Molecular phylogeny of advanced snakes (Serpentes, Caenophidia) with an emphasis on South American Xenodontines: a revised classification and descriptions of new taxa

We present a molecular phylogenetic analysis of caenophidian (advanced) snakes using sequences from two mitochondrial genes (12S and 16S rRNA) and one nuclear (c-mos) gene (1681 total base pairs), and with 131 terminal taxa sampled from throughout all major caenophidian lineages but focussing on Neotropical xenodontines. Direct optimization parsimony analysis resulted in a well-resolved phylogenetic tree, which corroborates some clades identified in previous analyses and suggests new hypotheses for the composition and relationships of others. The major salient points of our analysis are: (1) placement of Acrochordus, Xenodermatids, and Pareatids as successive outgroups to all remaining caenophidians (including viperids, elapids, atractaspidids, and all other "colubrid" groups); (2) within the latter group, viperids and homalopsids are sucessive sister clades to all remaining snakes; (3) the following monophyletic clades within crown group caenophidians: Afro-Asian psammophiids (including Mimophis from Madagascar), Elapidae (including hydrophiines but excluding Homoroselaps), Pseudoxyrhophiinae, Colubrinae, Natricinae, Dipsadinae, and Xenodontinae. Homoroselaps is associated with atractaspidids. Our analysis suggests some taxonomic changes within xenodontines, including new taxonomy for Alsophis elegans, Liophis amarali, and further taxonomic changes within Xenodontini and the West Indian radiation of xenodontines. Based on our molecular analysis, we present a revised classification for caenophidians and provide morphological diagnoses for many of the included clades; we also highlight groups where much more work is needed. We name as new two higher taxonomic clades within Caenophidia, one new subfamily within Dipsadidae, and, within Xenodontinae five new tribes, six new genera and two resurrected genera. We synonymize Xenoxybelis and Pseudablabes with Philodryas; Erythrolamprus with Liophis; and Lystrophis and Waglerophis with Xenodon.

Taxonomic studies on the Neotropical Landrevinae with description of new taxa (Orthoptera, Grylloidea, Gryllidae)

The understanding of the subfamily Landrevinae has been modified by different authors since its creation. In the neotropics three genera are known to the present: Odontogryllus Saussure, 1877 (one from México, the others amazonian), Brasilodontus de Mello, 1992 with two species (from Brazilian Atlantic Forest), e Valchica de Mello, 1992 with one species (from Costa Rica). De Mello (1992) erroneously created the tribe Odontogryllini for this cluster of neotropical genera, here suppressed. In the present paper we revise and add new species to Brasilodontus and describe two monotypic genera, Xulavuna n. gen. and Yarrubura, n. gen. An identification key to the genera of neotropical Landrevinae is presented as well as one for the species of Brasilodontus. The male fore wings of Xulavuna adenoptera n. sp. is remarkable regarding its shape and its glandular condition

Unraveling Trichoderma species in attine ant environment: description of three new taxa

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

Notes and new taxa in Acanthoderini (Coleoptera: Cerambycidae: Lamiinae). V. Three new genera and notes on Irundisaua.

Generic characters of Irundisaua Martins & Galileo, 2005 are expanded (antennal formula, width of prosternal process inferior or equal to the diameter of procoxa, protibia enlarged and flattened) and two species are transferred from Acanthoderes Audinet-Serville, 1835: I. forsteri (Tippmann, 1960) comb. nov from Peru and Brazil (Amazonas) and I. ucayalensis (Tippmann,1960) comb. nov from Ecuador, Peru and Brazil (Amazonas).Three new genera are described: (1) Catuana gen. nov., type species, C. spinicornis (Tippmann, 1960) comb. nov, characterized by the mesosternal tubercle; (2) Mundeu gen. nov, type species, M. maculicollis (Bates, 1861) comb. nov, with rounded sides of protorax and expanded protibiae; (3) Urangaua gen. nov, with eyes divided and finelly granulated, length of antenomeres III-IV subequal to V-XI; the genus is proposed of two species: U. analis Melzer, 1935 comb. nov, type species, and U. subanalis (Zajciw,1964) comb. nov. A key to the species of Urangaua is added.

New taxa and new record of Hemilophini (Coleoptera: Cerambycidae: Lamiinae).

New species described and illustrated: Adesmus nigrolineatus sp. nov from Mexico (Oaxaca). From Costa Rica: A, moruna sp. nov. (Heredia); Corcovado bezarki sp. nov. (Guanacaste); Alampyris fuscus sp. nov. (Guanacaste), Cariua gen. nov type species C. sulphurea sp. nov. (Guanacaste). From Bolivia: Phoebemima albomaculata sp. nov. (Cochabamba); Ipepo gen. nov type species I. dilatatus sp. nov. (Santa Cruz). From Brazil: Adesmus facetus sp. nov and Canarana arguta sp. nov. (Rondonia). A new record from Costa Rica of Piruanycha pitilla Galileo & Martins, 2005 is added. The three new species of Adesmus are recognized: A. nigrolineatus by the longitudinal black stripes on elytra; A. moruna by the elytra entirely black; A. facetus by the white belts behind the middle of the elytra and white maculae on apical quarter. Phoebemima albomaculata is characterized by the white macula on the elytral suture. Corcovado bezarki sp. nov is distinguished by the black antennal scape and whitish flagelomeres. Canarana arguta sp. nov has prothorax and urosternites I-IV covered by dense yellowish pubescence. Alampyris fusca sp. nov differs from A. cretaria by the antenomere III longer than scape. Cariua sulphurea sp. nov is distinguished by the urosternites covered by compact white pubescence and Ipepo dilatatus is characterized by the elytra with three carinae.

The new genus Mexicoscylus is described to include: M. rosae sp. nov., type species of the genus, and M. bivittatus (Gahan, 1892), comb. nov. both from Mexico. A key to the species of Mexicoscylus is added. More three species are described: Cotycuara villosa sp. nov., from Costa Rica; Phoebe parvimacula sp. nov., from Bolivia and Adesmus beruri sp. nov., from Brazil (Amazonas). All new species are illustrated.
