03D03123FFD9BF07D0D84918FBA7EE67.taxon	discussion	Remarks. Loimia has a confused taxonomic history, with several taxa mistakenly reported worldwide. The most useful morphological characters to identify the species within this genus are: (1) shape and position of the lobes on segments 1 and 3; (2) shape of ventral glandular shields and number of segments on which they are present; (3) number of uncinial teeth (from both anterior and posterior regions) as well as the general morphology of the uncini, including presence of processes and filaments (Hutchings & Glasby 1988, 1995; Hutchings 1997; Londoño-Mesa and Carrera-Parra 2005; Londoño-Mesa 2009). We agree with Hutchings and Glasby (1988, 1995) and Londoño-Mesa (2009) regarding the critical importance of the morphology of anterior lobes and uncini, but we have herein recognized additional characters which are useful to distinguish between species of Loimia, or at least for those occurring off the Brazilian coast. The presence of eyespots and their size, for example, should also be considered in species descriptions, as well as the number, arrangement and shape of mid-ventral glandular shields, as discussed below.	en	Carrerette, Orlemir, Nogueira, João Miguel De Matos (2015): The genus Loimia Malmgren, 1866 (Annelida: Terebellidae) off the Brazilian coast, with description of three new species and notes on some morphological characters of the genus.

03D03123FFDCBF0AD0D84A95FC22EB78.taxon	description	Description. Small, fragile, cylindrical worms, not markedly swollen anteriorly (Figs 3 C – E; 5 A, C), anterior segments compact, all about same length except for shorter segments 1 and 2; chaetigers progressively longer on segments 12 – 20. Complete specimens with 26 – 48 (26) segments, 3.7 – 5.1 (4.1) mm long, 0.3 – 0.9 (0.3) mm wide (Table 1). Preserved body colourless, except for dark brown transverse ventral band at intersegmental line of segments 2 and 3. Prostomium at base of dorsal side of upper lip; basal part of prostomium with 2 rows of eyespots, upper row with 5 – 6 large eyespots at each side, progressively smaller laterally, arranged in oblique band (Fig. 3 A, C, G); other row at posterior margin of basal part of prostomium, with much smaller, irregularly scattered eyespots, in broad band; distal part of prostomium forming shelf-like process from which short and cilindrical buccal tentacles originate (Figs 3 A – G; 5 A – F). Peristomium restricted to lips; upper lip short, wider than long, nearly circular and folded laterally; lower lip short, rectangular, cushion-like, partially hidden by membrane connecting lobes of segment 1 (Figs 3 A – G; 5 A – I). Segment 1 visible entirely, dorsally short, with relatively short paired lobes originating dorso-laterally, aligned with line of notopodia; lobes with oblique dorsal margins, continuing across ventrum as low lobes; distally rounded, roughly circular, barely reaching mid-length of upper lip, then oblique towards lower lip; tips and ventral edges connected by membrane (Figs 3 A – G; 5 A – B, E – F). Segment 2 short, conspicuous laterally and dorsally, ventrally separated from segment 3 forming first mid-ventral shield (Figs 3 A – F; 5 B, F); segment 3 longer than the previous ones, with paired low lobes, thin, ear-like, distally rounded; with wide bases about as large as tips of lobes, originating dorso-laterally, near anterior margin of first pair of notopodia (these on segment 4), terminating aligned with ventral edge of neuropodia, laterally to partially fused mid-ventral shield of segments 3 – 4 (Figs 3 A – G; 5 A – B, E – I); dorsal margins oblique, terminating far from bases of branchiae (Figs 3 A – G; 5 A – B, E – I); segment 4 partially fused mid-ventrally to the mid-ventral shield of segment 3; following anterior segments about same size. Three pairs of branching branchiae, on segments 2 – 4, each with short basal stem (Fig. 5 C – F); pairs of branchiae progressively shorter, all ventrally aligned. Rectangular, smooth, swollen midventral shields on segments 2 – 12, slightly crenulated and completely separated from each other, smooth from segment 5, progressively narrower to last (Figs 3 A – B, D – F; 5 A – B); a distinctly narrower pad on segment 13 is frequently present, divided by two transverse bands; from segment 14, shields replaced by mid-ventral groove extending posteriorly (Figs 3 A – B; 5 A – B). Cylindrical, short notopodia, on segments 4 – 20, bearing narrowlywinged chaetae in both rows, those from posterior row longer, with wings on distal half of chaetae (Figs 4 A – D; 6 A – C). Neuropodia beginning from segment 5, as low rectangular ridges slightly raised from surface of body until segment on which notopodia terminate (Figs 3 A – B, D – F; 5 A – B, E – F), thereafter as elongate, prominent pinnules (Fig. 3 A, H); neuropodia bearing pectinate uncini, arranged in double rows on segments 11 – 20, tori aligned ventrolaterally from segment 5 to posterior body, rows partially intercalated on ventral edges of neuropodia, then completely separate, uncini in crest-to-crest to back-to-back arrangement (Figs 4 D; 6 F – G). Uncini pectinate, higher than long, with concave base, prominent, triangular heel directed backwards, and prow downwardly directed, continuing as long ligament (Figs 4 E – H; 6 E – I); uncini of region with notopodia with six teeth, progressively shorter upwards, basal-most tooth larger, in line with prow, distal-most tooth as short spine on top, barely visible under light microscope, conspicuous under SEM (Figs 4 D – F; 6 E – H); neuropodia from region after notopodia terminate with uncini with up to 6 – 7 teeth, frequently varying within tori, sometimes distal-most tooth sided by one minute tooth at each lateral (Figs 4 G; 6 I). Nephridial and genital papillae not visible. Anus surrounded by crown of short, rounded papillae (Fig. 3 H).	en	Carrerette, Orlemir, Nogueira, João Miguel De Matos (2015): The genus Loimia Malmgren, 1866 (Annelida: Terebellidae) off the Brazilian coast, with description of three new species and notes on some morphological characters of the genus.

