2467EF72DC02FFE4FF1F3F96FB58FC6D.taxon	description	Description. Specimens small and threadlike. Anterior fragments examined for all sequenced specimens, ranging in length from 7 to 18 mm and from 0.6 to 1.7 mm in width; with 38 – 78 chaetigers. Branchiae only observed in one specimen (AM W. 44034) from chaetiger 62 to the end of the fragment. No ventral eyespots.

Mandibles usually protruding from mouth, thin and nearly transparent with serrated anterior margin (Fig. 2 B). Maxillae not examined. Antennae, palps and peristomial and parapodial cirri without pigment. Antennae and palps wrinkled, in preserved material, tapering and pointy tip. Median antenna reaches to chaetiger 2 or 3, lateral antennae reach to chaetiger 1 or 2 and palps reach to first or second peristomial ring. Tapering peristomial cirri reach forward to about 3 / 4 of the length of first peristomial ring. Eyes dark, oval or with ventral notch and nestled between lateral antennae and palps. Acicula brown.

2467EF72DC02FFE4FF1F3F96FB58FC6D.taxon	discussion	Remarks. Although only distantly related in the phylogenetic tree and representing different species groups, Palola Lizard Island clade 1 is morphologically most similar to clade 5. Members of both clades are thin and threadlike, almost entirely lack pigmentation and have relatively thin and transparent mandibles. They can be distinguished by the relative length of the first and second peristomial rings: in clade 1, the first peristomial ring is 1.5 to 2 times as long as the second when viewed in the midlateral line where as in clade 5 they are more similar in length. Despite the morphological similarities, COI sequences are 26.9 % divergent (Kimura- 2 - Parameter model) between clades 1 and 5. Palola Lizard Island Clade 1 falls into species group A and is the sister group to a clade with an extremely wide geographic distribution throughout the tropical Eastern and Western Pacific, referred to as clade A 1 in Schulze (2006) and Schulze & Timm (2012). The average genetic distance to this clade is only 1.9 % and the two might represent the same species, although they are reciprocally monophyletic.	en	Schulze, Anja (2015): Six genetically distinct clades of Palola (Eunicidae, Annelida) from Lizard Island, Great Barrier Reef, Australia.

2467EF72DC03FFE4FF1F3CD2FB6CF8EE.taxon	description	Description. One of the specimens (AM W. 44914) much larger (Fig. 2 D, E) than the others which are thin and threadlike (Fig. 2 F). Anterior fragments closely examined for the three sequenced specimens. The larger specimen (AM W. 44914) is 52 mm long and up to 5 mm wide with 165 chaetigers. The smaller specimens are 5 mm long and 0.7 mm wide (AM W. 44181) and 9 mm long and 1 mm wide (AM W. 44006) with 34 and 63 chaetigers, respectively. Branchiae present in AM W. 44914 from chaetiger 123 to end of fragment. No ventral eyespots. Mandibles protruding from mouth in smaller specimens; thin and almost transparent. Head and body in larger specimens with brown pigment dorsally on prostomium and posterior portions of peristomial rings and anterior chaetigers (Fig. 2 D – E). Antennae, palps and peristomial and parapodial cirri without pigment. Smaller specimens without pigmentation. Antennae and palps slightly medially inflated in larger specimen and with a blunt tip. In AM W. 44914 median antenna reaches to chaetiger 4, lateral antennae reach to chaetiger 2 and palps to first peristomial ring. Tapering peristomial cirri reach forward to first peristomial ring. Eyes dark, round with a ventral notch and nestled between lateral antennae and palps. Acicula brown. Other chaetae not examined.	en	Schulze, Anja (2015): Six genetically distinct clades of Palola (Eunicidae, Annelida) from Lizard Island, Great Barrier Reef, Australia.

