage the generation of focused molecular datasets that will permit investigation of the evolutionary history of this lineage through space and time.     

Abundance and species richness of Coreoidea (Hemiptera: Heteroptera) from Parque Estadual do Turvo, Southern Brazil

The coreoid fauna from Neotropics is poorly known, especially in terms of community studies. Aiming at contributing to this knowledge, a two-year study was carried out at Parque Estadual do Turvo, Municipality of Derrubadas, state of Rio Grande do Sul, Brazil, to evaluate the composition, abundance and species richness of Coreoidea. Samplings were conducted in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using beating tray method, along two trails of the park. Sampling effort (hours X collectors) totaled 153h. A total of 282 individuals of Coreoidea were collected, distributed in 28 species of Alydidae, Coreidae and Rhopalidae. The most abundant species was the coreid Cebrenis supina Brailovsky, representing 16% of the collected individuals, followed by the rhopalids Jadera aeola (Dallas), and Harmostes sp., with 12.1% and 11.7%, respectively. The estimated richnesses by Chao 1, Chao 2, Jackknife 1 and Jackknife 2 indicated that the observed richness corresponds to 70% to 80% of the expected for the area. The estimated richness through rarefaction was significantly higher in spring 2003 and autumn 2004 than in the other periods. There was no significant difference, however, between spring of 2003 and autumn of 2004, and between spring of 2004 and autumn of 2005, for the same parameter. Yucum? and Garcia trails did not differ significantly for the estimated richness. Singletons and doubletons represented 32.1% of the recorded species. Additionally, eight other species were obtained qualitatively by using, besides beating tray without protocol, manual collection.     

Phylogenetic relationships in the bovid subfamily Antilopinae based on mitochondrial DNA sequences.

A molecular phylogeny of the subfamily Antilopinae was determined using the two mitochondrial DNA (mtDNA) genes cytochrome b and cytochrome c oxidase III. The tribe Antilopini is monophyletic with Antidorcas marsupialis and Litocranius walleri basal to the large genus Gazella. Antilope cervicapra falls within Gazella. This placement would either make Gazella paraphyletic or require that the genus name Gazella be changed to Antilope. Gazella thomsonii is supported as a subspecies of G. rufifrons. Most members of the tribe Neotragini are sister species to the Antilopini, but the Neotragini is rendered paraphyletic by a deep placement of Neotragus moschatus.     

A molecular phylogeny of fleas (Insecta: Siphonaptera): origins and host associations

Siphonaptera (fleas) is a highly specialized order of holometabolous insects comprising ～2500 species placed in 16 families. Despite a long history of extensive work on flea classification and biology, phylogenetic relationships among fleas are virtually unknown. We present the first formal analysis of flea relationships based on a molecular matrix of four loci (18S ribosomal DNA, 28S ribosomal DNA, Cytochrome Oxidase II, and Elongation Factor 1‐alpha) for 128 flea taxa from around the world representing 16 families, 25 subfamilies, 26 tribes, and 83 flea genera with eight outgroups. Trees were reconstructed using direct optimization and maximum likelihood techniques. Our analysis supports Tungidae as the most basal flea lineage, sister group to the remainder of the extant fleas. Pygiopsyllomorpha is monophyletic, as are the constituent families Lycopsyllidae, Pygiopsyllidae, and Stivaliidae, with a sister group relationship between the latter two families. Macropsyllidae is resolved as sister group to Coptopsyllidae with moderate nodal support. Stephanociricidae is monophyletic, as are the two constituent subfamilies Stephanocircinae and Craneopsyllinae. Vermipsyllidae is placed as sister group to Jordanopsylla. Rhopalopsyllidae is monophyletic as are the two constituent subfamilies Rhopalopsyllinae and Parapsyllinae. Hystrichopsyllidae is paraphyletic with Hystrichopsyllini placed as sister to some species of Anomiopsyllini and Ctenopariini placed as sister to Carterettini. Ctenophthalmidae is grossly paraphyletic with the family broken into seven lineages dispersed on the tree. Most notably, Anomiopsyllini is paraphyletic. Pulicidae and Chimaeropsyllidae are both monophyletic and these families are sister groups. Ceratophyllomorpha is monophyletic and includes Ischnopsyllidae, Ceratophyllidae, and Leptopsyllidae. Leptopsyllidae is paraphyletic as are its constituent subfamilies Amphipsyllinae and Leptopsyllinae and the tribes Amphipsyllini and Leptopsyllini. Ischnopsyllidae is monophyletic. Ceratophyllidae is monophyletic, with a monophyletic Dactypsyllinae nested within Ceratophyllinae, rendering the latter group paraphyletic. Mapping of general host associations on our topology reveals an early association with mammals with four independent shifts to birds. © The Willi Hennig Society 2008.     

Phylogenetic relationships, ecological correlates, and molecular evolution within the cavioidea (mammalia, rodentia)

A molecular phylogeny of the rodent superfamily Cavioidea was derived using two nuclear sequences (exon #10 of the growth hormone receptor gene and intron #1 of the transthyretin gene) and one mitochondrial gene (12S rRNA). A combined analysis produced a highly derived and well-supported phylogenetic hypothesis that differed from traditional taxonomy primarily in the placement of two taxa. Kerodon, traditionally included within the subfamily Caviinae with guinea pigs and its relatives, is placed sister to the family Hydrochaeridae and closely aligned with the subfamily Dolichotinae. Inclusion of Hydrochaeris within the Caviidae renders the familial classification paraphyletic. Our data further support the taxonomic separation of the families Agoutidae and Dasyproctidae. Both the molecular and traditional morphological interpretations are assessed in testing an ecological constraints hypothesis regarding social behaviors. Whereas traditional taxonomy is consistent with an environmental constraints explanation for social behavior, the molecular data suggest that phylogenetic effects may be a more important factor in the evolution of social behavior in this group. Although lineage-specific rate heterogeneity was identified in all three molecular data sets, no significant support was obtained for the metabolic rate hypothesis. However, both nuclear genes displayed patterns in accordance with the generation time hypothesis.     

