Lasius emarginatus (Olivier, 1791:494)
This is a Central and South European species that occurs in Poland, and the Channel Islands. It is distinguished in the worker caste by the distinctly red alitrunk, more sparse, oblique appendage hairs and relatively longer antennal scapes. The queen has the mesoscutum reddish and distinctly flattened. The male has the mesopleurae in part testaceous yellow, sparse scape hairs and a more sculptured frontal triangle than L. niger.
