Body long, vermiform. Prostomium oval, flattened, with two slightly raised longitudinal, parallel ridges diverging anteriorly. Frontal horns present at the anterior end. Proboscis glandular without any armature. No visible eyes. The palps are extremely long with a median longitudinal groove, two rows of papillae being arranged on either side of the groove. The inner row of papillae are shorter than the outer. Body consists of two distinct regions, an anterior region of nine setigers carrying simple, pointed, bilimbate capillary setae and a posterior region of many segments carrying simple hooded hooks. The ninth setiger, which is smaller than the preceding and succeeding segments, carries only bilimbate capillary setae, modified setae with distal expanded tips being absent. The notopodia and neuropodia of first nine setigers carry bilimbate capillary bristles. The simple hooded hooks which aretridentate first appear on the tenth setiger.
