Comprehensive DescriptionRead full entry
The holotype female is ovigerous, and measures 8.4 mm long, 1.3 mm wide (ncluding the parapodia), with 37 segments. Paratypes range from 4.4-12.7 mm long, 0.8-1.6 mm wide (including the parapodia), and have 28-41 segments. The body is flattened ventrally, and arched dorsally. Some live specimens have a green pigment in their parapodia, while others have a pale pink colour. Alcohol preserved specimens are pink to white in colour, although some preserved females are pale green. Internal oocytes are evident through a transparent parapodial epidermis.
The prostomium is rounded and has palps. Eyes are absent. The tentacular segment is fused with the prostomium, with one pair of dorsal and ventral cirri, neuroacicula and neuropodial hooked chaetae. The foregut has a well-developed muscular region. The pygidium is rounded, and is without anal cirri.
The parapodia are subbiramous, and have dorsal and ventral cirri. The dorsal cirri have an inflated base and a tapering tip, and are twice as long as the ventral cirri. The notopodia have a single embedded acicula, but lack chaetae. The neuropodia have a single bent acicula and hooked chaetae.
The neuropodial hooks are of two types. The anterior neuropodia have simple stout hooks with recurved tips, four to seven on each parapodium. Some are anterior to the mid-body chaetae and have a single small apical tooth near the tip, and appear slightly bifid. The posterior neuropodia have thinner simple hooks with trifurcate tips, up to seven per neuropodium.
