TRIONYMUS BOCHERI Gertsson & Hodgson spec. nov. (Fig. 3) (Described from 1 specimen in good condition but missing all but 1 complete leg and 1 antenna). Unmounted material . Not known. Mounted material . Elongate oval in outline, 3550 µm long and 1575 µm wide; anal lobes rounded and moderately sclerotised; antennae 8 segmented; legs relatively quite short; circulus small and round; with 2 pairs of distinct cerarii; oral rim ducts absent. Dorsum . Membranous; setae rather few and quite short, each mainly 13–25 µm long but with some on head up to 50 µm. Trilocular pores frequent and fairly evenly distributed. Simple (discoidal) pores scarce throughout; also with 1 small convex pore dorsad to each scape. Cerarii clearly present on abdominal segments VII and VIII, each with two stout spinose setae (stoutest on VIII), length of cerarian setae on VIII 16–18 µm, those on VII about 13 µm; with 9 or 10 auxiliary setae, longest about 55–60 µm. Anal lobe distinctly sclerotised, with about 20–22 trilocular pores on each sclerotised area. Ostioles membranous, each lip of posterior pair with 6–8 trilocular pores, no setae; anterior pair with no pores on anterior lips and about 5 on posterior lips, no setae. Oral rim ducts absent. Oral collar ducts of two sizes; larger ducts (each about 4 µm wide, 8 µm long, without a thin inner ductule) frequent throughout; smaller ducts (each about 1.5–2 µm wide, 6–7 µm long, with a long thin inner ductule) very scarce on abdominal segments only. Multilocular disc­pores each 10 µm wide, present as follows: VIII 2; VII 5 along posterior margin and 2 more medially; VI 1 post., 2 elsewhere; V 4 post. + 4 elsewhere, and IV 2. Anal ring 80 µm wide, with 6 setae, each about 100 µm long. Venter . Membranous, with frequent fine setae, most clearly longer than those on dorsum, each 25–65 µm long, but some on head up to 75 µm; suranal setae 50 µm long; both long anal lobe setae broken off; each anal lobe with a small sclerotisation near base of anterior seta. Trilocular pores frequent and fairly ...
