Reappraisal of the genus Taumacera Thunberg with descriptions of two new species from South-East Asia (Coleoptera: Chrysomelidae: Galerucinae)

The galerucine genus Taumacera Thunberg is reviewed. Platyxantha Baly is placed in synonymy with Taumacera . The Taumacera deusta species-group is defined and two new species are described in this group: Taumacera mohamedsaidi from Borneo and Taumacera evi from Peninsular Malaysia and Sumatra. A new name, Taumacera seminigra , is provided for Taumacera nigripennis (Jacoby 1900a), nec Jacoby 1884, and Taumacera martapurensis Mohamedsaid is synonymised with Taumacera sucki Weise. A key is given for the deusta species-group and a revised checklist presented for all Taumacera species.

The braconid genus Alysia (Hymenoptera): a description of the subgenera and a revision of the subgenus Alysia

ABSTRACT. The forty-two species included in Alysia are divided into two subgenera based on the shape of the ovipositor. Four species-groups are proposed for Alysia (Alysia) and three for Alysia (Anarcha). The species of the subgenus Alysia are revised, with emphasis on the Nearctic fauna, and eleven new species are described. Seven new synonyms and ten new combinations are proposed. Epidista is transferred from synonymy under Alysia to synonymy under Tanycarpa. A new name Gnathopleura quadridentata nom.n . is proposed for G.nigripennis (Brues), a junior secondary homonym of G.nigripennis (Thomson).     

Phylogeny and taxonomic revision of all genera of Conopidae (Diptera) based on morphological data

All global genera of the fly family Conopidae are revised here. A cladistic analysis of 117 morphological characters recorded from 154 species, including representatives of 59 genera and subgenera, recovers a phylogenetic hypothesis for the family. This hypothesis is used as the basis of a new classification for the family. Both Sicini and Zodionini are removed from Myopinae and elevated to subfamilial status. A new tribe, Thecophorini, is proposed within Myopinae to accommodate Thecophora, Scatoccemyia, and Pseudoconops. Two genera, Pseudomyopa and Parazodion, are removed from Dalmanniinae and placed in Myopinae and Zodioninae, respectively. Conopinae is divided into 11 tribes, seven of which are newly described (Asiconopini, Caenoconopini, Gyroconopini, Microconopini, Neoconopini, and Siniconopini). Some examined species are transferred to different or new genera and subgenera. A new genus, Schedophysoconops gen. nov. , and subgenus Asiconops (Aegloconops) subgen. nov. within Conopinae are described. A review of character evolution and phylogeography is included in light of the new classification. A catalogue of all genus‐group names is included with new emendations noted.     

New insights into skeletal morphology of the oldest known silicoflagellates: Variramus, Cornua and Gleserocha gen. nov.

Two of the oldest known silicoflagellate-bearing sediments, lower Albian at Ocean Drilling Program Site 693 in the Weddell Sea of Antarctica and Santonian in the Devon Island sequence of the Canadian Archipelago, are re-examined with a focus on silicoflagellate genera Variramus, Cornua, and Gleserocha that lack basal rings, a feature appearing during late Santonian/early Campanian time within the genus Corbisema. The extraordinary variability of Variramus aculeifera is studied, and a new genus Gleserocha is proposed for taxa with apical structures made of three struts, but without pikes. This new genus includes previously described Variramus wisei and Cornua tapiae and new species G. harrisonii, and is here proposed as a genus transitional between Variramus and Cornua. Two unusual new species of Cornua, C. deflandrei and C. witkowskiana, are also described and a revised terminology is proposed for the skeletal components of Cornua and closely related genera.     

