An undescribed lobate ctenophore, Lobatolampea
tetragona gen. nov. & spec. nov., representing a new
family, from Japan . . .
Lobatolampea tetragona gen. nov. & spec. nov. was collected from
coastal waters of Ise Bay, near Toba, Pacific coast of middle Japan.
It assumes a medusoid bell-shape when floating, but is nearly
discshaped when resting on the bottom. It is characterized by four
C-shaped gonads present on the distal part of the subpharyngeal
meridional canals, beyond the oral end of the comb rows. "Primitive"
oral lobes are also formed and ctenes are found at the site of the
presumptive auricles. The morphology of this species differs from
any previously described larval or adult form, and is intermediate
between the orders Cydippida and Lobata. The larvae are of the
cydippid type.
Key words: Ctenophora; Lobatolampeidae fam. nov.; Lobatolampea
tetragona gen. nov. & spec. nov.; lobate; medusoid; Japan.
ETC.
