Two new species, Dorvillea bermudensis sp.n. and D. albomaculata sp.n., with obligate asexual reproduction are described. Both are closely related to sexually reproducing members of the same genus. The new species undergo repeated fission of the architomy type, with the rate of regeneration and subsequent production of segments being positively correlated with the energy content of the fragments. Regeneration and reproductive potentials vary between head and tail fragments with tail lineages producing higher rates than head lineages. Both species are very tolerant of starvation which may cause considerable degrowth and initiation of dispersal behavior.
