Genus Ascyssa Haeckel, 1872 View in CoL

TYPE SPECIES. — Ascyssa troglodytes Haeckel, 1872 by subsequent designation (Dendy & Row 1913).

DIAGNOSIS. — Leucosoleniidae with a skeleton composed entirely of diactines.

DESCRIPTION

Haeckel (1872) described the two species of the genus Ascyssa from very few small specimens; representatives of this genus have not been found since. Since in the Calcaronea the first spicules to be secreted are diactines, these specimens may simply represent very young Leucosolenia , as suggested by Dendy & Row (1913). However, because Haeckel (1872) indicated that the specimen of A. acufera Haeckel, 1872 was sexually reproductive, this hypothesis is unlikely.
