Lophodoris G. O. Sars， 1878是gonioorididibranch的一个小属，它只包括两个种：模式种Lophodoris danielsseni （Friele & Hansen, 1876）和Lophodoris scala Er。马库斯和埃夫。马库斯,1970年。Sars（1878）在脚注中建立了Lophodoris，没有评论。44年后，Odhner（1922）最终描述了模式种，并定义了Lophodoris的诊断特征。在gonidoridididae物种中，Lophodoris danielsseni通过其背嵴和由针状体支撑的锯齿状notoredge而区分得很好。然而，由于对生殖系统或针状结构的信息尚不清楚，对该物种的描述仍然不完整。在本工作中，我们研究了在模式地点附近新采集的Lophodoris danielsseni （Friele & Hansen, 1876）标本。形态学分析是通过显微计算机断层扫描和解剖进行的。我们包括第一个扫描电子显微镜照片的radula，唇角质层，和阴茎棘。此外，我们使用条形码进行了初步的系统发育分析，包括隶属于gonioorididae的8个属中的5个。结果首次显示了其在科内的系统发育关系，并将每个属分开。然而，还需要进一步的物种测序来阐明goniodididae种和属之间的进化关系。
Lophodoris G. O. Sars, 1878 is a small genus of goniodoridid nudibranchs that includes only two species: the type species, Lophodoris danielsseni (Friele & Hansen, 1876), and Lophodoris scala Er. Marcus & Ev. Marcus, 1970. Sars (1878) erected Lophodoris in a footnote, without comment. Forty-four years later, Odhner (1922) finally described the type species and defined the diagnostic characteristics of Lophodoris. Lophodoris danielsseni is well differentiated among Goniodorididae species by a dorsal crest and jagged notum margin supported by spicules. However, the description of this species is still incomplete since information on the reproductive system or spicules pattern is not known. In the present work, we study freshly collected specimens of Lophodoris danielsseni (Friele & Hansen, 1876) from near the type locality. Morphological analyses are performed using micro-computed tomography as well as by dissections. We include the first scanning electron microscope photographs of the radula, labial cuticle, and penial spines. Moreover, we carry out a preliminary phylogenetic analysis using barcoding and including five out of eight genera belonging to the family Goniodorididae. Result shows for the first time its phylogenetic relationship within the family, separating each genus included. However, further species must be sequenced to clarify the evolutionary relationship among Goniodorididae species and genera.