Multigene phylogenetic analysis of the Trichomonascus, Wickerhamiella and Zygoascus yeast clades, and the proposal of Sugiyamaella gen. nov. and 14 new species combinations

Relationships among species assigned to the ascosporic yeast genera Sporopachydermia, Stephanoascus, Trichomonascus, Wickerhamiella and Zygoascus, and to the associated anamorphic genera Arxula, Blastobotrys, Sympodiomyces and Trigonopsis, were determined from phylogenetic analyses of gene sequences from the nearly complete large-subunit rRNA gene, the mitochondrial small-subunit rRNA gene, and cytochrome oxidase II. The genus Stephanoascus is polyphyletic, resulting in reassignment of two species to the older genus Trichomonascus and the third to Sugiyamaella gen. nov. (type species Sugiyamaella smithiae). The genera Sporopachydermia, Wickerhamiella and Zygoascus appear to be monophyletic. The species Pichia ofunaensis and P. tannicola are proposed for transfer to Zygoascus. Arxula, Blastobotrys and Sympodiomyces are members of the Trichomonascus clade, with the genus Blastobotrys having taxonomic priority for anamorphic states. Trigonopsis variabilis and three species of Candida represent a distinct clade. From the foregoing gene sequence analyses, the new ascosporic genus Sugiyamaella is proposed, as are 14 new species combinations and the new family Trichomonascaceae.     

A worldwide phylogenetic classification of the Poaceae (Gramineae) III: An update

We present an updated worldwide phylogenetic classification of Poaceae with 11 783 species in 12 subfamilies, 7 supertribes, 54 tribes, 5 super subtribes, 109 subtribes, and 789 accepted genera. The subfamilies (in descending order based on the number of species) are Pooideae with 4126 species in 219 genera, 15 tribes, and 34 subtribes; Panicoideae with 3325 species in 242 genera, 14 tribes, and 24 subtribes; Bambusoideae with 1698 species in 136 genera, 3 tribes, and 19 subtribes; Chloridoideae with 1603 species in 121 genera, 5 tribes, and 30 subtribes; Aristidoideae with 367 species in three generaand one tribe; Danthonioideae with 292 species in 19 generaand 1 tribe; Micrairoideae with 192 species in nine generaand three tribes; Oryzoideae with 117 species in 19 genera, 4 tribes, and 2 subtribes; Arundinoideae with 36 species in 14 genera and 3 tribes; Pharoideae with 12 species in three generaand one tribe; Puelioideae with 11 species in two generaand two tribes; and the Anomochlooideae with four species in two generaand two tribes. Two new tribes and 22 new or resurrected subtribes are recognized. Forty-five new (28) and resurrected (17) genera are accepted, and 24 previously accepted genera are placed in synonymy. We also provide an updated list of all accepted genera including common synonyms, genus authors, number of species in each accepted genus, and subfamily affiliation. We propose Locajonoa, a new name and rank with a new combination, L. coerulescens. The following seven new combinations are made in Lorenzochloa: L. bomanii, L. henrardiana, L. mucronata, L. obtusa, L. orurensis, L. rigidiseta, and L. venusta.     

A rearrangement of the family Tethyidae (Porifera Hadromerida) with establishment of new genera and description of two new species

The discovery of new species, a study of the type material of already described species and an analysis of the literature data call for an extensive rearrangement of the Family Tethyidae, whose last revision dates from Burton (1924). The rearrangement proposed here attributes to the Family eight genera: Tethya Lam. (type genus), Burtonitethya gen nov. , Columnitis Schmidt, Halicomeies Topsent, Stellitethya gen. nov., Tectnitethya gen. nov., Tethycometes gen. nov . and Xenospongia Gray. The genus Aaptos is excluded from the Tethyidae. Three of the new genera have been established for species previously attributed to the genus Tethya and two are new: Burtonitethya gemmiformis (Burton & Rao) and Tethycometes sibogae sp. nov . Five species, previously attributed to Tethya , are considered 'incertae sedis'. An analytical key and discussion of the evolution of the family are included.

Three new genera of Leptophlebiidae (Ephemeroptera) from New Zealand

Abstract

Three new genera—Austroclima, Mauiulus, and Cryophlebia—are established for species of Leptophlebiidae from New Zealand. The following new combinations are included: Austroclima sepia (Phillips) and Cryophlebia aucklandensis (Peters). Atalophlebioides sepia is redescribed as Austroclima sepia and a neotype is designated. Two new species, Austroclima jollyae and Mauiulus luma, are described. All life stages are described, and the relationships of each genus are discussed. Keys are given to male and female imagos, subimagos, and nymphs of each species, and to all New Zealand genera with species previously placed in Atalophlebioides.     

