The phylogenetic relationships between virus vector and other genera of macrosteline leafhoppers, including descriptions of new taxa (Homoptera: Cicadellidae: Deltocephalinae)

Abstract. Analysis of thirty-four macrosteline and twenty-eight non-macrosteline leafhopper genera (Homoptera: Cicadellidae: Deltocephalinae) suggests that the ability to transmit plant viruses has arisen on at least three separate occasions within the Macrostelini. The tribe, including the Coryphaelini syn.n. and Balcluthini, is shown to be monophyletic. A revised diagnosis of the Macrostelini is presented, together with a key to genera. Five new genera and eight new species are described: Aderganna gen.n. , Cicadabara gen.n. Kadrabolina gen.n. , Masafuera gen.n. and Scaphosteles gen.n. , Yamatotettix remanei sp.n. , Masafuera oceanica sp.n. , Aderganna aethiopica sp.n. , A.nigra sp.n. , Scaphosteles nukahiva sp.n. , Kadrabolina elongata sp.n. , K.sinuata sp.n. and K.bispinosa sp.n. Four new combinations and five new synonymies are established: Cicadabara dorsalis (Osborn) comb.n. , C.minuta (Osborn) comb.n. , C.tintorella (Osborn) comb.n. , Balclutha thea (Distant) comb.n. , B.smaragdula Matsumura as a junior synonym of B.thea (Distant) syn.n. , B.modesta Ahmed, Murtaza & Malik as a junior synonym of B.incisa (Matsumura) syn.n. , B.karachiensis Ahmed, Murtaza & Malik as a junior synonym of B.rubrostriata (Melichar) syn.n. , B.versicoloroides Ghauri as a junior synonym of B.sternalis (Distant) syn.n. and B.knighti Rao & Ramakrishnan as a junior synonym of B.sujawalensis Ahmed syn.n.     

Systematics of species referred to the genus Angiostrongylus

Based on morphological criteria of the male bursa, angiostrongylid nematodes often placed in the genus Angiostrongylus Kamensky (1905) were found to be heterogeneous, comprising species which are relegated to 5 distinct genera: Angiostrongylus Kamensky, 1905 (syn. Haemostrongylus Railliet and Henry, 1907); Parastrongylus Baylis, 1928 (syn. Pulmonema Chen, 1935, Rattostrongylus Schulz, 1951, Morerastrongylus Chabaud, 1972, Chabaudistrongylus Kontrimavichus and Delyamure, 1979); Angiocaulus Schulz, Orlov and Kutass, 1933; Gallegostrongylus Mas-Coma, 1977 (syn. Thaistrongylus Ohbayashi, Kamiya and Bhaibulaya, 1979 n. syn); and Stefanskostrongylus Drozdz, 1970. These genera all contain species located primarily in specific host groups: Angiostrongylus in carnivores; Parastrongylus in rodents (Muridae), Angiocaulus in mustelids; Rodentocaulus in rodents (Cricetinae), Gallegostrongylus in rodents (Muridae), and Stefanskostrongylus in insectivores. Species in each genus include: Angiostrongylus (A. vasorum, A. raillieti, A. chabaudi); Parastrongylus (P. tateronae, P. cantonensis, P. mackerrasae, P. sandarsae, P. sciuri, P. petrowi n. comb., P. dujardini, P. schmidti, P. costaricensis n. comb., P. malaysiensis n. comb., P. ryjikovi n. comb., P. siamensis n. comb.); Angiocaulus (A. gubernaculatus, A. ten n. comb., A. sp. Caballero, 1951); Rodentocaulus (R. ondatrae) and Gallegostrongylus (G. ibicensis, G. andersoni, G. harinasutai n. comb.). Angiostrongylus pulmonalis is likely similar to Stefanskostrongylus soricis and is transferred to this genus. Angiostrongylus minutus is removed to Stefanskostrongylus.

