| Summary: | PULVINARIA GLACIALIS Gertsson & Hodgson spec. nov (Fig. 5) (Described from 6 adult females in fair to good condition, 2 split into separate dorsums and venters) Unmounted material: not seen and no details available. Mounted material: quite large, 1.8–3.4 mm long and 1.3–3.3 mm wide, more or less oval but slightly more pointed at anterior end; symmetrical and rather flat. Stigmatic clefts absent; anal cleft about 1 / 5 – 1 / 6 th total body length. Dorsum: derm lightly sclerotised at maturity, with a series of more heavily sclerotised small areas of irregular shape, arranged more or less segmentally, most abundant near margin, becoming less frequent medially. Dorsal setae extremely scarce, possibly even absent on some specimens; when present, rather spinose, very short, only about as long as width of basal socket. Dorsal pores of 3types: (i) a small microductule with a moderately long inner ductule possibly without a glandular end: throughout, in a small areolation; (ii) a small simple pore, slightly larger than dorsal microductule: possibly present sparsely throughout, and (iii) a small group of preopercular pores anterior to anal plates: each pore closed, roundly oval, probably flat, in a small areolation; few, less than 10. Cribriform plates, dorsal tubercles, and pocketlike tubercles absent. Dorsal tubular ducts small, each with outer ductule about 5–7 µm long, inner ductule 11–13 µm long, with a small glandular end; frequent throughout. Anal plates probably each approximately triangular, 119– 133 µm long and 55–65 µm wide; each with 3 setae, all close to apex and each about 20 µm long, plus a thinner, subapical seta ventrally, perhaps about 12 µm long. Anogenital fold with 2 pairs of setae along anterior margin, each outer seta strong, 50–55 µm long, each inner seta weaker and shorter; lateral margins each with 3 setae; anal ring with six long setae, each about 150–160 µm long. Anal cleft fairly broad, without marginal setae along margins. Margin: marginal setae stoutly setose, sharply pointed, ... |
