sp. n., the segmental origin of neuropodial spines ranged from chaetigers 16 to 45, strongly size-dependent (N = 31, r = 0.81). The segmental origin of notopodial spines varied from chaetigers 24 to 69, with weak size-dependent characteristics if compared with those of neuropodial spines (N = 31, r = 0.67). The dorsal shift of branchial finalents occurred between chaetigers 30 and 78 regardless of the total number of chaetigers in the new species (N = 31, r = 0.40) (Fig. 5).

always originated in the dorsum of two consecutive chaetigers although their locations were variable: usually on chaetigers 5-6 (in 28 specimens) and occasionally 6-7 (in two specimens) or 7-8 (in four specimens) in all the 34 specimens examined. This variation appears to be somewhat related to body size because the tentacular finalents on chaetigers 7-8 occur in specimens containing more than 300 segments (almost similar to specimens with less than 300 segments on chaetigers 5-6). Further studies with a larger population and more temporal samples are needed to determine a more accurate relationship between the segmental origin of the tentacular finalents and the body size.

Both species share the following morphological features: 1) branchial finalents a single pair per segment, gradually shifting toward mid-dorsum from relatively posterior chaetigers compared to its congeners (the dorsal shift of branchial finalents occurred at about chaetiger 35 when the body with 350 segments in
