Periclimenaeus View in CoL ? sp.
Material examined: 1ɗ, 1 ovig.Ψ, MAP064, ST016, 12°40.264’N 53°27.204’E, SW of Qualansiyah, NWcoast, 5–7, 3 March 1999.
Remarks: The two specimens unfortunately lack their second pereiopods but retain some first pereiopods and some ambulatory pereiopods.
The specimens appear closely related to P. nobilii and have the rostrum deep, dorsally convex and carinate proximally, slender and upturned distally, particularly in the female, reaching to the level of the distal border of the proximal antennular segment, with a dentition of 2/0 in the female and 3/0 in the male. The scaphocerite has a small distolateral tooth, not exceeding the anterior margin of the lamella.
The third ambulatory dactyl in the female is also similar to P. nobilii in that it lacks a distal accessory tooth, but a small acute proximal tooth is present. The unguis shows a characteristic distodorsal emargination that is not present in the P. nobilii holotype. It is exactly the same in both third pereiopods and so is unlikely to be due to accidental damage. The single female fourth pereiopod dactylus is similar but the ungual emargination is less marked.
The collection was noted as associated with Jocaste lucina specimens, and coming from a live Stylophora sp., presumably from an encrusting tunicate host.
