Seven
species are tentatively accepted today:
L. superlata (the
type species),
L. persephone and
L. protogonia from the Burgess Shale,
L. illecebrosa and
L. obesa from the Chengjiang biota, ''
L. robisoni from Kaili, and
L.?
hanceyi from the
Spence Shale.
L. superlata and
L. persephone may however be examples of
sexual dimorphism. == Distribution ==
