Revision of New Zealand Orthotylinae (Insecta: Hemiptera: Miridae)

Abstract

Six genera and 11 species of Orthotylinae are now known from New Zealand. Zanchius Distant is newly recorded. One new genus, Tridiplous, and seven new species of endemic New Zealand Orthotylini are described and illustrated. Four new species are described in Tridiplous: T. burrus, T. parvapiatus, T. penmani, and T. virens, and three new species are described in Zanchius: Z. ater, Z. rubicrux, and Z. totus. Keys are provided to identify New Zealand taxa of the tribes of Orthotylinae, genera and species of Halticini, genera of Orthotylini, and species of Tridiplous and Zanchius. The bugs are illustrated with colour habitus photos, and drawings including male and female genitalia. Economic importance is discussed.     

Revision of <Emphasis Type="Italic">Heterosavia</Emphasis>, stat. nov., with notes on <Emphasis Type="Italic">Gonatogyne</Emphasis> and <Emphasis Type="Italic">Savia</Emphasis> (Phyllanthaceae)

Heterosavia (Phyllanthaceae) is segregated from Savia (tribe Bridelieae), recognized at generic rank, and placed in tribe Phyllantheae. Floral, fruit, leaf anatomical, leaf venation, and pollen characters of the neotropical taxa previously united as Savia including Gonatogyne are discussed and illustrated. Keys to the three genera and to the species of Heterosavia are presented. Four species (all new combinations), Heterosavia bahamensis, H. erythroxyloides, H. laurifolia, and H. maculata, are recognized. The new combinations Heterosavia laurifolia var. intermedia and H. maculata var. clementis are proposed. The names Heterosavia, H. erythroxyloides, H. laurifolia, Savia clementis, S. clusiifolia, S. clusiifolia var. fallax, and S. longipes are lectotypified. Distribution maps and conservation assessments (IUCN ratings) of Heterosavia species and varieties are provided.     

A synopsis of <Emphasis Type="Italic">Cohniella</Emphasis> (Orchidaceae,Oncidiinae)

A synopsis of the genus Cohniella is presented with nomenclatural updates with a discusion of diagnostic features and biogeographical data. Thirteen species and one natural hybrid are recognized. Two new species, Cohniella pendula and Cohniella biorbicularis, are described and illustrated. The following four new combinations are proposed: Cohniella binotii, Cohniella brachyphylla, Cohniella cepula, and Cohniella longifolia. Lectotypes are selected for Oncidium subulifolium, Oncidium helicanthum, Oncidium humboldtii, Oncidium jonesianum var. phaeanthum, Oncidium cepula, and Oncidium wittii. We also propose an amended lectotype for Epidendrum cebolleta and several epitypifications and new synonyms. A key to the genera of the Trichocentrum complex is presented (Appendix) as well as keys to the species of Cohniella.     

Transfers to <Emphasis Type="Italic">Simsia</Emphasis> and description of <Emphasis Type="Italic">Davilanthus</Emphasis>, a new genus of Asteraceae (Heliantheae)

Taxonomic changes are made to reflect a reassessment of morphology based on the results of molecular phylogenetic studies. A new genus, Davilanthus, is described to include six species that collectively form the sister group to Simsia, and includes the following species transferred from Viguiera: Davilanthus davilae, Davilanthus hidalgoanus, Davilanthus hypargyreus, Davilanthus huajuapanus, Davilanthus purpusii, and Davilanthus sericeus. Three species formerly placed in Viguiera ser. Grammatoglossae are transferred to Simsia: Simsia benziorum, Simsia ovata, and Simsia rhombifolia.     