Molecular Phylogeny of Rhizophoraceae Based on rbcL Gene Sequences

rbcL sequences to clarify the inter- and intrarelationships of Rhizophoraceae which have been variously discussed. The analyses included 12 of the 15 genera of Rhizophoraceae (4/7 of Macarisieae, 4/4 of Gynotrocheae, and 4/4 of Rhizophoreae) and a few putatively related taxa, including two of the four genera of Anisophylleaceae. The most parsimonious trees supported the monophyly of Rhizophoraceae as well as each of the three traditionally recognized tribes Macarisieae, Gynotrocheae, and Rhizophoreae. The family Rhizophoraceae is a sister taxon to Erythroxylum (Erythroxylaceae) and is further closely related to Byrsonima (Malpighiaceae), Passiflora (Passifloraceae), Turnera (Turneraceae), Ochna (Ochnaceae), Drypetes (Euphorbiaceae), and Humiria (Humiriaceae). Anisophylleaceae, which have often been included in Rhizophoraceae as a tribe or subfamily, are placed in a common clade with Begonia (Begoniaceae), Cucurbita (Cucurbitaceae), Coriaria (Coriariaceae), Corynocarpus (Corynocarpaceae), Datisca (Datiscaceae), Tetrameles (Datiscaceae), and Octomeles (Datiscaceae). Within Rhizophoraceae the mangrove tribe Rhizophoreae is sister to the inland tribe Gynotrocheae, with inland tribe Macarisieae positioned as a sister taxon to these two tribes. This pattern of relationships within the family basically agrees with those suggested by cladistic analyses based on morphological characters, except that Gynotrocheae are monophyletic with Crossostylis as a derived taxon within the tribe in the present study. Based on this cladogram for Rhizophoraceae, we discuss evolutionary trends of a few ecological and morphological characters, including the formation of aerial roots and the ovary position.

Evolution of green lacewings (Neuroptera: Chrysopidae): a molecular supermatrix approach

We present a time‐calibrated phylogeny of the charismatic green lacewings (Neuroptera: Chrysopidae). Previous phylogenetic studies on the family using DNA sequences have suffered from sparse taxon sampling and/or limited amounts of data. Here we combine all available previously published DNA sequence data and add to it new DNA sequences generated for this study. We analysed these data in a supermatrix using Bayesian and maximum likelihood methods and provide a phylogenetic hypothesis for the family that recovers strong support for the monophyly of all subfamilies and resolves relationships among a large proportion of chrysopine genera. Chrysopinae tribes Leucochrysini and Belonopterygini were recovered as monophyletic sister clades, while the species‐rich tribe Chrysopini was rendered paraphyletic by Ankylopterygini. Relationships among the subfamilies were resolved, although with relatively low statistical support, and the topology varied based on the method of analysis. Greatest support was found for Apochrysinae as sister to Nothochrysinae and Chrysopinae, which is in contrast to traditional concepts that place Nothochrysinae as sister to the rest of the family. Divergence estimates suggest that the stem groups to the various subfamilies diverged during the Triassic‐Jurassic, and that stem groups of the chrysopine tribes diverged during the Cretaceous.     

Evolution of green lacewings (Neuroptera: Chrysopidae): an anchored phylogenomics approach

A phylogeny of green lacewings (Neuroptera: Chrysopidae) using anchored hybrid enrichment data is presented. Using this phylogenomic approach, we analysed 137 kb of sequence data (with < 10% missing) for 82 species in 50 genera of Chrysopidae under Bayesian and maximum likelihood criteria. We recovered a strongly supported tree topologically congruent with recently published phylogenies, especially relationships amongst higher‐level groups. The subfamily Nothochrysinae was recovered as paraphyletic, with one clade sister to the rest of Chrysopidae, and the second clade containing the nominal genus (Nothochrysa Navás) as sister to the subfamily Apochrysinae. Chrysopinae was recovered as a monophyletic with the monobasic Nothancylini tribe n. sister to the rest of the subfamily. Leucochrysini was recovered sister to Belonopterygini, and Chrysopini was rendered paraphyletic with respect to Ankylopterygini. Divergence times and diversification estimates indicate a major shift in rate in ancestral Chrysopini at the end of the Cretaceous, and the extensive radiation of Chrysopinae, the numerically dominant clade of green lacewings, began in the Mid‐Paleogene (c. 45 Ma).     

Comments on hexanchiform phylogeny (Pisces, Neoselachii)

The Hexanchiformes (Cow Sharks) are regarded as a monophyletic taxon. Cladistic analysis shows that among the various neoselachian taxa proposed so far as the sister group of the Hexanchiformes a sister group relationship between the Hexanchiformes and a (still unnamed) taxon comprising the Squaliformes and Pristiophoriformes appears as the most probable hypothesis. In addition, MAISEY and WOLFRAM'S (1984) concept of hexanchiform interrelationships is critically reviewed. An alternative cladogram of hexanchiform interrelationships is developed which includes Recent as well as fossil hexanchiform taxa. In this cladogram the living genera Hexancbus and Notorynchus are sister groups and both taxa together form the sister group of the Recent Heptranchias. The fossil taxa +Notidanoides, +“Hexanchus” gracilis, +Notidanodon and +Weltonia are arranged in the stem lineage of recent Hexanchiformes.
