          Abstract

          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 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 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.

              Toward a unified taxonomy of Niphargus (Crustacea: Amphipoda): a review of morphological variability

              Niphargus is the largest genus of freshwater amphipods, burdened with problematic and largely incomplete taxonomy. This paper is an overview of the morphological characters relevant for niphargid taxonomy, and is conceived as an early step toward a unified taxonomy in the emerging era of cyber-taxonomy. The core element is a taxonomic on-line revision system based on a continuously updated, peer-reviewed and freely accessible morpho-databases (see for example http:// niphargus.info/) that would provide a source of data necessary for comparisons of taxa, generation of species descriptions, and testing phylogenetic hypotheses. In Niphargus, the coding of morphological variability is not straightforward. Several characters are continuous, polymorphic, or subject to allometric growth. We here present a detailed overview of published and new characters together with their variability levels, and describe how the characters are measured and quantified.
