A separate fifth supraneural bone has been observed in the radiographs of D. chilensis (at least MCZ 8290, 36195, CAS 13706). The vertebrae are similar in shape to those of Diplomystes camposensis n. sp. (Fig. 29B —C) but lack the large foramina present in the abdominal vertebrae of Diplomystes camposensis n. sp. Diplomystes chilensis has 41 —43 (x = 42) vertebrae (Table 2). There are 16—19 abdominal and 23—27 caudal vertebrae. There are 10 to 12 pairs of ribs, the first pair is situated on the sixth or seventh vertebra. Epineural and epipleural bones are absent. Pectoral girdle and fin The Suspensorium of the pectoral girdle consists of a large bone, the posttem- porosupracleithrum. The posttemporal part of this complex bears a short dorsal limb.
