Occurring on the lower slopes and the Sao Paulo Plateau area, ranging from depths of 991 - 1974 m. Twenty-two individuals of this species were collected, with 41 % of them found in the 5 - 10 cm sediment layer (i. e. up to 50 - 60 x their body length) and 32 % at a depth of 2 - 5 cm.	en	Segadilha, Juliana Lopes, Bird, Graham, Tavares, Marcos (2023): Stenotanais (Crustacea, Tanaidacea) from the Santos Basin: the first described species of the family Akanthophoreidae off the Brazilian coast.
