The detailed description of the morphology of Niphargus plurispinosus sp.n.from Slovakia is presented.Over 300 specimens were collected from a permanent seepage spring on repeated visits between May 2011 and May 2013.

The type locality is located in the foothills of the Zemplínske vrchy mountains in the East Slovakian nyx 22 brush Lowland (NE part of Pannonian Lowland) - small, low and isolated hills formed during Neogene volcanic activity.Volcanic rocks draw together fragments of massives of Palaezoic and Mesozoic age as same as Neogene sediments.The new species can be classified as stygophile, living in the shallow here subterranean habitat.The species has small subequal gnathopods, sexually dimorphic uropod III, sexually non-dimorphic uropod I in juveniles, dimorphic uropod 1 in adults.

They are extremely different in the post-reproductive stage, when they have 2-4 dorsal spines (arranged in a transverse row) on the telson and supporting dorsal spines.