Encarsia or Encarsiella? – redefining generic limits based on morphological and molecular evidence (Hymenoptera,Aphelinidae)

Abstract.  The genus Encarsiella ( syn.n. ) (Hymenoptera, Chalcidoidea, Aphelinidae) is synonymized with Encarsia on the basis of molecular and morphological characters. A phylogenetic analysis was conducted of the D2 expansion region of the 28S ribosomal DNA including thirty-eight Encarsia species. Our phylogenetic analysis revealed a polyphyletic origin of Encarsiella and confirmed the results of earlier analyses indicating the paraphyly of Encarsia . Four species are described as new ( Encarsia bifasciata sp.n. , E. caelata sp.n. , E. obliqua sp.n. and E. pilosa sp.n. ). The following species are transferred from Encarsiella to Encarsia : Encarsia aleurodici ( Girault, 1916 ) comb.n. , E. amabilis ( Huang & Polaszek, 1998 ) comb.n. , E. boswelli ( Girault, 1915 ) comb.n. , E. magniclava ( Girault, 1915 ) comb.n. , E. narroi Gómez & García comb.n. , E. nepalensis ( Polaszek & Hayat, 1992 ) comb.n. , E. noyesi ( Hayat, 1983 ) comb.n. , E. pithecura ( Polaszek, 1999 ) comb.n. , E. tachii ( Polaszek & Hayat, 1992 ) comb.n. , E. taiwanensis ( Chou & Chou, 1994 ) comb.n. and E. tamaulipeca ( Myartseva & Coronado-Blanco, 2002 ) comb.n. The generic limits of Encarsia are re-defined based on a re-assessment of morphological characters, and the results are discussed with respect to the current classification of the aphelinid subfamily Coccophaginae.     

A molecular phylogeny of the Chalcidoidea (Hymenoptera)

Chalcidoidea (Hymenoptera) are extremely diverse with more than 23,000 species described and over 500,000 species estimated to exist. This is the first comprehensive phylogenetic analysis of the superfamily based on a molecular analysis of 18S and 28S ribosomal gene regions for 19 families, 72 subfamilies, 343 genera and 649 species. The 56 outgroups are comprised of Ceraphronoidea and most proctotrupomorph families, including Mymarommatidae. Data alignment and the impact of ambiguous regions are explored using a secondary structure analysis and automated (MAFFT) alignments of the core and pairing regions and regions of ambiguous alignment. Both likelihood and parsimony approaches are used to analyze the data. Overall there is no impact of alignment method, and few but substantial differences between likelihood and parsimony approaches. Monophyly of Chalcidoidea and a sister group relationship between Mymaridae and the remaining Chalcidoidea is strongly supported in all analyses. Either Mymarommatoidea or Diaprioidea are the sister group of Chalcidoidea depending on the analysis. Likelihood analyses place Rotoitidae as the sister group of the remaining Chalcidoidea after Mymaridae, whereas parsimony nests them within Chalcidoidea. Some traditional family groups are supported as monophyletic (Agaonidae, Eucharitidae, Encyrtidae, Eulophidae, Leucospidae, Mymaridae, Ormyridae, Signiphoridae, Tanaostigmatidae and Trichogrammatidae). Several other families are paraphyletic (Perilampidae) or polyphyletic (Aphelinidae, Chalcididae, Eupelmidae, Eurytomidae, Pteromalidae, Tetracampidae and Torymidae). Evolutionary scenarios discussed for Chalcidoidea include the evolution of phytophagy, egg parasitism, sternorrhynchan parasitism, hypermetamorphic development and heteronomy.     

Revision of Microlaimidae, Erection of Molgolaimidae fam.n., and Remarks on the Systematic Position of Paramicrolaimus (Nematoda, Desmodorida)

