| Summary: | ** Philonema agubernaculum Simon & Simon, 1936 Synonym: ** Philonema salvelini Richardson, 1936 Description (after Simon & Simon 1936). With characteristics of the genus. Males: mean 16.5 (range 12–23) long; mean maximum width 0.296. Mean lengths of the muscular and glandular portions of the oesophagus are 0.404 and 1.122 respectively. Anus to tail tip averages 0.276. Spicules equal, sharply curved, lightly chitinized, mean length 0.284 (Fig. 36 A). Females: 86.1 (49–140) long; mean maximum width 0.771. Mean lengths of muscular and glandular oesophagus 0.553 and 1.172 respectively (Fig. 36 B). Anus to tail tip averages 0.446 (Fig. 36 C). Anus sometimes atrophied in gravid worms. Vulva and vagina atrophied in gravid worms. Small ovary present at each end of body. Uterus of gravid worms filled with embryos and occupying nearly all of the body cavity. Uteri of young specimens contains eggs in various stages of development. Eggs measure 0.032 x 0.046. Embryos 0.343 long. Comments: ** P. agubernaculum requires both redescription and much improved illustrations. A nerve ring is not mentioned in the original description so in Figure 36 B one has been added in a position based on the anatomy of ** P. oncorhynchi (see Fig. 37 B,D).
