Lyreidus tridentatus
de Haan, 1841 and
Lysirude channeri
(Wood-Mason, 1887)
For the description of the foregut structures I am using
Ranina ranina
as the example for all of these species.
The pectinal ossicle (VIII) is horseshoe-shaped with one accessory tooth. The inferior lateral cardiac ossicle (XIII) has a clearly lateral connection to the subdentate ossicle (XIV). The ossicle (“XVII–XXIII”) is observed as a mixed ossicle. Ossicles XIX and XIXa are not recognisable.
Lyreidus brevifrons
Sakai, 1937
The unpaired propyloric ossicle (VI) is inclined about 45° in the posterior direction.
