Recent developments on the morphology of the brachyuran foregut ossicles and gastric teeth Author Brösing, Andreas text Zootaxa 2010 2510 1 44 journal article 10.5281/zenodo.294144 ce99f918-054b-4464-a0eb-b176579eb998 1175-5326 294144 Gecarcinidae MacLeay, 1838 Cardisoma armatum Herklots, 1851 ( Fig. 28 ) and Dicoplax hirtipes (Dana, 1851) Ossicles I, II and IIb are inclined about 45° in the antero ventral direction. The exopyloric ossicle (IV) is enlarged. The unpaired propyloric ossicle (VI) is nearly vertical. The pectinal ossicle (VIII) is ring-shaped with 13 accessory teeth. The inferior lateral cardiac ossicle (XIII) has a long oval shape and two ventrally directed crossed tips; on its dorsal part it has a posterior directed connection-piece to the subdentate ossicle (XIV). The posterior area of the prepectinal ossicle (IX) is remarkably extended. The ossicle (XIV) has a flattened postero ventral expansion. The lateral ossicle of the cardio-pyloric valve (XVIII) is extremely increased in size and covers the lateral side of the cardio-pyloric valve. Ossicles XXIa and XXIII are not recognisable.
