This species was originally described from the island of Gotland, Sweden (Lundblad 1956), but later on synonymized with L.porosa. Recently Tyukosova et al. (2022) used material from Norway to redescribe L.gibbosa based on morphological and molecular evidence and showed that this species is widely distributed in southern Norway.

The sequenced specimens from Portugal were clustered within BOLD:ACR9744, which, in addition to the specimens from Portugal, includes specimens of L.gibbosa from the Netherlands, Norway, Poland, and Germany, available in BOLD.

As this species has been widely overlooked with other species of L.porosa complex, the full geographical distribution of L.gibbosa cannot be defined without additional research.
