Key to Palola clades from Lizard Island

1 Peristomial cirri reach at least to or beyond anterior margin of peristomium; fairly uniform brown pigmentation dorsally.............................................................................................. Palola clade 6

– Peristomial cirri not reaching to anterior margin of anterior peristomial ring; pigmentation, if present, faint or limited to poste- rior margins of segments................................................................................ 2

2. (1) Antennae and palps smooth and blunt-tipped..................................................... Palola clade 2

– Antennae wrinkled and with a pointy tip................................................................... 3

3. (2) Anterior margins of mandibles serrated.................................................................... 4

– Anterior margins of mandibles with a smooth edge........................................................... 5

4. (3) First peristomial ring 1.5 to 2 times as long as second peristomial ring in lateral mid-line.................. Palola clade 1

– First and second peristomial rings nearly equal in length in lateral midline.............................. Palola clade 5

5. (3) Lateral antennae about 2/3 the length of the median antenna......................................... Palola clade 4

– Lateral and median antennae more similar in length to each other..................................... Palola clade 3
