Two new squids from the western Indian Ocean acquired during the Netherlands Indian Ocean Programme (NIOP) expeditions in 1992-1993 are described. The species new to science is Chiroteuthis (C.) spoeli, member of the subgenus Chiroteuthis s.str., which differs from the type species Chiroteuthis (C.) joubini chiefly in the enlarged suckers on arm II and III and the tentacular sucker morphology. The new subspecies is assigned to the subgenus Chirothauma in the species Chiroteuthis (C.) picteti and defined as Chiroteuthis (C.) picteti somaliensis, and is characterized by the sharp teeth in the arms. The genus Chiroteuthis, as now defined, consists of 2 subgenera, 7 species and 4 subspecies.

The ultrastructure of the sucker surface is described and its systematic value for mastigoteuthid squids, which bear minute suckers, is considered. An introduction to sucker terms is given and a redefinition of these terms is attempted. Using scanning electron microscopic data, two genera and four subgenera of Mastigoteuthidae from the Northwest Pacific are distinguished. The presence of “cushions” in the sucker is discussed and considered as a character important for understanding adaptations of cephalopods to the deep-sea.

Cephalopods of the Red Sea, Gulf of Aden and the Western Indian ocean off Somalia are studied. A preliminary annotated list is presented. This study was based on the examination of 381 specimens captured with a Rectangular Midwater Trawl (RMT8) during three cruises of the Netherlands Indian Ocean Programme. The taxa identified represent: 22 families, 35 genera and 56 species. Two species new to science are found. Systematic position and taxonomic re-evaluation in the Chiroteuthidae, Mastigoteuthidae and Octopodidae is briefly discussed. The present collections represent a valuable contribution to the species composition from the Western Indian Ocean and to cephalopod juvenile morphology.

Seven species of bathypelagic squids from the West Indian Ocean are described. Two species from the chiroteuthid lineage are recorded: Pianktoteuthis sp. and Chiroteuthis mega. The family Mastigoteuthidae is divided in two genera: Idioteuthis and Mastigoteuthis. As members of the former are Idioteuthis danae (=Echinoteuthis danae) and two species new to science, and for the latter Mastigoteuthis glaukopis and Mastigoteuthis grimaldii. The mastigoteuthid lineage is defined by: 1) short neck and brachial pillar; 2) whip-like tentacle; 3) ovate pseudoconus in cross section view, and 4) arm formula: IV>II>III≥I. The family Mastigoteuthidae as now defined consist of seventeen species.
