FIGURE 11. Dulichiella australis ( Haswell, 1879 ) , male, 10.0 mm, AM P60600, west side of Box Head, Broken Bay, New South Wales, Australia. (After Lowry & Springthorpe, 2005 : fig. 50). Type material. Syntypes : 5 specimens , AM G5393 ; 1 specimen AM P3495 , Port Jackson , New South Wales , Australia (approx. 33°51'S 151°16'E ) . Type locality. Port Jackson , New South Wales , Australia ( 33º51'S 151º16'E ) . Additional material. Male, 10 mm , AM P60600; female, AM P60601, west side of Box Head , Broken Bay , New South Wales , Australia . Description. Based on male, 10 mm , AM P60600 and female, AM P60601. Body large. Head eyes round; lateral cephalic lobe broad, truncated, anteroventral corner with slender setae. Antenna 1 peduncular article 1 shorter than article 2, with 4 robust setae along posterior margin . Antenna 2 peduncular article 2 cone gland reaching at least to end of peduncular article 3; article 4 subequal to article 5. Mandibular palp article 1 about as long as broad, inner margin article 1 produced distally; article 2 shorter than article 3. FIGURE 12. Dulichiella australis ( Haswell, 1879 ) , male, 10.0 mm, AM P60600, female, AM P60601, west side of Box Head, Broken Bay, New South Wales, Australia. Scales represent 0.5 mm. (After Lowry & Springthorpe, 2005 figs 51, 53). Gnathopod 1 coxa anteroventral corner not produced, anterior margin straight, posteroventral corner notch present; carpus subequal in length to propodus; propodus small, linear, palm slightly convex or straight, palm defined by posterodistal corner, without posterodistal robust setae. Gnathopod 2 coxa posteroventral corner notch present; (larger) propodus distolateral crown with 3 indistinct rounded spines , palm straight, posterodistal corner produced, upturned, with dactylus fitting into corner; dactylus apically blunt; (smaller) merus with sharp posteroventral spine; palm straight, lined with robust setae, posterodistal corner with robust setae; dactylus with 4 setae on anterior margin. Pereopod 5 dactylar unguis anterior margin with accessory spine. Pereopods 6–7 carpus and propodus with bunches of long slender setae. Pereopod 6 basis posterior margin straight; dactylar unguis anterior margin with accessory spine . Pereopod 7 basis posterior margin straight. FIGURE 13. Dulichiella australis ( Haswell, 1879 ) , male, 10.0 mm, AM P60600, female, AM P60601, west side of Box Head, Broken Bay, New South Wales, Australia. Scales represent 0.5 mm. (After Lowry & Springthorpe, 2005 : fig. 52). Pleonite/urosomite dorsal spine formula (7-7-7-5-4-2) . Pleonites 1–3 with sparse dorsal setae. Epimeron 1 posteroventral corner with small acute or subacute spine. Epimeron 2 posteroventral corner acute. Epimeron 3 posteroventral margin smooth. Urosomite 1 with three dorsal spines. Urosomite 2 with two groups of 1–3 small dorsolateral robust setae. Urosomite 3 without dorsal setae, with 2 dorsal spines. Uropod 3 outer ramus very long, length about 2 x peduncle. Telson with dorsal robust setae. Female (sexually dimorphic characters). Gnathopod 2 subequal in size, similar to smaller gnathopod 2 of male; palm slightly concave; dactylus posterior margin minutely crenulate. Pereopod 7 basis expanded, posterior margin tapering distally. Habitat. Marine epibenthic, living among bryozoans, sponges, ascidians and algae in 4 to 120 m depth. Remarks. Three Indo Pacific species, Dulichiella australis , D. oahu and D. tulear , all have three spines on the distolateral crown of male gnathopod 2 and a 7-7-7-5-4/6-2 pleonite/urosomite spine formula. Duli- chiella australis differs from D. tulear in the narrower propodus of the smaller male gnathopod 2, and in the smooth posteroventral margin on epimeron 3 (minutely serrate in D. tulear ). Unfortunately the setation of pereopods 6 and 7 is not known in D. tulear . Dulichiella australis is very similar to D. oahu . The main differences between these species are antenna 1 peduncular article 1 with four robust setae in D. australis and two robust setae in D. oahu , and the pereopodal dactyli which have one accessory spine in D. australis and two accessory spines in D. oahu .
