Xipholeptos is a genus of squid in the family Idiosepiidae. It is monotypic, being represented by the single species Xipholeptos notoides, commonly known as the southern pygmy squid. [4] The species was originally classified as Idiosepius notoides. The southern pygmy squid is native to the southwestern Pacific Ocean, off southern and eastern Australia. It inhabits shallow, inshore waters. [5] It has been recorded off the coasts of New South Wales, South Australia, Tasmania and Victoria. [1]

Females grow to 25 mm in mantle length, while males are not known to exceed 15.8 mm in mantle length. [5] This species occurs in beds of seagrass in bays and inlets where it feeds during the night on small crustaceans such as shrimp. In the daytime they remain hidden within the seagrass, adhering to the leaves of the seagrass using a glue excreted by a gland on the dorsal surface of the body. The females attach the eggs onto seagrass blades, most typically species of the genera Heterozostera and Zostera . There is thought to be a pelagic stage during this species' development. [1]

The type-specimen was collected off Goolwa, South Australia, Australia, and is held at the South Australian Museum in Adelaide. [6]

Iridoteuthis iris is a species of bobtail squid native to the northern central Pacific Ocean; it occurs near the Hawaiian Islands off the southeast and northwest Hancock, Colahan, and Kammu seamounts.

Idiosepius minimus is a species of bobtail squid native to the "coast of Africa" where it occurs in shallow, inshore waters. Specimens collected under the junior synonyms I. biserialis and I. macrocheir were described from Mozambique. Since the further collecting effort off Mozambique has seen additional specimens gained. As a result it has been inferred that this species has a relatively restricted distribution since Idiosepius has not been recorded elsewhere in Africa.
