Anaticapitula clauda, from Dumitrica & Zügel (2003).

Belongs within: Nassellaria.
Contains: Napora.

The Lychnocanioidea are a group of radiolarians known from the Triassic to the present (Afanasieva et al. 2005).

Characters (from Afanasieva et al. 2005): Two to five (more often three) segments. Cephalis medium sized, theoperid or archipilid. Cephalis always not more than one third of entire test. Strong external tripod formed by spines D and 2L, sometimes tetrapod.
