"TYPE-SPECIES—Igene walleni.
ETYMOLOGY—The genus is named after I. Eugene Wallen. Gender: masculine.
This new genus is monotypic.
DIAGNOSIS OF GENUS—Carapace without ribs.
Second antenna: Endopodite of female 2-jointed.
Maxilla: With 3 distinct endites.
Fifth limb: 2nd exopodite joint with large quadrate tooth.
Sixth limb: End joint with relatively few bristles.
Seventh limb: Absent on male.
Furca: No secondary claws between primary claws.
Rod-shaped organ: Short, conical.
COMPARISONS—This new genus is based mainly on the short, conical rod-shaped organ. It is found in no other genera of the Philomedidae. Tetragonondon rhabdion (Kornicker, 1970a:36) has a short rod-shaped organ, but it is cylindrical.
DISTRIBUTION—The type-species was collected in the Pacific Quadrant within the Antarctic Convergence at depths of from 3386 to 3817 m and off the Pacific coast of Chile at a depth of 4303 m. The northernmost locality is at 37°57'S, 75°08'W; the southernmost locality is at 59°57'S, 136°39'W." (Kornicker 1975, p.367-368)
