Nuchequula is diagnosed by the presence of a distinct saddle-shaped nuchal marking and by the presence of a pigment-free, mitten-shaped region posteroventral to the pectoral-fin base. The genus comprises five species, N. blochii, N. pan, N. nuchalis, N. decora, and a new species described herein. Nuchequula mannusella, new species, is distinguished from its congeners by a unique pigmentation pattern on the dorsal fin and morphology of the lower jaw. Redescriptions are provided for the other species. A phylogenetic analysis based on morphological characters, including features of the light-organ system, indicates that Nuchequula is monophyletic.3098232 bytesapplication/pdfen-USQL1 .A436 no.3588 2007NuchequulaNuchequula mannusellaNuchequula -- Phylogeny.Leiognathidae -- TaiwanLeiognathidae -- Phylogeny.Fishes -- Taiwantext
