ResumoSpiders of the genus Uloborus (Uloboridae) characteristically spin horizontal orb-webs with a sticky spiral of cribellar silk.We describe here the webs of U. conus, U. albolineatus, U. bispiralis, U. #2072, U. trilineatus, and Conifaberparvus.whichare modifications of this basic uloborid orb-web form and include cones composed of regular arrays of threads beneath the orbs' lower faces.The web building and prey capture behaviors of U. conus (observations of YDL) are also described, and descriptions of Conifaber parvus new genus, new species and the new species U. conus, U. albolineatus, and U. bispiralis are provided (by BDO). STUDY SITES AND METHODSUloborus conus was found at three localities in Papua New Guinea: 1) in lowland wet forest, Gogol Forest Reserve near Madang, Madang Province, 2) in a Pandanus swamp (freshwater) and a mangrove swamp (brackish) at Buso, Morobe Province, and 3) in the understory of klinki pine (Araucaria hunsteinii) plantations at 1200 m elevation in McAdam Memorial Park near Wau, Morobe Province.Webs were built about 0.5 to 2.0 m above the ground in gaps formed by the uppermost, generally vertical branches of small shrubs and saplings.They were always found in humid, shaded
