0E8F6F238C245C27B1E0BAB94EC7F4ED.taxon	diagnosis	Diagnosis. The single specimen is white with a narrow, granulated, orange mantle margin followed by a wide white band, a narrower black line, and then a white ring that also forms an elevated ridge on its inner margin. The central part is orange and shows a prominent and elevated white central ridge (Fig. 1 A). The holotype also has a black elongate mark in this central white ridge, which is missing in other individuals that were identified from images (see Distribution below). The species is not tuberculate but bears three ridges. Minute granules are present all over the white part of the dorsum. The yellow / orange rhinophores emerge from the inner white ring and bear 12 lamellae on each rhinophoral clavus. Rhinotubercles are absent. The dorsal anus lies near the posterior margin of the central orange part. Ventrally, the foot of Phyllidia fontjei sp. nov. has a white appearance and the oral tentacles are yellow-tipped. The hyponotum is rather transparent, and the dorsal orange and black lines show through (Fig. 1 B), as does a reddish gut content that perhaps comes from the dark orange sponge on which the animal was probably feeding (Fig. 1 C in situ).	en	Wägele, Heike, Raubold, Lina Marie, Papu, Adelfia, Undap, Nani, Yonow, Nathalie (2025): On two new Phyllidia species (Gastropoda, Nudibranchia, Doridina) and some histology from the Coral Triangle.

0E8F6F238C245C27B1E0BAB94EC7F4ED.taxon	etymology	Etymology. We name this species after our dear colleague Prof. Dr. Fontje Kaligis from Sam Ratulangi University, Manado, who initiated our Indonesian co-operation on describing marine Heterobranchia diversity around North Sulawesi. He passed away in September 2017, too early to see all the publications resulting from the joint collecting efforts. He enabled the extensive biodiversity studies in North Sulawesi and thus greatly extended our understanding of sea slugs in this area.	en	Wägele, Heike, Raubold, Lina Marie, Papu, Adelfia, Undap, Nani, Yonow, Nathalie (2025): On two new Phyllidia species (Gastropoda, Nudibranchia, Doridina) and some histology from the Coral Triangle.

F1CC7C9F5DDD5C039CD8F98D777272E2.taxon	diagnosis	Diagnosis. The mantle is elongate oval, white (rarely with a tinge of blue) with a clean-margined oval black area covering the central notum. Anteriorly, this black pigment forms a rounded U-shape around the first midline tubercle placed in front of the rhinophores (Fig. 2 A, B). Large white conical tubercles have yellow apices in the middle three rows and are only present in the black area. The broad white mantle skirt has smaller white tubercles decreasing in size towards the margin. Yellow rhinophores arise from translucent white rhinophoral sheaths that are distinctly raised; a rhinophoral tubercle with a yellow cap is present. The hyponotum is grey to white, and the foot sole has a black line in the mid-line; the top of the foot is white with no markings. The anus opening is placed ventrally, beautifully illustrated by Kato (2002), who also recorded the maximum size of 50 mm.	en	Wägele, Heike, Raubold, Lina Marie, Papu, Adelfia, Undap, Nani, Yonow, Nathalie (2025): On two new Phyllidia species (Gastropoda, Nudibranchia, Doridina) and some histology from the Coral Triangle.
