Six males, (NMV J 62320) Bickley Point, Rottnest Island, WA (32.00°S 115.56 °E), seagrass washings, 0.5 m depth, 10 Jan 1991. Description. MALE. Body (Fig. 10). Observed length 1.3–2.1 mm; red colouration when freshly preserved; body about eight times longer than broad; cephalothorax subrectangular, laterally slightly convex, approximately one-sixth body length; eyes very large, ovoid, about one-third length of cephalothorax.

Pleonites 1–5 similar other than declining in width posteriorly with pleonite 5 five-sixths width of pleonite- 1, together one-fifth as long as body. Pleotelson about 1.2 times length of pleonite 5; posterior margin with paired central medium-length and minute setae, posterior pair of setae (one minute) and anterior seta on each lateral margin.
