Holotype a complete (branchial crown detached) female with eight thoracic and three abdominal setigers. Branchial crown length 1.11 mm, remainder of body 3.25 mm long, maximum width 0.17 mm. Body very slender, slightly tapering posteriorly (®gure 1A). Branchial crown with three pairs of radioles, distal ends ®lamentous, same width as pinnules. Dorsalmost radioles with two pairs of pinnules, median and ventralmost radioles with three to four pairs; all pinnules terminate at about same height, slightly shorter than tips of radioles. Dorsal lips erect, three times longer than wide, distally rounded (®gure 1B). Ventral lips and ventral ®lamentous appendages absent. Dorsal margins of branchial lobes not fused to one another. Branchial hearts present. Anterior peristomial ring collar as a low ridge (®gure 1A), narrowly separated mid-dorsally; dorsolateral collar margins as small lobes partially overlapping mid-dorsal medial lobe (®gure 2A). Mid-dorsal medial</p> <p>1. Ventral margins of branchial lobes: (0) as narrow shelf-like processes; (1) as ventral ®lamentous appendages (i.e. vascularized and unbranched).</p> <p>2. Branchial lobes adjacent to dorsalmost radioles: (0) as dorsal lips; (1) as even shelf continuous with ventral branchial lobe margins.</p> <p>3. Branchial crown: (0) located over entire anterior end; (1) shifted dorsally.</p> <p>4. Anterior peristomial ring: (0) at least as wide as long; (1) distinctly longer than wide.</p> <p>lobe distally rounded, extending slightly above collar. Annulation between collar and anterior peristomial ring not visible. Anterior peristomial ring distinctly longer than wide, about six times longer than posterior peristomial ring. Annulation between rings visible ventrally and laterally (®gure 2A, B). Mid-dorsum of anterior peristomial ring with wide, shallow groove extending from mid-dorsal collar separation to posterior peristomial ring (®gures 1A, 2A). Ventral surface of anterior peristomial ring appears swollen and glandular (®gure 2B). Pair of crescentic to round black eyes just posterior to collar. Setiger 1 about one-half length of anterior peristomial ring, wider than long; setigers 2±3 each about same length as setiger 1 or slightly longer; setigers 4±8 successively longer than setiger 3, with setiger 8 about four times longer than setiger 1. Setiger 9 slightly longer than setiger 8, with setigers 10±11 each successively shorter than 9. Pygidium about same length as setiger 11, posterior margin slightly tapered, rounded. Pair of round, black pygidial eyes (®gure 1A). Superior thoracic notosetae elongate, narrowly hooded, three to four per fascicle. Inferior thoracic notosetae in setiger 2 elongate narrowly hooded, two per fascicle; setigers 3±8 with pseudospatulate setae (®gure 1C), two per fascicle. Abdominal neuropodia of setigers 9±11 with very elongate, narrowly hooded setae, one to three per fascicle. Thoracic uncini acicular, main fang slender (®gure 1D); large tooth oOEset from mid-line of main fang present, remaining teeth behind main fang slender and slightly decreasing in size away from fang; hood present; four to ®ve uncini per fascicle in straight single rows. Abdominal uncini with six to seven rows of teeth in pro®le, three to four teeth per row (®gure 1E); manubrium about same length as dentate region, slightly expanded proximally; uncini in setigers 9±11 number 14, 20 and 10, respectively. Females with oocytes in setiger 4, males with developing sperm in setigers 4±8. Pigmentation absent on branchial crown and body wall of all specimens. Tubes composed of ®ne silt and detritus. No brooding of young observed.</p> <p>Etymology. The speci®c epithet refers to the narrow, elongate dorsal lips in the branchial crown.</p> <p>Remarks. Fabricinuda longilabrum is most similar to F. pseudopalpa Fitzhugh, 1990a in that both have dorsal lips, but lack ventral ®lamentous appendages (table 1, ®gure 1B; Fitzhugh, 1990a: ®gure 6E). The other four described species of Fabricinuda, F. limnicola (Hartman, 1951), F. bikinii (Hartman, 1954), F. trilobata (Fitzhugh, 1983) and F. pseudocollaris Fitzhugh, 1990a, lack dorsal lips and have unbranched, vascularized ventral ®lamentous appendages (Fitzhugh, 1990a: ®gures 1E, 2E, 5A, 9A, respectively). Fabricinuda longilabrum is readily distinguished from F. pseudopalpa by the following features: (1) the anterior peristomial ring is distinctly longer than wide in F. longilabrum (®gure 2), whereas in F. pseudopalpa length and width are similar (Fitzhugh, 1990a: ®gures 6A±C, 7); the demarcation of anterior and posterior peristomial rings in F. longilabrum follows that of Fitzhugh (1990a); (2) the dorsolateral collar lobes are consistently small in F. longilabrum (®gure 2A), while in F. pseudopalpa they can range from small and lobe-like to elongate and palp-like (Fitzhugh, 1990a: ®gures 6A±C, 7); and (3) the body wall of F. longilabrum lacks pigmentation, whereas in F. pseudopalpa the anterior end is light to dark brown (Fitzhugh, 1990a: 172). Cladistic relationships among Fabricinuda species are presented below.