CHORIZOCOCCUS MULTIPORUS Gertsson & Hodgson spec. nov (Fig. 2) (Described from 2 good, well­stained specimens plus another in fair condition) Unmounted material: not known. Mounted material. Oval in outline, 1175–1250 µm long and 575–675 µm wide; anal lobes moderately developed; antennae 7 or 8 segmented; legs of normal length; circulus present; with 3 pairs of distinct cerarii; oral rim ducts present. Dorsum. Membranous, with frequent fine setae, each 7–22 µm long; setae absent medially on abdominal segment VIII. Trilocular pores relatively sparse and fairly evenly distributed. Simple (discoidal) pores possibly only present mesad to eyespots; also with 3–5 small convex pores dorsad to each scape. Cerarii clearly present on abdominal segments VI, VII, and VIII, each with two stout spinose setae (stoutest on VIII), length of cerarian setae on VIII 17–22 µm; with 11 or 12 auxiliary setae, longest about 33–40 µm; setae on segment V stouter than normal setae and set further apart than on other cerarii and without associated trilocular pores. Ostioles membranous, each lip with few trilocular pores plus 0 or 1 small setae. Oral rim ducts each 8 µm wide, present as follows (totals across segment): VIII 0; VII 5–13; VI 6–9; V 11–16; IV 10–14; III 6–10; II 5–9; I 6–12; metathorax 4–10; mesothorax 5–14; prothorax 2 or 3; head 1–7. Oral collar ducts absent. Multilocular disc­pores absent. Anal ring 70–74 µm wide, with six setae, each about 90– 107 µm long. Venter. Membranous, with frequent fine setae, each 10–25 µm long, some obviously longer than those on dorsum, with some on head 40–50 µm long; suranal setae 35–40 µm long; long anal lobe setae each 100–118 µm long. Trilocular pores relatively sparse and fairly evenly distributed. Simple (discoidal) pores not detected. Oral rim ducts present: generally 1 or 2 (occasionally 0) on lateral margins of most segments. Oral collar ducts probably of two sizes, with larger ducts located along the posterior margin of each segment and near lateral margin of abdominal segments II ...
