Crustacea Leucothoe oxumae sp. nov. Stenothoe ogumi sp. nov. South Atlantic Ocean coral reef taxonomic key


Two new species of amphipods associated with the bioinvasive coral Tubastraea coccinea from Todos-os-Santos Bay are described. The bioinvasive sun coral is known for competing with native coral species, which shelter a big diversity of associated fauna, especially amphipods. Leucothoe oxumae sp. nov. shows acute rostrum, antenna 1 about 1/4 of body length; gnathopod 1 carpochelate, propodus with 5 anterodistal robust setae; gnathopod 2 propodus fusiform, slightly serrated on palmar margin and posterodistal corner of epimeral plate 3 produced and rounded. Stenothoe ogumi sp. nov. is unique by showing a pronounced and developed maxilliped inner plate, gnathopod 2 propodus palm pointed with slightly undulated processes and two developed ones near hinge of dactylus and palmar margin beset with dense fringe of long setae. Updated taxonomic key to Leucothoe and Stenothoe species from Brazil are provided.
