Pederin belongs to a group of antitumor compounds found in terrestrial beetles and marine sponges. It is used by apparently all members of the rove beetle genera Paederus and Paederidus as a chemical defense against predators. However, a recent analysis of the putative pederin biosynthesis (ped) gene cluster strongly suggests that pederin is produced by bacterial symbionts. We have sequenced an...

High altitude ecosystems are often home to endemic species that have evolved in isolation from their low elevation counterparts. In many cases, especially insects, such mountain endemics apterous (due reduced ability fly and disperse). most so far, these genetically differentiated lowland sister or populations. During an excursion Central Spain, we encountered two strikingly different morphotyp...

It is well understood that agricultural expansion and associated loss of semi-natural habitat in the landscape are major drivers for marked decline biodiversity. While conserving remaining patches essential to reverse ongoing biodiversity declines, increasing focus has also been put on diversifying cropland itself by crop diversity as a measure compositional heterogeneity, reducing field sizes ...

Abstract The omaliine rove beetle genus Phlaeopterus Motschulsky, 1853 contains 22 species. is distributed across northwestern North America and eastern Asia. These beetles occur primarily along the edges of alpine snowfields streams, habitats that are particularly sensitive to impacts climate change. Two species have not been collected since 1979 1984, one which, bakerensis Mullen Campbell, 20...

The life history characteristics of the rove beetle Paederus fuscipes Curtis were studied under laboratory conditions using three field strains from Malaysia: Desa Wawasan (DW), Sri Pinang (SP), and Ampang Jajar (AJ). The total development time of immature stages differed significantly among the three strains, especially between DW (17.43 +/- 0.16 d), SP (18.60 +/- 0.19 d), and AJ (18.68 +/- 0....

The New Zealand fauna of Hyperomma Fauvel, 1878, a rove beetle genus occurring only in Australia and New Zealand, is revised. Twenty-five Hyperomma species are reported from New Zealand, of which the following 17 new species are described here: Hyperomma montanum Schomann, n. sp., H. longicorne Schomann, n. sp., H. orientale Schomann, n. sp., H. bicoloripes Schomann, n. sp., H. johnnunni Schoma...

The genus Antimerus Fauvel, 1878, endemic to eastern Australia and Tasmania and a phylogenetically enigmatic member of the large rove beetle tribe Staphylinini, is revised. The genus and each of its four previously known species are redescribed, and a lectotype is designated for Antimerus punctipennis Lea, 1906. Five species are described as new: Antimerus metallicussp. n., Antimerus jamesrodma...
