Organism information awaits expert curation
Class: Polychaeta

Body cylindrical fragile with 19 setigerous segments. No ante-anal achateous segments in specimens having 19 setigers. Head ovoid. Two nuchal grooves slightly arched and not very prominent. No eyes visible. Buccal segment is without setae. First setigerous segment with dorsal bristles as well as ventral avicular uncini. The length of segments up to 9th setiger is less than segments 9th to 14th. Parapodia are not very prominent. The dorsal bristles are of two kinds: a lancet-shaped bristle with narrow shaft and a pointed spatulate blade and a geniculate bristle vvith fine serrations at the concave side. The first serration at the proximal end being very prominent, it gives a semibifurcated appearance to the bristle. The number of lancet and geniculate bristles varies in different specimens. Ventrally all the setigerous segments have 2 to 8 uncini with very curved rostrum. The maximum niraibers occur between segments 5 and 14. Each uncini has 5 to 6 teeth and a very much recurved manubrium having a bulbous swelling on either side. The subrostral barbules are absent. Ante-anal achaetous segment absent in specimens having 19 setigers. Pygidium is broad and the anal cone projects beyond the posterior border of the pygidial segment.
