| 摘要 | dagger Paralycoptera wui Chang & Chou, 1977 from the Early Cretaceous of China is redescribed herein through a re-examination of the original materials, as well as observations on some newly collected specimens. The use of the peeling method has revealed much of the new or revised information on its osteology, e.g. aspects of the nasal, infraorbitals, retroarticular, preopercle, extrascapular, basihyal toothplate, epineural, pelvic fin, caudal skeleton and scales. The phylogenetic relationships of dagger Paralycoptera and other osteoglossomorphs are re-evaluated. The cladistic analysis largely agrees with the previous hypothesis that dagger Paralycoptera is not a dagger lycopterid, but rather a stem osteoglossoid. dagger Paralycoptera is excluded from notopteroids and exhibits the following derived characters of the Osteoglossoidei: (1) palatal area behind and below orbit completely covered by infraorbitals; (2) jaw articulation under posterior portion of orbit; (3) opercle depth twice or more its width; (4) first pectoral fin ray much enlarged and long, extending posteriorly beyond origin of pelvic fin. dagger Singida and dagger Phareodus are regarded as different levels of osteoglossoids above dagger Paralycoptera. dagger Singida shares the following derived characters with dagger Phareodus plus extant osteoglossoids: (1) jaw articulation posterior to orbit; (2) anterior process of hyomandibula in contact with entopterygoid; (3) subopercle small and anterior to opercle. dagger Phareodus shares the following derived characters with extant osteoglossoids: (1) supraorbital and otic sensory canals connected; (2) one uroneural; (3) reticulate furrows present over entire scale.
