epipelagic.
After Vives & Shmeleva (2010, p.84), the difference between this species and O. vivida are the rostrum's curve and because O. vivida is more slender and of lesser size. Urosome length similar to O. vivida but more narrow and long.. Prosome length similar of urosome (contrary to O. vivida). The cephalosome width is different : more broad in O. vivida than in O. pseudovivida. Also, A1 are longer, reaching the 3rd abdominal segment. Md well developed with 3 setae on the endopod (contrary 5 in O. vivida). Mx1, Mx2 and Mxp similar for the two species.. Genital segment 2 times the length of the following abdominal segments, and swollen in the proximal part. Anal segment shorter than the preceding. Caudal rami 3 times longer than width.
