| 英文摘要 | The previously alleged 'semionotid' fish Asialepidotus shingyiensis from the Middle Triassic (Ladinian) marine deposits of Guizhou and Yunnan, China has recently been identified as a halecomorph, but its phylogenetic relationships with other halecomorphs remain controversial. This taxon was successively placed in different halecomorph orders: Amiiformes, Parasemionotiformes and 'Panxianichthyiformes'. Here, a detailed redescription of Asialepidotus is presented based upon a comparative study of the original material with 50 new specimens. Newly recognized anatomical information includes a V-shaped rostral, paired vomers, a toothed parasphenoid, a dermosphenotic with a canal-bearing innerorbital flange, a splint-like quadratojugal, a branch of the infraorbital sensory canal in the maxilla, and many elements in the hyoid and branchial apparatuses and the lower jaw. Results of a cladistic analysis incorporating these new data indicate that the 'Panxianichthyiformes' is a poorly defined, paraphylectic grade; Asialepidotus is not sister to Panxianichthys as previously suggested; instead, it is more derived than Panxianichthys and consists of the sister taxon of the clade Robustichthys plus Jurassic-Cretaceous ionoscopiforms. This phylogenetic reassessment of Asialepidotus extends the stratigraphic range of the Ionoscopiformes in China by similar to 4 Myr and supports the hypothesis that the early ionoscopiform diversification was already established by the Middle Triassic. |
