Abstract |
Material recently collected from the Solomon Islands include three species of Acanthaxius Sakai &
de Saint Laurent, 1989, two of which are new to science: A.clevai n.sp.and A.gadaletae n.sp.
and a specimen of A.polyacantha Miyake & Sakai, 1967.Two specimens from New Caledonia are
assigned to A.gadaletae n.sp.The new taxa are readily differentiated from A.polyacantha by their
longer rostrum and the glabrous postcervical region of carapace.A.clevai n.sp.is characterized by
a slender rostrum longer than the eyestalks, with two lateral and a suborbital spine, the gastric
region with a median, submedian and lateral carina, setose pereopods 1 with three and two upper
spines on the propodal palm and dactylus respectively, the telson longer than broad with three teeth
and one spinule on the lateral border.A.gadaletae n.sp.is similar to A.clevai n.sp.but differs by
the gastric region with two submedian carinae, the pereopod 1 with four upper spines both on the
propodal palm and the dactylus, the maxilliped 3 basis with a large lower distal spine (absent in A.
clevai n.sp.) and the abdominal pleura 3–5 with an anterior spinule (absent in A.clevai n.sp.). |
