bourdonis in that the frontal lamina of its head is not demarcated, its body is more rounded, it has dorsally visible coxal plates on more pereomeres, its pleopodal endopodites are larger than its exopodites, and its uropods touch each other medially.
The pleopods are similar to those of the type, their exopodites extending considerably beyond the margins of the pleomeres, the subcircular endopodites not covering the central region of the dorsal surface of the pleon.
Pleon of five incompletely separated pleomeres, first four bearing very slender biramous pleopods, their endopodites much smaller.
Five pairs of biramous pleopods nearly symmetrical on opposite sides of body, endopodites of first three pairs greatly expanded into large subrectangular fleshy lobes extending far to sides, other exopodites and all endopodites much reduced and mostly extending posteriorly somewhat beyond margins of lateral plates; pleopods covering all but small medioanterior region of pleon ventrally.
