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.

Lophodoris GO Sars，1878年，是一类淋巴腺科的小属，仅包括两个物种：Lophodoris danielsseni型物种（Friele＆Hansen，1876年）和Lophodoris scala Er。Marcus＆Ev。1970年，马库斯（Marcus）。萨尔（Sars，1878年）在脚注中竖立了洛菲多里斯（Lophodoris），没有发表评论。四十四年后，Odhner（1922）最终描述了类型种并定义了Lophodoris的诊断特征。丹尼尔森通过针尖支持的背not和锯齿状的叶缘，可以很好地区分食蟹科物种。但是，由于关于生殖系统或针状体模式的信息尚不清楚，因此对该物种的描述仍不完整。在目前的工作中，我们研究了新鲜收集的Lophodoris danielsseni的标本（Friele＆Hansen，1876）来自附近类型的地区。形态分析使用显微计算机断层摄影术以及夹层进行。我们包括了第一副扫描电子显微镜照片，显示的是小舌，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，并包括了属于淋病科的八属中的五属。结果首次显示了其在家族中的系统发育关系，分离了每个属。但是，必须对其他物种进行测序，以阐明食蟹科和属之间的进化关系。
