Taxonomy:

Citation: Cruciplacolithus filigranus Mai, 2001
Rank: Species
Synonyms:

Catostaura filigrana (Mai 2001) Aubry in Aubry & Bord (2009). The genus Catostaura was proposed for this species on the basis of its  unusual central structure and the way in which lower tube cycle protrudes distally.    

Distinguishing features: Cruciplacolithus with narrow cross bars and a delicate net.
