Description
Deutonymph. Idiosoma ovoid; length 750–950 µm, maximum width 525–650 µm. Sejugal furrow clearly evident. Hysteronotum only slightly longer than prodosum.
Prodorsum. About half as long (280 µm) as wide (400 µm). Prodorsal plate longer (295 µm) than wide (220 µm), extending beyond anterior edge of propodosoma, with 7–9 pairs of lanceolate setae on each side, anteriormost pair 95–100 µm long. Crista metopica linear, rod-like, 205–220 µm long, widest anteriorly, ca 10–12 µm. 2–3 pairs of lanceolate setae posterolateral to prodorsal plate (one of them laterad of eyes), each on a platelet, ca 65–75 µm long. Prodorsal lateral plate absent. Eye plates 63– 65 x 33–39 µm, diameter 25–30µm for anterior eyes and 20–25 for posterior eyes.
Hysterosomal dorsum. Hysterosoma with traces of segmentation, each with large lateral plates bearing several to numerous setae, division between C and D by evident furrow.
C row with a pair of sublateral plates each bearing 7–8 setae; other setae each on a platelet.
D row with a pair of sublateral plates each bearing three pairs of setae; lateral and medial setae each on a platelet.
E row with a pair of sublateral plates each bearing three setae; lateral and medial setae each on a platelet.
F row with a pair of sublateral plates each bearing four setae, other setae each on a platelet. H segment with two pairs of plates each bearing three pairs of setae; a few lateral and medial setae each on a platelet.
PS segment with a pair of terminal plates each bearing 5–6 setae.
Idiosomal venter. Intercoxal area of leg I with 3–4 pairs of short setae (<50 µm long; posterolateral pair the longest, 1a over 50 µm long). Intercoxal area of leg II with three pairs of setae. Intercoxal area of leg III with 3–4 pairs of setae and that of leg IV with 4–5 setae. Coxal I with 9–12 setae. Coxa II with 6–9 setae. Coxa III with 5–8 setae. Coxa IV with 6–10 setae. Opisthoventer with numerous short setiform setae similar to coxal setae. Genital opening 100 µm long; a pair of central valves each bearing 2–3 setae (25 µm long); a pair of lateral valves each bearing 1–3 setae of similar size. Eugenital setae absent. Anal opening 125–130 µm long, its valves each with 4–7 pairs of setae.
Legs. Length of legs in decreasing order: leg I> leg IV> leg III> leg II.

Palp 375–415 µm long. Palptrochanter with one smooth seta, ca 50 long. Palpfemur with seven setae. Palpgenu with eight setae. Palptibia with seven nude setae, an enlarged seta (20 µm) near base of palptarsus and a strong terminal setae (i.e. tibial claw, 32–23 µm long), ratio of tibial length excluding tibial claw and maximum width 2.2–2.4. Palptarsus with a basal solenidion (14 µm long), 3 nude setiform setae and five terminal eupathidia (20 µm long).
Etymology
Named after the collector, Chris Winks (invertebrate ecologist at Landcare Research, Auckland).
Remarks
This new species differs from the other two species by a number of differences in morphology (see table 1). The difference in the shape of prodorsal plate, for example, is not likely to be due to ontogeny as nymphs and adults of Nanotanaupodus andrei sp. nov. have similar dorsal plates.
