03D0AE235162FFD3FF73FF54FAA8106C.taxon	discussion	Remarks. Idanthyrsus bastidai n. sp. closely resembles Idanthyrsus sp. fide Chávez-López (2019) from Guerrero, Mexico. Both species have outer paleae with long, thin, straight spines; however, Idanthyrsus sp. has completely straight outer paleae and blunt nuchal hooks (Chávez-López 2019: Fig. 9 C, F) with limbation shorter than that in I. bastidai n. sp. that is characterized by slightly bent outer paleae (Fig. 2 A – B) and sharp nuchal hooks (Fig. 2 H). The coloration pattern also differs in both species, while Idanthyrsus sp. has the opercular peduncle and thorax strongly pigmented (Chávez-López 2019), I. bastidai n. sp. lacks apparent pigmentation (Fig. 1 A – C).	en	Chávez-López, Yessica (2021): Sabellariids (Annelida: Sedentaria: Sabellariidae) from shallow waters of the Gulf of Mexico and the Caribbean Sea, including three new species.

03D0AE235162FFD0FF73F9BAFECD12E5.taxon	discussion	Remarks. Idanthyrsus mikeli n. sp. resembles I. cretus Chamberlin, 1919 b, from Taboguilla Island, Panama, in having denticulate outer paleae with distally curved blades. However, these species differ in the morphology of the opercular paleae and nuchal hooks. Idanthyrsus mikeli n. sp. has outer paleae with broad transverse thecae in the basal region and 10 – 18 lateral denticles of similar size (Fig. 4 A – B), whereas I. cretus has outer paleae with thinner, less elevated, and compact thecae and 16 – 32 pairs of lateral denticles with finer denticles on one margin. The margins of the inner paleae are also different, being slightly annulated in I. mikeli n. sp. (Fig. 4 C, I) and completely smooth in I. cretus. Besides, I. mikeli n. sp. has blunt nuchal hooks with a long limbation that almost reaches the tip (Fig. 4 J), whereas in I. cretus nuchal hooks are sharp with short limbation that does not reach the convex region. Idanthyrsus mikeli n. sp. was found in the same aggregation as I. bastidai n. sp. Both species are distinguished mainly by the morphology of the outer paleae, presenting distally curved blades and short, curved marginal denticles in I. mikeli n. sp. (Fig. 4 A, H) and nearly straight blades with long, slender, straight marginal spines in I. bastidai n. sp. (Fig. 2 A – B).	en	Chávez-López, Yessica (2021): Sabellariids (Annelida: Sedentaria: Sabellariidae) from shallow waters of the Gulf of Mexico and the Caribbean Sea, including three new species.

03D0AE23516CFFD8FF73FE01FEC81705.taxon	discussion	Remarks. Sabellaria floridensis Hartman, 1944 and S. bella Grube, 1870 are two closely related species that share outer paleae with denticulate medial spike, and middle paleae with long and short forms. Grube (1870) made a brief description of S. bella from Desterro (now Florianópolis), Southern Brazil. Augener (1934) re-described the type material and illustrated the opercular paleae. Augener mentioned that outer paleae have 6 – 8 teeth with a central tooth larger than the others. The central tooth (or medial spike) has a fine, hair-like tip, with about 10 pairs of lateral teeth. The inner paleae have lateral teeth in the distal third of the blade. Hartman (1944) described S. floridensis from Lemon Bay, Florida with “ 22 pairs of prolonged outer paleae with two larger serrations on a side and a minute tooth at the outer base; six pairs of alternating long and short middle paleae; and 11 pairs of inner paleae terminating distally in a serrated edge ”. Also, Hartman (1944) recorded S. bella from Beaufort, North Carolina, and Independencia Bay, Peru, and she indicated in her identification key (Hartman 1944: p. 339 – 340), that the differences between these species were in the tip of the inner paleae, being entire in S. bella and serrate in S. floridensis. However, Augener (1934) described S. bella with serrate inner paleae as well. Thus, S. bella and S. floridensis share outer paleae with lateral teeth and denticulate medial spike, middle paleae with long and short forms, and inner paleae with serrate tip. Gruet & Lana (1988) commented on the differences in the opercular paleae of S. bella and S. bellis Hansen, 1882, both species from southern Brazil. Here, I focus on the description of S. bella. According Gruet & Lana (1988), Sabellaria bella has 20 pairs of outer paleae with 2 – 3 lateral spines (or teeth) on each side of a central or medial spike; 13 pairs of middle paleae, and 12 pairs of inner paleae. Some differences can be seen between the redescriptions of S. bella by Augener (1934) and by Gruet & Lana (1988). The medial spike has 5 – 6 lateral teeth in Gruet & Lana (1988) and not 10 pairs as Augener (1934) described. The long middle paleae have a more robust base, three times wider than the median blade region as seen in Augener’s illustrations (1934: Fig. 31 c), and almost twice as wide in the photographs and illustrations by Gruet & Lana (1988: Figs. 1 F, 2 D). On the other hand, the short middle paleae illustrated by Augener (1934: Fig. 31 b) are more concave, with recurved margins and with an abrupt sharp point at the apex, whereas Gruet & Lana (1988: Figs. 1 D – E, 2 C) show slightly concave paleae, with straighter margins and sharp apex. The inner palea has a serrate tip; however, these inner paleae have a bent blade in base, an angle of around 130 ° between handle and blade in Gruet & Lana (1988: Figs. 1 H, 2 E), while Augener (1934: Fig. 31 d) does not mention anything about the bending, but the angle between handle and blade is larger than 137 °. The differences observed can be due to the position where the paleae illustrated were taken from, lateral in Augener’s schemes, and ventral, upper, or another position as in Gruet & Lana’s photographs and drawings. Both Augener (1934) and Gruet & Lana (1988) examined one or two specimens, so it is difficult to infer the morphological variations that may be present in the opercular paleae of S. bella. Other records of S. bella have also included few specimens in their descriptions (Kirtley 1994: two spec.; Santos et al. 2011: four spec.; Liñero-Arana 2013: five spec.), and it has even been mentioned that S. bella is a solitary species (Santos et al. 2011). However, it is recommended that S. bella should be revised to expand its description and include variations in the opercular paleae to better delimit the specific diagnostic characters. Although Kirtley (1944) reviewed the type material of Sabellaria bella and S. floridensis, he neither emphasized the differences in the two species nor provided illustrations for S. bella, but took those of Gruet & Lana (1988) to illustrate the opercular morphology. Besides, there are some contradictions between his identification key to species of Sabellaria and the corresponding species descriptions. For example, Kirtley described S. bella with denticulate medial plume on the outer paleae, although in the key this species is grouped with those lacking this feature. Therefore, it is not possible to deduce which features he considered diagnostic for S. bella and S. floridensis. Regarding S. floridensis, Kirtley (1994) mentioned that there are morphological variations in the middle paleae, and that rigorous analysis is needed. He stated that some short middle paleae were slightly bent; however, in none of the specimens reviewed herein was this pattern identified. This is probably due to the number of samples reviewed (33 lots), the size of the specimens, or the localities of collection, as Kirtley (1994) included specimens from North Carolina to the Gulf of Mexico, Venezuela, and Panama (Atlantic coast), whereas most of the specimens reviewed here are from the Gulf of Mexico. Based on the above, some morphological differences between S. bella and S. floridensis (Figs. 7 – 12) can be determined. The medial plume of the outer paleae is slightly longer in S. floridensis (blade 1.6 times longer than medial spike, Figs. 7 A; 12 A) than in S. bella (blade twice longer than median spike, Fig. 8 F). The short middle paleae have blunt tips in S. floridensis (Figs. 7 F; 12 C) and sharp tips in S. bella (Fig. 8 H). The inner paleae are seen bent from the base, with marginal spines 1 / 3 – ¼ as long as distal middle spine in S. bella (Gruet & Lana 1988: p. 33, Figs. 1 H – I; 8 J) and straight paleae with marginal spines half as long as the distal middle spine in S. floridensis (Figs. 7 H; 12 E). Sabellaria floridensis has been found from the same aggregation as S. salazari n. sp. Both species are distinguished mainly by the characteristics of the medial spike in the outer paleae and the morphology of the middle paleae. Sabellaria salazari n. sp. has penicillate medial spike (Fig. 10 A – C) and only middle paleae in long-form (Fig. 10 D – E), while S. floridensis has denticulate medial spike (Fig. 7 A – B) and middle paleae in long and short forms (Fig. 7 C – F).	en	Chávez-López, Yessica (2021): Sabellariids (Annelida: Sedentaria: Sabellariidae) from shallow waters of the Gulf of Mexico and the Caribbean Sea, including three new species.

