The holotype of Octopus schultzei (Hoyle, 1910) was examined, to verify its taxonomic status. The holotype, a male and the only specimen known, possesses unusual characters not referred to in the original description nor in subsequent reports. Most striking are the arm tips, all of which, except the hectocotylus (right third arm), have a mass of long, closely packed finger-like processes instead of suckers. The hectocotylized portion of right arm III is very small, uniform and spongy in structure; the end organ lacks a longitudinal depression and cross-striations; a calamus is absent. These and other characters confirm the specific validity of O. schultzei and readily distinguish it from all other known species of Octopus. The systematic significance of these and other unusual characters supports the establishment of a new genus, Aphrodoctopus.
