(Hymenoptera, Formicidae) Author Seifert, Bernhard text Soil Organisms 2020 2020-05-26 92 1 15 86 http://dx.doi.org/10.25674/so92iss1pp15 journal article 10.25674/so92iss1pp15 2509-9523 10832216 Lasius transylvanicus Rözsler 1943 Lasius transylvanica Rözsler 1943 Rözsler claimed to have made intensive observations of nest construction and behavior of this ant in the floodplain of the Nyarad river / Romania . The morphological description reports a dense and erect scape pilosity as in Lasius niger in combination with complete absence of setae on legs as found in Lasius alienus . I have never seen such an ant in thousands of Palaearctic Lasius samples. The description of behavior also indicates involvement of phantasy, invention or cognitive failure.
