“…The shape of the inner lateral teeth is also shared in Onchidoridoidea families, with hook-shaped inner lateral teeth, with the exception of Akiodorididae (Millen & Martynov, 2005;Hallas & Gosliner, 2015). Moreover, the spicules show a common pattern in families Goniodorididae and Onchidorididae, having overlapped sheets of spicules in the mantle and the tubercles are supported by spicule mounds (Penney et al, 2018;Paz-Sedano et al, 2021). Regarding the family Goniodorididae, the spicule pattern has been studied in species Okenia rosacea and Lophodoris danielsseni, in addition to the specimens of Goniodoris nodosa and Goniodoridella savignyi here included (Penney et al, 2018;Paz-Sedano et al, 2021).…”

Due to the shared pattern among genera, as well as the presence or absence of spicules within a same genus (e.g.…”

“…Goniodoris and Lophodoris lack dorsal or lateral papillae, the rhinophores are lamellated and have several gill branches around the anus and the radular formula is N × 1.1.0.1.1 (Table 1; Fig. 8) (Friele & Hansen, 1876;Wägele & Cervera, 2001;Ekimova et al, 2019;Paz-Sedano et al, 2021). However, only Lophodoris has long, strong spicules, and a dorsal crest (Table 1; Fig.…”

“…We describe the detailed anatomy of this specimen since specimens of T. fusca are not available anywhere. Specimens belonging to Lophodoris danielsseni (Friele & Hansen, 1876) were recently studied by some of us, and therefore, we have not included them in the present study to avoid redundancy (Paz-Sedano et al, 2021). Specimens belonging to the monotypic genus of Spahria, Spahria minima Risbec, 1928, were not available anywhere.…”

“…This approach of morphological analysis using digital techniques has been termed as morphomics (Chughtai et al, 2016;Ziegler et al, 2018). The use of microcomputed tomography has several advantages against classic dissections of specimens: (1) It allows to keep the integrity of specimens under study; (2) it could facilitate the systematic re-examination of rare and valuable specimens since natural history museums would allow to study exclusive type material of poorly described but delicate specimens; (3) it allows a comprehensive analysis of external and internal features in their natural context, ensuring that structures were not affected by the invasiveness of the traditionally conducted dissections (Candás et al, 2016;Moles et al, 2017;Penney et al, 2018;Ziegler et al, 2018;Marcondes Machado et al, 2019;Schillo et al, 2019;Paz-Sedano et al, 2021).…”

Detailed knowledge of the anatomy of the species is an essential element in taxonomic studies, since it allows the comparison and differentiation of separate groups of taxa. It becomes especially important when considering type species, as the subsequent identification of the species that compose the taxa is based on its characteristics, considered common in the group. However, despite its relevance, there are still numerous species without detailed descriptions, being especially significant among invertebrates. The family Goniodorididae is a little-known group of nudibranchs that includes eight recognized genera: Okenia, Goniodoris, Ancula, Lophodoris, Spahria, Trapania, Goniodoridella and Murphydoris. Several of their species are not completely described, including type species, and the systematics of the family is still unclear. Here we study in detail the external morphology and internal anatomy of the type species of five of the eight Goniodorididae genera using microcomputed tomography and scanning electron microscopy. We include the species Okenia elegans, Goniodoris nodosa, Ancula gibbosa, Goniodoridella savignyi and Murphydoris singaporensis as well as one species of Trapania, T. graeffei. We describe for the first time the detailed internal anatomy of the type species Goniodoridella savignyi. The diagnostic features of each genus are compared, and a preliminary framework is shown to clarify their systematics and identifications.