03D0AE235169FFC5FF73FE51FCBB12A5.taxon	discussion	Remarks. Sabellaria salazari n. sp. belongs to the group of species having penicillate medial spike and resembles Sabellaria sp. A sensu Uebelacker, 1988 from the Gulf of Mexico and S. wilsoni Lana & Gruet, 1989 from Brazil. Sabellaria salazari n. sp. has outer paleae with a longer medial spike, ½ of the total length of the outer palea. Uebelacker (1988) did not describe the length of the medial spike of Sabellaria sp. A, but illustrated the outer paleae with a spike almost longer than the blade of outer paleae (Uebelacker 1988: Fig. 49 - 6 c). Lana & Gruet (1989) described S. wilsoni with a short spike, ¼ – 1 / 6 as long as outer paleae, and reexamined Uebelacker’s material describing a longer medial spike, 1 / 3 - 1 / 5 as long as outer paleae of Sabellaria sp. A. According to Lana & Gruet (1989), Sabellaria sp. A has 5 – 6 pairs of lateral spines on outer paleae, and S. wilsoni has 3 – 6. Sabellaria salazari n. sp. has 3 – 5 pairs of lateral spines; however, it is very similar to Sabellaria sp. A because it has wider lateral spines on one side, whereas S. wilsoni has lateral spines of similar size on both sides. Sabellaria sp. A could belong to S. salazari n. sp. but it is necessary to review Uebelacker’s material to confirm this. Although Lana & Gruet (1989) described S. wilsoni as having “ middle paleae directed upward, nearly straight and just slightly bent inwards … ” it is necessary to consider the angle between the blade and the handle to estimate the inclination of the paleae. Lana & Gruet (1989) illustrated the middle paleae with a convex angle of 140 ° to 150 ° between the blade and handle, greater than that of S. salazari n. sp. (125 ° to 140 °); however, the position of the paleae of S. wilsoni is ventral and not lateral. Liñero-Arana (2013) recorded S. wilsoni for Venezuela and included scanning electron microscope photographs of paleae. However, the middle palea has a smaller angle (~ 100 ° in lateral view) than my estimate for S. wilsoni (140 – 150 ° in ventral view). In addition, the inner paleae are wider in the Venezuelan specimens (2 – 3 times longer than wide) than that of S. wilsoni (5 times longer than wide). Therefore, it is recommendable to review the type material of S. wilsoni to clarify the morphology of middle paleae and to consider the angle between the blade and the handle in the opercular paleae for future descriptions.	en	Chávez-López, Yessica (2021): Sabellariids (Annelida: Sedentaria: Sabellariidae) from shallow waters of the Gulf of Mexico and the Caribbean Sea, including three new species.
