DESCRIPTION.—Mostly covered under general characteristics of Iphione. The 13 pairs of tightly imbricated elytra covering the dorsum are variable in coloration: yellowish, reddish, yellow with brownish streaks or dark lateral streaking, sometimes masked by foreign particles. The elytra are variable in shape along the body (Figures 1E,F, 4H–J, 5C). The polygonal or hexagonal areas, with secondary areolae, nearly cover the surface of the elytra, becoming smaller toward the lateral and posterior borders where several diagonal rows of larger conical spinous tubercles occupy some of the smaller areas. The larger conical tubercles have 1 to several distal spines, with shorter spines or roughened surface basally. Along the posterior border, the smaller areas are occupied by smaller spiny tubercles of variable development. Along the lateral borders, spinous papillae occur. They consist of a cylindrical column with a flexible base, with radiating spines along the column and distally with a group of long papillae. The lateral spinous papillae were extra long on the specimen from Bikini (Figure 5c).
The prostomium, anterior segments and pharynx follow the usual pattern in Iphione (Figures 1A,B; 2A–C; 3A–C; 4A–C; 5A). The anterior lateral extensions of the prostomium, forming terminal insertions for the lateral antennae, are fused basally to the medial facial tubercle and are free distally where they may be curved medially (Figure 1A) or widely separated when the pharynx is extended (Figure 3B). The median antenna is represented by a small occipital papilla hidden by the nuchal fold of segment 2 unless the fold is pulled back. On one of the specimens from Bikini Atoll, a well-developed style was present on a small papilla-like ceratophore (Figure 4A). A distinct antenna was not observed on any of the other specimens examined. The palps and tentacular cirri are about equal in length, the lateral antennae and ventral buccal cirri somewhat shorter. The paired dorsal nodules on the anterior segments are somewhat variable in shape and distribution, always a pair on segments 4 and 5 and sometimes additional pairs on more posterior segments. Delicate transverse crests or folds, extending between the dorsal tubercles, are found on segments 6 and 8 (Figures 3A,B, 4A).
The parapodia follow the general pattern of Iphione (Figures 2C–H, 4C–G). The bushy white bundles of feathery capillary notosetae extend slightly beyond the neurosetae and hide the neuropodia dorsally and anteriorly. The neurosetae of segment 2 and the lower neurosetae of segments 3 and 4 differ from the following neurosetae: they are slender, tapering to sharp tips, with a long region of close-set spinous rows (Figure 2D). The numerous copper-colored stout neurosetae have close-set spinous rows and slightly hooked bare tips (Figures 2H, 4G, 5B). The posterior end follows the general pattern in Iphione (Figure 1D).
DISTRIBUTION.—Widely distributed in tropical and subtropical regions of the Indo-Pacific, mainly intertidal and low water, associated with coral reefs.
