Homolidae
de Haan, 1839
The membrane of the stomach-sac is comparatively thick compared to all other examined brachyuran species.
Dagnaudus petterdi
(Grant, 1905)
(

A, B)
The mesocardiac ossicle (I) has several posteriorly directed spines. The striped prepterocardiac ossicle (IIa) is more stronger than in
Dromiidae
and
Dynomenidae
, and does not reach the midline. A postpterocardiac ossicle (IIb) is not recognisable. The pectinal ossicle (VIII) has a triangular shape with seven accessory teeth.
Homola ranunculus
Guinot and Richer
de Forges, 1995 (

C–F) and
Homola barbata
(Fabricius, 1793)
The very thin, extensive, paired prepterocardiac ossicles (IIa) join at the midline of the antero dorsal gastric mill. The very small pectinal ossicle (VIII) has a triangular shape with seven accessory teeth. The middle pleuropyloric ossicle (XXXII) has a pointed shape.
Paramola cuvieri
(Risso, 1816)
The pectinal ossicle (VIII) has a triangular shape with 11 accessory teeth. The ventral keel of the anterior ossicle of the cardio-pyloric valve (XVI) is V-shaped. The posterior mesopyloric ossicle (XX) has on its ventral side an anterior as well as a posterior directed spine.