The family Microlaimidae contains Bolbolaiminae subfam.n. (Bolbolaimus syn. Pseudomicro-laimus) and Microlaiminae ( Calomicrolaimus, Ixonema and Microlaimus ). The new family Molgolaimidae contains Aponematinae subfam.n. ( Aponema gen.n.) and Molgolaiminae subfam.n. ( Molgolaimus and Prodesmodora ). The main differentiating characters applied are: structures of the head region, shape of the oesophagus, position of the excretory pore, shape of the tail, structure of the gonads and ornamentation of the cuticle. The significance of porids and preanal supplements as distinguishing characters is, discussed. Microlaimidae are closely related to Desmodoridae; Molgolaimidae related to Spiriniidae. Paramicrolaimus is transferred from Microlaimidae to Spiriniidae.–Six species from the Øresund, Denmark, are redescribed: Microlaimus punctulatus Gerlach, 1950 and M. acinaces Warwick & Piatt, 1973; Aponema torosus (Lorenzen, 1973) gen.n., comb.n. (syn. Microlaimus torosus Loren-zen, 1973); Molgolaimus allgeni (Gerlach, 1950) comb.n. (syn. Microlaimus allgeni Gerlach, 1950) and M. turgofrons (Lorenzen, 1972) comb.n. (syn. Microlaimus turgofrons Lorenzen, 1972); Paramicrolaimus spirulifer Wieser, 1959.     

The spider family Selenopidae (Arachnida, Araneae) in Australasia and the Oriental Region

We relimit and revise the family Selenopidae to include four new genera and 27 new species from Australia and the Oriental Region. The family is redefined, as are the genera Anyphops Benoit, Garcorops Corronca, Hovops Benoit, Selenops Latreille, and Siamspinops Dankittipakul & Corronca, to accommodate the new genera and to correct previous inconsistencies in the diagnoses and definitions of the aforementioned genera. The species of Selenops that occur throughout India and China are also reviewed. Three species occur in China: Selenops bursarius Karsch 1879, also known from Japan, Korea and Taiwan, Selenops ollarius Zhu, Sha, & Chen 1990, and Selenops radiatus Latreille 1819, the type of the genus and most widespread selenopid. Selenops cordatus Zhu, Sha & Chen syn. n. is recognized as a junior synonym of Selenops radiatus. Amamanganopsgen. n. is monotypic, with Amamanganops baginawasp. n. (♀; from the Philippines). Godumopsgen. n. is monotypic, with Godumops caritussp. n. (♂; from Papua New Guinea). Karaopsgen. n. occurs throughout Australia and includes 24 species. A new combination is proposed for Karaops australiensis (L. Koch 1875) comb. n. (ex. Selenops), and the new species: Karaops gangariesp. n. (♀, ♂), Karaops monteithisp. n. (♀), Karaops alanlongbottomisp. n. (♂), Karaops keithlongbottomisp. n. (♂), Karaops larryoosp. n. (♂), Karaops jarritsp. n. (♂,♀), Karaops marrayagongsp. n. (♀), Karaops ravenisp. n.

(♀, ♂), the type species Karaops ellenaesp. n. (♂,♀), Karaops jenniferaesp. n. (♀), and Karaops dawarasp. n. (♀).The genus Makdiopsgen. n. contains five species from India and Nepal. A new combination is proposed for Makdiops agumbensis (Tikader 1969), comb. n., Makdiops montigenus (Simon 1889), comb. n., Makdiops nilgirensis (Reimoser 1934) comb. n.,(ex. Selenops). Also, there are two new species the type of the genus Makdiops mahishasurasp. n. (♀; from India), and Makdiops shivasp. n. (♀). The genus Pakawopsgen. n. is monotypic. A new combination is proposed for Pakawops formosanus (Kayashima 1943) comb. n. (ex. Selenops), known only from Taiwan. A new combination is proposed for Siamspinops aculeatus (Simon)comb. n. (ex. Selenops). The distribution and diversity of the studied selenopid fauna is discussed. Finally, keys are provided to all of the selenopid genera and to the species of Karaopsgen. n.and Makdiopsgen. n.     

A new genus of oak gallwasps, Zapatella Pujade-Villar & Melika, gen. n., with a description of two new species from the Neotropics (Hymenoptera, Cynipidae, Cynipini)

