Increasing urbanization of many regions of the world has resulted in the decline of suitable habitat for wild flora and fauna. Green roofs have been suggested as a potential avenue to provide patches of good-quality habitat in highly developed regions. In this study, we surveyed green roofs for bee diversity and abundance to determine their potential as quality habitats in an urban area for these important pollinators. By comparing various biodiversity measures between green roofs and ground-level sites, we show that green roofs provide habitat to many bee species. Implications for pollinator conservation and urban agricultural production are discussed.

The southern South American subgenus Chilioediscelis Toro and Moldenke is revised. The males and females of three new species, C. mirzamalae Willis & Packer, C. sardonyx Willis & Packer and C. penai Willis & Packer, are described. A key to species, distribution map and results of a phylogenetic analysis of the subgenus are provided. All character states used in phylogenetic analysis are either illustrated or references to figures of them are given.

The purpose of this application is to conserve the specific name of Coccyzus euleri Cabanis, 1873, long established in general use for the South American pearlybreasted cuckoo. The name is made invalid by the senior subjective synonym C.julieni Lawrence, [1864].
