Laudoniidae
Taxonomy
Laudoniidae was named by Lieberman (1998) [Lieberman (1998) attributes both the family and subfamily name to Palmer and Repina (1993), but that reference only erected the subfamily, so I'm giving the family to Lieberman (1998).]. It was considered paraphyletic by Lieberman (1999).
It was assigned to Olenelloidea by Lieberman (1999).
It was assigned to Olenelloidea by Lieberman (1999).
