Nec Periclimenes toloensis ( Bruce & Coombes 1995) View in CoL : 135, 139 (list), Fig. 12 D, F.

Material. Holotype male, CL 2.5 mm, Ap Island , Tolo Channel, Hong Kong, RMNH D33231.

Remarks. The holotype specimen examined agrees with previous descriptions ( Bruce 1969, 1982b; Chace & Bruce 1993). The third maxillipeds have the ischiomeral segment fused with the basis, with the suture visible, as figured by Bruce (1982b: Fig. 17H). The ambulatory legs have the dactylo-propodal “grasping structures” less distinct, with the propodal spines arranged in 3 closely set distoventral pairs, followed by 2 single widely spaced single spines more proximally. The longest of the distoventral spines are subequal or shorter than the distal propodal depth.

Bruce & Coombes (1995) list several series of P. toloensis collected from hydroids and various other hosts from the Cobourg Peninsula, Northern Territory, Australia. They report the presence of a wide triangular median process on the fourth thoracic sternite and large setose distoventral processes on both the coxa and basis of the first pereiopods. None of these structures are present in the P. toloensis holotype ( Bruce 1982b; present review). The fourth thoracic sternite is unarmed, only indistinctly produced medially, the fifth sternite bears a low pair of transverse ridges separated by a shallow median notch; only a small setose tubercle is present distoventrally on the first pereiopod coxa, and the basis is unarmed. The holotype also differs from the Cobourg specimens by the produced lower orbital margin with an angulate tip, the medial and ventral flanges not tapering as figured by Bruce & Coombes (1995: Fig. 12D), and the hepatic spine placed distinctly more below the antennal spine level. We suggest that the Australian specimens discussed here are distinct from P. toloensis , probably closer to P. incertus Borradaile, 1915 . Both these species are regarded ( Bruce 1987; Berggren 1994) as members of the P. obscurus species group.

Color. Transparent ( Bruce 1969).

Host. Hicksonella princeps Nutting (Gorgonaria) , 10–30 m ( Bruce 1998); Lytocarpus philippinus (Kirchenpauer) (Hydroidea) ( Bruce 1981) .

Distribution. —Ap Island, Tolo Channel, Hong Kong (type locality); Tanzania, Philippines, Great Barrier Reef, Australia ( Chace & Bruce 1993).
