The two previously known species of the genus Cantabrogeus (Coleoptera, Leiodidae, Cholevinae, Leptodirini) are redescribed, and three new species are described: Cantabrogeus antimachus n. sp., C. cultellus n. sp. and C. fresnedai n. sp. One of these (C. antimachus n. sp.) is tripliod (3n = 33) and the first known parthenogenetic species of Leiodidae. The relationships between the different taxa are discussed based on external morphological characters and the structure of male and female genitalia, as well as the distribution of the species in the different areas in the Cantabrian mountains (NW Iberia). Analyses of molecular data (fragments of seven mitochondrial and nuclear genes) confirms the monophyly of Cantabrogeus and its sister-group relationship with Fresnedaella, as well as its inclusion within the paraphyletic series Quaestus. The parthenogenetic species (C. antimachus n. sp.) has a derived position within Cantabrogeus, which, according to previous estimates of the molecular rate, probably diversified during the Pliocene-Pleistocene in the Cantabrian karst areas, of a high tectonic complexity. © 2012 Museu de Ciéncies Naturals de Barcelona.

Chorological information of 15 Ibero-Balearic species of the genus Desmestes Linnaeus, 1758 is provided. Data were obtained from the review of 635 specimens housed in the entomological collection of the Natural History Museum of Barcelona. All examined material is listed, and the distributions are discussed taking into account the collection records and bibliographical sources. The distribution areas for most species have been extended. Source

Distribution of Stenostoma rostratum (Fabricius, 1787) in Catalonia is updated. New data were obtained from recent prospections at two natural reserves of the Mediterranean coast, the Espais Naturals del Delta de Llobregat (province of Barcelona) and the Parc Natural de les Illes Medes, Mas-sís del Montgrí i Plana del Baix Ter (province of Girona). The species is found exclusively in sand dunes, ocupping a reduced area in the catalonian coast. Stenostoma rostratum is considered a threatened species in Catalonia, the last records published up to now being obtained 40 years ago. Some remarks about its habitat, ecology and conservation in both protected areas are also provided. © [2012] del artículo pertenece al autor o autores. Source

A new Neotropical species of Trentepohlia (Mongoma) is described from Cuba. This is the first species of the subgenus from the West Indies, whereas the other four Trentepohlia spp. are from the subgenus Paramongoma. Notes on the phenology of this new species are provided. Also, we discuss the transfer of Trentepohlia suberrans Alexander, 1979 to Mongoma and provide a key for the identification of the three species of this subgenus present in the Neotropics. Source

We evaluated damage to commercial crops caused by the monk parakeet, Myiopsitta monachus, in the Baix Llobregat agricultural area (1,024 ha) bordering the city of Barcelona, Spain. Average crop loss was 0.4% for tomatoes, 28% for corn, 9% for red plums, 36% for round plums, 37% for pears, 17% for persimmons, and 7% for quinces. Our data show that the potential damage to crops by monk parakeets in this invaded area is now a reality. As a wait–and–see approach is likely to be a more costly strategy in the long–term, policy makers should assess issues such as the extent of damage, feasibility/cost benefit analysis, and public opinion so as to avoid greater damage and loss in the future. © 2016 Museu de Ciències Naturals de Barcelona.
