Diagnosis.

Cornea subglobular. Eyes reaching to end of A1 peduncle. Rostral plate cordiform, broader than long. Dorsal processes of A1 somite forming elongated triangular lobes directed anteriorly. A2 protopod with mesial and ventral papilla (Fig. 7A).

Raptorial claw dactylus with 12-13 teeth; propodus occlusal margin pectinate, proximally with 4 movable spines. Distal end of ischium armed with an anteroventrally-directed spine (Fig. 7B). Basal segment of pereiopods 1 and 2 each armed with inner and outer spines; basal segment of pereiopod 3 with outer spine only. Mandibular palp absent, five epipods present.

AS6 with ventrolateral spine anterior to uropodal articulation (Fig. 7C). Telson broader than long; dorsal surface posteriorly with one blunt subtriangular projection; lateral margins unarmed; posterior margin with a pair of movable submedian teeth and four pairs of fixed primary teeth. Margins between each primary tooth with denticle except for submedian margin, with 5-8 submedian denticles either side of midline (Fig. 7D).

Uropodal protopod with slender distal spine at inner margin above articulation of exopod. Outer margin of proximal uropodal exopod segment laterally armed with a short fixed spine; distally with4 straight movable spines directed posteriorly; medially with stiff seta. Exopod distal segment and endopod both ovate in shape (Fig. 7C, D).

Distribution.

New Caledonia through Timor Sea to northwest shelf, Australia, and now Taiwan. This is the first record of P. pardus in the northern Hemisphere.

Remarks.

According to Moosa (1991), P. pardus most closely resembles P. malayensis of the other Pullosquilla species ( Moosa 1991). Specimens collected in this study agree well with the characteristics of Pullosquilla pardus reported in Moosa (1991) and Ahyong (2001). In addition to the differences described by Moosa (1991), the outer spine of the uropodal protopod in our specimens is always longer and stronger than the inner spine, unlike that in P. malayensis , which has a shorter and slenderer outer spine ( Manning 1968).
