Anamixis pacifica Thomas, 1997: 66 , fig. 10.

Type locality and specimens. Ellis Boat Landing , Newport Harbor, California, USA. Holotype, anamorph male, 5.0 mm, AHF531 .

Material examined. No material available for examination. Diagnosis based on description by Barnard (1955) and Thomas (1997).

Diagnosis. Gnathopod 1 propodus with a single terminal spine. The anamorph of this species was originally described as Anamixis linsleyi . Thomas [1997] noted that Anamixis pacifica , initially described as Leucothoides is assumed to be the leucomorph stage of A. linsleyi and takes page priority.

Leucomorph (juvenile/sexually dimorphic characters). Not confirmed. Male or female. Head anterior and anterodistal margins rounded. Antenna 1 flagellum nine articulate, accessory flagellum minute. Antenna 2 subequal to antenna 1; flagellum three articulate. Mandibular palp one articulate. Gnathopod 1 basis anterior margin bare, posterior margin with one seta; propodus smooth with five distal setae; dactylus very short. Gnathopod 2 coxa enlarged; basis anterior and posterior margins bare; propodus sub-triangular, palm serrate. Uropod 1 rami with robust setae.

Habitat. Floating docks; 1–15 m.

Host. Sponges.

Distribution. Eastern Pacific Ocean: Newport Bay, Carmel, California (J.L. Barnard 1955; J.L. Barnard 1964a; J.L. Barnard 1969a; J.L. Barnard 1979; Thomas 1997).