A synopsis of the sawflies (Hymenoptera: Symphyta) of America south of the United States: introduction, Xyelidae, Pamphiliidae, Cimbicidae, Diprionidae, Xiphydriidae, Siricidae, Orussidae, Cephidae

Abstract Eight families of Symphyta for the Western Hemisphere south of the United States are reviewed: Xyelidae (one genus, two species), Pamphiliidae (one genus, four species), Cimbicidae (five genera, nine species), Diprionidae (three genera, thirteen species), Xiphydriidae (four genera, seventeen species), Siricidae (six genera, nine species), Orussidae (five genera, twelve species), and Cephidae (one genus, one species). New taxa are Acantholyda nigrostigmata (Pamphiliidae); Zadiprionfalsus, Neodiprion bicolor, N.equalis, N.omosus (Diprionidae); Derecyrta circularis, Steirocephala lateralba (Xiphydriidae); Sirotremex, S.flammeus (Siricidae); and Ophrynopus depressatus, O.plaumanni (Orussidae). Lopesiana is a new name for Lopesia Conde (Cimbicidae). Three new combinations and six new synonyms are proposed. The Xyelidae, Pamphiliidae, Diprionidae, Siricidae and Cephidae are primarily northern groups with southern extensions into Mexico, Central America and/or Cuba. The Cimbicidae, Xiphydriidae and Orussidae are more generally distributed throughout the neotropics. Keys to families, genera and species are provided.     

Phylogeny and classification of Muscini (Diptera, Muscidae)

Worldwide in distribution, the tribe Muscini comprises 21 accepted genera and about 350 species. In the present study, a cladistic analysis based upon adult morphological characters is carried out in order to discuss the monophyly of the tribe and its genera, the intergeneric relationships and, in some cases, also the intrageneric relationships. As a result, Muscini is supported as a monophyletic tribe sister-group of Stomoxyini. Except for Morellia Robineau-Desvoidy, Curranosia Paterson, and Eudasyphora Townsend, all the remaining genera are monophyletic. The results are dubious for Polietes Rondani, which was then provisionally kept unchanged. Morellia was broadened to include the Neotropical endemic genera Parapyrellia Townsend, Trichomorellia Stein, and Xenomorellia Malloch. Therefore, a new classification is proposed for Morellia in which it is divided into four subgenera: Morellia s.s. , Parapyrellia , Trichomorellia , and Xenomorellia . Furthermore, the previously proposed subgenus Dasysterna Zimin is given new status as a genus; however, as it is preoccupied by Dasysterna Dejean, the new replacement name Ziminellia nom. nov. is proposed herewith. Eudasyphora was found to be a paraphyletic group relative to Dasyphora Robineau-Desvoidy; both genera are hence synonymized, and Dasyphora is classified in three subgenera: Dasyphora s.s. , Eudasyphora , and Rypellia Malloch. The analysis demonstrated that the traditional classification of Musca Linnaeus into subgenera is artificial and, moreover, that the use of characters from male genitalia could be strongly informative for classifying the genus in phylogeny-supported species groups. Finally, the new classification proposal for Muscini recognizes 18 genera and, furthermore, two undescribed genus-ranked taxa are indicated.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 149 , 493–532.

Phylogeny of split‐footed lacewings (Neuroptera,Nymphidae), with descriptions of new Cretaceous fossil species from China

A phylogeny of the lacewing family Nymphidae based on morphology and DNA sequences is presented including representatives of all living genera and selected fossil genera. Widely distributed Jurassic and Cretaceous genera gave rise to recent taxa now restricted to Australasia. Two previously defined clades (i.e. Nymphinae and Myiodactylinae) were recovered and reflect the diverging adult and larval morphology of members of these two subfamilies. From Chinese Cretaceous deposits, a new genus (Spilonymphes gen. nov.) is described with one new species, as well as new species described in the genera Baissoleon Makarkin and Sialium Westwood.
