The maxillary ring features cones in area I, while areas II to IV contain either cones or pointed bars arranged in a comb-like series. In the areas IV, there are cones, merged cones, and pointed bars. The oral ring is characterized by cones, shield-shaped bars, or crescent-shaped bars in the areas VI, and P-bars and cones in the areas VII to VIII, with area V having or not having cones. Paragnaths in the areas VII to VIII are arranged in one or two bands.The notopodial dorsal ligules are foliose and have a pennant-like appearance in the posterior chaetigers. The presence or absence of a prechaetal notopodial lobe can vary. Neuroacicular lobes are bilobed, and a neuropodial postchaetal lobe is present, at least in the anterior chaetigers..
