New Polygordiidae (Polychaeta) from the Australian region

Abstract: The interstitial polychaete family Polygordiidae is recorded from Australia for the first time, based on two new species: Polygordius arafura sp. nov. from continental shelf depths in the Arafura Sea, northern Australia, and Polygordius kiarama sp. nov. from the continental shelf and slope off southeastern Australia. Polygordius kiarama sp. nov., found at slope depths up to 1650 m, is the deepest record to date for the family, which has previously been recorded from intertidal habitats, shallow coastal waters … Show more

“…include P. kiarama from Australia and P. appendiculatus from the Mediterranean Sea (Tables 3 and 4). Although it cannot be determined unequivocally that the pygidial appendages of P. ijimai (Misaki, Japan) are subterminal (vs. terminal), they are described as being "filiform", which is consistent with the appearance of subterminal pygidial cirri, and thus we also consider P. ijimai as similar to the new species (Table 4) [7,10]. Polygordius jenniferae n. sp.…”

“…The trunk shows no signs of external segmentation and is reminiscent of nematodes or ribbon worms (Nemertea), though the septa of the segments can be seen internally with the appropriate lighting. The trunk, which can have 200 or more segments, terminates in a pygidium that may be either inflated or cylindrical, and in many species of Polygordius it is encircled by pygidial glands that serve an adhesive function in the sediments [10]. These glands vary in size, shape, and number between different species [7].…”

“…The trunk consists of 200 or more segments, followed by a pygidium that may be inflated or cylindrical depending on the species. The pygidium may be encircled by adhesive pygidial glands [169] that vary in size, shape, and number depending on the species (Figure 9E, [168]). Pygidial cirri may also be present, either terminally or subterminally, forming distinctive anal lobes at the tip of the pygidium.…”
