Image copyrights: Dennis Allen

Size: 11 mm TL (male); 11.5 mm TL (female)

Color: Almost transparent in life

Body is small, thin, integument smooth and transparent. Eyes are large, prominent, on stout conical stalks. Rostrum is small, a spine on each side behind eye and at anterolateral corner. First antennular segment in male reaches just beyond the front margin of cornea, in female it reaches very considerably beyond the cornea. Last segment of antennal peduncle in male reaches middle of cornea and distal third of first segment of antennular peduncle. In female last segment of antennal peduncle reaches proximal margin of cornea. Petasma-terminal portion tapers gradually from base with acute end considerably curved, but a short part near the end is curved in the opposite direction. A small median spine above base of telson. Telson slender, about half-length of uropods; truncate distally with a strong spine at each corner; two pairs of intermediate spines on distal border and two pairs of lateral spines about equidistant. Exopod of uropod-terminal margin is oblique; marginal apical process reaches beyond the upper distal angle in male; does not reach the upper angle but the terminal margin is always oblique in female.

Similar species: The two ventral processes on the sixth abdominal segment in male are shaped similarly like those of Lucifer intermedius but the anterior process is placed more backwards in Lucifer faxoni. Males of L. faxoni and L. hanseni show resemblance in the terminal portion of the petasma.
