Notopodia and capillaries of third to fifth segments increasing gradually in size. Neuropodial uncini begin on fourth chaetiger (segment VI) and present in 12 thoracic segments. Thorax sharply subdivided into two regions. Segments of anterior region (up to thoracic chaetiger 10) approximately half as long as those of posterior region, neuropodia of anterior region large, and similar-sized, while those of posterior region become gradually smaller; the neuropodia of last thoracic unciniger is half size of first thoracic unciniger. Neuropodia of thoracic uncinigers are tori, without dorsal cirrus; neuropodia of abdominal uncinigerous are pinnules, with papillary dorsal cirrus (Fig. 2E).
