The behaviour and development of Elasmosoma sp., near pergandei Ashm. (Neoneurinae: Braconidae: Hymenoptera), a parasite of the ant, Formica obscuriventris clivia Creighton, was studied in a coastal sand dune habitat in central Oregon over a 2-year period. Female wasps oviposited into the abdomen of major worker ants after alighting briefly on the host. Embryonic development of the wasp occurred inside the serosal membrane or trophamnion of the egg in the abdomen of the ant host. First instar wasp larvae possessed a large head capsule with falcate mandibles, 11 ventral body lobes, an elongate tail and a dorsally located anus. Second instar larvae were unspecialized and lacked the large head capsule, elongate tail and paired ventral body lobes. Third instar larvae were hymenopteriform with a distinct head capsule. Cocoon formation and adult emergence is described. Observations on the percentage parasitism and altered behaviour of parasitized ants are presented. The association between neoneurine wasps and ants is a well-balanced system that has been in existence for at least 40 million years.

The genus Carebara is revised for the Malagasy region, and based on the examination of over 10,000 specimens, twenty-three species are recognized. Twenty one of these are described as new (C.bara sp. n., C.berivelo sp. n., C.betsi sp. n., C.creolei sp. n., C.demeter sp. n., C.dota sp. n., C.hainteny sp. n., C.hiragasy sp. n., C.jajoby sp. n., C.kabosy sp. n., C.lova sp. n., C.mahafaly sp. n., C.malagasy sp. n., C.omasi sp. n., C.placida sp. n., C.raberi sp. n., C.salegi sp. n., C.sampi sp. n., C.tana sp. n., C.tanana sp. n., C.vazimba sp. n.), and two are redescribed, C.grandidieri Forel (= C.voeltzkowi Forel n. syn.) and C.nosindambo Forel. A lectotype is designated for C.nosindambo. C.creolei sp. n. is known only from Mauritius and Seychelles, C.grandidieri Forel is distributed in Comoros, Madagascar and Mayotte, and the other twenty-one species are endemic to Madagascar. Most of the Carebara species recorded in this work are endemic to a specific habitat (ecoregion), but some of them (C.bara sp. n., C.grandidieri Forel, C.jajoby sp. n., C.kabosy sp. n., and C.nosindambo Forel) are widespread within Madagascar across all major habitats. The worker caste of Carebara can be differentiated from other genera in the Myrmicinae subfamily by the presence of the following combination of characters: antennae of eight to eleven segments, with a two-segmented club; anterior clypeal margin without central isolated seta (rarely present in some species or specimens), and usually with four distinct setae; mandibles with four to seven teeth (except in one species from Ghana - C.crigensis with three teeth); and palp formula 2,2 or 1,2. We report that almost all Carebara species found in the Malagasy region have intermediates (distinct forms) in the major worker subcaste, with the largest major workers showing remnants of queen flight sclerites and ocelli. The widespread presence of intermediates in the major worker subcaste expands the morphological boundaries of Carebara. We present an overview of the natural history of Carebara in the Malagasy region, an illustrated key for the identification of the known Malagasy species of Carebara, as well as high-resolution images and distribution maps. Unique identifiers are used for all specimens studied, including type material, and the raw data that forms the basis of this study are available on www.antweb.org (open access).

AbstractIn August, September and October 1933 Cuban sugar workers seized several dozen mills and estates and, in a number of cases, inaugurated soviets. This major worker uprising coincided with the collapse of the regime of Gerardo Machado and the early stages of the reformist administration of Grau San Martín. An examination of the roots of labour organisation among sugar workers and of the dynamic of the insurgency reveals the strengths and the limitations of the role played by the Cuban Communist Party. The collapse of the institutional and coercive structures of the state apparatus greatly facilitated the worker actions.
