摘要

一份来自马达加斯加琥珀山附近低地雨林生物多样性热点地区的苔藓样本，发现了两种棘藓。Schultze, 1840种，其中1种为新种。11 .与棘棘属的其他成员有关系，但与它们的不同之处在于背板的高度复杂的结构，甲的复杂增厚部分形成了装饰图案。在新分类单元的种内变异性恢复的背景下，讨论了口内暗环作为分类特征的有效性。此外，岛上还首次报道了罕见的非洲锥虫(murray, 1907)。

New Echiniscidae (Heterotardigrada) from Amber Mountain (Northern Madagascar)

A moss sample from the local biodiversity hotspot in lowland rainforest in the vicinity of Amber Mountain, Madagascar, yielded the discovery of twoEchiniscusC.A.S. Schultze, 1840 species, of which one is new to science.Echiniscussuccineussp. nov.is related to other members of thespinulosusgroup, but differs from them by the highly complicated structure of the dorsal plates, with intricately thickened parts of the armour forming ornamented pattern. The validity of the intraporal dark rings as a taxonomic trait is discussed in the context of the recovered intraspecific variability for the new taxon. Besides, rareEchiniscusafricanusMurray, 1907 is reported for the first time from the island.
