Type locality and specimens. Ellis Boat Landing , California. Holotype, male, 8.0 mm, AHF5110 ; paratype, female, 6.0 mm.

Material examined. No material available for examination. Diagnosis based on description by Barnard (1959).

Diagnosis. Minute accessory flagellum. Gnathopod 1 propodus curved; dactylus very short. Gnathopod 2 carpus distally truncate and spoon-like. Leucothoe alata Barnard, 1962 shows gnathopod 1 propodus as less inflated than in the original description and gnathopod 2 carpus without the spoon-like apex. Leucothoe alata Hirayama, 1985 displays a thick article 2 of the mandibular palp; a heavily setose maxilla 2; and a straight gnathopod 1 propodus; suggesting that this may be a distinct species.

Note. Examination of the type material is necessary to determine if these reports are all Leucothoe alata Barnard, 1959

Female (sexually dimorphic characters). Gnathopod 1 propodus curved. Gnathopod 2 carpus distally tapered.

Habitat. Floating docks; depth not reported, littoral.

Host. Sponges.

Distribution. Pacific Ocean: Monterey Bay to San Ramon Bay, California (J.L. Barnard 1952; J.L. Barnard 1955; J.L. Barnard 19562a; J.L. Barnard 1964a; J.L. Barnard 1964b; J.L. Barnard 1966; J.L. Barnard 1969a; J.L. Barnard 1969b; J.L. Barnard 1979); West Kyushu, Tomioka Bay, Japan ( Hirayama 1985c).
