Abstract:
Two new species of Gracilariopsis from the Indian
Ocean are proposed—Gracilariopsis (Gp.) mclachlanii
Buriyo, Bellorin et M. C. Oliveira sp. nov. from
Tanzania and Gracilariopsis persica Bellorin, Sohrabipour
et E. C. Oliveira sp. nov. from Iran—based on
morphology and DNA sequence data (rbcL gene and
SSU rDNA). Both species fit the typical features of
Gracilariopsis: axes cylindrical throughout, freely
and loosely ramified up to four orders, with an
abrupt transition in cell size from medulla to cortex,
cystocarps lacking tubular nutritive cells and superficial
spermatangia. Nucleotide sequence comparisons
of rbcL and SSU rDNA placed both species
into the Gracilariopsis clade as distinct species from
all the accepted species for this genus, forming a
deeply divergent lineage together with some species
from the Pacific. The new species are very difficult
to distinguish on morphological grounds from other
species of Gracilariopsis, stressing the importance of
homologous molecular marker comparisons for the
species recognition in this character-poor genus.