A new genus of cynipid oak gallwasp, Zapatella Pujade-Villar & Melika, gen. n. (Hymenoptera: Cynipidae: Cynipini), with two new species, Zapatella grahami Pujade-Villar & Melika, sp. n. and Zapatella nievesaldreyi Melika & Pujade-Villar, sp. n., is described from the Neotropics. Zapatella grahami,known only from the sexual generation,induces galls in acorns of Quercus costaricensis and is currently known only from Costa Rica. Zapatella nievesaldreyi, known only from the asexual generation, induces inconspicuous galls in twigs of Quercus humboldtii, and is known only from Colombia. Diagnostic characters for both new species are given in detail. Five Nearctic species are transferred from Callirhytis to Zapatella: Zapatella cryptica (Weld), comb. n., Zapatella herberti (Weld), comb. n., Zapatella oblata (Weld), comb. n., Zapatella quercusmedullae (Ashmead), comb. n.,Zapatella quercusphellos (Osten Sacken), comb. n. (= Zapatella quercussimilis (Bassett), syn. n.). A key based on adults for the species belonging to Zapatella is also given. Generic limits and morphological characteristics of Zapatella and closely related genera are discussed.     

Generic revision and phylogeny of Microweiseinae (Coleoptera: Coccinellidae)

The monophyly and phylogenetic relationships of the subfamily Microweiseinae were investigated. Twenty‐three in‐group taxa, representing all known genera of Microweiseinae (except for Microcapillata Gordon) were included in a cladistic analysis, based on 45 adult morphological characters. The parsimony analysis of the resulting data matrix supported the monophyly of Microweiseinae, Carinodulini, Serangiini and Microweiseini (inclusive of Sukunahikonini). The recognition of Sukunahikonini renders Microweiseini paraphyletic, and consequently both tribes were synonymized, retaining Microweiseini as a senior family‐group name ( syn.n. ). Genera and tribes of Microweiseinae are diagnosed thoroughly, illustrated and keys to their identification are provided. The following nomenclatural changes were made: Hikonasukuna Sasaji and Orculus Sicard are synonymized with Scymnomorphus Weise ( syn.n. ); Gnathoweisea Gordon is synonymized with Microweisea Cockerell ( syn.n. ); Hikonasukuna monticola Sasaji and Orculus castaneus Sicard are transferred to Scymnomorphus ( comb.n. ); Smilia planiceps Casey, Gnathoweisea hageni Gordon, Gnathoweisea ferox Gordon, Gnathoweisea micula Gordon and Gnathoweisea texana Gordon are transferred to Microweisea ( comb.n ). Three new genera are described: Allenius gen.n. for Allenius californianus sp.n. (type species) from Mexico and Allenius iviei sp.n. from U.S.A.; Gordoneus gen.n. (type species Gnathoweisea schwarzi Gordon from U.S.A.); and Cathedrana gen.n. (type species Cathedrana natalensis sp.n. from South Africa). The first African member of Carinodulini, Carinodulina ruwenzorii sp.n. is described. The genera Microweisea, Coccidophilus, Serangium and Delphastus are well‐known predators of sternorrynchous Hemiptera, such as scale insects (Diaspididae) and whiteflies (Aleyrodidae), and play a significant role in agricultural ecosystems as biocontrol agents. Host data and biological records are summarized for each genus.     

Phylogenetic relationships between the families of recent Thysanoptera (Insecta)

One family, the Phlaeothripidae, is recognized in the suborder Tubulifera, whereas extant species of Terebrantia are classified into seven families: Uzelothripidae, Merothripidae, Aeolothripidae, Adiheterothripidae, Fauriellidae (stat. n.), Heterothripidae and Thripidae. A phylogenetic analysis of the relationships between these families is given, based on consideration of 35 imaginal characters; however, the relationships of Uzelothripidae and Phlaeothripidae to the rest of the Thysanoptera remain equivocal. The Phlaeothripidae are either derived independently from Protothysanoptera, or else are the sister-group of the Thripidae, the most specialized family of Terebrantia.
Diagnostic characters, diversity, distribution and relationships of each family are discussed. Keys to family and, in Fauriellidae, to genus are provided. Holarthrothrips Bagnall (= Adiheterothrips Ramakrishna, syn. n.) and Oligothrips Moulton are removed from Heterothripidae to Adiheterothripidae and Fauriella Hood, Opisthothrips Hood and Ropotamothrips Pelikan (= Osmanothrips Priesner, syn. n.) from Heteromripidae to Fauriellidae (stat. n.). These transfers leave Aulacothrips Hood, Heterothrips Hood and Scutothrips Stannard as the only genera in Heterothripidae.     

