Genus Kebira Row, 1909

TYPE SPECIES. — Kebira uteoides Row, 1909 by monotypy.

DIAGNOSIS. — Lelapiidae with a leuconoid organization. The choanoskeleton has large diactines and spicule tracts consisting of triactines with rudimentary paired actines. The atrial and cortical skeletons are composed of triactines and diactines.

DIAGNOSIS. — Lelapiidae with a sylleibid organization of the aquiferous system. The thick cortex is composed of an external layer of triactines and an internal layer of giant longitudinal diactines. The choanoskeleton is composed of radially arranged loose tracts of diapasons, originating proximally from unpaired actines of typical subatrial triactines. A well-developed atrial skeleton consists of tangential tri- and tetractines.

DESCRIPTION

The relationship of Paralelapia to Lelapia is quite similar to that of Grantiopsis and Kebira . In Paralelapia , the sylleibid aquiferous system and the organization of the choanoskeleton clearly have a radial organization, reminiscent of the Grantiidae . The loose spicular tracts are associat- ed proximally with the subatrial spicules, and the cortical skeleton is well-separated from the choanoskeleton (Fig. 39).
