Description (after Margolis 1977). With characterisitics of the genus.

Males: 26.3–36.9 long, 0.19–0.21 maximum width. Nerve ring 0.264–0.281 and excretory pore 0.401–0.446 from anterior end. Buccal cavity 0.077–0.115 long. Muscular oesophagus 0.894–1.030, and glandular oesophagus 6.41–8.83 long; ratio of their lengths 1: 7.2 to 1:1:8.6. Testis straight originating anterior to oesophago-intestinal junction, 7.14–9.75 from anterior end. Tail 0.275–0.326 long with rounded tip. Left spicule slender, 2.29–2.69 long; right spicule 0.168–0.184 long; ratio 13.6–15.4:1. Pre-cloacal papillae arranged in couples, two pairs immediately pre-cloacal, and two pairs slightly anterior to level of proximal end of withdrawn right spicule. First five pairs post-cloacal papillae approximately evenly distributed over length of tail. Phasmids at tail tip ( Fig. 57 View FIGURE 57 A).

Females: 46.3–74.2 long, 0.22–0.34 maximum width. Nerve ring 0.261–0.349 and excretory pore 0.374–0.588 from anterior end. Buccal cavity 0.092–0.117 long. Muscular oesophagus 0.870–1.166 and glandular oesophagus 7.33–11.61 long: ratio of their lengths 1:8.1 to 1:1:9.9 ( Fig. 57 View FIGURE 57 B). Anterior ovary originates near oesophagointestinal junction; posterior ovary originates near level of anus. Vulva 26.25–36.15 or 48.7%–56.7% of total body length from anterior end of body. Eggs with vermiform larvae when shed, 0.043–0.047 x 0.028–0.032: at one pole a large plug with two long and up to six shorter more delicate filaments; at opposite pole a small plug with up to four of the shorter filaments ( Fig. 57 View FIGURE 57 C). Tail 0.196–0.285 long. Phasmids near tail tip ( Fig. 57 View FIGURE 57 D). Sites: intestinal lumen, pyloric caeca

Hosts: Scorpaenichthys marmoratus (1, 2); Sebastes nebulosus (3)

Distribution: Pacific