Phylogeny,character evolution and tribal classification in Crambinae and Scopariinae (Lepidoptera,Crambidae)

Crambinae (2047 spp.) and Scopariinae (577 spp.) are two major groups of pyraloid moths with a worldwide distribution. Their larvae feed predominantly on Poales and Bryophyta, with many cereal crop pests. We present the first molecular phylogeny of the two groups based on five nuclear genes and one mitochondrial gene (total = 4713 bp) sampled for 58 crambine species representing 56 genera and all tribes, 33 scopariine species representing 12 genera, and species in several other crambid lineages. Maximum likelihood and Bayesian analyses of the molecular data resolve suprageneric relationships in Crambinae and Scopariinae, whereas relationships between these and other subfamilies remain ambiguous. Crambinae and Scopariinae are each recovered as monophyletic groups, and Erupini, formerly regarded as an ingroup of Midilinae, is recovered as a possible sister group of Crambinae. The tree topology suggests the following two major changes within Crambinae: Prionapterygini Landry syn.n. of Ancylolomiini Ragonot stat. rev. and Myelobiini Minet syn.n. of Chiloini Heinemann. Argyriini Munroe is monophyletic after the transfer of Pseudocatharylla Bleszynski and Vaxi Bleszynski to Calamotrophini. Crambini, Diptychophorini and Haimbachiini are monophyletic after the exclusion of Ancylolomia Hübner, Euchromius Guenée, Micrelephas Dognin and Miyakea Marumo from Crambini, as well as Microchilo Okano from Diptychophorini. Euchromiini tribe n. is described for Euchromius. Microcramboides Bleszynski syn.n. and Tortriculladia Bleszynski syn.n. are synonymized with Microcrambus Bleszynski. In Scopariinae, Caradjaina Leraut syn.n. and Cholius Guenée syn.n. are synonymized with Scoparia Haworth, and, in addition, Dasyscopa Meyrick syn.n. , Dipleurinodes Leraut syn.n. and Eudipleurina Leraut syn.n. are synonymized with Eudonia Billberg. Micraglossa melanoxantha (Turner) (Scoparia) comb.n. is proposed as a new combination. We analysed 27 morphological characters of wing venation, tympanal organs, male and female genitalia, as well as host plant data and egg‐laying behaviour. The ancestral character‐state reconstructions confirmed previous apomorphies and highlighted new apomorphies for some of the newly recovered clades. The derived, nonadhesive egg‐dropping behaviour is found to have evolved at least twice in Crambinae and is associated with the use of Pooideae as host plants. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:1A84282D‐930A‐4C32‐8340‐D681BFF27A12 .

Australian gall-inducing scale insects on Eucalyptus: revision of Opisthoscelis Schrader (Coccoidea, Eriococcidae) and descriptions of a new genus and nine new species

