Zoobank: 594FF421-330B-4AC6-8E58-6938146A254F ( Figures 7 , 8 A­E) Material examined. Holotype male, Waihohonu River below Waihohonu Hut , Tongariro National Park , North Island , New Zealand , 39°12 ′ 32.36’’S 175°40 ′ 49.97’’E , 3­iii­1990 , leg. A. Ballot ( NMNZ ). Diagnosis. Male: Dorsum with a large unpaired plate with concave lateral margins, a smaller unpaired posterior plate and five pairs of platelets, two of these platelets without glandularia; venter with a pair of large platelets posterior to Cx­IV. Description. Male: Idiosoma papillate, dorsally 631 long and 456 wide, ventrally 706 long. Dorsum with a large unpaired anterior plate, 400 long, 278 wide, with a pair of postocularia, covering more than half the dorsum, and a smaller unpaired posterior plate, 114 long, 146 Figure 6 Australiobates solomis Cook , male. A – venter; B – palp; C – genital field, unmounted; D – ejaculatory complex. Scale bars: A, B = 100 µm, C = 50 µm. wide. Moreover, dorsum with five pairs of platelets, anterolateral platelets located lateral to anterodorsal plate and with 1­2 glandularia, and four pairs of smaller platelets, two of these without glandularia. Venter with three groups of coxae, coxal field 425 long and 498 wide, Cx­I+II fused medially. Cxgl­4 located near suture line of Cx­III/IV. Posterior to Cx­IV a pair of large platelets. Cxgl­3 close to the latter platelets but not fused. Genital field, 163 long and 156 wide, with three pairs of acetabula, gonopore 72 long. Lateral to genital field a pair of small, elongated platelets. Vgl­2 and excretory pore immediately posterior to genital field. Length of P1­5: 23, 89, 86, 111, 50. P2 and P3 with many small papillae, P4 with a large ventral projection. Length of I­leg­4­6: 119, 125, 125. Length of IV­leg­4­6: 167, 171, 147. Female: Unknown. Etymology: Named after the national park where the species was found; the name is a noun in apposition. Remarks. The only other Zelandobates species with a very large anterodorsal plate is Z. crinitus Hopkins , but this species has very large dorsal glandularia setae. Moreover, in the male the lateral margin of the unpaired anterodorsal plate is straight (concave in the new species). For a comparison with Z. occidentalis n. sp. see there.
