Oberea fuscipennis (Chevrolat, 1852) species group is revised based on morphology and DNA barcode data. Oberea di-versipes Pic, 1919 and O. infratestacea Pic, 1936 are restored from synonymy. The following two new synonymies are proposed: Oberea fuscipennis ssp. fairmairei Breuning, 1962 = Oberea diversipes Pic, 1919; and Oberea hanoiensis Pic, 1923 = O. fuscipennis (Chevrolat, 1852).

Environmental Science and Pollution Research
Two examples of the creation of naturalized areas in the littoral zone of the Three Gorges Reservoir in the urban core of Chongqing City, China, are described. The areas were created for the purpose of restoring ecological functions and services. Plants were selected based on surveys of natural wetland vegetation in the region, and experiments were conducted to discover the capacity of species of interest to survive the sometimes extreme hydrological regimes at the sites. Novel methods were developed to stabilize the plants against the rigors of extreme summer floods and constant swash, notably zigzag berms of rocks wrapped in iron mesh. The areas include native reeds, grasses, shrubs, and trees. Plant communities in the areas are zoned according to flooding stress, and their structure is less stable at lower elevations that are subjected to greater stress. The tall grass Saccharum spontaneum (widespread in Southern Asia) and the tree Pterocarya stenoptera (native to Southwest China) are notable for their utility at these sites in the center of a large city. Communities of tall reeds and grasses have become so dense and stable that they now provide the ecosystem services of capturing river sediments and resisting erosion of the river banks. It is recommended that extensive greening of the riparian zones in urban areas of the Three Gorges Reservoir be conducted for the purpose of providing ecosystem services, based in part on the experiences described here. © 2015, Springer-Verlag Berlin Heidelberg.
