Abstract

Abstract One hundred seventy-four water bear specimens and 16 eggs (Phylum Tardigrada) were collected from mosses and lichens in South Carolina, representing eight genera and 12 species. Some species could only be identified to species group. Nine species or species groups were new records for South Carolina and two were new for the United States. Echiniscus danieli sp. nov. is described from moss and lichen collected from trees on the campus of the University of South Carolina, Columbia, South Carolina, southeastern U.S.A. The species belongs to the Echiniscus bigranulatus group; its dorsal plate cuticle structure consists of true pores, pillars, and granulation. It differs from other species in the group in lacking basal spurs on any of its claws and in the weak development of dentate collars on the fourth legs (i.e., dentate collar absent, or present with few or no teeth). The bigranulatus group has been considered Neotropical and Antarctic in distribution. The presence of Echiniscus danieli sp. nov. in Nearctic North America therefore expands its confirmed geographical range.

美国东南部南卡罗来纳州的新水熊记录（Phylum Tardigrada），描述了danieli Echinicus sp.nov

摘要从南卡罗来纳州的苔藓和地衣中采集了174个水熊标本和16个蛋（Phylum Tardigrada），代表8属12种。一些物种只能被鉴定为物种群。9个物种或物种群是南卡罗来纳州的新记录，2个是美国的新记录。danieli Echinicus sp.nov.是从美国东南部南卡罗来纳州哥伦比亚市南卡罗来纳大学校园内树木上采集的苔藓和地衣中描述的；其背板角质层结构由真孔、柱状物和肉芽组成。它与该群其他物种的不同之处在于，它的任何爪子上都缺乏基部刺，第四条腿上的齿状项圈发育较弱（即，齿状项圈缺失，或存在，很少或没有牙齿）。比格拉努拉图斯群在分布上被认为是新热带和南极。因此，在近北美洲出现的丹氏棘皮蛙扩大了其已确认的地理范围。
