摘要

描述并举例说明了来自乌兹别克斯坦的一种新的缓步动物Richtersius mazepi sp.nov。与之前描述的所有三种同类进行比较，揭示了蛋饰的一系列独特形态特征，这使得新物种与其他物种明显不同。独特的特征如下：（i）在蛋过程的底部周围存在折射光的点或孔和增厚的冠；（ii）在所述过程之间在蛋表面上存在黑点；（iii）在卵突的近端部分的壁中被视为光折射点的迷宫层；和（iv）卵突，包括宽圆顶形近端部分和细长远端部分。本研究中发现的新物种构成了Richtersius Pilato和Binda属中第四个正式描述的物种，1989年。还讨论了基于形态学数据的经典分类学描述的使用问题。

New Species of the Genus Richtersius Pilato & Binda, 1989 (Tardigrada: Eutardigrada: Richtersiusidae) from Uzbekistan

A new tardigrade species from the family Richtersiusidae, Richtersius mazepi sp. nov., from Uzbekistan, is described and illustrated. A comparison to all three of the previously described congeners revealed a unique set of morphological characteristics of the egg ornaments, which makes the new species clearly distinct from the others. The unique characteristics are as follows: ( i) the presence of light-refracting dots or pores and a crown of thickenings around the base of the egg processes; ( ii) the presence of dark dots on the egg surface between the processes; ( iii) a labyrinthine layer seen as light-refracting dots in the wall of the proximal portion of the egg processes; and ( iv) egg processes comprised of a wide dome-shaped proximal portion and an elongated slender distal portion. The new species discovered in this study constitutes the fourth formally described species within the genus Richtersius Pilato & Binda, 1989. The issue concerning the use of a classical taxonomic description based on morphological data is also discussed.