2467EF72DC03FFE4FF1F3CD2FB6CF8EE.taxon	discussion	Remarks. The smaller specimens belonging to this clade are difficult to distinguish from members of clades 1 and 5 which are also largely without pigmentation. However, in clades 1 and 5 the anterior margins of the mandibles are serrated, whereas they are smooth in clades 3 and 4. The larger specimens show a distinctive pigmentation pattern with brown pigment in the posterior, dorsal portion of the peristomial rings and anterior chaetigers and distinctive shape of antennae and palps. The latter are slightly medially inflated and have blunt tips, as opposed to tapering with sharp tips as in the other clades. Palola Lizard Island Clade 2 falls into species group A and the mean genetic distance to any of the other clades in species group A is 20 % and over.	en	Schulze, Anja (2015): Six genetically distinct clades of Palola (Eunicidae, Annelida) from Lizard Island, Great Barrier Reef, Australia.

2467EF72DC03FFE6FF1F384EFBEBFF1D.taxon	discussion	Remarks. Clade 3 is morphologically very similar to clade 4. Both belong to species group A, are thin and threadlike and have faint brown dorsal pigmentation in the anterior body regions, and have mandibles with smooth anterior margins. The two can be distinguished by the relative length of their antennae. Whereas in clade 3 the median and lateral antennae are similar in length, in clade 4 the lateral antennae are only ~ 2 / 3 the length of the median antenna. The two clades differ by over 20 % in COI sequence divergence.	en	Schulze, Anja (2015): Six genetically distinct clades of Palola (Eunicidae, Annelida) from Lizard Island, Great Barrier Reef, Australia.

2467EF72DC01FFE9FF1F3AC9FECEF9DA.taxon	description	Description. Most specimens relatively large with strongly calcified mandibles protruding from mouth. Anterior fragments closely examined for all sequenced specimens, ranging in size from 11 mm to 50 mm, 1.5 – 3 mm wide; with 41 to 153 chaetigers. Dorsoventrally flattened with a deep ventral groove. Some larger fragments with branchiae, starting from chaetiger 77 (AM W. 44645) to chaetiger 98 (AM W. 43906). No ventral eyespots. Head and body pigmented, particularly dorsally, with fairly uniform brown pigment (Fig. 2 A, B). Antennae, palps and peristomial cirri without pigment. Antennae and palps wrinkled, in preserved material, tapering and pointy tip. Median antenna generally reaches to chaetiger 4, lateral antennae to chaetiger 2 or 3 and palps to posterior end of first or to second peristomial ring. Tapering peristomial cirri reach forward at least to anterior margin of first peristomial ring or beyond. Eyes dark, round with a ventral notch and nestled between lateral antennae and palps. Bases of ventral cirri strongly inflated after chaetiger 10. Chaetiger 10 with single dark acicula, single capillary chaetae and multiple compound falcigers (Fig. 4 C, D).	en	Schulze, Anja (2015): Six genetically distinct clades of Palola (Eunicidae, Annelida) from Lizard Island, Great Barrier Reef, Australia.

2467EF72DC01FFE9FF1F3AC9FECEF9DA.taxon	discussion	Remarks. This is the most morphologically distinctive of the six clades found on Lizard Island. Members of Palola clade 6 can be distinguished from the other clades by the relatively uniform dark brown pigmentation and the long peristomial cirri which often reach forward to the eyes or beyond. This clade is the most closely related to the type species of the genus, Palola viridis, but can be distinguished from it by the shorter antennae: in P. viridis, the median antenna reaches to chaetiger 10 (Fauchald 1992) and only to chaetiger 4 in Palola Lizard Island clade 6. The average genetic divergence between the two lineages is 20 % (Kimura- 2 - parameter model) for COI. Posterior ends are missing in all of the specimens, but even the longer fragments do not have ventral eyespots as reported in P. viridis.	en	Schulze, Anja (2015): Six genetically distinct clades of Palola (Eunicidae, Annelida) from Lizard Island, Great Barrier Reef, Australia.