We revise the genus Opisthoscelis Schrader, and erect the genus Tanyscelisgen. n. with Opisthoscelis pisiformis Froggatt as its type species. Species of both genera induce sexually dimorphic galls on Eucalyptus (Myrtaceae) in Australia, with Opisthoscelis subrotunda Schrader also in Papua New Guinea. We synonymise the following taxa (junior synonym with senior synonym): Opisthoscelis fibularis Froggatt, syn. n. with Opisthoscelis spinosa Froggatt; Opisthoscelis recurva Froggatt, syn. n. with Opisthoscelis maculata Froggatt; Opisthoscelis globosa Froggatt, syn. n. (= Opisthoscelis ruebsaameni Lindinger) with Opisthoscelis convexa Froggatt; and Opisthoscelis mammularis Froggatt, syn. n. with Opisthoscelis verrucula Froggatt. We transfer seven Opisthoscelis species to Tanyscelis as Tanyscelis conica (Fuller), comb. n., Tanyscelis convexa (Froggatt), comb. n., Tanyscelis maculata (Froggatt), comb. n., Tanyscelis maskelli (Froggatt), comb. n., Tanyscelis pisiformis (Froggatt), comb. n., Tanyscelis spinosa (Froggatt), comb. n., and Tanyscelis verrucula (Froggatt), comb. n. We redescribe and illustrate the adult female of each named species of Opisthoscelis for which the type material is known, as well as the first-instar nymph of the type species of Opisthoscelis (Opisthoscelis subrotunda) and Tanyscelis (Opisthoscelis pisiformis). We describe four new species of Opisthoscelis: Opisthoscelis beardsleyi Hardy & Gullan, sp. n., Opisthoscelis thurgoona Hardy & Gullan, sp. n., Opisthoscelis tuberculataHardy & Gullan, sp. n., and Opisthoscelis ungulifinis Hardy & Gullan, sp. n., and five new species of Tanyscelis: Tanyscelis grallator Hardy & Gullan, sp. n., Tanuscelis megagibba Hardy & Gullan, sp. n., Tanyscelis mollicornuta Hardy & Gullan, sp. n., Tanyscelis tripocula Hardy & Gullan, sp. n., and Tanyscelis villosigibba Hardy & Gullan, sp. n. We designate lectotypes for Opisthoscelis convexa, Opisthoscelis fibularis, Opisthoscelis globosa Froggatt, Opisthoscelis maculata, Opisthoscelis mammularis, Opisthoscelis maskelli, Opisthoscelis pisiformis, Opisthoscelis recurva, Opisthoscelis serrata, Opisthoscelis spinosa, and Opisthoscelis verrucula. As a result of our taxonomic revision, Opisthoscelis has six species and Tanyscelis has 12 species. We describe the galls of females for all 18 species and galls of males for 10 species of Opisthoscelis and Tanyscelis, and provide photographs of the galls for most species. A key to the adult females of the species of both genera is included.     

A new genus of Chlidanotini (Lepidoptera, Tortricidae) from New Caledonia, with a key to genera and check-list of species

Abstract Iconostigma gen.n., with included species tryphaenu sp.n. (typespecies) and morosa sp.n., is described from New Caledonia. A key to males of the world genera and a check-list of the world species of Chlidanotini are provided. The relationship of the Chlidanotini to the Polyorthini and Hilarographini is discussed, with particular reference to Iconostigma . It is suggested that the hair-pencils of the eighth abdominal segment, and the invaginations in the male valvae into which each hair-pencil is inserted, are apomorphic characters which unite these three tribes. Panegyru Diakonoff is transferred to the Tortricini and Polemograptis flavicostana (Walsingham) is transferred to Panegyra , comb.n. Archimaga euplocamis Meyrick is synonymized with Metrernis ochrolina Meyrick, syn.n.     

Phylogeny and classification of the Phengaris–Maculinea clade (Lepidoptera: Lycaenidae): total evidence and phylogenetic species concepts

Abstract.  Total evidence analysis, based on a combination of morphological and ecological characters with two mitochondrial sequences (cytochrome c oxidase subunits I and II) and one nuclear (elongation factor-1α) sequence, provides a new phylogeny of the uniquely obligate ant parasitic Phengaris–Maculinea butterflies. The clade, including all species of Maculinea and Phengaris , is very stable and well supported. However, various analyses suggest that either Phengaris or Maculinea is not monophyletic with regard to the other, which necessitates generic reclassification of the clade. Application of the diagnostic and monophyletic 'phylogenetic' species concepts leads to species-level reclassification, including ten species ( P. alcon comb.n. including ' P. rebeli ', P. daitozana , P. albida , P. atroguttata , P. kurentzovi comb.n. , P. nausithous comb.n. , P. teleius comb.n. , P. arion comb.n. , P. arionides comb.n. , P. takamukui comb.n .) and one unresolved metaspecies (' P. cyanecula ' comb.n .) in four monophyletic species groups. The existence of further or additional cryptic species is possible within P. nausithous and P. teleius . Maculinea Van Eecke, 1915 syn.n. is considered a junior synonym of Phengaris Doherty, 1891.     

