Telson cleft to 30 % of its length; outer tooth of each lobe overreaching medial tooth; inter-teeth spine broken off or damaged at both sides but probably barely reaching tip of medial tooth.</p><p>Etymology.</p><p>The name scylla is a reference to the Liljeborgia species described by Cedric d’Udekem d’Acoz and Wim Vader: Liljeborgia charybdis d’Udekem d’Acoz &amp; Vader, 2009 . There is a well-known idiom - to choose between Scylla and Charybdis which means “ to choose the lesser of two evils ” and we think that the genus Liljeborgia would be incomplete with only a “ Charybdis ” and no “ Scylla ”. Scylla, like Charybdis, is a sea monster from Greek mythology that lives by a rock in the strait between Sicily and Italy.</p><p>Remarks.</p><p>The new species belongs to the subgenus Lilljeborgiella (d’Udekem d’Acoz 2010 a): several spines are present on the dorsomedial margin of the peduncle of uropod 1; some or all of the setae on the anterior margin of article three of the maxilliped palp form groups or pairs, and the palp of article one possesses distal outer setae; the setae on the posterior border of the propodus of pereopods 3 and 4 are rather long and the basis of the pereopods 5–7 is not broad.</p><p>Liljeborgia scylla sp. nov. is morphologically very similar to the abyssal amphipod species L. holthuisi but can be clearly distinguished from it (Table 1). The most significant difference between the two species is the stoutness of the basis of pereopod 7. The basis is significantly narrower in L. scylla than in L. holthuisi: ~ 3.8 × as long as wide in L. scylla sp. nov. and 2.58 × as long as wide in L. holthuisi . The new species has a middorsal tooth on pleonites 1–3, but in L. holthuisi, these teeth are followed by a rounded edge. The urosomite 1 has a distinct middorsal tooth in L. scylla sp. nov. and no carina, while the urosomite 1 has a middorsal carina with two very small teeth on each side in L. holthuisi . The gnathopod 2 of L. scylla sp. nov. has a distinctive deep notch on the palmar margin. Liljeborgia holthuisi also has a similar but smaller protrusion in the same position as in L. scylla sp. nov. The original description of L. holthuisi is based on a single male specimen of 10.5 mm length. By examining more individuals of these two species, we may reveal whether the palmar notch is a sexually dimorphic character and whether there is ontogenetic variation. Liljeborgia scylla sp. nov. and L. holthuisi also share their occurrence in the abyssal waters of the Pacific Ocean. Liljeborgia holthuisi was collected at depths of 5825–5841 m in the Peru-Chile Trench (d’Udekem d’Acoz 2010 b). The new species was collected ~ 4500 km away in the Clarion-Clipperton Zone at a depth of 4137 m.</p><p>The species L. cota J. L. Barnard, 1962 is also similar in having a shallow cleft of the telson (34 %). The gnathopod 2 in L. cota also has a very similar protrusion and notch that is more prominent in juvenile males, while older males have a smooth palm. Additionally, the gnathopod 2 of L. cota has a dentate dactylus, compared to the smooth dactylus of L. scylla sp. nov. While both species inhabit the Northeast Pacific Ocean, their depth distributions differ, with L. cota found at shallower depths (366–2000 m) in South California (Barnard 1962, 1967, 1971). These two species can also be differentiated by the posteroventral corner of pleonites 1–3, which is rounded in the new species, whereas L. cota bears a tooth. The bases of pereopods 5–7 are also narrower in L. scylla sp. nov.</p><p>There are two other species that have similar protrusion-like structures on the gnathopod 2 of males. Liljeborgia quadridentata Schellenberg, 1931 and L. quinquedentata Schellenberg, 1931; both species have multiple tooth-like protrusions on the palm. It has also been observed that L. quinquedentata has larger teeth in juveniles than in adults (d’Udekem d’Acoz 2008).</p><p>Distribution.</p><p>Only known from the Clarion-Clipperton Zone, at 4223 m depth.</p><p>Molecular data.</p><p>Sequence data for the holotype of Liljeborgia scylla sp. nov. is deposited in GenBank under accession number PQ 734561. The species has also received a Barcode Index Number from Barcode of Life Data Systems: BOLD: AEB 5438 (https://doi.org/10.5883/BOLD:AEB5438).</p></div>	https://treatment.plazi.org/id/6541E37BEE6C58B1ABA2D88ACB9CAAA7	Public Domain	No known copyright restrictions apply.

It is in honour of the usage of this word by Cedric d’Udekem d’Acoz in his 2008 Liljeborgia paper; a word that we were unfamiliar with, just as we were with this new species.</p><p>Remarks.</p><p>Liljeborgia sibylline sp. nov. belongs to the subgenus Lilljeborgiella (d’Udekem d’Acoz 2010 a) . The peduncle of uropod 1 has several spines along the dorsomedial margin. Groups of setae are present on the anterior margin of maxilliped palp article three. The posterior border of the propodi of pereopods 3 and 4 have long setae, and the bases of the pereopods 5–7 are narrow. Although the holotype specimen does not appear to possess the Lilljeborgiella characteristic distal outer setae on the first article of the maxilliped palp, there are four long setae present on article 1 of the mature female paratype NHMUK 2025.40. It is possible that the smaller holotype specimen is damaged or these setae were not visible in the slide preparation.</p><p>The new species is morphologically most similar to Liljeborgia holthuisi, as is L. scylla sp. nov. (Table 1). The main difference between these species is the extremely narrow basis of pereopod 7 in L. sibylline sp. nov. (length 4.4 × width in L. sibylline sp. nov. and 2.58 × in L. holthuisi). The pleonites 1–3 have a distinct mid-dorsal tooth in the new species, while the tooth in L. holthuisi is much smaller and followed by a rounded edge. Liljeborgia sibylline sp. nov. has a single larger distinct middorsal teeth on urosomites 1 and 2, while L. holthuisi has a middorsal carina with two very small teeth. The small protrusion on the gnathopod 2 of L. holthuisi is absent in L. sibylline sp. nov.</p><p>Both species were collected from the deep sea, L. sibylline sp. nov. was found at depths of 4107–4287 m, while L. holthuisi was collected at even greater depths of 5825–5841 m (d’Udekem d’Acoz, 2010 b). Even though both species were collected at abyssal depths in the Pacific Ocean, their collection sites are separated by more than 4500 km.</p><p>Another species that shares characteristics with L. sibylline sp. nov. is L. cota . Its telson is cleft at 34 % of its length, compared to the even smaller cleft telson of L. sibylline sp. nov. that is cleft only 18 % of its length. Both species originate from the Pacific Ocean, but differ in their depth distribution, with L. sibylline sp. nov. found at 4107 m depth, while L. cota was collected at 366–2000 m (J. L. Barnard, 1962, 1967, 1971). The main difference between these two species is the posteroventral corner of pleonites 1–3, which is rounded in the new species, whereas L. cota bears a tooth. The bases of pereopods 5–7 are also more narrow in L. sibylline sp. nov.</p><p>Distribution.</p><p>Known only from the Clarion-Clipperton Zone, 4107–4396 m depth.</p><p>Molecular data.</p><p>Sequence data for the holotype of Liljeborgia sibylline sp. nov. is deposited in GenBank under accession number PQ 734720.
