Kuwanina kiwiana sp. nov.

( Fig. 3 )

Live appearance: unknown.

Adult female only available life stage.

Description of adult female, measurements taken from 4 specimens ( Fig. 3 ).

Body elongate-oval, 0.37–0.68 mm wide, 0.51–0.9 mm long; derm membranous except dorsum of abdomen sclerotised, with deeply furrowed intersegmental lines, and abdominal intersegmental areas heavily folded and creased; derm of ventral submarginal abdomen nodulose. Eyespots not seen. Marginal setae 7.5– 10 μm long, with 1 seta on margins of each abdominal segment, apparently absent on thorax and head. Antennae unsegmented, 25–27.5 μm long, reduced to vestigial lobes lacking normal setae and pores; with 2 narrow terminal extensions which may represent a pair of fleshy setae but these not present on all specimens. Labium 40–47.5 μm long, with 5 pairs of setae discernable. Anal lobes broad; joined together as 1 contiguous lobe with a small dorsal invagination; length 50–60 μm long, total width 112.5–130 μm wide; anal lobe setae lengths (μm): LD1–LD3 each 9–10; LV 1 9–11, apical seta 30–35; suranal seta hook-shaped, 9–10 μm long. Anal ring non-cellular, ventral, oval, with 3 pairs short setae on posterior half, pointing inwards; anterior margin of ring simple. Legs represented by vestigial leg flaps; prothoracic leg a very small, rounded shape, 12–15 μm long and 20 μm wide; mesothoracic leg narrow and triangular, with a distal point, 12–14 μm long and 22– 30 μm wide; metathoracic leg broadly triangular, 22–25 μm long and 20–25 μm wide, with several pores that may be sensilla, and a minute terminal seta just 2 μm long.

Dorsum. Dorsal setae either small and spinose or abruptly needle-shaped distal to relatively broad base within a sclerotised collar, each seta 4–8 μm long, distribution in segmental rows of 8–10 setae on abdomen, very few discernable on thorax and head. Microtubular ducts with faint gland and ductule, opening into a sclerotised wide collar about same diameter as that of setal bases, with 4–8 microtubular ducts interspersed between setae on each abdominal segment, and with a total of approx. 6 microtubular ducts on each side in a submarginal line on thorax and head. Macrotubular ducts absent.

Venter. Ventral abdominal setae needle-like to finely lanceolate, 3–12 μm long, with 4–10 setae submedially plus 1 submarginal seta on each side on abdominal segments. Ventral invaginated disc pores 5-locular, 4– 5 μm wide, 6–7 μm deep, in a submarginal band from prothorax to abdominal segment IV each side, band not extending close to spiracles. Spiracles small, without a well developed apodeme; each spiracle within a large semi-circular membranous invagination; associated spiracular disc pores slightly invaginated, 5-locular, on short stalks, forming a tight bunch close to each spiracular peritreme. Mesothoracic spiracular area length 42.5–52.5 μm, width 37.5 μm; metathoracic spiracular area length 50–52.5 μm, width 37.5–45 μm. Microtubular ducts and macrotubular ducts absent. Vulva apparently situated between segment V and VI.

Comments. Diagnostic features of adult female as for genus. Noted features of embryos contained within some females were: 5-segmented antennae, 2 disc pores by each spiracle, and well developed legs, each with a very long claw.

Type material. Holotype female: NEW ZEALAND, SL, Southland, 900–1000 m, 17 May 1956, [no collector], Nothofagus menziesii : 1/ 1 F.

Paratypes: as for holotype, 3/3 FF (2 containing embryos).

Other material examined: collection data as for type material: 4/4 FF (poorly stained).

Etymology. The specific epithet kiwiana is a colloquialism for objects peculiar to the New Zealand way of life, particularly from about the time this scale was collected in the 1950s.
