Other material. 32 males (NMV J 62326), Cliff Head, WA (29.52 °S 114.99 °E), 1 m depth, seagrass (Amphibolis antarctica) washings, June 1985 – June 1987; six males (NMV J 62327), Little Armstrong Bay, Rottnest Island, WA (31.99 °S 115.50 °E), seagrass washings, 1 m depth, 21 Jan 1996. Description. MALE. Body (Fig. 6). Observed length 1.8 –4.0 mm; body slender, about ten times longer than broad; cephalothorax frontal margin straight from eye to slight rostrum, lateral margin straight-sided for about one third distance from eye, then expanded in smooth convex curve to anterio-lateral corner of pereonite- 1, length about 1.2 times width and approximately one-sixth body length; eyes pear-shaped, about one-fifth length of cephalothorax. Pereon just over half total length; pereonite- 1 length about one-quarter width; pereonites 2 and 3 similar, about 1.5 times length of pereonite- 1, length about one-third width; pereonites 4 and 5 about 1.6 times length of pereonite- 3, length about half width; pereonite- 6 about 1.1 times length of pereonite- 3, length about one-third width. Pleonites 1–5 similar other than declining in width posteriorly with pleonite 5 four-fifths width of pleonite- 1, together one-fifth as long as body. Pleotelson about 1.2 times length of pleonite 5; posterior margin with paired long and small central setae, one or two simple setae and plumose seta posterio-laterally, one or two simple seta anterio-laterally and another near anterio-dorsal margin. Antennule (Fig. 6). Two-thirds length of body, article- 1 about ten times longer than wide, with distal seta; article- 2 about 44 % of article- 1; article- 3 about 17 % of article- 2, articles 4-11 comprising flagellum that extends about one-quarter of total ... |
