The holotype and only known specimen is a poorly preserved partial, and elongated skull from Emsian-aged strata in Sichuan. The skull may be around {{convert|8.5|cm|abbr=on}} in length.{{cite book|last=Denison|first=Robert|title=Placodermi Volume 2 of Handbook of Paleoichthyology'|year=1978|publisher=Gustav Fischer Verlag|location=Stuttgart New York|isbn=978-0-89574-027-4|pages=120}}

Denison 1978 questions Neopetalichthys' placement within Petalichthyida, regarding it as Placodermi incertae sedis, though he does acknowledge that the skull has anatomical features in common with petalichthyids.). According to Zhu's 1991 redescription of Diandongpetalichthys,Zhu, M. "New information on Diandongpetalichthys (Placodermi: Petalichthyida)." Early vertebrates and related problems of evolutionary biology. Science Press, Beijing (1991): 179-192. Neopetalichthys' status as a petalichthyid is confirmed, though, in that study, it is regarded as a basal incertae sedis.{{cite journal | url=http://www.ivpp.cas.cn/cbw/gjzdwxb/xbwzxz/200812/W020090813369930445831.pdf | title=A NEW MACROPETALICHTHYID FROM CHINA, WITH SPECIAL REFERENCE TO THE ZOOGEOGRAPHY OF THE MACROPETALICHTHYIDAE (PLACODERMI) |author1=Zhu, Min |author2=Wang, Junqing |name-list-style=amp | journal=Vertebrata PalAsiatica |date=October 1996 | volume=34 | issue=4 | pages=253–268}}

Quasipetalichthys is possibly closely related to Neopetalichthys, and may or may not be placed together within Quasipetalichthyidae.
