During a faunistic survey in the Pieniny and Tatra Mountains three species of Echiniscidae new to Poland, including one new to science, were found. Bryodelphax instabilis sp. nov. is characterised by an instable number of ventral plates, deep faceting of the scapular plate, having dorsal plates covered either with pseudopores or pores, and striking sexual dimorphism. Two first records, namely Echiniscus militaris and E. spiniger, are rare taxa of upland-mountain character, which have already been reported from a few European countries since the original description at the beginning of the XXth century. The interspecific appendage length variability and development of pedal plates in the spinulosus group, to which E. spiniger belongs, and their taxonomic importance is discussed. Notes relating to sexual dimorphism within the newly recorded Pseudechiniscus facettalis, are also presented. Echiniscus testudo is reported from the Polish part of the Tatra Mountains for the first time. Succeeding findings confirm the high tardigrade α-diversity in the Polish mountain ranges. An amended key for Polish Heterotardigrada is provided.
在皮耶宁山脉和塔特拉山脉进行动物区系调查期间，发现了三种波兰新记录的棘影熊虫科物种，其中包括一种新的科学物种。不稳定苔藓熊虫（Bryodelphax instabilis sp. nov.）的特征是腹板数量不稳定、肩胛板刻面深、背板覆盖有假孔或孔，以及显著的两性异形。另外两个首次记录，即武装棘影熊虫（Echiniscus militaris）和刺棘影熊虫（E. spiniger），是具有山地特征的稀有分类群，自20世纪初首次描述以来，已在一些欧洲国家被报道过。本文讨论了刺棘影熊虫所属的多刺棘影熊虫组中种间附肢长度变异性和踏板发育情况及其分类学重要性。还介绍了有关新记录的刻面拟棘影熊虫（Pseudechiniscus facettalis）两性异形的相关记录。在塔特拉山脉的波兰部分首次报道了龟甲棘影熊虫（Echiniscus testudo）。后续发现证实了波兰山脉中缓步动物的高α多样性。提供了一份修订后的波兰异缓步纲检索表。
