Hemilamprops californicus Zimmer, 1936

Hemilamprops ? californica Zimmer, 1936: 429–431 , fig. 36a–d.

Hemilamprops californica .— Gamô, 1962: 199, fig. 34.

Hemilamprops californiensis .— Lie, 1969: 21–22.

Type material. Holotype; USNM 71439 , ovigerous female . Paratypes: USNM 71471 , 2 ovigerous females. Off Corona del Mar, California.

Diagnosis. Carapace with 1 pair lateral ridges, without setae, dorsal crest entire. Telson 1.0 length of uropod peduncles, with 3–5 pairs lateral setae, 5 terminal setae, outermost pair longest, inner pair shortest. Uropod exopod article 1 1.2 length of article 2. Adult male shorter than female, antenna extending to posterior border of pleonite 5; telson with 5 pairs lateral setae; uropods more setose than in female.

Depth. 20–30 m.

Distribution. Eastern Pacific, Vancouver to California.

Remarks. Given the remarks of Harada (1959) about the substantial differences between his specimens and those of Zimmer, it is likely that the specimens Harada described from Japan are not the same species as H. californicus Zimmer, 1936 , thus Japan is not included in the distribution. The most similar species is H. pacificus , which can be distinguished by the different proportions of the uropod exopod. In H. californicus article 1 of the uropod exopod is subequal to article 2, while in H. pacificus article 1 of the uropod exopod is distinctly shorter than article 2.
