Nomenclatorial problem

The problem concerns a spider genus in the family Zodariidae.

In 1953 J. Denis describes (in French) three species in a genus ‘Acanthinozodium’ without designating a type species. He does not do this because the publication in which he wanted to describe the genus is greatly delayed and only appears in 1966. In the latter paper he describes Acanthinozodium spinosum and mentions that this should have been the type species “Le genre Acantinozodium est intermédiaire entre les Diores et les Zodarium: son type aurait dû être A. spinulosum : mais par suite du retard apporté à la publication de cette etude, j’ai été amené à en donner une description très sommaire ” (the 1953 paper).
In 1991, in a revision of the family, I considered Acanthinozodium as a valid genus and designated the first species described in the 1953 paper (A. cirrisulcatum) as the type species.  In the same paper the genus was considered a senior synonym of Zodariellum Andreeva & Tyschenko, 1968 described in Cyrillic. This paper is full of nomenclatorial mistakes e.g.. heading Lodariellum instead of Zodariellum; Z. continentalis is mentioned in the English abstract as belonging to the three new Zodarion species in the paper but described in Zodariellum, the authorsip of the taxa changes within the paper,  etc).
In 2001 Marusik & Koponen consider Acanthinozodium a nomen nudum because no type species was designated at the first publication of the name. As a result, all species considered congeneric with Acanthinozodium are now in Zodariellum.
The main problem is that the inclusion of these species was based on the palpal characters of “Z. continentalis” which is in fact a Zodarion.
In the meantime we have found some characters that allow us to define Acanthinozodium more precisely and remove Zodariellum from its synonymy. The main question to be solved though is whether Acanthinozodium is valid.

We would appreciate your comments.
