Diagnosis. Australotomurus morbidus sp. nov. specimens are distinguished from other species in the genus by the following characters: males with spines on antennal segment III and not antennal segment II; only ocelli H reduced; 2 + 2 broad, toothed spines distally on the manubrium; colour pattern and large size (3 mm). The only other species that are equally large, A. johanni, A. echidnus and A. womersleyi, are from southern Australia while the more northerly species, A. montanus, A. barbatus and A. immodestus, are smaller. The colour pattern is similar to A. johanni and A. womersleyi but with differences in pigment distribution on the head and antennae. Description. Adults. Colour: Background colour white with dark purple markings, in lateral view giving a blotchy appearance, dark pigments forming bands and stripes in a consistent pattern although the extent and intensity of the pigment may vary between individuals (Figs 2–4). Antennal segment Ia dark, antennal segment Ib and II with white ring basally otherwise dark, antennal segment III and IV paler but with diffuse dark pigments in distal half. Head dorsally with 2 distinct V-shaped pigment patches on vertex, otherwise diffuse pigment anteriorly and posteriorly, laterally pale and with 2 stripes below ocelli patch extending ventrally. Coxal, precoxal and extreme lateral part of thorax darkly pigmented, dorsally paler but with thin longitudinal stripe from thoracic segment 1 to abdominal segment II; legs paler below coxa but with some diffuse pigment. Abdomen pale dorsally, abdominal segment II with small midline and pair of dorsolateral patches; abdominal segment III and IV with thin anterior band, on abdominal segment III, band extending towards posterior margin medially and dorsolaterally; abdominal segment IV with semicircle of dark spots from mid position curving anteriorly, 6 to 8 spots on each side, posterior part of segment with some pigment; abdominal segment IV with median rectangular dark patch and doors-lateral patches; abdominal segment VI all darkly pigmented. Manubrium with diffuse pigment and dens pale (Figs 2–4). Length up to 2.5 mm for males and 3 mm for females, antennae longer in relation to body length in male (a little over half body length) than in female but easily damaged, many preserved specimens with incomplete antennae. Ratios: length of body plus head:antennae = 2.5: 1 females; lengths of antennal segment Ia:Ib:II:III:IV = 1:3:5:7:9 (male), 1:2:5:8:9 (females); lengths abdominal segment III:IV = 1:1.5 to 1.6. Body chaetotaxy comprised of numerous dense, thick, parallel-sided, pale brown, finely serrated, somewhat blunt macrochaetae, short, serrated, pointed mesochaetae, long, thin, finely serrated trichobothria, a few short broad spines distally on manubrium, and a smooth, fine, pointed opposite seta on each tibiotarsus (Fig. 23). Long ciliated bothriotriches on abdominal segment II, III, IV as 2, 3, 2, respectively, one fairly long bothriothrix on head posterior to eye patch and one short, erect, smooth trichobothrium-like seta (?) laterally on antennal segment Ib. Male with thick brown spine-like setae and, broad densely, blunt and finely toothed setae on antennal segment Ib (Fig. 7) and five long spines on antennal segment III (Figs 10–11), respectively. S chaetae not distinct but antennae furnished with numerous thickish, short serrated setae and shorter fine, thin, smooth setae. Cuticle finely granulate over entire body, cuticular tubercles absent. Head and antennae, antennal segment IV indistinctly annulated, with simple apical bulb, pin seta three or twopronged (Fig. 6); all setae short and finely serrated but on more basal antennal segments becoming longer. Antennal segment III with tendency for subdivision of basal third and angled at this point, at this position 5 long, strong macrochaetae arranged in half whorl (Figs 10–11); distal external antennal segment Antennal segment III organ composed of two thick s chaetae bent inwards surrounded by three smaller s chaetae, two dorsal and one ventral(Fig. 9); antennal segment I with ventrolateral field of about 40 to 50 short finely and densely ciliated setae, each elongated and lozenge-shaped with a blunt, bare tip (Fig. 7) in the central region, and pointed at exterior part of this field; line of about 10 fine short setae within antennal segment II field. Anterior lateral margin of head of males without field of spines or dense, strong mesochaetae; 4 preclypeal setae; head chaetotaxy as in Figure 16; anterior margin of labrum with 4 round, broad, upturned papillae and 5, 5, 4 smooth setae arranged from posterior to anterior in regular arrangement, posterior row slightly longer than others (Fig. 13). Ocelli 8 + 8, only H indistinctly reduced; simple round postantennal organ present (Fig. 5). Maxillary palp with 3 sublobal hairs, simple (Fig. 15). Posterior labial row with supernumerary ciliated setae; labial palp with 5 tubercles, each supplied with up to five spines, E with smooth, curved external seta; 4 proximal setae. Mandible with three to five teeth and large grinding mandibular plate (Fig. 12). Maxilla with lamella I very finely toothed, narrow and slightly longer than 3 teeth, two other lamellae also finely toothed but broad and shorter; three of them fairly broad. Hypopharynx with finely toothed internal margin. Ventral head setae numerous, all short and finely toothed. Thorax and legs: macrochaeta distribution on thorax as in Fig. 16 (Table 3); precoxa with some macrochaetae (e. g. Prcx1 with 4, Prcx2 with 5); trochanteral organ with up to 25 short fine, pointed setae, 4 to 6 longer spine-like setae (Fig. 25); empodial appendage with small, inconspicuous external tooth, length
