Parasites

One male of (v) and one specimen of (x) have branchial bopyrid isopod parasites.

Remarks

Not previously reported from the Philippines. Recorded from Récif Amere, New Caledonia by Bruce (1991b). All the specimens have the telson with two pairs of dorsolateral spines located marginally, from barely discernible to very distinct, although all are very small. The wide range of morphological variation also present in rostral formula, hepatic spine and ambulatory propod. The rostral formula in the samples of (viii) varies from 0/0 (3 „„, 4♀♀), 2/0 (1♀), 3/0 (1 ovig. ♀), to 4/1 (3 ovig. ♀♀), 5/1 (2 „„, 2♀♀, 2 ovig. ♀♀), 5/2 (1 „) and 6–7/1– 2, most samples have the formula 7/1. The hepatic spines vary from failing to reach the anterior carapace margin to reaching the margin (most samples), to exceeding the margin by distal one-quarter of the spine (most of the samples without or with fewer rostral teeth). Because of the series variation in the rostral formula and the hepatic spines, it is difficult to identify the samples of (x) as P. amboinensis ( De Man, 1888) or P. ceratophthalmus Borradaile, 1915 . As most samples have a ventral rostral tooth, we treat the samples as P. amboinensis instead of P. ceratophthalmus temporarily until we check the type material of the two forms and more material. The wide range of variation and the diversity of host species suggest that a complex of closely related species exists possibly in association with the wide variety of host crinoids.

Distribution

Type locality: Ambon, Indonesia . Also known from Maldives, Indonesia, Australia (Western Australia, Queensland), New Caledonia, Loyalty Islands , and Marshall Islands.
