Key to species of Arabella View in CoL recorded from the Australian coast*:
1 Ventralmost chaeta in median and posterior chaetigers tapering abruptly to guards ( Fig. 3 View FIGURE 3 L). Subgenus Cenothrix ......... 2
– Ventralmost chaeta in median and posterior chaetigers tapering gradually to guards ( Fig. 2 View FIGURE 2 E). Subgenus Arabella View in CoL ......... 3
2. (1) Chaetae robust in median and posterior chaetigers ( Fig. 4 View FIGURE 4. A – E J–K, 6B). MxI robust or gracile distally falcate MxV with two teeth ( Fig. 4 View FIGURE 4. A – E H)............................................................................ A. (C.) robusta View in CoL n. sp.
– Chaetae not robust in median and posterior chaetigers ( Fig. 3 View FIGURE 3 I, J). MxI and MxII polymorphic. MxI robust dentate or gracile
distally falcate ( Fig. 4B, C View FIGURE 4. A – E ). MxV single tooth................................... A. (C.) mutans ( Chamberlin, 1919) View in CoL 3. (1) MxI gracile, basally dentate and distally falcate on both sides, right bifid ( Fig. 1 View FIGURE 1 J, L). MxII long on both sides ( Fig. 1 View FIGURE 1 I, K). Conspicuous ventral pads surrounding nephridiopores ( Fig. 1 View FIGURE 1 N)................................ A. (A.) pulvinata View in CoL n. sp.
– Left MxI robust, MxII short. Right MI gracile, MxII long...................................................... 4
4. (3) Posterior post-chaetal lobe longer than chaetae..................................... A. (A.) longipedata Monro, 1931 View in CoL
– Posterior post-chaetal lobe shorter than chaetae........................................................................... A. (A.) iricolor ( Montagu, 1804) View in CoL - probably, a complex of species, as it is currently recognized ( Colbath 1989b).
