Cerarii numbering 7 pairs, 4 on head (C 1 –C 4), and 3 on last 3 abdominal segments (C 16 –C 18). Anal lobe cerarii each with a pair of lanceolate setae, and 4 or 5 trilocular pores. Anterior cerarii with 2 small lanceolate setae and 2 or 3 trilocular pores. Preocular cerarii (C 3) with 3 lanceolate setae. Circulus absent. Ostioles well developed. Dorsal multilocular disc pores present across posterior edges of abdominal segments V −VII, and ventrally in 2 or 3 rows across posterior edges of abdominal segments IV −VII, on anterior edge of segment VII, on margin of abdominal segment III, and posterior to vulva. Quinquelocular pores few around mouthparts. Trilocular pores present, evenly dispersed. Discoidal pores minute, scattered. Dorsal oral collar ducts of 1 size, scattered on head, thorax and abdominal segments, except segment VIII. Ventral ducts of 2 sizes: large duct as on dorsum, distributed on head, thorax and margins of abdominal segments, and small ducts present medially on posterior abdominal segments.
