  Study on flora and Auchenorrhyncha biocenoses (Insecta Hemiptera) in moist areas considered restricted relics of the ancient Lacus Velinus in the provinces of  Terni and Rieti (Umbria and Latium, Italy)

  ABSTRACT
  A research on vascular plants and Auchenorrhyncha biocenoses in moist areas of the provinces of Terni (Umbria) and Rieti (Latium) was conducted from 1999 to 2015. Prevalently four areas were studied: Lago di Piediluco, Lago di Ventina, Lago Lungo and Lago Ripasottile. 267 taxa of vascular plants are recorded on the whole. Species of particular interest are Butomus umbellatus, Carex acutiformis, C. elata, C. pseudocyperus, C. paniculata, Cladium mariscus, Epipactis palustris, Frangula alnus, Glyceria maxima, Hydrocharis morsus-ranae, Nuphar lutea, Oenanthe aquatica, Orchis incarnata, Ranunculus lingua, Rorippa amphibia, Rumex hydrolapathum, Scutellaria galericulata and Viburnum opulus, all included in the Regional Red Lists of Italian Plants of Umbria and Latium. 162 Auchenorrhyncha species were collected. Four species (Cixius remotus, Kelisia punctulum, Anakelisia fasciata and Megamelodes lequesnei) are recorded for the first time for Italy, five (Kelisia praecox, Struebingianella lugubrina, Chloriona smaragdula, Hishimonus cf. hamatus and Metalimnus formosus) are new records for the Apennine Peninsula (“S” in the checklist of the Italian fauna). For some species of special interest, their ecology, life cycle and distribution are discussed. 60 taxa are strictly correlated with moist habitats. The investigated areas are of high relevance for nature conservation as they constitute small relics of the ancient Lacus Velinus, where several stenotopic Auchenorrhyncha species occur, associated particularly with moist vegetation.
