Up to now 259species are described for the oriental fauna. With very few exceptions, thedescriptions by preceding authors have been based on external charactersonly, and this group was up to now not revised. On base of 18,000 museumspecimens and further newly collected material, in particular from Malaysia, arevision was started two years ago. Intensive studies on genital structures hasresulted several taxonomic changes and new phylogenetical relationships. Anexample is Ochralea, a genus that been synonymised with Monolepta since1924, but could be found as distinct group of galerucines and restricted tothe Oriental Region. As well as the genus Arcastes that possess very peculiargenitalic structures, is an endemic to South-East Asia. The studies on Monoleptaare ongoing, and additional to the high number of described species many newtaxa could be found. Next to descriptions of the taxa, including illustrationsof external and genital characters, geographical distribution are compliedin maps, and identification keys are provided. The primary type specimensare photographed, and an electronic type catalogue will be available by theinternet.1Organismische Botanik, Tübingen, DE, ingeborg.haug@uni-tuebingen.deMycorrhizas of Cedrela sp. were sampled on different sites in the Rio San Franciscovalley in Southern Ecuador. Planted seven years old seedlings were sampled onthree different successional stages of abandoned pastures and in a gap of apine forest; mycorrhizas of planted and naturally regenerated seedlings werecollected in the pristine forest. Old growth forest trees were sampled on thepasture site and in the pristine forest. The arbuscular mycorrhizal communitiesat the different sites was investigated with molecular methods and comparedwith former results, which showed different communities in reforestation plotsand pristine forest.Wednesday WEDNESDAY 16:00 | FOYER | FoyergtöSociety for Tropical Ecology | Gesellschaft für Tropenökologie e.V.
