Multilocular disc pores numerous on both venter and dorsum; present in single to double rows on dorsal surface across posterior edges of thorax and abdominal segments I–VII, and on head; ventrally, grouped on margins of thorax and in 1 or 2 rows on posterior edges of abdominal segments, and posterior to vulva. Quinquelocular pores numerous medially on head, thorax and anterior edges of ventral abdominal segments, and posterior to vulva. Trilocular pores evenly dispersed. Discoidal pores minute, scattered. Dorsal oral collar ducts of 1 size, scattered across thorax and abdominal segments I–VII, and grouped on margins of abdominal segments V–VII.
