Introduction

A. hoylei is the type species of the genus. This species was first described from, apparently, the Mascarene Islands (Pfeffer, 1912), western Indian Ocean, but additional records are scarce.

Characteristics

  1. Tentacle clubs
    1. Two rows of Different-sized hooks on manus.
    2. Carpal flap absent(?); aboral keel long, narrow(?).

  2. Arms
    1. Arms IV are modelate in lenght; ALI IV = ca.75.
    2. Arms with 19 - 21 hooks and distal suckers.

  3. Hectocotylus
    1. Hectocotylus is not known.

  4. Integumental Photophores
    1. Ventral mantle and head with scattered arrangement of integumental organs.

Comments

Taxonomic status of this species is unclear. Details of club characters are uncertain because the tentacle of the type specimen was damaged. Some previous records of this species from the Pacific and Atlantic are questionable.

Distribution

Geographical Distribution

This species is possibly only from the western Indian Ocean.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
