Introduction

The nototanaidids are concentrated in southern hemisphere shelf environments. In all, four genera are known (Bird & Larsen 2009). Sieg (1973) described the family first in his doctoral thesis and formally later (1976). He (1984) added the monotypic Nesotanaidinae by excluding it from the Anarthruridae. There is one species known from Australia.

Diagnosis

With or without eyes. Pleon with 5 pleonites. Antenna 1 3– or 4–articled. Antenna 2 6–articled. Labium consisting of outer and inner lobe, without terminal palp. Epignath falciform. Maxilliped without coxae, bases medially fused. Dactylus and terminal spine of pereopods 4–6 fused to a slender claw. Pleopodal setation reduced to some degree. Uropods biramous, endopod 2–articled, exopod 1– or 2–articled. Marsupium formed by 4 pairs of sheet-like oostegites. Sexual dimorphism well developed, affecting antenna 1, cheliped and body shape; but males never developed as "swimming males".
