More Info

Distribution	Recorded in Australia from Ashmore Reef, Timor Sea, and from the northern Great Barrier Reef to Moreton Bay, Queensland. The species occurs elsewhere in the tropical East-Indo-West-Pacific. Shares burrows with alpheid shrimps on sandy bottoms in coastal bays and estuaries.
Features	Dorsal fin VI + I, 13-14; Anal fin I, 14-15; Pectoral fin 18-20; Longitudinal scale series 77-94. Greatest body depth 5.6-6.7 in SL; pelvic fins joined by membrane, about 10% of basal part of fins covered; midline of nape, chest and base of pectoral fin without scales; caudalfin pointed, longer than head, 2.3-3.2 in SL.
Colour	Body whitish with 5-6 light brown bars, dark speckles/lighter mottling between bars; dorsal fins and upper caudal fin with red margin.
Similar Species	The similar Amblyeleotris bleekeri differs from A. rubrimarginata by the following combination of features: (1) longitudinal scale rows: 62–63 versus 77–94; (2) pelvic fin: frenum absent versus frenum present; (3) fin colouration: D2 with thin distal brown margin and no shiny spots on D2 and C versus a conspicuous red margin or rows of small red spots on D2 and C. (Chen et al., 2006)
Etymology	The specific name rubrimarginata is from the Latin rubri for 'red' and marginata for 'edge', in reference to the distinctive bright red margin on the second dorsal-fin rays.
Species Citation	Amblyeleotris rubrimarginata Mohlmann & Randall, 2002, Bull. Raffles Mus. 50(1): 216, figs 1-3, 4A. Type locality: Watsons Bay, Lizard Island, Queensland [14°40'S, 145°28'E].
