Genus

Iramena Boekschoten, 1970

Taxon description

Boekschoten, 1970

Diagmosis. Borings of probably ctenostome bryozoa, consisting of long (stolon) tunnels in an irregular network, with round to reniform (zooid cavity) apertures situated in alternating positions laterally to and close by the tunnels.

Iramena differs from Spathiapora in the round shape of the apertures (reniform or circular in the new genus, siltlike in Spathiapora) and in the closeness of the apertures to the main (stolon) tunnel. It differs from Terebripora which consist of diamond-shaped apertures situated directly above the tunnel.

Diagnosis: It is a boring system consisting in long primary tunnels little bifurcated, in irregular pattern with primary appertures, rounded to kidney-shaped, opening into a main cavity. Less conspicuos secondary tunnels open at approximately 90° (Mayoral, 1988). They are produced by ctenostomate bryozoans.
