Epigodromia sp. MoV5473.— Poore et al., 2008: 37, photo and caption. Material examined. Western Australia. NMV J55609 , off Albany, 35°33’S 118°34’E, 212–213 m, coll. R.S. Wilson, beam trawl, 23-11-2005: 4 females 4.2 × 3.8 mm, 4.3 × 3.9 mm, 4.0 × 4.1 mm, 5.0 × 4.5 mm, 5.2 × 4.6 mm ; NMV J556094 , off Karatha, 20°20’S 115°14’E, 100 m, Sherman sled, 11-6-2007: male 3.9 × 3.5 mm .

Diagnosis. Carapace sub-quadrangular, longer than wide, surface minutely granulate, rostrum tridentate, median tooth very small, lateral teeth large flattened; anterolateral margin convex, armed with 3 closely spaced blunt teeth, branchial notch distinct, no posterolateral tooth. Chelipeds and walking legs granulate and tubercular. P4–5 not tuberculate, sub-dorsal and sub-chelate. (See McLay 2002 for full description)

Remarks. Foredromia rostrata has only been recorded from Singapore and nearby Indonesia in shallow water. The new records from northern and southern Western Australia reported here greatly extend the depth range from 38 m down to more than 200 m. These four small specimens are smaller than the largest known (male 6.0 × 6.2 mm) ( McLay 2002).

Distribution. Previously reported from the southern islands of Singapore and Indonesia (5°48’S 106°12.5’E); 5– 38 m.
