Sac-shaped body, elongated in the oral-aboral axis, rounded both at oral and aboral ends. Body compressed in the tentacular plane. Eight meridional canals extending from the aboral region towards the mouth, directly connected with a circular canal around the mouth. No lateral diverticula observed along the meridional canals. Ctene rows located above the meridional canals, arising at the aboral region. Substomodeal and subtentacular ctene rows of almost equal length, extending for about 1/3 to half the length of the meridional canals to the oral region. Mouth wide, semicircular, extending the whole oral region, opening into a large pharynx that occupies most of the central inner part of the animal. Two opposite paragastric canals, extending from the aboral pole of the pharynx to the circular canal around the mouth at the tentacular plane. Apical organ composed of a statolith at the center of the polar fields, with unbranched aboral papillae, not longer than the statolith dome. Male gonads formed at the lateral walls of the meridional canals. No female gonads present in the specimens observed. Macrocilia arranged in a broad band along the oral portion of the pharynx.
