Tullbergia schaefferi n.sp.
Figs. 10-15 .

Amongst Dr Bagnall's slides were two of a species labelled T. schaefferi Bagn., the description of which I cannot trace in the literature. These slides are labelled "Potonga Bay, (L. Harrison), VI, 14, Australia" and "Lindfield (L. Harrison) VII, 14, Australia" respectively, and apparently the species has never been described. Accordingly I am describing it now under Bagnall's original manuscript name. It is most similar to T. australica Womersley differing from that species in the long whiplike terminal bristle to the unguiculus of the fore and middle feet and in the sense organs of Ants III and IV.

Both specimens had been badly mounted and squashed but nevertheless all taxonomic details were still remarkably clear enabling the preparation of a reasonably full description and drawing.

Colour: apparently white.

Clothing: sparse of short simple setae longer posteriorly.

Body: length 0.5 mm. Antennae with the segments indistinctly separated; Ant IV with apical knob, and five large stout bent sense rods. There are numerous long setae associated with these sense rods while the setae on the opposite surface are short. The three sense rods of SO Ant III are fully exposed, approximately in line, with a pair of short sense clubs protected by very low chitinous ridges lying between two of the sense rods; the whole with five guard setae (Fig. 12). There is a transverse band of long setae around Ant III just below the apex. PAO with 64-68 tubercles arranged in two parallel rows, but not necessarily with the tubercles exactly opposite one another; each tubercle with a distinct basal socket; the distal foliaceous lobes irregular in outline and sometimes overlapping (Fig. 14). Pseudocelli present but impossible to tabulate on these damaged specimens. Mandible normal with large molar area and head bearing four teeth, three being large and one small. Maxilla head with large base bearing two lobes, one of which carries two large curved teeth and a smaller projection, the other tooth large and curved. There are two serrated shafts as shown in Fig. 13.

Anal spines stout, curved, on short papillae; the spines about half as long as the claws of the hind feet, and guarded by three anterior and three posterior setae each in transverse rows (Fig. 10).

Legs: claws as shown in Fig. 11, without any teeth, basally finely granulate: unguiculus bulbous and finely granulate basally, with a narrow outer lamella and the shaft projected as a long whiplike bristle overreaching the claw tip on the front feet, about reaching the tip on the middle feet and somewhat shorter on the hind feet. A moderately long basal seta to each side of claw.

Holotype (Potonga Bay specimen) and paratype (Lindfield specimen) mounted on slides in Bagnall collection, in British Museum (Natural History), London.
