Type locality. Abrolhos Archpelago , Brazil , 17˚58ʹ44ʺ S, 38˚42ʹ41ʺ W. Material examined. None. Description. Based on type description. Hototype complete, 10 mm long, 0.72 mm wide, about 55 segments. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads; pads incised with slight transverse grooves, extending from segment 4. Mid-ventral groove from segment 4. Buccal tentacles of one type . Upper lip prominent medial lobe, small wing-like lateral lobes, margin of medial lobe straight; oral surface glandular and ciliated. Outer lower lip flat, shield-like, pentagonal, large and cushionlike, ridged and grooved, extending posteriorly to segment 3 ( Fig. 46a ). Notochaetigerous segments 12, extending to segment 14. Notopodia more-or-less rectangular, prechaetal lobe low, postchaetal lobe digitiform, longer than prechaetal ( Fig. 46b ). Notochaetae within a chaetiger consisting of two types , pinnate ( type description does not say if these are primary or secondary), posteriorly same form as those anteriorly; presumed secondary notochaetae in all chaetigers smooth, narrowly winged, uniformly tapered ( Fig. 46c, d ). Neurochaetae beginning on segment 12, 9–12 uncini per row throughout. Uncini with short neck and straight to convex base ( Type 1), teeth above main fang arranged in double transverse series ( MF :3:2) subrostral process present as low protuberance ( Fig. 46e ) . Nephridial papillae not visible.
