Hill et
al. (2008: 142) follow Crandall-Stotler & Stotler
(2007) in separating M. flotoviana from M. hibernica s. str., the latter
being a montane species in the British
Isles.
Apparently long extinct in Cornwall, where also
recorded in the nineteenth century between Loggans Mill and
Treeve, Phillack, and destroyed by drainage (Curnow 1882,
Paton 1969a: 693).
