内容記述 | The genus Goniobranchus Pease, 1866 is a well-supported monophyletic clade that consists of 57 species and they have an ovoid body shape and have different mantle glands underneath their mantle. Certain Goniocranchus species are highly variable in their gross external morphology and this is notably observed in the red-reticulate Goniobranchus spp. and the 'white mantle' Goniobranchus. Both morphological and molecular data were implemented to describe or classify the Goniobrachus nudibranchs in this study. The molecular analyses of the red-reticulate Goniobranchus spp. identified five species-level clades, but none of the clades' morphotypes matched exactly with the original descriptions of G. tinctorius or G. reticulatus. The existence of multiple species-level clades in the Goniobranchus red-reticulate group suggests this is a group of closely related species, comprising at least five undescribed taxa. Molecular data of Goniobranchus nudibranchs with white bodies and various marginal bands recovered six species groups corresponding to the described species Goniobranchus albonares, G. preciosus, G. rubrocornutus, G. sinensis and G. verrieri as well as one undescribed species, G. fabulus. Notably, each of G. preciosus, G. sinensis, G. rubrocornutus, G. verrieri, and Goniobranchus fabulus exhibit colour variation and polymorphism, suggesting that colour patterns may not always be useful in the identification of species in the 'white Goniobranchus' group. The most comprehensive molecular phylogeny of Goniobranchus to date was generated using mitochondrial cytochrome coxidase subunit I (COI), 16S ribosomal DNA (16S rDNA), and the nuclear gene Histone 3 (H3) sequences, with additional Automatic Barcode Gap Discovery (ABGD) and the Bayesian Poisson Tree Process (bPTP) analyses. The analyses recovered 36 described species of Goniobranchus and at least 27 undescribed species. Ten species complexes were recovered in these analyses, and their taxonomic problems were discussed in detail. |
