摘要: Five genetically distinct and reproductively isolated species have been detected previously within the morphospecies Pseudoterranova decipiens from Arctic-Boreal, Boreal Antarctic. Morphological analysis was carried out on male specimens identified by genetic (allozyme) markers, allowing detection of significant differences at a number characters between two members P. complex, namely A B. On basis such differences, nomenclatural designation for is discussed. The names krabbei n. sp. (sensu stricto) are proposed B, respectively. differentiation shown using multivariate analysis. Allozyme diagnostic keys routine identification four (s.s.), krabbei, bulbosa azarasi, irrespective sex life-history stage, provided.
