DC438877FFA8FF9049DBFD14F205FA3B.taxon	discussion	Remarks: In the original description Humes (1996 a) used many plesiomorphic characteristics commonly found in Asterocheres as diagnostic features for Phyllocheres, such as an exopod of antenna 1 - segmented; 3 - segmented endopod with a terminal segment bearing two short setae and a long seta. Oral cone short. Mandibular palp 2 - segmented with two terminal setae. Maxillule with large inner lobe having four setae; small outer lobe with three setae. Maxilla 2 - segmented. Maxilliped 5 - segmented, sexually dimorphic, with medial prominence on the second segment. Legs 1 - 4 biramous, with both rami 3 - segmented; second endopodal segments of all legs with two setae. Leg 5 with free segment bearing three setae. However, the few characteristics originally exclusive to the genus description have some differences that are observed in this redescription of Phyllocheres: two distal setae on the distal margin of the third endopodal segment of legs 1 and 2, exhibiting the armature formula (1,2,3) instead of (1,1 - I, 3). In addition, the distal margin of the third exopodal segment of leg 1 was originally described as having a spine, with the armature formula (III, I, 3), but, on this redescription, it is possible to confirm that the distal element on the segment is a seta, therefore having the same plesiomorphic condition as seen in Asterocheres (III, 1,3).	en	Bahiana, Bruna, Farias, Amilcar, Neves, Elizabeth, Johnsson, Rodrigo (2025): The taxonomic status of Phyllocheres Humes, 1996 and Neoasterocheres Canário et al., 2017, and three new Asterocheres Boeck, 1859 species (Siphonostomatoida, Asterocheridae) from Brazil.

DC438877FFAFFF9D49DBF98DF319FE11.taxon	discussion	In the redescription of Phyllocheres petalus, type species of the genus, the major striking diagnostic features, such as the armatures of the third exopodal segment of leg 1 as III, I, 3, the third endopodal segment of leg 1 as 1,1 + I, 3, and the third endopodal segment of leg 4 as 1,1 + 1,2, are not confirmed. Therefore, the unique species of Phyllocheres, based on the setation of legs 1 to 4, fits other genera, such as Asterocheres, and Neoasterocheres, among others. The redefinition of Asterocheres as proposed by Kim (2010) is built on the antennule segmentation and leg 3 endopod setation as 1 - 1 + I- 3 and left many species a s inquirendae. According to Kim (2010), Asterocheres has an aesthetasc on the 18 th segment (XXI), and therefore the 9 th segment refers to the fusion of the ancestral segments IX – XII. Setacheres, as proposed by Johnsson et al. (2016), gathered 8 of the species inquirendae previously assigned to Asterocheres, and it is characterized by the third endopodal segment of leg 3 having 1 - 2 - 3. Six other species inquirendae were grouped in Neoasterocheres according to Canário et al. (2017), which shows the antennule of female majorly 19 - segmented, with large aesthetasc on the 17 th segment and ancestral segments IX – XIII fused. However, among the other characteristics included in the diagnosis of Phyllocheres, Humes (1996) states that the female antennule is 19 - segmented with aesthetasc on segment 17. This condition implies the fusion of ancestral segments IX to XIII, the same apomorphic characteristic used by Canário et al. (2017) when establishing the genus Neoasterocheres to accommodate the species inquirendae excluded from Asterocheres. With the exclusion of setation characteristics mentioned above from the diagnosis of Phyllocheres, its major diagnostic features are the same as the ones used by Canário et al. (2017) to erect Neoasterocheres. Therefore, following the principle of priority of the International Code of Zoological Nomenclature, Neoasterocheres has to become a junior synonym of Phyllocheres.	en	Bahiana, Bruna, Farias, Amilcar, Neves, Elizabeth, Johnsson, Rodrigo (2025): The taxonomic status of Phyllocheres Humes, 1996 and Neoasterocheres Canário et al., 2017, and three new Asterocheres Boeck, 1859 species (Siphonostomatoida, Asterocheridae) from Brazil.

