DONG Dong, LI Xinzheng. Two new species of the genus
DONG Dong, LI Xinzheng. Two new species of the genus
The genus
Munidopsis
has high biodiversity in seamount habitats. In this study
two new
Munidopsis
species
Munidopsis ahyongi
sp. nov. and
Munidopsis carolinensis
sp. nov. from the Caroline Ridge in the tropical western Pacific Ocean were described.
M. ahyongi
sp. nov. is very similar to a group of species in the
M. serricornis
complex
but can be readily distinguished from the related species in having the oblique posterior orbital margins
2 spines on the lateral carapace margin
and a relatively longer rostral median spine.
M. carolinensis
sp. nov. is different from two related species primarily in having oblique frontal margins
blunt outer orbital angles
straight lateral margins of the rostrum
scale-like rugae on sternites 5-7
and less spinose pereopod 1 (chelipeds
P1) merus and carpus. Aside from the morphological comparisons
DNA barcode analysis and phylogenetic analysis based on the cytochrome c oxidase subunit I gene (COI) were employed for the identification of these new species.
