Genus Tomocerura Wahlgren, 1900.

Isotoma-like species, in which the dentes ventrally have one or more rows of strong, simple, spines. Bothriotrichia are absent. Mucro four-toothed and generally indistinctly separated from dens.

This genus has been up to the present represented by two species from South Patagonia and one from Australia. I can now add two endemic species from New Zealand.

Key to the New Zealand Species of Tomocerura.
1. Generally large yellowish species irregularly marked with violet and having row of bright red spots along dorsal surface of body. Eight ocelli to each side, two of which are small. T. rubenota sp. nov.
2. Orange-coloured species with black pigment arranged in definite posterior intersegmental bands. No red spots. Ocelli eight to each side, all large and equal. T. maruiensis sp. nov.

Tomocerura rubenota sp. nov. Plate 51, figs. 191–194.

Colour: In life, yellowish to olive green, mottled with black and with row of bright red dorsal spots. Easily recognised by its generally large size and row of red spots along dorsal surface.

Mounted specimens show ground of deep creamy-yellow with irregular violet markings all over body and, dorsally, on mesothorax, metathorax, and on Abds. III, IV, and V large irregular-shaped, bright orange-red markings. Red colour also is present on top of head, around bases of antennae, and on first antennal segment. Remaining antennal segments deep golden yellow with violet patches at joints and on tip of Ant. IV. Legs orange-red with violet patches; furcula orange-red, becoming pale yellow towards mucro.

Clothing: Of short, plain setae, some on dorsal surface of furcula ciliated, and occasional longer, plain setae. Around Abds. III to VI are several long setae irregularly and exceedingly coarsely ciliated, the cilia being very long.

Body: Length 2·2 to 5 mm. Antennae three times as long as head, four segments related as 10: 25: 25: 32. Head slightly longer than mesothorax, mesothorax and metathorax sub-equal. Ocelli eight to each side, six large and two, the posterior two, slightly smaller, situated on black pigment patches. Postantennal organ much smaller than an ocellus and oval in shape. Abd. III slightly longer than Abd. IV, as 22: 19.

Legs: Claw long and narrow with single small inner tooth at about one-third from base, and a pair of external lateral teeth at about one-third down outer edge. Claw striated on side in vicinity of teeth. Empodial appendage about two-thirds length of claw, sharply pointed with narrow inner and outer lamellae, inner one with prominent sharp tooth at its widest part. A sigle slender, non-clavate tenent hair to each foot.

Furcula: Manubrium to mucrodens as 25: 66. Dens with three rows of short stout simple spines running about half its length. Thickly-clothed with simple setae and dorsally some ciliated setae. Mucro short, with four teeth, being a prominent apical tooth, a prominent sub-apical tooth, a smaller exterior lateral tooth, and a very small dorsal sub-apical tooth. Dens annulated and corrugated.

Localities: Lake Brunner, in bush soil and leaf debris in the forest; South Westland, in the forest south of Bullock Creek, amongst leaf debris on the forest floor; Lake Ianthe, amongst leaf debris in forest; Weheka, amongst leaf debris in forest.

Tomocerura maruiensis sp. nov. Plate 51, fig. 195.

Colour: In life, orange, with dark bluish-grey head. Mounted, dark orange-brown with narrow, broken, posterior, marginal, black intersegmented bands and similar band along ventral edges of thoracic pleura. Head mottled all over with deep blue and black pigment. Furcula dark brown tapering to yellow; legs dark brown, violet distally and basally. Antennae dark brown, violet at joints and apex. Ocelli on black pigment patches.

Clothing: Sparse, of long and short, plain setae and occasional coarsely-ciliated setae.

Body: Length 4 mm. Antennae three times as long as head, four segments related as 13: 26: 21: 35. Eight large ocelli to each side. Postantennal organ very small, elliptical. Tergum of mesothorax completely covers prothorax. Abd. III slightly longer than Abd. IV as 25: 22. Ventral tube small and dome-like.

Legs: Claw with inner tooth at one-quarter, and two large exterior lateral teeth. Empodial appendage long spine-like with prominent inner tooth at about one-fifth from base. A single non-clavate tenent hair to each foot.

Furcula: Manubrium: mucrodens as 22: 52. Dens strongly annulated and corrugated with double row of short simple spines running about half its length. Mucro with four teeth:—Large apical and sub-apical teeth, the latter ribbed on inner side, a smaller exterior lateral tooth and a small exterior dorsal tooth.

Locality: Maruia Valley, in leaf debris in beech forest.
