==Taxonomy== Leptosynanceia was first formally described as a genus by the Dutch physician and zoologist Pieter Bleeker as a monotypic genus, with Synanceia asteroblepa, described by John Richardson from the coast of New Guinea, as its only species. The genus Leptosynanceia is classified within the tribe Synanceiini which is one of three tribes in the subfamily Synanceiinae within the family Scorpaenidae. Alternatively Synanceiidae may be considered a valid family, and in this case Synanceiini is considered as the subfamily Synanceiinae. The genus name is a combination of lepto meaning "thin" and Synanceia, the "typical" stonefish genus to which Richardson originally assigned this species, alluding to its more slender body than those stonefishes. The specific name is a compound of asteros, meaning "star", and blepos, meaning "see", to mean "stargazer", an allusion to the upturned eyes on the top of the head, similar to the unrelated stargazers of Uranoscopidae.