DC438877FFAFFF9D49DBF98DF319FE11.taxon	discussion	Remarks. The antennule has a well-defined condition regarding the proximal region by exhibiting the fused segment composed of the ancestral segments IX-XIII. the original diagnosis of Neoasterocheres proposed by Canário et al. (2017) defines the maxilliped as 6 - segmented, as seen in on N. breviseta Canário et al., 2017, however, N. humesi Varela, 2012, N. scutatus Stock, 1966, N. serrulatus Humes, 1996, N. dysideae Humes, 1996, N. enewetakensis Humes, 1997, N. rotundus Malt, 1991 exhibit a 5 - segmented maxilliped. As Phyllocheres also has a 5 - segmented maxilliped (Humes, 1996 a), the diagnosis of the maxilliped now acknowledges this variation. Additionally, Asterocheres spongus Johnsson, 2002, species treated as inquirendum by Kim (2010) in his redefinition of Asterocheres, also exhibits the ninth antennule segment composed of the fused ancestral segments IX – XIII, with the aesthetasc on the 17 th segment, plus a terminal segment and a 5 - segmented maxilliped. By presenting this set of features, this species should also be reassigned to the genus Phyllocheres as P. spongus (Johnsson, 2002).	en	Bahiana, Bruna, Farias, Amilcar, Neves, Elizabeth, Johnsson, Rodrigo (2025): The taxonomic status of Phyllocheres Humes, 1996 and Neoasterocheres Canário et al., 2017, and three new Asterocheres Boeck, 1859 species (Siphonostomatoida, Asterocheridae) from Brazil.

DC438877FFAFFF9D49DBF98DF319FE11.taxon	discussion	Phyllocheres petalus shares the 19 - segmented female antennule with aesthetasc on the 17 th segment with seven congeners: P. breviseta (Canário, Rocha, Neves & Johnsson, 2017), P. dysideae (Humes, 1996), P. enewetakensis (Humes, 1997), P. humesi (Varela, 2012), P. rotundus (Malt, 1991), P. scutatus (Stock, 1966), and P. serrulatus (Humes, 1996). Phyllocheres petalus can be differentiated from P. breviseta, P. humesi, and P. rotundus by exhibiting three setae on the antennal exopod, while those species exhibit only two setae (Malt 1991; Varela 2012; Canário et al. 2017). The mandibular palp on P. petalus, is 2 - segmented, differing from P. scutatus, which is 1 - segmented (Stock 1966 a). And ultimately, P. petalus exhibits three equally sized setae on the free segment of leg 5, differing from P. dysideae, P. spongus, and P. enewetakensi, which show three unequally-sized setae, and also from P. serrulatus, which shows only two equally sized setae (Humes 1996 a; 1996 b; Humes 1997; Johnsson 2002; Canário et al. 2017). Phyllocheres petalus exhibits produced epimera on both posterolateral margins of the cephalosome, reaching beyond the anterior margin of the genital somite in both sexes, creating a half-moon-shaped cephalosome as an exclusive feature for the species.	en	Bahiana, Bruna, Farias, Amilcar, Neves, Elizabeth, Johnsson, Rodrigo (2025): The taxonomic status of Phyllocheres Humes, 1996 and Neoasterocheres Canário et al., 2017, and three new Asterocheres Boeck, 1859 species (Siphonostomatoida, Asterocheridae) from Brazil.

DC438877FFA2FF9E49DBFD38F5F6F937.taxon	discussion	Remarks: Asterocheres is the largest genus of the Asterocheridae family, containing 104 valid species (Walter & Boxshall 2025). Due to its many species, it can be divided into two groups: the asterocherids with female antennules containing 21 segments and the asterocherids with the female antennule containing 19 or 20 segments (Conradi & Bandera 2011). Asterocheres quiteriae sp. nov. is included in the group of species with 21 - segmented female antennules and shares with those species a 2 - segmented mandibular palp and 6 - segmented maxilliped. Asterocheres quiteriae sp. nov. shares these characteristics with 16 congeners: A. aesthetes Ho, 1984; A. culicis Kim & Lee, 2024; A. cuspis Kim, 2016; A. dokdoicus Kim & Lee, 2024; A. fici Kim & Lee, 2024; A. flustrae Ivanenko & Smurov, 1997; A. geminus Kim & Lee, 2024; A. genodon Stock, 1966; A. horridus Kim, 2016; A. lilljeborgi Boeck, 1859; A. nidorelliae Reyes-González & Suárez-Morales, 2021; A. nodulosus Kim & Lee, 2024; A. peniculatus Kim, 2010; A. reginae Boxshall & Huys, 1994; A. simulans Scott, 1898; A. tubiporae Kim, 2004. Asterocheres quiteriae sp. nov. can be distinguished from nine of these species based on the length of the siphon; this new species has the oral cone reaching close to the first leg intercoxal plate. This pattern is different from A. aesthetes, A. cuspis, A. flustrae, A. lilljeborgi, A. nidorelliae, A. nodulosus, A. reginae, A. simulans, and A. tubiporae whose siphons do not reach beyond the maxilliped (Boeck 1859; Boxshall & Huys 1994; Scott 1898; Ivanenko & Smurov 1997; Kim 2004 a; Kim 2016; Reyes-González & Suárez-Morales 2021; Kim & Lee 2024). Asterocheres quiteriae sp. nov. exhibits two major apomorphies: the exopodal segment of the antenna with a long terminal seta and a small subdistal seta, and leg 5 armed with two equal setae. In contrast, A. culicis, A. dokdoicus, A. fici, A. geminus, A. genodon, A. horridus, and A. peniculatus have three setae on the exopodal segment of the antenna and leg 5 armed with three setae (Stock 1966 b; Kim 2010; 2016; Kim & Lee 2024).	en	Bahiana, Bruna, Farias, Amilcar, Neves, Elizabeth, Johnsson, Rodrigo (2025): The taxonomic status of Phyllocheres Humes, 1996 and Neoasterocheres Canário et al., 2017, and three new Asterocheres Boeck, 1859 species (Siphonostomatoida, Asterocheridae) from Brazil.

