Genus Deuterosinella nov.

Pigmented species of similar facies to Sinella but without the ocelli reduced, there being eight to each side. Scales absent. Tibiotarsus on inner surface, with at least one row of stiff, stout, plain setae. Other setae ciliated. Claw with large inner wing-like basal tooth. Tenent hairs present but weak. Genotype the following species.

Deuterosinella fusca sp. nov. Plate 42, figs. 44–47.

Colour: A ground colour of bluish-white overlaid with coarsely-granular bright orange-brown pigment. There are occasional depigmented spots and streaks, especially on Abd. IV. Abd. VI free of pigment. Legs bluish-white with dark brown or dark blue granulate pigment bands. Antennae dark blue, granular, but lighter towards the apex. Manubrium dark brown; dens without pigment. Ocelli on irregular black fields.

Clothing: Heavily clothed with short ciliated setae and numerous longer flexed setae, the latter especially along the dorsal surface and at apex of mesotergum. Setae of legs and furcula ciliated except for a double row of longer, stout, plain setae on inner margin of tibiotarsus.

Body: Length up to 2 mm. Antennae twice as long as head, the four segments related as 5:7:6:10. Ant. IV with apical sensory bristle. Ocelli eight to each side; the anterior outer ocellus very large, the sub-posterior inner and sub-posterior outer ocelli each smaller than the remaining four, which are medium-sized and equal. Mesotergum completely overlies prothorax. Abd. IV five times as long as Abd. III.

Legs: Claw with large inner, pointed, basal, wing-like tooth at one-third down with a smaller sharply-pointed normal tooth alongside it. A further prominent inner tooth at two-thirds. A pair of outer

lateral teeth, one to each side, at one-quarter down, and between them a single sharp-pointed central tooth. Empodial appendage lanceolate, two-thirds as long as the claw, with outer basal tooth. A single weak clavate tenent hair, about half as long as the claw, to each foot.

Furcula: Reaching forward to the ventral tube. Manubrium to mucrodens as 15:22. Mucro bidentate with basal spine, the two teeth equal. Uncorrugated portion of dens three times as long as mucro. Mucro surrounded but not over-reached by ciliated setae.

Locality: Taken from wood samples in the timber bin, Forestry Department, Wellington, the samples having come from Days Bay (Coll. D. Hunt).
