Etymology: Ogilbia: Taken from Ogilby, 1887-1915, icthiologist and zoologist (Ref. 45335); nudiceps: Named for the scale-less head; 'nudi' = naked and 'ceps' = head.
Eponymy: James Douglas Ogilby (1853–1925) was an Irish-born Australian ichthyologist and taxonomist, son of the famous zoologist William Ogilby (below). [...] (Ref. 128868), visit book page.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 63 - 72; Raggi anali molli: 49 - 56; Vertebre: 40 - 41. The species is characterized by having the following: Vertebrae 11 + 29-30 = 40-41, dorsal fin rays 63-72, anal fin rays 49-56; small eyes (1.4-2.6, x = 1.9 % SL); outer pseudoclasper broad wing-shaped with slightly expanded tip; inner pseudoclasper with two stout branches, anterior pointing forward, posterior straight, with fleshy lobe in between, penis with abrupt change
from thick base to thin tip; opercular spine with single, sharp tip, no scales on cheeks; otolith elongate, length: height ratio 2.4 (Ref. 57883).
Inhabits rocky and sandy bottoms. A 63 mm SL female specimen (USNM 375546) contained 160 embryos, 4-5 mm TL, with three short rows of small pigment spots posteriorly on the body. No eggs. A 55 mm SL female (SIO 65-185) contained about 600 eggs, 0.5 mm in diameter (Ref. 57883).
