Description
Haplonema hamulatum Moulton, 1932
Description (after Arthur & Margolis 1975). With characteristics of the genus. [Two sets of measurement are given, the first for syntypes, the second in parentheses for material collected subsequently.]
Males: syntypes length not available (8.31–11.76); maximum width 0.20 (0.14–0.20). Cuticular striations very fine. Head with four submedian double papillae, two lateral amphids, and six radially arranged ridges, one extending from each of the papillae and amphids to rim of mouth. Lips and buccal capsule absent, mouth opening directly into oesophagus, 0.512 (0.595–0.890) long. Nerve ring 0.248 (0.312–0.383) from anterior end. Excretory pore slightly posterior to oesophago-intestinal junction, distance from anterior end not available for syntypes (0.717–1.036). Lateral alae extending 1.03 (0.828–1.840) posteriorly from anterior end. Digitate deirids anterior to oesophago-intestinal junction, 0.392 (0.450–0.754) from anterior end (Fig. 99 A). Testis originating a little anterior to anus and extending anteriorly beyond mid-body before doubling back to proceed posteriorly and join seminal vesicle. Spicules short, about equal: left one 0.130–0.151 (0.118–0.157), right one 0.130–0.150 (0.104–0.156) long. Gubernaculum wedge-shaped, 0.036–0.041 (0.027–0.045) long. Eleven pairs caudal papillae and one unpaired median pre-cloacal papilla. Phasmids not observed. Caudal alae present, extending from tip of tail to slightly anterior to 1st pair caudal papillae. Tail attenuated, 0.214–0.229 (0.156–0.230) long (Fig. 99 B).
Females: 9.50–9.91 (9.51–10.88) long; maximum width 0.22–0.28 (0.16–0.18). Head and oesophagus
structure and cuticular striations as in males. Oesophagus 0.602–0.615 (0.628–0.709) long. Nerve ring 0.325–0.461
(0.310–0.372) from anterior end. Lateral alae extending posteriorly 1.03–1.84 (1.43–1.69) from anterior end.
Deirids 0.511–0.523 (0.486–0.582) from anterior end. Excretory pore a little posterior to oesophago-intestinal
junction, 0.692–0.794 from anterior end. Vulva prominent, protruding beyond body wall and guarded by two
digitate lateral projections, 5.42–5.79 (5.97–6.67) from anterior end (Fig. 99 C). Muscular vagina directed
anteriorly, 0.177–0.186 (0.195–0.266) long. Uteri amphidelphic. Eggs 0.065–0.077 x 0.043–0.051 (0.050–0.072 x
0.047–0.058). Tail 0.457–0.486 (0.0470–0.538) long. Phasmids not observed.

Hosts: Lota lota (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14); Oncorhynchus mykiss (8, 11); Prosopium williamsoni (8, 11); Salvelinus malma (8, 11)
