Philinopsis falciphallus n. sp., found from the Marshall Islands to the Red Sea, is distinguished by its reddish body color, a distinct blackor maroon longitudinal line on the foot, a posterior projection on the posterior shield and a penis with a chitinous, sickle-shaped spine and numerous smaller spines. Philinopsis coronata n. sp., known only from the Philippines, is similar to P. falciphallus but dominated by yellow body color and a ventral surface of the foot with yellow and maroon spots. It has a trumpet-shaped penis with a crown of rounded tubercles on the apex and anterior and posterior zones of penial spines. Philinopsis ctenophoraphaga n. sp. is found from the Philippines, Indonesia and the Red Sea. It feeds on platyctene ctenophores, including Coeloplana meteroris. It can be distinguished by its elongate posterior lobe of the head-shield, reddish color with white spots, thinly muscularized buccal mass and simple, unarmed penis. Chelidonura mandro-roa n. sp. is characterized by its black body with orange patches lined by yellow. It has a simple penis with a cuticularized apical papilla. This species has been found from Japan, Taiwan, the Philippines, Indonesia, Madagascar and Kenya. Chelidonura alisonae n. sp. is apparently restricted to the central and eastem Pacific of the Hawai'ian Islands, Johnston Island, the Marianas Islands and Easter Island. It is similar in colorationto C. hirundinina, but has orange lines on the dorsal and lateral shields and has a broad right posterior lobe rather than an acutely pointed one. The penis is simple and unarmed. Odontoglaja mosaica n. sp., found from the Indian Ocean of Madagascar andSouth Africa, differs from O. guamensis by possessing a reticulate pattem on the notum rather than a pattem of brown spots. It also has a shorter penial papilla that is bifurcate rather than undivided one.

(Asterom.) muricatopatella sp. nov. has only cone-shaped dermal ossicles with terminal projections on radial shields, only plate-shaped dermal ossicles on oral plates, and cone-shaped dermal ossicles with relatively short terminal projections at the lateral interradial disc. A. (Asterom.) koyoae sp. nov. has both cone-shaped dermalossicles with terminal projections and plate-shaped dermal ossicles on radial shields, cone-shaped dermal ossicles with terminal projections on oral plates, and cone-shaped dermal ossicles with relatively long terminal projections on the lateral interradial disc. A taxonomic key to all four species of the subgenus A. (Asteromoana) is provided.

Mudworm is still a serious pest of cultured molluscs in Australia but, although of great concern to many, relatively little progress has been made in resolving the problem. One hundred and thirty years later the identity and life history of this pest remains unclear. The longevity of this problem in Australia is largely due to unaddressed issues of basic taxonomy. This review addresses these issues by presenting the information currently available on the Polydora-complex species in Australia, including taxonomy; history of discovery in the natural environment and in commercial aquaculture facilities; and ecological information. An updated checklist of Polydora-complex species from Australia is also included. It is hoped that by being explicit about the knowledge gaps and problems they can be addressed, ultimatelyproviding a solid taxonomic background for further research into the Polydo-ra-complex species and resolution of the mudworm problem in Australia.

The type-series was originally deposited at the Museum of Comparative Zoology at Harvard University, under the catalog numbers MCZ 27573 (128 ex.), and MCZ 69635 (97 ex.). Five specimens were subsequently transferred to University of Michigan Museum of Zoology (UMMZ 146750), and six specimens were sent to the National Museum of Natural History (USNM 120286). Carl Hubbs examined parts of the type-series and considered the syntypes to be Micropoecilia parae (Eigenmann, 1894), as inferred from label information handwritten by Hubbs in 1944 and placed inside the jars of lots MCZ 27573 and UMMZ 146750 (ex MCZ 27573). However, Hubbs did not publish anything concerning the nomenclatural status of P. amazonica. Consequently, the name Poecilia amazonica has been considered valid by several authors since Garman's description (e.g. Rosen & Bailey, 1963; Meyer, 1993; Rodriguez, 1997; Parenti etal, 1999; Lucinda, 2003; and Lucinda & Reis, 2005).
