Phylogeny and revision of the bee genus Rhinocorynura Schrottky (Hymenoptera, Apidae, Augochlorini), with comments on its female cephalic polymorphism

Phylogeny and revision of the bee genus Rhinocorynura Schrottky (Hymenoptera, Apidae, Augochlorini), with comments on its female cephalic polymorphism. A taxonomic revision and a phylogeny for the species of Rhinocorynura are provided. Six species are recognized: R. briseis, R. crotonis, R. inflaticeps and R. vernoniae stat. nov., the latter removed from synonymy with R. inflaticeps, in addition to two newly described species, R. brunnea sp. nov. and R. viridis sp. nov. Lectotypes for Halictus crotonis Ducke, 1906 and Halictus inflaticeps Ducke, 1906 are hereby designated. Another available name included in Rhinocorynura, Corynuropsis ashmeadi Schrottky, 1909, is removed from the genus and treated as species inquerenda in Augochlorini. Rhinocorynura is monophyletic in the phylogenetic analysis and the following relationships were found among its species: (R. crotonis (R. briseis ((R. brunnea sp. nov. + R. viridis sp. nov.) (R. inflaticeps + R. vernoniae)))). Biogeographic relationships within the genus and comparisons with related taxa are presented. Females of all species exhibit pronounced variation in body size, in two of them, R. inflaticeps and R. vernoniae, with structural modifications possibly linked to division of labor. Identification key and illustrations for the species are provided.

Catalogue of the type-specimens of Bolitophilidae, Diadocidiidae and Ditomyiidae (Diptera, Bibionomorpha) in the Natural History Museum, London

Catalogue of the type-specimens of Bolitophilidae, Diadocidiidae and Ditomyiidae (Diptera, Bibionomorpha) in the Natural History Museum, London. A commented list of the types of three families of Bibionomorpha - Bolitophilidae, Diadocidiidae and Ditomyiidae - housed at the Natural History Museum (London) is provided. This includes four holotypes and one paratype of five species of Bolitophilidae; one paratype and three syntypes of two species of Diadocidiidae; and 17 holotypes, 91 paratypes, four lectotypes, and fourteen paralectotypes of 38 species of Ditomyiidae. Lectotypes are designated for the Neotropical species of the ditomyiids Australosymmerus (Melosymmerus) bisetosus Edwards, 1940 and A. (M.) pediferus Edwards, 1940.

Algunos tipos de cistáceas béticas y rifeñas de los herbarios BC, MA y MAF.

We indicate nomenclatural types (lectotypes and isolectotypes) for 10 taxa of the genus Cistus, Halimium and Helianthemum described from Andalusia and northern Morocco by botanists of the first half of the 20th century such as Font Quer, Pau, Cuatrecasas and Sennen. These types are conserved in the Spanish herbaria mentioned above, and some of them belong to the exsiccatae"Iter maroccanum" and"Plantes d"Espagne". Keywords: Nomenclatural types, Cistaceae, Andalusia, northern Morocco.

Lectotypifications in Ditassa R.Br. (Apocynaceae: Asclepiadoideae)

As results of a revision of the Brazilian species of Ditassa, lectotypes for D. endoleuca Schltr., D. pauciflora Decne. and D. ramosa E. Fourn. (= D. blanchetii Decne.) are designated.

Typification of four North American club-chollas: the names of four Engelmannian species from Mexico and Southwestern United States

The names Opuntia bulbispina, O. clavata, O. emoryi and O. grahamii, originally proposed by George Engelmann between 1848 and 1856, are reviewed and typified after new findings of previously unknown voucher specimens. Original materials collected by some of the collaborators employed by Engelmann during the Mexican Boundary Survey were discovered in a loan from the Torrey Herbarium at the New York Botanical Garden (NY). Many of the materials include fragments of stems and fruits, and others include only sectioned flowers and some seeds. Particularly good descriptions of the species here concerned were published in Engelmann’s “Synopsis of the Cactaceae” in 1857, and exceptional illustrations were produced by Paulus Roetter and printed in “Cactaceae of the Boundary” in 1859. The problems surrounding some previous typifications of these names range from typification of joint lectotypes to illegitimate typifications of illustrations when original material was known to exist. The materials selected for typification were collected by the Mexican Boundary Survey and are lodged at the herbaria of the Missouri Botanical Garden (MO) and the New York Botanical Garden (NY); some are illustrations published by Engelmann.

