All Lobianchia Species: Three or more Prc (1 may be at or above lateral midline at base of caudal peduncle). Dn present; either 2 horizontal Pol near lateral line or VO1-3 on a straight ascending line with VO4-5 level. VO1-3 on a straight, inclined, ascending line with VO4-5 level. One caudal gland present. Supracaudal (males) and infracaudal (females) well developed; 1 pair (Dn) of luminous organs on head; luminous scale at PLO absent (FAO 2002).
Lobianchia gemellarii
Unique Characteristics: Pol midway between lateral line and anal-fin base or lower; SAO series on a straight or slightly curved line, with concavity directed posteroventrally; Prc evenly spaced, sometimes Prc4 somewhat displaced posteriorly; distance between Prc4 and Prc3 always shorter than distance between Prc1 and Prc3 (FAO 2020).
Similar Species:
Lobianchia dofleini, Meditteranean Divinglamp
Meditteranean Divinglamp, Lobianchia dofleini. Pol much closer to lateral line than anal-fin base or ventral contour of caudal peduncle; SAO forming gentle arc, with concavity directed anterodorsally; Prc4 separated from Prc3 by enlarged interspace, lying at base of middle caudal-fin rays; distance between Prc4 and Prc3 equal to or usually greater than distance between Prc1 and Prc3 (FAO 2020).
