It differs from both of the species hitherto described. The caudal rami are much longer than those of S. parvus Boxshall, 1990 and the first antenna has many more segments (8 in S. parvus), nor are the leg spines recessed (1990: figure 13D, E). This species shares the terminal armature of the first exopodite with S. humesi Murnane, 1967, II + 4, but differs again in the segmentation of the first antenna, the gross morphology of the siphon (more slender in S. humesi) and the armature of the fifth leg: 3 setae in S. humesi. The leg setae are not divided as they are in S. humsei. Family ASTEROCHERIDAE Giesbrecht Sinopontius pu net at us Boxshall, 1990 Fig. 3D-F Sinopontius punctatus Boxshall, 1990, pp. 529-533, figs 3D-F, 4, 5. A male and a female were found in a purple-black sponge collected at a depth of 5-10m at Chek Kon Tau on 8 April 1986. They were recognised by body size ( and respectively), the rounded body shape (Fig. 3D), 19- segmented first antenna of the female, the unsegmented mandibular palp and the much reduced armature of the natatory legs. This species is distinguished from S. aesthetascus Boxshall, 1990, also described from Hong Kong specimens, by the armature of the second and third exopodites: the internal margins of the terminal segments are unarmed in S. punctatus and each has a single seta in S. aesthetascus. The specimens also exhibited the major details of the pore signature pattern drawn by Boxshall (Fig. 3E). The caudal rami are long, another useful diagnostic character. The ex
