Etymology: Ogilbia: Taken from Ogilby, 1887-1915, icthiologist and zoologist (Ref. 45335); boydwalkeri: Named for Dr. Boyd Walker.
Eponymy: James Douglas Ogilby (1853–1925) was an Irish-born Australian ichthyologist and taxonomist, son of the famous zoologist William Ogilby (below). [...] Professor Dr Boyd W Walker (1917–2001) The etymology says: “Named in honour of the late Dr. Boyd Walker, who studied Ogilbia for many years.” (See Walker, BW) (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 64 - 72; Anal soft rays: 49 - 54; Vertebrae: 39 - 41. The species is distinguished by the following characters: vertebrae 11 + 28-30 = 39-41, dorsal fin rays 64-72, anal fin rays 49-54; outer pseudoclasper is broad, wingshaped with single curved supporter; inner pseudoclasper with three lobes, consisting of a branched supporter, anterior branch curved and long, posterior branch short, and a thick fleshy lobe in between;
penis with no abrupt change in thickness; opercular spine with single, sharp tip in small specimens and bi- or tri-furcated in specimens > 45 mm SL; scale patch on cheeks is broad, with 8-10 vertical scale rows; otolith length: height ratio 2.2 (Ref. 57883).
Apparently lives on rocky bottoms (Ref. 57883).