A monograph of <Emphasis Type="Italic">Ascogrammitis</Emphasis>, a new genus of grammitid ferns (Polypodiaceae)

This paper describes Ascogrammitis, a new genus of grammitid ferns formerly combined under Terpsichore. Seventeen species are recognized, including five new ones: A. clavigera, A. colombiensis, A. loxensis, A. oxapampensis, and A. tungurahuae. New combinations are made for A. alan-smithii, A. anfractuosa, A. angustipes, A. athyrioides, A. clathrata, A. cuencana, A. david-smithii, A. dilatata, A. nana, A. pichinchae, A. pichinchensis, A. stuebelii, and a lectotype is chosen for Polypodium induens. A key is provided to distinguish the species, and illustrations are provided for 12 species. The genus occurs primarily in neotropical cloud forests, with the greatest diversity in the Andes. Ascogrammitis is one of two monophyletic groups of grammitid ferns that are consistently associated with Acrospermum, an epibiotic bitunicate ascomycete that produces black clavate fruiting bodies.     

Three new species,a new combination,and a neotypification in <Emphasis Type="Italic">Dahlstedtia</Emphasis> (Leguminosae,Millettieae, Papilionoideae) from South America

Three new species of Dahlstedtia, D. burkartii, D. dehiscens, and D. lewisiana, are described from South America, and their relationships with related species are discussed. Dahlstedtia burkartii, from Argentina, has pink flowers with standard straight, whereas D. dehiscens and D. lewisiana, both from Brazil, have purplish to lilac flowers with a reflexed standard petal. A new combination, Dahlstedtia peckoltii, is proposed based on Lonchocarpus peckoltii and a neotype is selected for the latter. Information about geographic distribution and phenology of the species is provided.     

Nomenclatural changes in <Emphasis Type="Italic">Lithospermum</Emphasis> (Boraginaceae) and related taxa following a reassessment of phylogenetic relationships

Lithospermum (Boraginaceae) comprises approximately 40 species in both the Old and New Worlds, with a center of diversity in the southwestern United States and Mexico. Using ten cpDNA regions, a phylogeny of Lithospermum and related taxa was reconstructed. Lithospermum (including New World and Old World species) and related New World members of Lithospermeae form a monophyletic group, with Macromeria, Onosmodium, Nomosa, Lasiarrhenum, and Psilolaemus nested among species of Lithospermum. New World Lithospermeae also is a monophyletic group, with Eurasian species of Lithospermum sister to this group. Because Lithospermum is not monophyletic without the inclusion of the other New World genera, species from these genera are transferred to Lithospermum, and appropriate nomenclatural changes are made. New combinations are Lithospermum album, Lithospermum barbigerum, Lithospermum dodrantale, Lithospermum exsertum, Lithospermum helleri, Lithospemum leonotis, Lithospermum notatum, Lithospermum oaxacanum, Lithospermum pinetorum, Lithospermum rosei, Lithospermum trinverium, and Lithospermum unicum; new names are Lithospermum chiapense, Lithospermum johnstonii, Lithospermum macromeria, Lithospermum onosmodium, Lithospermum rzedowskii, and Lithospermum turneri.     

Two new species and a new combination in <Emphasis Type="Italic">Elaphoglossum</Emphasis> sect. <Emphasis Type="Italic">Polytrichia</Emphasis> subsect. <Emphasis Type="Italic">Apoda</Emphasis> (Dryopteridaceae) from Costa Rica and Panama

Two new species, Elaphoglossum alvaradoanum and E. pendulum, are described. The first species is endemic to Cocos Island, and the second to the mountains of Costa Rica. Elaphoglossum auripilum var. longipilosum is elevated to species rank as E. longipilosum.     

Synopsis of <Emphasis Type="Italic">Mickelia</Emphasis>, a newly recognized genus of bolbitidoid ferns (Dryopteridaceae)

Our recent molecular phylogenetic study revealed a previously unrecognized clade of six species that is sister to Elaphoglossum. Within this clade, four species are currently classified in Bolbitis, one in Lomagramma, and one in Acrostichum. For this clade, we propose the name Mickelia, with M. nicotianifolia as the type species. We also make new combinations for the species in our phylogenetic study shown to belong to Mickelia (M. bernoullii, M. guianensis, M. hemiotis, M. nicotianifolia, M. oligarchica, and M. scandens) and two other species believed to belong to the clade based on morphology (M. lindigii, M. pergamentacea). A new hybrid and two new species are also described (M. ×atrans, M. furcata, and M. pradoi). In total, Mickelia consists of ten species and one hybrid. It is entirely neotropical. We provide a key to the genera of bolbitidoid ferns and a synopsis of Mickelia that gives for each species a complete synonymy, geographical distribution, comparative discussion, and illustration.     