03D03123FFDCBF0AD0D84A95FC22EB78.taxon	discussion	Remarks. Loimia megaoculata sp. nov., is shorter than most species of Loimia and has large eyespots, to our knowledge not found in any other species of the genus. Loima megaoculata sp. nov., has eyespots arranged in two rows, the upper one with 5 – 6 large eyespots on each side, beginning dorso-laterally and progressively smaller lateral and upwards, with other row at posterior margin of basal part of prostomium, with small, irregularly scattered eyespots. Two other species of Loimia have eyespots on basal part of prostomium, L. triloba Hutchings & Glasby, 1988 (Table 2), originally described from Australia (Hutchings & Glasby 1988, 1995; Londonõ-Mesa & Carrera-Parra 2005; Londonõ-Mesa 2009) and L. medusa (Hutchings & Glasby 1995; JMMN personal observation). In addition to the eyespots, L. triloba also has uncini with 5 – 6 teeth (Fig. 2 D, F, K, L), similar to L. megaoculata sp. nov. However, L. triloba differs from L. megaoculata sp. nov., in having two rows of small eyespots, arranged laterally, lacking larger eyespots as in L. megaoculata sp. nov. In addition, L. triloba has lobes of the segment 1 continuing dorsally as free, completely encircling the body, lateral lobes of segment 3 with the base narrower than the tip, and a pair of shorter lateral lobes on segment 4 (Fig. 1 B, G). In contrast, in L. megaoculata sp. nov., the lobes of the segment 1 originate dorso-laterally, at line of notopodia, with large mid-dorsal gap, the lobes of segment 3 have bases at least as wide as tips, and there are no lobes on segment 4. The neotype of L. medusa also has eyespots, but few, only laterally (Hutchings & Glasby 1995; JMMN, personal observation). Loimia medusa differs from L. megaoculata sp. nov., however, in addition to the arrangement and shape of the eyespots, by having a pair of large, high and circular lobes on segment 1; nearly circular ones on segment 3, with narrower base than tip, upper dorsal margins reaching the bases of the branchiae; rectangular and progressively longer mid-ventral shields, as well as uncini with 4 – 5 teeth only (Figs 1 D, J; 2 C, G, L). In contrast, L. megaoculata sp. nov., also has distally rounded, roughly circular lobes of segment 1, but they are distinctly shorter than those of L. medusa, the lobes of segment 3 have bases at least as wide as tips, the mid-ventral shields are also rectangular, but they are evenly-sized, instead of progressively longer, and the uncini have 6 – 7 teeth. Four other species resemble L. megaoculata sp. nov., with regard to the presence of ventral shields extending to segment 12, L. bandera, L. batilla, L. medusa and L. bermudensis Verrill, 1900, although in L. megaoculata sp. nov., a distinctly narrower pad on segment 13 is also frequently present. A comparison of all these species is provided in Table 2, together with the other species used for comparisons with the remaining species described in this paper. TABLE 2.