</p> <p>Fabricinuda longilabrum is only the second described species in the genus from continental shelf depths. Uebelacker (1984) identi®ed specimens as Fabriciola trilobata, subsequently moved to Fabricinuda by Fitzhugh (1990a: 170), from the eastern Gulf of Mexico at depths ranging from 10 to 189 m. Based on her description, the specimens belong to Fabricinuda, but F. trilobata was originally described from intertidal mangrove swamp habitats oOE Belize (Fitzhugh, 1983). All other described species have been found in the intertidal (F. limnicola, F. bikinii, F. trilobata, F. pseudopalpa) or very shallow subtidal (F. pseudocollaris). There is, however, an undescribed species, Fabricinuda sp., discussed below from the same habitat as F. longilabrum.</p> <p>Fabricinuda longilabrum was identi®ed as`Fabriciola sp. 3’ in the environmental study conducted by Battelle Ocean Sciences. A new species of Pseudofabriciola, P. W laris, described below co-occurs with Fabricinuda longilabrum.</p> </div>	https://treatment.plazi.org/id/EC4A5C4862532B12FE224F62C0C9D10A	Public Domain	No known copyright restrictions apply.

Pseudofabriciola australiensis (Hartmann-SchroÈder, 1981). Fitzhugh, 1990b: 2 ±3.</p> <p>Material examined. Indian Ocean, Western Australia, Shark Bay, Denham. One specimen (GWR), sta. 96, 200±300 m oOE Denham beach, south of jetty, scrapings of Laurencia from various bivalve shells on sandy bottom, depth less than 2 m, 17 April 1995, coll. G. W. Rouse.</p> <p>Additions to description. Specimen a complete, sexually mature female with eight thoracic and three abdominal setigers. Branchial crown length 1.30 mm, remainder of body 1.70 mm long, maximum width 0.20 mm. Body slender, slightly tapering anteriorly and posteriorly. Branchial crown with three pairs of radioles, distal ends ®lamentous, same width as pinnules. Radioles each with nine pairs of pinnules, all terminating at about same height as ends of radioles. Dorsal lips erect, distally rounded, distinct from dorsalmost radioles (®gure 3). Low, distally rounded, ventral lip-like process present at base of proximalmost pinnule of ventralmost radioles. Branchial hearts present. Vascularized, ventral ®lamentous appendage s present; surfaces with minute wrinkles; about one-third length of radioles and about two times wider than pinnules; narrow blood vessel originating from branchial heart extends through most of ®lament length. Dorsal margins of branchial lobes not fused to one another; lobes narrow proximally, each terminating as short, peduncle-like stalk. Ventral ®lamentous appendages light golden brown, remainder of crown lacking pigmentation; posterior peristomial ring and setigers 1±4 with diOEuse, light brown pigmentation over body surface. Oocytes present in setiger 4. Tube absent. No brooding of young.</p> <p>Remarks. In his redescription of the species, Fitzhugh (1990b) noted that the type series for Pseudofabriciola australiensis only consists of the holotype and three paratypes, all of which lack a branchial crown. The present specimen is the ®rst complete one of this species. It largely conforms to the original description of P. australiensis provided by Hartmann-SchroÈder (1981) and the redescription by Fitzhugh (1990b). The type specimens and the present specimen have an identical collar form, with a pair of dorsolateral, V-shaped notches and a mid-dorsal U-shape d notch on the collar margin, as well as the main fang of thoracic uncini having a swollen appearance (cf. Fitzhugh, 1990b: ®gure 3C). The most notable diOEerence is that the type specimens do not have body wall pigmentation, whereas the present specimen has light brown pigmentation in the anterior thorax. Without additional specimens on which to judge pigment variability, I am not certain whether this feature denotes separate species or just regional variation. The type locality is Horrocks, Western Australia, which is about 300 km south of the location where the complete specimen was collected. The present specimen of P. australiensis occurs in the same locality as P. rousei n. sp., described below.