Taxonomic and nomenclatural notes on Guatteria australis (Annonaceae)

Guatteria is the largest genus of Annonaceae, comprising ca. 300 species. The genus presents taxonomic problems, and the number of species has been overestimated. Taxonomic revision, description, comments and illustration of G. australis are presented here. As a result, 41 names have been placed in synonymy under G. australis, and three lectotypes are newly designated.

A taxonomic review of Neogriphoneura Malloch, 1924 (Diptera : Lauxaniidae), with description of three new species

The status of the Lauxaniidae genus Rhabdolauxania Hendel, 1925 is reevaluated and is synonymized under Neogriphoneura Malloch, 1924. Three new combinations, N. immaculata (Hendel, 1933), comb. nov., N. laevifrons (Hendel, 1925), comb. nov., and N. schnusei (Hendel, 1925), comb. nov. are proposed. Two lectotypes are designated. Three new species of Neogriphoneura are described: N. bispoi sp. nov., from Santa Catarina, Brazil, N. pacata sp. nov., from La Paz, Bolivia, and N. corrugata sp. nov. from British Virgin Islands. Illustrations of the head, wing, male and female terminalia are provided for the new species. This raises the number of species in the genus from the present five to eleven. A key is provided for the species of the genus.

A new species of Tontelea from Amazonian Peru and Ecuador, and notes on the Tontelea attenuata species group (Celastraceae, Hippocrateoideae)

Tontelea fuliginea differs from other species whose stamens alternate with undivided stigma-lobes by its profusely ramified, many flowered, and densely dirty-brown puberulous inflorescences. This paper also provides a synopsis and key of the group of species with alternate stamens and 3-lobed stiomas with undivided lobes (T. attenuata group). Four lectotypes are designated for previously published names: Tontelea longifolia, Tontelea micrantha, Tontelea corrugulata, and Salacia micrantha var. lancifolia.

The lauraceae collected in brazil by ludwig riedel - I

The species of Lauraceae collected by Ludwig Riedel, excluding Ocotea, are commented and contex-tualized according to the different itineraries he travelled in Brazil, from 1821 to 1836, indicating the localities and dates of collections, whenever possible. To complete this work, two diaries of Riedel have been consulted and the information from them cross-checked with the annotations found on specimen labels. An annotated list of 48 entries provides information on the status of species names and their types, currently accepted names, and collections found in different herbaria. Lectotypes for five names, Aydendron verrucosum var. attenuata, Aydendron parviflorum, Mespilodaphne parviflora, Nectandra spicata, and Oreodaphne fasciculata, are designated. The species of Ocotea collected by Riedel will be treated in part II of this series. © President and Fellows of Harvard College, 2012.

The species of Ocotea (Lauraceae) collected by Ludwig Riedel are commented and contextualized according to the different itineraries he travelled in Brazil, from 1821 to 1836, indicating the localities and dates of collections, whenever possible. To complete this work, two diaries of Riedel have been consulted and the information from them crossed-checked with the annotations found on specimen labels. An annotated list of 44 entries provides information on the status of species names and their types, currently accepted names, and collections found in different herbaria. Lectotypes for 19 names are designated, two new synonyms are proposed, as well as the new combination Ocotea estrellensis (Meisn.) P.L.R. Moraes, based on Oreodaphne estrellensis Meisn. © President and Fellows of Harvard College, 2012.
