Sphenotic and preopercular spines well developed; symphysial spine of lower jaw short; frontals with a rounded dorsally directed projection; jaws badly damaged, upper jaw with about 12 or 13 teeth on each side, arranged in three overlapping series, the longest tooth 12.2% SL; lower jaw with about 11 or 12 teeth on each side, arranged in three overlapping series, the longest tooth 21.9% SL; two close-set teeth on vomer; second pharyngobranchials with 3 or 4 teeth, and third pharyngobranchials with 4 or 5 teeth; dorsal-fin rays 3; anal-fin rays 3; pectoral-fin rays 16, 16. Skin of head and body, stem of illicium, and proximal half of escal bulb, dark brown, fins pale; caudal peduncle with large subdermal melanophores arranged in an irregular ventrolateral series; a similar mid-lateral series just above midline of body; some melanophores present near base of dorsal-most caudal rays.
Metamorphosed females of Linophryne andersoni differ from those of all other species of the genus in details of escal and barbel morphology: escal bulb globular, with a low, rounded, distal prolongation, without appendages; two pairs of posterolateral appendages, inner pair short, outer pair less one-half diameter of escal bulb, each bearing a distal cluster of short filaments; a short simple lateral escal appendage on each side. Barbel divided near base into a median and two lateral primary branches, each with numerous secondary branches, each in turn with varying numbers of filamentous tertiary branches, the terminus of all branches bearing a single distal photophore; forming a symmetrical pair with secondary branches of decreasing length, spaced more or less equally along their length; median primary branch somewhat longer, divided into four secondary branches, two short and two long; longest secondary branch about 49% SL. Caudal peduncle with a ventrolateral series of large subdermal melanophores.
Known from a single specimen collected in the Central Tropical Pacific Ocean, northeast of the Line Islands, with gear fished open between the surface and 50 m.

Parasitized females have a single attached male, in contrast to the linophrynid genera Haplophryne and Borophryne (and the ceratiid genera Ceratias and Cryptopsaras) in which females with two or more males are known. In all known cases parasitized females of the family, the male is directed forward with respect to the female and attached in nearly the same position on the ventral midline of the female, somewhat in front of and below the sinistral anus; with only one or two exceptions, all are attached upside down with respect to the female. This is again in contrast to the linophrynid genera Haplophryne and Photocorynus (and the ceratiid genus Cryptopsaras) in which males may attach in any direction and almost anywhere on the head and body of the female. In all known examples, the males are attached by both upper and lower jaws, leaving prominent openings on each side that lead into their mouths and opercular cavities; there is no papilla of tissue projecting from the female into the mouth of the male.
Known from a single metamorphosed female at 32 mm SL.
