Archocyrtium Deflandre, 1972 sensu Holdsworth (1973)

Archocyrtium Deflandre, 1972b: 15 ; 1960: 216 (nomen nudum). — Holdsworth 1973: 122.

Allocyrtium Afanasieva, 1986: 31 (n. syn.)

TYPE SPECIES. — Archocyrtium riedeli Deflandre, 1960 ( Deflandre 1960: 216, pl. 1, fig. 17, nomen nudum); Deflandre 1972a: 3537, pl. 4, fig. 4-5; 1972b: 15.

AGE AND LOCATION OF TYPE MATERIAL. — Visean (Lower Carboniferous), Cabrières, Hérault, Montagne Noire, France.

TAXON CODE. — 219.

STATUS. — Valid.

DIAGNOSIS. — “Céphalis sphérique perforé surmonté d’une corne apicale ou subapicale costulée, avec un podome de trois cornes autour d’un pylome dont le bord peut se prolonger entre les cornes, constituant ainsi un pseudothorax jamais perforé. Système trabéculaire interne comportant quatre actines, parfois conservé partiellement, souvent disparu” ( Deflandre 1972b: 15).

REVISED DIAGNOSIS. — “A single, perforate lattice shell with only four main spines, three of which are positioned symmetrically in the pylome margin, the fourth constituting an apical spine positioned at the opposite pole from the pylome centre. Internal spicules are completely absent in some species but well developed in others. A pylome net is invariably absent.” ( Holdsworth 1973: 122).
