It is relatedtoP. assigillata (Börner, 1901)andP. balcánicaCassagnau et Peja, 1978 described from Gennany and Albaniarespectively. The newspecies ischaracterizedby moderate plurichaetosison dorsal sideofthe body, elongated labium, thepresence ofthe male ventral organ and fourteeth on claws. Keywords. Entomology, taxonomy, Collembola, Neanuridae, Pseudachorutella, new species, Poland. 1.
