Diagnosis

The present diagnosis differs somewhat from that in Nielsen et al. (1999: 141) as the former Parasciadonus pauciradiatus is now reassigned to the genus Meteoria . Body slender, caudal part less than one third of standard length. Skin loose, scaleless and transparent. Small eyes deep-set. Mouth horizontal with lower jaw distinctly protruding. Minute skinflaps (12-19) along lateral line on each side of body. Palatines edentate. Anterior gill arch with 15 rakers developed as minute tubercles and a few minute filaments. Vertical fins joined. Rays in dorsal fin 78, in caudal fin 7, in anal fin 48, in pectoral fin 20 and in pelvic fin 0. Pectoral peduncle short, as high as long. Precaudal vertebrae 50 and total vertebrae 85, vertebral centra rectangular in lateral view. Urogenital opening covered ventrally by genital hood.

Comparisons Parasciadonus is most similar to Meteoria (see above).
