( Figs. 25E, F View Fig , 26E, F View Fig , 27L–O View Fig , 37J View Fig , 40I View Fig , 46F View Fig , 50I View Fig , 54I View Fig , 56G View Fig )

Material examined. Holotype: male (24.3 × 18.7 mm) ( NMV J63749 View Materials ), Timor Sea , Ocean Shoals Commonwealth Marine Reserve, 12°04.5’S 127°26.62’E – 12°04.53’S 127°26.62’E, 59–66 m, coll. B.A. Glasby, RV Solander, 3 October 2012 GoogleMaps . Paratypes: 1 male (26.1 × 20.1 mm) ( NMV J63196 View Materials ), same data as holotype GoogleMaps . — 1 female (27.0 × 22.5 mm) ( NMV J63751 View Materials ), Arafura Sea, 10°58.03’S 136°47.82’E, 107–108 m, coll. B.A. Glasby, CSIRO RV Southern Surveyor , 17 October 2012 GoogleMaps .

Diagnosis. Carapace covered with relatively larger rounded granules ( Fig. 25E, F View Fig ). Pseudorostral spines long, strongly diverging ( Fig. 37J View Fig ). Antorbital spine long, straight; intercalated spine strong, with convex margins, with large gaps on each side; postorbital spine long; hepatic spine short, pointed outwards; median row with 2 spines, 1 gastric, 1 cardiac; 2 small spines on posterior carapace margin ( Figs. 25E, F View Fig , 37J View Fig ). Lateral margin with 3 large spines, increasing in size towards posterior; 1 long branchial spine, curved upwards ( Fig. 25E, F View Fig ). Basal antennal article with 2 big blunt distal teeth, external margin smooth, carinated, internal margin with one proximal lobate tooth ( Fig. 40I View Fig ). Epistome with 2 low tubercles on anterior margin ( Fig. 40I View Fig ). G1 curved, distal part simple ( Fig. 27L–O View Fig ).

Etymology. The species is named after our “Aussie” friend, Gary Poore, former curator of Crustacea at Museum Victoria. Remarks. Holthuija poorei n. sp. resembles H. pauli n. sp. in many aspects, but is easily separated by possessing a distinctly more granular carapace ( Fig. 26E, F View Fig versus Fig. 25E, F View Fig ). Holthuija poorei also has relatively shorter ambulatory legs ( Fig. 25E, F View Fig versus Fig. 24F View Fig ), and the G1 is relatively more elongated and curved with the tip distinctly dilated ( Fig. 27L–D View Fig versus Fig. 27F–H View Fig ).

The material of H. poorei n. sp. was collected off northwestern Australian coast, in the Timor Sea and Arafura Sea, both at the boundary of Indonesian waters.
