Abstract

Tantulocaridans (Class Tantulocarida) are primarily known to parasitize copepods, tanaidaceans, and isopods while only single species have been recorded from amphipod, ostracod, and cumacean hosts. Examination of a collection of deep-water peracarids from the Campos Basin off northeastern Brazil resulted in the discovery of a tantulus larva attached to a juvenile Styloptocuma angustatum (Jones, 1984) (Cumacea, Nannastacidae), representing a new species and only the fifth record for this host group. The new species is provisionally assigned to the genus AphotocentorHuys, 1991 (Cumoniscidae) based on the proximally dilated terminal caudal ramus setae, the conspicuous polygonal surface ornamentation on the thoracic somites, the spinous processes around the posterior border of the abdomen, the dorsal abdominal surface pattern consisting of four continuous transverse lamellae, and the spinular ornamentation on the protopods of legs 2–6. The tantulus of A. kolbasovisp. nov. is characteriz...