</p> <p>The presence of well-developed dorsal lips and vascularized, ventral ®lamentous appendages in Pseudofabriciola australiensis con®rms the prediction by Fitzhugh (1990b: 3, see also Fitzhugh and Simboura, 1995: 9 ±10) that these features would</p> <p>1. Dorsal lips: (0) well-developed, triangular lobe; (1) low, narrow ridge.</p> <p>2. Ventral margins of branchial lobes: (0) as vascularized, ventral ®lamentous appendages; (1) as narrow shelf-like processes.</p> <p>3. Mid-dorsal surface of collars that are entire mid-dorsally: (0) smooth; (2) longitudinally grooved.</p> <p>4. Mid-dorsal collar margin: (0) entire; (2) notched or incised.</p> <p>5. Dorsolateral collar margins: (0) entire; (1) notched or incised.</p> <p>6. Thoracic uncini main fang: (0) slender; (1) swollen.</p> <p>7. Thoracic uncini dentition: (0) series of subequal teeth above main fang; (1) large tooth above main fang.</p> <p>8. Abdominal uncini manubrium: (0) same length as dentate region; (1) 1.5 times longer than dentate region; (2) two times longer than dentate region.</p> <p>be found in this species. This prediction was based on the overall similarities of P. australiensis to P. incisura Fitzhugh, 1990b. It was on the basis of this prediction that Fitzhugh (1991a, 1991b, 1992) considered P. australiensis to have well-developed dorsal lips and ventral ®lamentous appendages for the purposes of determining cladistic relationships within the genus and between Fabriciinae genera. As well, Fitzhugh et al. (1994) and Fitzhugh and Simboura (1995) investigated possible cladistic relationships among Pseudofabriciola species based on diOEerent combinations of states for dorsal lips and ®lamentous appendages in P. australiensis. The relationship of P. australiensis to other species in the genus is presented in the cladistic analysis below.</p> <p>On the basis of general similarities (table 4), Pseudofabriciola australiensis is most similar to P. incisura and P. quasiincisura Fitzhugh, 1996. These are the only species in the genus with ventral ®lamentous appendages (e.g. ®gure 3), and the margin of the collar has a mid-dorsal U-shaped notch and a pair of dorsolateral V-shaped notches.</p> </div>	https://treatment.plazi.org/id/EC4A5C4862592B16FE374B9CC216D3A7	Public Domain	No known copyright restrictions apply.

HOLOTYPE: LACM-AHF 2005, 200 ± 300 m oOE Denham beach, south of jetty, encrusting mats of algae scraped oOE razor oyster and pearl oyster shells on sandy bottom, depth less than 2 m, 21 April 1995, coll. G. W. Rouse. PARATYPES: LACM- AHF 2006, same locality as holotype, six complete specimens and two specimens without branchial crowns.</p> <p>Description. Holotype complete (sex unknown) with eight thoracic and three abdominal setigers. Branchial crown length 1.00 mm, remainder of body 2.60 mm long, maximum width 0.25 mm. Body slender, slightly tapering posteriorly (®gure 4A). Branchial crown with three pairs of radioles, distal ends ®lamentous, same width as pinnules. Radioles with six to seven pairs of pinnules, all terminating at about same height, at about one-third total length of radioles. Dorsal lips poorly developed as low, broadly rounded shelf-like processes (®gure 4B). Ventral lips absent. Ventral ®lamentous appendages absent. Dorsal margins of branchial lobes not fused to one another; lobes very elongate, narrowing proximally to short, peduncle-like stalk (®gure 4B). Lobes slightly curved, placing crown in dorsally directed attitude (®gure 4A). Branchial hearts present. Mid-dorsal medial lobe just ventral to mouth well developed, terminating just below collar margin (®gure 4C). Anterior margin of anterior peristomial ring a well-developed, entire, membranous collar of even height all around (®gures 4A, 5). Dorsolateral collar margins with shallow, V-shaped incisions (®gure 5A); mid-dorsal collar margin entire, broadly rounded. Mid-dorsal length of collar slightly thickened, remainder of collar of even thickness. Collar about same length as anterior peristomial ring. Annulation between collar and anterior peristomial ring visible dorsally. Length of anterior peristomial ring plus collar about same length as posterior peristomial ring. Annulation between rings visible all around (®gure 5). Pair of round black eyes at posterior margin of anterior peristomial ring. Setiger 1 slightly longer than posterior peristomial ring, wider than long; setigers 2±4 each about same length as setiger 1 or slightly longer; setigers 5±8 each two to three times longer than setiger 4. Setiger 9 slightly longer than anterior