In addition, the mid-dorsal gap between the lobes of the segment 1 of L. bandera is distinctly narrower than present in L. megaoculata sp. nov. (Fig. 1 F), while the lobes of the segment 3 are larger and oblique, instead of rounded. The Australian species L. batilla also differs from L. megaoculata sp. nov., in the same characters as L. bandera, i. e., prostomium lacking eyespots, and uncinial teeth exhibiting minor differences in size from the basalto the distalmost teeth (see Table 2). Loimia bermudensis Verrill, 1900, which was described from Bermuda and has never been collected again since the original description (Londoño-Mesa 2009), differs from L. megaoculata sp. nov., in the number of uncinial teeth, 5 teeth per uncinus throughout the body, instead 6 on anterior body chaetigers and 7 on posterior ones, as in L. megaoculata sp. nov.. In addition, L. bermudensis has all uncinial teeth of similar size, while in L. megaoculata sp. nov., considerable differences occur (Figs 4 D – G; 6 E – I). Finally, L. megaoculata sp. nov., shares some characteristics with L. armata sp. nov., also described in the present paper, as discussed in the Remarks of the description of that species (see below).	en	Carrerette, Orlemir, Nogueira, João Miguel De Matos (2015): The genus Loimia Malmgren, 1866 (Annelida: Terebellidae) off the Brazilian coast, with description of three new species and notes on some morphological characters of the genus.

03D03123FFD4BF10D0D8498DFB6CEB8F.taxon	discussion	Remarks. Five other species of Loimia share with L. armata sp. nov., the presence of mid-ventral shields until segment 12, L. bandera, L. batilla, L. bermudensis, L. medusa, and L. megaoculata. Of these, L. bandera, L. batilla, L. medusa and L. megaoculata have the number of uncinial teeth similar to L. armata sp. nov. (see Table 2), however none of them have either uncini with more than 6 teeth, as those of posterior segments of L. armata sp. nov., or, except for L. megaoculata, variation on the number of uncinial teeth within tori, as occurs in L. armata sp. nov. As described above, L. megaoculata differs from L. armata sp. nov., in the morphology of the lobes of the anterior segments and in having large eyespots at the base of prostomium. In addition to similar number of ventral shields, L. bandera shares with L. armata sp. nov., a similar V-shaped structure of the distal part of prostomium and the presence of genital papillae on segments 6 – 8. On the other hand, L. bandera differs from L. armata sp. nov., in having shorter uncinial teeth, with little difference in size along the row, while in L. armata sp. nov., uncinial teeth are longer and they vary in size along the row. In addition, the lobes of segment 1 of L. bandera originate dorso-laterally, at level of first pair of branchiae, while in L. armata sp. nov., TABLE 3.

Loimi batilla is very similar to L. bandera, in all characters discussed above, thus it also differs from L. armata sp. nov., in the same features (see Table 2). Loimia medusa differs from L. armata sp. nov., in having eyespots present laterally at basal part of prostomium, and uncini with 4 – 5 teeth (Fig. 2 C, G – H), while in L. armata sp. nov., eyespots are absent and the uncini have 5 – 8 teeth, depending on body region (Tables 2 and 3). In addition, L. medusa has lobes of segment 1 originating dorso-laterally, aligned with the notopodia of segment 4 (Fig. 1 D, J), with oblique dorsal edges and distally rounded, only reaching around half length of the upper lip (Fig. 1 D); and lobes of segment 3 rounded, with narrow base, extending from ventral to dorsal edges of neuropodia, separate from fused mid-ventral shield of segments 2 – 3, and also with expanded dorsal edge distally, reaching beyond bases of branchiae of segment 3 (Fig. 1 D, J). On the other hand, L. armata sp. nov., has lobes originating ventro-laterally, with straight dorsal margin aligned with dorsal edge of neuropodia, lobes high, distally straight, almost reaching tip of upper lip (Figs 7 A – G; 9 A – C); segment 3 with lobes of nearly the same size as those of segment 1, larger than those of L. medusa, and oblique, originating from both anterior and posterior margins of segment 3, aligned to bases of notopodia of segment 4, terminating ventrally at each superior corner of partially fused mid-ventral shield of segments 2 – 4.	en	Carrerette, Orlemir, Nogueira, João Miguel De Matos (2015): The genus Loimia Malmgren, 1866 (Annelida: Terebellidae) off the Brazilian coast, with description of three new species and notes on some morphological characters of the genus.

03D03123FFCEBF18D0D84E19FBCAE9CF.taxon	discussion	Remarks. Three species of Loimia resemble L. brasiliensis sp. nov., in having uncini with 5 – 6 teeth, L. bandera, L. batilla and L. medusa (see Table 2). However, all these species have mid-ventral shields extending to segment 12, while in L. brasiliensis sp. nov., they continue to segment 14 – 15. In addition, L. bandera and L. batilla differ from L. brasiliensis sp. nov., by having distal part of prostomium as V-shaped crest, in not having eyespots at basal part of prostomium, in having lobes of segment 1 extending dorsally, originating at level of first pair of branchiae, and uncini with short teeth, all about same size.
