Mandibular palp small, uniramous
; basis unarmed; endopod 1-segmented with 1 lateral and 8 distal setae.
and cylindrical, each with three types of chaetae: 1) long, slender lyrate chaeta with small median tooth, 2) bifid chaeta, 3) short and wider chaetae with notched apex.
Later, embryos will show biramous antennae, while antennules become uniramous
and all are same in shape and size.
All the parapodia are uniramous
. Parapodium in the anterior segments has a short, rounded prechaetal lobe and digitiform postchaetal lobe.
More posterior parapodia are uniramous
, with small dorsal and ventral cirri.
First or first few anteriormost setigers generally uniramous
, biramous thereafter with inconspicuous parapodial lobes.
Sex was determined by the presence of biramous pleopods in females and uniramous
pleopods in males (Morgan 1980).
Pedipalpal femur, fv1 aspect, (0) bifid (Lawrence 1931:fig.15d); (1) uniramous
(Maury & Roig-Alsina 1985:figs.
Antennule (Figure 2a): Uniramous
, unsegmented, longer than antenna, ending in a short spine, 3 long aesthetascs and 2 simple setae.
First pleopods uniramous
, barely reaching caudal margin of annulus when abdomen flexed.
; two terminal setae and four lateroventral setae.
