039E87DBF151FF9381A6FCACCADEA3D3.taxon	etymology	Etymology. The species name Bylgides samueli is in honor of our friend and polychaetologist M. Sc. Samuel Lucas Delgado da Silva Mendes. Geographic and Bathymetric Distribution. Known only from the type locality, Brazil: Santos Port Channel, São Paulo, at 10 meters depth.	en	Ogawa, Namy, Miranda, Vinícius Da Rocha, Rizzo, Alexandra E.

039E87DBF151FF9381A6FCACCADEA3D3.taxon	discussion	Remarks. Bylgides samueli sp. nov. is compared to other species in the genus in Table 1. The new species is morphologically similar to B. acutisetis and B. annenkovae as these are the only species presenting a nuchal lobe. However, the new species differs from the later in having smooth median antenna and ventral cirri, in contrast to the papillated condition observed in the other species. Bylgides samueli sp. nov. differs from B. acutisetis in possessing a pigmented prostomium. Bylgides samueli sp. nov. has very small, rather inconspicuous, cephalic peaks, while they are well developed in B. acutisetis and B. annenkovae. Notochaetae also can be used the distinguish the three species, Bylgides samueli sp. nov. has smooth notochaetae, in contrast to spinous notochaetae observed in the other two species. ...... continued on the next page ...... continued on the next page The characters described above, and also the type and distribution of papillae on the lateral antennae, the position of the first nephridial papillae, and the number of fascicles of notochaetae, are useful to distinguish Bylgides samueli sp. nov. from its congeners. In relation to B. cinthyae sp. nov., Bylgides samueli sp. nov. is distinguished based on the presence of the nuchal lobe, the smooth median antenna, unpigmented prostomium, three fascicles of notochaetae all smooth, and middle fascicle of neurochaetae with hooked tips. Fluorescence has not previously been documented in any other species of Bylgides. Expanding studies on the occurrence of this trait within the genus, and across the family, may not only increase the number of known cases but also provide a useful taxonomic character. Bylgides samueli sp. nov. exhibits a strong green fluorescence under violet illumination and a weaker red fluorescence under green light. This makes B. samueli sp. nov. the first species of the genus reported to display fluorescence.	en	Ogawa, Namy, Miranda, Vinícius Da Rocha, Rizzo, Alexandra E.

039E87DBF159FF9781A6FF5CC97DA377.taxon	etymology	Etymology. The species name Bylgides cinthyae sp. nov. is after the polychaetologist Dra. Cinthya Simone Gomes Santos, for her contribution to the study of the polychaetes, particularly nereidids, and to celebrate our friendship. Geographic and Bathymetric Distribution. Brazil: estuary of the Piauí River, Sergipe state at 1 – 27 meters depth.	en	Ogawa, Namy, Miranda, Vinícius Da Rocha, Rizzo, Alexandra E.

039E87DBF159FF9781A6FF5CC97DA377.taxon	discussion	Remarks. The new species is also compared with other congeners in Table 1. Bylgides cinthyae sp. nov. is unique in having smooth palps, elytra and dorsal cirri, and inconspicuous dorsal tubercles on posteriormost segments. Bylgides cinthyae sp. nov. resembles B. acutisetis in having a pigmented prostomium, the former has brown spots covering almost all the prostomium, while the latter has black pigments on the anterior half only. Both species can be differentiated based on presence of smooth palps, elytra and dorsal cirri, on B. cinthyae, whereas B. acutisetis present these structures ornamented. Both species also differ in the segmental origin of the nephridial papillae. The crescent-shaped pigmentation pattern presented in preserved specimens of Bylgides cinthyae sp. nov. is shared only with two congeners, B. elegans and B. macrolepidus. However, B. elegans has smooth elytra, in contrast to the papillated condition observed in B. macrolepidus. The three species can also be differentiated by the ventral cirri: smooth in B. cinthyae sp. nov., but papillated in the other two species. In addition, the absence of middle neurochaetae with hooked tips, in Bylgides cinthyae sp. nov., further separates it from both B. elegans and B. macrolepidus.	en	Ogawa, Namy, Miranda, Vinícius Da Rocha, Rizzo, Alexandra E.

The genus Pholoe is relatively small, with 17 species described worldwide, of which only six are reported to occur in the South Atlantic: P. courtneyae, P. inornata, P. minuta (Fabricius), P. microantennata, P. anoculata, and P. longa (Read & Fauchald, 2024). Among these, only the first four have been found in Brazil. Pholoe amandae sp. nov. differs from them based on a set of character, including: the absence of lateral antennae (present in P. longa and P. microantennata), ventral cirri with subdistal constriction, neuropodia with stylodes (absent in P. inornata, P. minuta, and P. anoculata), presence of eyes (absent in P. anoculata and P. courtneyae), presence of spinigers in chaetiger 1, elongated falcigers in the first two chaetigers, and a globular facial tubercle with papillae on the posterior margin. Pholoe amandae sp. nov. is similar to P. inornata, but they differ in the shape of the facial tubercle, globular in the former and small and papilliform in the later; in the subdistal constriction of the ventral cirri, and the spinigers chaetae in the first chaetiger that is present in Pholoe amandae sp. nov.	en	Ogawa, Namy, Miranda, Vinícius Da Rocha, Rizzo, Alexandra E.