thoracic setigers, with setigers 10±11 each slightly shorter than 9. Pygidium about same length as setiger 11, posterior margin slightly tapered, rounded. Pair of round, black pygidial eyes (®gure 4A). Superior thoracic notosetae elongate, narrowly hooded, three to six per fascicle. Inferior thoracic notosetae in setigers 2± 8 elongate narrowly hooded, two to three per fascicle. Abdominal neuropodia of setigers 9±11 with very elongate, narrowly hooded setae, two to three per fascicle. Thoracic uncini acicular, main fang slender (®gure 4D); teeth behind main fang slender and slightly decreasing in size away from fang; hood present; six to nine uncini per fascicle in irregular single rows. Abdominal uncini with seven to eight rows of teeth in pro®le, three to ®ve teeth per row (®gure 4E); manubrium about 1.5 times longer than dentate region, slightly expanded proximally; uncini in setigers 9±11 number 27, 28 and 18, respectively. Anus midventral, along anterior margin of pygidium. Distribution of male and female gametes not determined. Preserved specimens white, no pigmentation on crown or body wall. Tubes unknown. Brooding of young not observed.</p> <p>Etymology. It is a great honour to name this species after Dr Greg Rouse, who has made numerous contributions to sabellid systematics.</p> <p>Remarks. Pseudofabriciola rousei is most similar to P. peduncula Fitzhugh, 1996, P. so X a Fitzhugh, 1996 and P. W laris n. sp. in that the collar margin only has a single pair of dorsolateral, V-shaped notches, with no mid-dorsal notch or incision (®gure 5A; table 4). All four species also have dorsal lips as low, narrow ridges, and ventral ®lamentous appendages are absent. Within this species group, P. rousei is similar to P. so X a in that both have a medial lobe dorsal to the mouth that extends to near the collar margin (cf. ®gure 4C, Fitzhugh, 1996: ®gure 7B), whereas this lobe is very low in P. peduncula and P. W laris. Pseudofabriciola rousei diOEers from P. so X a in having a larger number of thoracic uncini, six to nine as opposed to three to four. Relative to habitat, P. rousei occurs at intertidal depths, whereas P. so X a is only known at 26 m depth in the Gulf of Mexico (Fitzhugh, 1996). The relationship of P. rousei to other species in the genus is presented in the cladistic analysis below.</p> <p>Pseudofabriciola rousei occurs at the same locality as the specimen of P. australiensis described above.</p> </div>	https://treatment.plazi.org/id/EC4A5C48625D2B15FE584BEAC2B0D3A7	Public Domain	No known copyright restrictions apply.

Total length 4.80 mm, maximum width 0.10 mm (paratype with branchial crown length of 0.50 mm and combined thorax/abdomen length of 2.50 mm). Body distinctly thread-like, uniform width throughout except for slight tapering in abdomen (®gure 6A; but see Specimen variation below). Branchial crown (in paratypes) with three pairs of radioles, distal ends elongate, ®lamentous, same width as pinnules. Dorsalmost radioles each with four pairs of pinnules, ventralmost radioles with two pairs of pinnules, all terminating at about same height as ends of radioles. Dorsal lips poorly developed (®gure 6B); low, broadly rounded, forming narrow shelf-like process; ventral lips absent. Vascularized, ventral ®lamentous appendages absent. Dorsal margins of branchial lobes not fused to one another; lobes very elongate, narrowing proximally to short, peduncle-like stalk (®gure 6B). Branchial hearts present but indistinct. Conical structure dorsal to mouth low. Anterior margin of anterior peristomial ring as well-developed, entire, membranous collar. Mid-dorsal collar margin a membranous, triangular lappet, extending well beyond lateral and ventral collar margins (®gures 6A, 7; but see Specimen variation below); lappet distinct from remainder of collar by pair of V-shaped dorsolateral incisions; posterolateral margins of lappet overlap lower lateral collar margins. Middorsal collar lappet about three times longer than remainder of collar, about same length as posterior peristomial ring; lappet surface(?) with faint, slightly concentric lines (®gure 7A, C). Lateral and ventral collar margins entire, even in height and thickness, about one-third length of posterior peristomial ring (®gure 7B, C). Annulation between collar and posterior peristomial ring only visible ventrally. Demarcation between anterior and posterior peristomial rings not visible. One pair of reddish-brown eyes in posterior peristomial ring (®gures 6A, 7A, B). All thoracic setigers longer than wide; setiger 1 about one-third longer