PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASfflNGTON 108(4):577-582. 1995 New genera for two polychaetes of Lepidonotinae Marian H. Pettibone Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560, U.S.A. Abstract. — Among the Lepidonotinae, two species of Lepidonotus are re-ferred to new genera: L. dictyolepis Haswell, from Australia, to Augenerilepi-donotus, and L. kumari Rullier, from Malaya, to Olgalepidonotus. As part of an on-going study on the po-lynoid polychaetes, two species that were described under Lepidonotus Leach, 1816, L. dictyolepis Haswell, 1883, from Aus-tralia, and L. kumari Rullier, 1970, from Malaya, show differences from Lepidon-otus and are referred to two new genera: Augenerilepidonotus, for the first species, and Olgalepidonotus, for the second spe-cies. The specimens examined in this report were received on loan from the Australian Museum, Sydney (AMS), through Eliza-beth Pope, Pat Hutchings, and Neville Coleman; from the Western Australian Museum, Perth, through R. W. George; and from Professor Francois Rullier, La-boratoire de Zoologie, Angers, France (LZA). Family Polynoidae Kinberg, 1856 Subfamily Lepidonotinae Willey, 1902 Augenerilepidonotus, new genus Type species. — Lepidonotus dictyolepis Haswell, 1883. Gender: masculine. Diagnosis. — Body short, flattened, sub-rectangular, with 26 segments (first achae-tous). Elytra and prominent elytrophores 12 pairs, on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23. Elytra large, oval, over-lapping, with surfaces mostly covered with chitinous irregular polygonal areas enclos-ing small secondary areolae, with some spi-nous microtubercles and lateral fringes of short, wide papillae. Dorsal cirri on non-elytrigerous segments, with bulbous cirro-phores and short styles; dorsal tubercles in-distinct. Prostomium bilobed, lepidonotoid, with 3 antennae, 2 palps, and 2 pairs of eyes; median antenna with bulbous cerato-phore in anterior notch of prostomium; lat-eral antennae inserted terminally on anterior extensions of prostomium. First or tentac-ular segment not visible dorsally; tentacu-lophores lateral to prostomium, achaetous, with 2 pairs of dorsal and ventral tentacular cirri, with bulbous upper lip and small in-distinct facial tubercle. Second segment with first pair of elytrophores, biramous parapodia, and long ventral buccal cirri. Bi-ramous parapodia with small, conical no-topodia on anterodorsal faces of larger neu-ropodia; neuropodia with subconical pre-setal lobe and shorter, rounded postsetal lobe, deeply cut dorsally and ventrally. No-tosetae numerous, slender, densely serrated, short, extending only slightly beyond tips of neuropodia, much more slender than neurosetae; few short, tapering to blunt tips and numerous, long, tapering to capillary tips. Neurosetae stout, relatively few (8-12), with few spinous rows (4-5), and curved unidentate tips. Ventral cirri short, subulate. Pygidium with anal ridge and pair of anal cirri. Nephridial papillae small, bul-bous, beginning on segment 8. Pharynx (?) not extended. Etymology. — The genus is named for Herman Augener (1927), whose descrip-tion and figures of a specimen of Lepidon-otus dictyolepis, from near the type local-