A new species of <Emphasis Type="Italic">Mentzelia</Emphasis> section <Emphasis Type="Italic">Bartonia</Emphasis> (Loasaceae) from the Grand Canyon,Arizona

Mentzelia hualapaiensis, a new species of Mentzelia sect. Bartonia, is described from the Grand Canyon region of Arizona. The new species is closely related to M. puberula, which is found west of M. hualapaiensis along the Colorado River, and to M. oreophila, M. polita, and M. tiehmii. It shares with these species a suffrutescent shoot system characterized by a subterranean, branching caudex, multiple annual branches, and similar leaves that have shallowly lobed or toothed to entire laminas. The flowers of M. hualapaiensis differ from those of its closest relatives in having cream-white, linear to narrowly spatulate petals and staminodes, characteristics that are convergent with those of the flowers of the Chihuahuan Desert species M. humilis.     

Three new species of <Emphasis Type="Italic">Elaphoglossum</Emphasis> (Dryopteridaceae) from the Guianas

Three new species of Elaphoglossum are described from the Guianas: E. arachnidoideum, E. boudriei, and E. cremersii.     

<Emphasis Type="Italic">Eschweilera awaensis</Emphasis> and <Emphasis Type="Italic">Grias subbullata</Emphasis> (Lecythidaceae), two new species from northwestern Ecuador

Eschweilera awaensis and Grias subbullata, two new species known from the wet forests of northwestern Ecuador, are described. Eschweilera awaensis occurs in Esmeraldas, Los Ríos, and the westernmost parts of the Pichincha provinces between 25–650 m elevation. Grias subbullata, is known only from two localities in the Santo Domingo de los Tsáchilas province between 900–1670 m elevation. The new species are illustrated and their relationships with similar species are discussed.     

Notes on <Emphasis Type="Italic">Lepraria</Emphasis> s.l. (Lecanoromycetes,Ascomycota) in North America: New species,new reports,and preliminary keys

Six new species of Lepraria are described from North America: L. barbatica, L. cryophila, L. disjuncta, L. moroziana, L. terricola, and L. xanthonica. Lepraria torii is discussed and its range extended to include boreal eastern North America. Lepraria aurescens is reported as new to North America from Florida. Preliminary keys to the genus in North America are presented.     

Validation of <Emphasis Type="Italic">Neoraputia</Emphasis> (Galipeae,Rutaceae) and description of two new species from Eastern Brazil

The name Neoraputia was published without citation of the type, making it and the names of the four species transferred to it invalid. The genus name and combinations are validated here. Lectotypes are chosen for the basionyms, Aruba alba, Raputia magnifica, R. paraensis, and Raputia trifoliata. Two new species, Neoraputia micrantha and N. calliantha, from forests of eastern Bahia, Brazil, are described.     

<Emphasis Type="Italic">Grias angustipetala</Emphasis> and <Emphasis Type="Italic">G. ecuadorica</Emphasis>, two new species of Lecythidaceae from western Ecuador

Grias angustipetala and G. ecuadorica, two new species from the wet forests of western Ecuador are described. Grias angustipetala occurs in the Awá Indígenous Territory and Reserva Ecológica Cotacachi-Cayapas in the Esmeraldas and adjacent Carchi Provinces between 50–1800 m elevation. Grias ecuadorica is found in the Los Ríos and Bolívar Provinces between 70–600 m elevation. The new species are illustrated and their relationships with related species are discussed.
