Etymology: Labrisomus: Greek, labrax, -akos = a fish, Dicentrarchus labrax+ Greek, soma = body (Ref. 45335);  conditus: From the Latin conditus = hidden, an allusion to this scaly blenny being misidentified as L.nuchipinnis by most authors who dealt with specimens from Fernando de Noronha Archipelago (Ref. 80465).

Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 18; Dorsale zachte stralen (totaal): 12; Anale stekels 2; Anale zachte stralen: 17 - 18. Labrisomus conditus sp. n. differs from its Western Atlantic congeners (Springer 1959a, Sazima et al. 2002) by the following combination of characters: nuchal cirri when depressed not reaching dorsal-fin origin, 68 to 73 lateral line scales, first and second dorsal-fin spines slightly shorter than third spine and not flexible, numerous pale dots overall (light blue in life), opercular dark spot with incomplete and diffuse broad pale margin (orange in life) (Ref. 80465). Body entirely scaly except for interpelvic space, pectoral axilla, head and opercle; scales present oncaudal and pectoral-fin bases, basal portion of whole dorsal-fin and anal-fin membranes. Numerous branched canals and pores on head, one branch from pre-opercular series extending onto upper opercle. A single well-developed row of conical slightly recurved teeth on each jaw, and an inner closeset patch of much smaller, villiform teeth. Distal teeth on upper jaw larger than proximal ones. Vomerine teeth in a “V” pattern, the apical and centralmost one at least 5 times larger than remainder, the latter arranged in 2–3 rows (Ref. 80465). Color pattern: adult males variable; body grayish or reddish brown to dark brown crossed by four darker irregular bars, sometimes with fainter and shorter ones between them, with scattered irregular pale spots (less conspicuous on dark individuals, and faint or absent in preservation) (Ref. 80465).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00399 - 0.02083), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.5   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