than posterior peristomial ring; setiger 2 slightly shorter than setiger 1, with setigers 3±6 each successively longer, with setiger 8 nearly four times longer than setiger 1. Setiger 9 about twothirds length of 8, with setigers 10±11 successively shorter. Pygidium slightly longer than setiger 11, tapered posteriorly (but see Specimen variation below). Pygidial eyes poorly developed, with diOEuse, light brown pigmentation (®gure 6A, C). Superior thoracic notosetae elongate, narrowly hooded, two to three per fascicle. Inferior thoracic notosetae in setigers 2±8 also narrowly hooded but shorter, one to two per fascicle. Abdominal neurosetae very elongate, narrowly hooded, one per fascicle. Thoracic uncini acicular, main fang slender (®gure 6D); single large tooth oOEset from mid-line of main fang, teeth behind large tooth successively smaller in size; hood present; two to four uncini per fascicle, in straight rows. Abdominal uncini with seven to eight rows of teeth in pro®le, three to four teeth per row (®gure 6E); manubrium about 1.5 times longer than dentate region, slightly expanded proximally; uncini from setigers 9±11 number 12, 13 and 10, respectively. Anus midventral, along anterior margin of pygidium (®gure 6C). Distribution of male and female gametes not determined. Body wall pigmentation absent. Tubes composed of very thin, translucent inner mucoid layer covered with thin layer of ®ne silt and detritus. No brooding of young observed.</p> <p>Specimen variation. Some specimens exhibit distinct morphological variation relative to the holotype. This variation includes shape of the mid-dorsal collar lobe and lateral incisions, overall body shape, and shape of the ventrum of setiger 11.</p> <p>The mid-dorsal collar lobe ranges from distinctly triangular, as seen in the holotype (®gures 6A, 7), to broadly rounded (®gure 8). Consistent with this variation in lobe shape, the dorsolateral notches can range from narrowly V-shaped as in the holotype (®gures 7B, 8A) to broadly V-shaped (®gure 8B, C). In those specimens exhibiting a broad mid-dorsal collar lobe, faint concentric lines on the lobe (e.g. ®gure 7A, C) are absent. Correlated with the broadly rounded collar lobe condition, specimens also tend to have relatively shorter and wider bodies, suggesting that contraction inūences collar shape to some extent.</p> <p>Those specimens with a broad collar lobe and contracted body commonly have what appears to be a small raised area on the ventrum of setiger 11. Upon close inspection, this raised area actually consists of two slightly oblong elevations on either side of the faecal groove (®gure 6C).</p> <p>Etymology. The speci®c epithet refers to the thread-like body typical of most members of this species.</p> <p>Remarks. Pseudofabriciola W laris has greatest similarities to P. W lamentosa (Day, 1963), P. so X a, P. peduncula and P. rousei n. sp. in that each has the combination of an entire mid-dorsal collar margin, smooth mid-dorsal collar surface, and one pair of dorsolateral collar notches (e.g. ®gures 5A, 7, 8; table 4). With the exception of P. W lamentosa, for which dorsal lip shape is unknown (Fitzhugh, 1991b), each of these species also has dorsal lips as low, narrow ridges, but this is not unique to this group of species. One of the most consistent and diagnostic features of P. W laris is the presence of light reddish-brown to light brown peristomial and pygidial eyespots. Other species of Pseudofabriciola have black peristomial and pygidial eyespots.</p> <p>Pseudofabriciola W laris is one of the few species known to exhibit substantial morphological variation. A notable exception is the variability in P. longipyga described by Fitzhugh and Simboura (1995). Given the number of specimens of P. W laris available for study, and the range of variation in collar shape, overall dimensions of thoracic and abdominal setigers, and the ventral elevations on setiger 11, it appears that this variation can be accounted for by way of specimen contraction, either prior to or as a result of the act of specimen preservation. There appears to be su cient overlap in the variability of these features to prevent questionable identi®cation of this species.</p> <p>Pseudofabriciola W laris co-occurs with the new species, Fabricinuda longilabrum, as well as Fabricinuda sp. Most of the specimens were identi®ed as`Fabriciola sp. 1’ in the environmental study conducted by Battelle Ocean Sciences.</p> </div>	https://treatment.plazi.org/id/EC4A5C4862402B0FFE594BEAC034D58D	Public Domain	No known copyright restrictions apply.
