Until the present report, it was represented by 19 species and of these, only Eurycyde spinosa Hilton, 1916 and Eurycyde clitellaria Stock, 1955 have been previously recorded for the eastern Pacific. The first one was described from Laguna Beach, California, the second described from the Virgin Islands in the Caribbean Sea and later reported from Tenacatita Bay, Jalisco by Child (1979). This report is the third finding of a species of Eurycyde in the eastern Pacific. Table 1 shows important characteristic features of these Eurycyde species.</p><p>Based on the key proposed by Nakamura and Chullasorn (2000), this species is very close to Eurycyde hispida Kroyer, 1844, described from Greenland and whose type material has been lost; Eurycyde hispida has also occasionally been reported from the coasts of the north Atlantic. Eurycyde hispida has plumose spines on its legs and abdomen, lateral process with setae laterally, coxa I without a lateral tubercle, and a tall thin ocular tubercle. In contrast, the new species has simple spines on the abdomen and legs, lateral processes without tubercles or spines, coxa I with two dorsolateral spines, and the ocular tubercle short, narrowing towards the tip. Another closely related species is Eurycyde spinosa Hilton, 1916. These two species can be separated by the presence of a large posterior spine on each coxa I, and the ocular tubercle is conical with one large spine and several smaller spines in Eurycyde spinosa, while Eurycyde bamberi sp. n. does not have posterior spines on the first coxa, and the ocular tubercle is globose, distally pointed, without spines.</p><p>The following species are illustrated and described in full since their previous descriptions are quite outdated and in some cases, like Nymphopsis duodorsospinosa, very incomplete. This will help facilitate future identification of eastern Pacific pycnogonids as well as help to differentiate new species as they are collected and described from this region.</p></div>	https://treatment.plazi.org/id/9AE80091DCC2BE1AF07CEAEAE9A56F91	Public Domain	No known copyright restrictions apply.

Hedgpeth (1948) cited this species from South Carolina and Florida, Child and Hedgpeth (1971) listed this species from the Galapagos. Child (1979) recorded this species from western Mexico and both coasts of Panama.</p><p>Remarks.</p><p>Hilton (1942c) noted that Nymphopsis duodorsospinosa is close to Nymphopsis spinosissima (Hall, 1912); however, these can be differentiated by the number of dorsal tubercles (two and three respectively), differences in the chelifore and chelifore scape, spination on the abdomen, lateral processes, and legs, propodal heel and sole spines, and size and shape of the eye tubercle. According to Hedgpeth (1948), the oviger of Nymphopsis duodorsospinosa is formed by ten segments, not nine as described by Hilton (1942c). Furthermore, the fifth segment in Nymphopsis duodorsospinosa is larger with a basal group of spines, not short and covered on all sides with small “hairs” as in Nymphopsis spinosissima .</p></div>	https://treatment.plazi.org/id/688BAB115C78E39B52A7F02717A14F2B	Public Domain	No known copyright restrictions apply.

Our specimen agrees with the original description of Callipallene californiensis, and is located within its range of distribution (California to Panama).

Propodus two times longer than tarsus, slightly curved, with a row of 19-20 sole spines, a median lateral row of ten spines, and two dorsal rows of 18-20 spines each, one row composed of short and the other of long spines. Main claw short, less than ¼ the length of the propodus, auxiliary claws nearly as long as main claw (Fig. 4G).</p><p>Oviger (Fig. 4D, E) inserted in the distal half of the first lateral process. First three segments short, first segment is half the size of the second one, second and third segments are subequal. Fourth and fifth segments longest, subequal. Fourth segment with two short ventral setae, and one long ventrodistal spine, fifth segment with a ventral row of three setae and one long ventrodistal spine. Sixth segment as long as the first and second together, with a ventral row of three setae. Last four segments armed with compound ovigerous leg spines, each with the following formula: 13: 9: 8: 10. Compound spines with 3-6 pairs of lateral teeth depending upon the size of the spine. Terminal claw long, curved, with six teeth (Fig. 4E).</p><p>Female gonopores oval in shape, present on ventrodistal end of coxa II of all leg pairs. These were observed on only two specimens (AD-8 and AC-15). All other specimens (males) without readily visible gonopores.</p><p>Abdomen as long as lateral processes of 4th pair of legs, elevated from the body at an angle of about 30° (Fig. 4A).</p><p>Standard measurements.</p><p>Proboscis 0.57 mm long, 0.28 mm wide.</p><p>Body 1.43 mm long from anterior end of cephalic segment to end of 4th lateral processes, 1.0 mm wide between second pair of lateral processes.</p><p>Leg 1 9.35 mm long from coxa I to the tip of main claw. Coxa I, 0.37 mm, coxa II, 0.71 mm, coxa III, 0.41 mm, femur 1.84 mm, tibia I, 2.02 mm, tibia II, 2.78 mm, tarsus, 0.35 mm, propodus 0.71 mm, claw 0.16 mm.</p><p>Oviger 3.19 mm long, first segment 0.78 mm, second 0.81 mm, third 0.38 mm, fourth 0.44 mm, fifth 0.19 mm, sixth 0.22 mm, seventh 0.38 mm, eighth 0.24 mm, ninth 0.24 mm, tenth 0.21 mm.</p><p>Distribution.</p><p>This species is known from Gulf of California and Panama: specimens from Gulf of California were taken on floating Sargassum around Puerto Peñasco, Sonora, and in Panama City, among hydroids and bryozoans (Child 1979, p. 40). With this record, the distribution of Nymphon lituus is extended to the western coast of Baja California Peninsula.</p><p>Remarks.</p><p>The genus Nymphon includes 277 valid species (Bamber et al. 2015). Despite the great diversity of the genus, only ten species are known from the eastern Pacific: Nymphon aculeatum Child, 1994 from San Clemente Basin, California; Nymphon apheles Child, 1979 from Panama; Nymphon duospinum (Hilton, 1942) from Alaska; Nymphon heterodenticulatum Hedgpeth, 1941 from Santa Catalina Island, southern California; Nymphon hirsutum Child, 1995 from the Bering Sea; Nymphon lituus Child, 1979 from the Gulf of California and Panama; Nymphon longicollum Hoek, 1881 from Chile (also from New Zealand and Auckland Islands); Nymphon pixellae Scott, 1912 from Vancouver, Canada (also from California and Japan); Nymphon similis Child, 1992 from Ecuador; and Nymphon stipulum Child, 1990 from southern California. Nymphon lituus is a species known only from its original description; the specimens found in this study vary slightly in the number of compound ovigerous leg spines, with the formula 13: 9: 8: 10, in contrast to the original description of Nymphon lituus with the formula 15: 10: 10: 11. The other features do not present major variations.</p></div>	https://treatment.plazi.org/id/2FE861EEED610F4D82F6389120E3FD31	Public Domain	No known copyright restrictions apply.

Femur is the longest segment, with two conical projections on dorsodistal end and a group of isolated setae on ventral surface. Tibia I is slightly shorter than femur and is nearly twice the length of tibia II, with two dorsodorsal conical projections, similar to those found on the femur, with a strong recurved spine between the conical projections, and isolated setae on the ventral surface; tibia II short, with a slight dorsal depression mid-segment, a strong distal recurved spine, and a small group of ventral setae placed in 3-4 regular rows.