The genus Antillothrips Stannard, with descriptions of two new species (Thysanoptera: Phlaeothripidae)

Abstract. The genus Antillothrips Stannard ( Elatea Faure, syn.n.) is redefined with a key to the ten species: australis sp.n.; exastis (Ananthakrishnan & Kudo) stat.n. comb.n.; cingulatus (Hood) (= Haplothrips (Hindsiana) sakimurai Moulton syn.n.; Xenothrips opacus Ananthakrishnan & Kudo syn.n.); graminellus Ananthakrishnan & Jagadish; hartwigi sp.n.; malabaricus (Ananthakrishnan); micropterus Pitkin; nayari (Ananthakrishnan); stannmdi (Faure) comb.n.; varius (Ananthakrishnan & Jagadish). Lectotypes are designated for opacus and exastis.     

Redefinition of the aphid genus Sitobion Mordvilko (Hemiptera: Aphididae) based on cladistic analyses, with emphasis on North American species

A hypothesis of monophyly for the aphid genus Sitobion is tested using cladistics. A diverse sample of thirty Sitobion species from Africa, Asia, Europe and North America were included, along with six species of Macrosiphum , eight new species similar to some Sitobion , one species of Illinoia , and Dysaphis tulipae (Boyer de Fonscolombe) as outgroup . A matrix of forty-seven taxa and forty-eight characters was analysed in paup , resulting in a set of thirty-nine equally parsimonious cladograms. Despite a high degree of homoplasy in the data, the results show that Sitobion is not a monophyletic group. The endemic North American species, along with two pteridophyte-feeding species from Europe, clearly belong to a separate lineage from the other Eurasian and African species. The endemic North American species are more closely related to the type species of Macrosiphum and Illinoia than to Sitobion avenae (Fabr.), the type species of Sitobion . Two species are placed as junior synonyms of Sitobion alopecuri (Takahashi): Macrosiphum (Sitobion) salicicornii Richards, syn.n. and Sitobion sylvestri Hille Ris Lambers; syn.n. Twelve species previously listed in Sitobion are placed in Macrosiphum with six new combinations: Macrosiphum adianti (Oestlund); Macrosiphum clydesmithi Robinson, comb.n.; Macrosiphum cystopteris Robinson; Macrosiphum dryopteridis (Holman), comb.n.; Macrosiphum equiseti (Holman), comb.n.; Macrosiphum insularis (Pergande); Macrosiphum lambi Robinson, comb.n.; Macrosiphum ptericolens Patch; Macrosiphum pteridis Wilson, Macrosiphum rhamni (Clarke); Macrosiphum walkeri Robinson, comb.n.; Macrosiphum woodsiae Robinson, comb.n. Two synonyms are reinstated as valid species: Macrosiphum occidentalis (Essig) and Macrosiphum pteridis Wilson.     

Systematics and morphological evolution within the moss family Bryaceae: a comparison between parsimony and Bayesian methods for reconstruction of ancestral character states

The Bryaceae are a large cosmopolitan moss family including genera of significant morphological and taxonomic complexity. Phylogenetic relationships within the Bryaceae were reconstructed based on DNA sequence data from all three genomic compartments. In addition, maximum parsimony and Bayesian inference were employed to reconstruct ancestral character states of 38 morphological plus four habitat characters and eight insertion/deletion events. The recovered phylogenetic patterns are generally in accord with previous phylogenies based on chloroplast DNA sequence data and three major clades are identified. The first clade comprises Bryum bornholmense, B. rubens, B. caespiticium, and Plagiobryum. This corroborates the hypothesis suggested by previous studies that several Bryum species are more closely related to Plagiobryum than to the core Bryum species. The second clade includes Acidodontium, Anomobryum, and Haplodontium, while the third clade contains the core Bryum species plus Imbribryum. Within the latter clade, B. subapiculatum and B. tenuisetum form the sister clade to Imbribryum. Reconstructions of ancestral character states under maximum parsimony and Bayesian inference suggest fourteen morphological synapomorphies for the ingroup and synapomorphies are detected for most clades within the ingroup. Maximum parsimony and Bayesian reconstructions of ancestral character states are mostly congruent although Bayesian inference shows that the posterior probability of ancestral character states may decrease dramatically when node support is taken into account. Bayesian inference also indicates that reconstructions may be ambiguous at internal nodes for highly polymorphic characters.
