Haptocallisoma woolgoolga ( Kilgallen & Lowry, 2015) comb. nov.

Paracallisoma woolgoolga Kilgallen & Lowry, 2015

Type material. Holotype —female, 10.0 mm, AM P.69088, north-east of Coffs Harbour, New South Wales, Australia (30°10.88'S 153°32.22'E), 1000 m, baited trap, 12–13 August 1993, Collected by P.B. Berents, R.T. Springthorpe & W. Vader, MV Cheryl Lee [NSW-877].

Paratypes —one male, 7.5 mm, AM P.69089; many specimens, 7.0– 9.3 mm, AM P.69090, with same collection details as holotype.

Remarks. Haptocallisoma woolgoolga ( Kilgallen & Lowry, 2015) is morphologically very close to other species in the genus H. spinipoda , H. abyssi , and H. lemarete sp. nov. It can be distinguished from H. spinipoda by the gnathopod 2 palm (slightly concave in H. spinipoda , straight in H. woolgoolga ); the shape of the pereopod 5 basis (evenly rounded in H. spinipoda , with a slight excavation along the posteroventral margin in H. woolgoolga ); and the shape of the epimeron 2 posteroventral corner (producing a small tooth in H. spinipoda , subquadrate in H. woolgoolga ). In addition, in H. woolgoolga the pereopod 6 basis posterior lobe is much less distinctly excavate relative to that of H. spinipoda . H. woolgoolga can be distinguished from H. abyssi by the pereopod 5 basis (broadly rounded in H. abyssi , versus slightly excavate along the posteroventral margin in H. woolgoolga ), more strongly expanded and prehensile pereopod 3 propod in H. abyssi and by characters of the telson. The pereopod 6 basis is also less strongly excavate posteriorly in H. woolgoolga . Haptocallisoma woolgoolga can be distinguished from H. lemarete sp. nov. by characters of the telson, the pereopod 5 basis lobe (straight margin and truncate posterodistal edge in H. lemarete sp. nov.), and the more strongly expanded and prehensile pereopod 3 propod in H. lemarete sp. nov. The pereopod 6 basis is also less strongly posteriorly excavate in H. woolgoolga .

Depth range. 200–1942 m.

Distribution. Australia —east of Mooloolaba, Queensland, to south of Tasmania.
