Hippolyte trisetacea Heller, 1861:29.

Hippolysmata paucidens Rathbun, 1906:913, pl. 24: fig. 4.

Lysmata paucidens (Rathbun).—Schmitt, 1939:12.

Lysmata trisetacea (Heller).—Holthuis, 1947:19, 65—Chace, 1962:614.

MATERIAL.—6 males, 1 immature male, 5 non-ovigerous females, 9 ovigerous females, Malpelo coll. no. 3.

MEASUREMENTS.—Immature male cl 1.8 mm, males cl 2.9–3.8 mm, non-ovigerous females cl 2.9–6.0 mm, ovigerous females cl 4.0–5.1 mm.

DISTRIBUTION.—The species has previously been reported from the Red Sea, western Indian Ocean, the Malay Archipelago, Micronesia, New Zealand, Hawaiian Islands, Clipperton Island (Holthuis, 1958; Chace, 1962), and now Malpelo Island. Neither this species nor L. galapagensis appear to occur on the western American mainland. Lysmata californica (Stimpson, 1866) occurs in California and is common in the Gulf of Panama while L. porteri (Rathbun, 1907) occurs in Chile. The record of Sivertsen (1934) for L. intermedia (Kingsley, 1878), a western Atlantic species, is based on a single specimen from the Galapagos Islands, which appears to be within the range of variation of L. californica (see Sivertsen, 1934, pl. 2: figs. 9–15; and Limbaugh, Pederson, and Chace, 1961, fig. 7).
