The main diagnostic characters to distinguish B. payeri from the other species of
Bythocaris are: 1, the dark pigmentation of the eye; 2, the anteriorly rounded scaphocerite;
3, the rostrum, as a rule, not overreaching the base of the cornea of the eye; 4,
the pleura of the first five abdominal segment usually being rounded; 5, the ventrally
sinuous rostrum; 6, the armed meri of the third through fifth pereiopods. These six
characters are always present together. (Sokolov, 2000)
