          Abstract

          Austromonticola gen. n. is proposed for a group of eight New Zealand alpine broad-nosed weevil species, all of which are here described: A. atriarius sp. n. (type locality: Umbrella Mountains, Central Otago), A. caelibatus sp. n. (type locality: Ohau Range, Mackenzie), A. furcatus sp. n. (type locality: Old Man Range, Central Otago), A. inflatus sp. n. (type locality: Hawkdun Range, Central Otago), A. planulatus sp. n. (type locality: St Marys Range, Central Otago), A. postinventus sp. n. (type locality: Kirkliston Range, South Canterbury), A. mataura sp. n. (type locality: Mt Dick, Otago Lakes) and A. rotundus sp. n. (type locality: Old Man Range, Central Otago). All species occur exclusively above 1000 m elevation in the mountains of Central Otago and South Canterbury in the South Island. A phylogeny of the genus, including six outgroups, was inferred from 33 morphological characters. It resolved the genus as monophyletic, and revealed two strongly supported clades within Austromonticola . DNA sequences of four gene regions were obtained from five species. Of these, the 3' end of COI proved to be the most suitable for the identification of specimens. Females of all species have diagnostic secondary sexual structures on the elytra and ventrites. These structures are hypothesised to have evolved to assist with oviposition in and beside cushion plants or by selection for structures to mitigate the costs to females of prolonged mating.

            APE: Analyses of Phylogenetics and Evolution in R language.

            Analysis of Phylogenetics and Evolution (APE) is a package written in the R language for use in molecular evolution and phylogenetics. APE provides both utility functions for reading and writing data and manipulating phylogenetic trees, as well as several advanced methods for phylogenetic and evolutionary analysis (e.g. comparative and population genetic methods). APE takes advantage of the many R functions for statistics and graphics, and also provides a flexible framework for developing and implementing further statistical methods for the analysis of evolutionary processes. The program is free and available from the official R package archive at http://cran.r-project.org/src/contrib/PACKAGES.html#ape. APE is licensed under the GNU General Public License.

              Predation risk as a cost of reproduction.

               C Magnhagen (1991)
              Predation risk as a cost of reproduction in animals has recently received increased empirical and theoretical attention. Higher risk may be associated with all stages of reproduction. Examples of evolutionary responses to this increased risk include habitat choice, duration and timing of display and copulation, changes in brightness of breeding coloration, and changes in life history traits such as age of reproduction and reproductive effort.