DC438877FFBBFF8349DBF9F6F210FC65.taxon	discussion	Remarks: Asterocheres angelicae sp. nov. belongs to the group of Asterocheres species with 20 - segmented antennules, a feature shared with 26 congeners: A. banderaae Kim & Lee, 2023; A. bimbarrensis Bispo, Johnsson & Neves, 2006; A. crinoidicola Humes, 2000; A. espinosai Varela, Ortiz & Lalana, 2007, A. eurychelatus Kim & Lee, 2024, A. galeatus Kim, 2010, A. halichondriae Stock, 1966, A. maxillatus Stock, 1987, A. neptunei Johnsson, 2001, A. oricurvus Kim, 2010, A. planus Kim, 2010, A. proboscideus Stock, 1966, A. processus Kim & Lee, 2024, A. quadridens Kim, 2016, A. rai Kim & Min, 2013, A. scutellatus Kim & Lee, 2024, A. sensilis Kim, 2010, A. simplex Schirl, 1973, A. siphunculus Bahia, Canário, Neves & Johnsson, 2012, A. spinosus Kim & Min, 2013, A. stocki Nair & Pillai, 1984, A. tenuipes Kim, 2010, A. tetraodontis Kim, & Lee, 2024, A. tricuspis Kim, 2010, A. tridentatus Kim & Lee, 2024, A. trisetatus Kim, 2010. Asterocheres angelicae sp. nov. can be differentiated from A. banderaae, A. eurychelatus, A. galeatus, A. halichondriae, A. oricurvus, A. planus, A. processus, A. quadridens, A. rai, A. scutellatus, A. sensilis, A. spinosus, A. tenuipes, A. tetraodontis, A. tricuspis, A. tridentatus, and A. trisetatus by having a 5 - segmented maxilliped, while those species exhibit 6 - segmented maxilliped (Stock 1966 b; Kim 2010; 2016; Kim & Min 2013; Kim & Lee 2023; 2024). Oral cone reaching leg 1 intercoxal plate on the new species easily differentiates it from A. proboscideus, which has the oral cone reaching the caudal rami (Stock 1966 b; Bandera & Conradi 2013). Asterocheres angelicae sp. nov. shows two distal setae on the antennal exopod, differing from A. crinoidicola, A. halicondriae, A. maxillatus, and A. neptunei which show three setae (Stock 1966 b; 1987; Humes 2000; Johnsson et al. 2001; Bandera & Conradi 2013). Finally, A. angelicae sp. nov. can be easily differentiated from A. bimbarrensis, A. espinosai, A. simplex, and A. stocki by having a 1 - segmented, while congeners have 2 - segmented mandibular palp (Schirl 1973; Nair & Pillai 1984; Varela 2012; Bispo et al. 2006; Varela et al. 2007)	en	Bahiana, Bruna, Farias, Amilcar, Neves, Elizabeth, Johnsson, Rodrigo (2025): The taxonomic status of Phyllocheres Humes, 1996 and Neoasterocheres Canário et al., 2017, and three new Asterocheres Boeck, 1859 species (Siphonostomatoida, Asterocheridae) from Brazil.
