Capsaloides sinuatus ( Goto, 1894) Price, 1938 View in CoL ( Fig. 1 View FIGURE 1 G)
Synonyms: Tristomum sinuatum Goto, 1894 ; Capsala sinuata ( Goto, 1894) Johnston, 1929 ; Capsaloides sinuatum ( Goto, 1894) Price, 1938 .
Typehost: Histiophorus sp. ( Istiophoridae ). Goto (1894) lists the Japanese name “kajiki” as the host of C. sinuatus . Lawler (1981) noted that with this Japanese name, the host is likely now known as Istiophorus platypterus .
Typelocality: Misaki, Japan [Pacific Ocean].
Site: Inner side of gills.
Additional record: Gills of Tetrapterus audax (Philippi, 1887) , Hawaii, USA [Pacific Ocean] (see Yamaguti 1968).
Specimens examined: Two voucher specimens (CNHE 002739).
Remarks
We were unable to locate typematerial to verify the original description or the 5 specimens upon which the redescription was based (see Yamaguti 1968). The haptoral accessory sclerite ( Fig. 1 View FIGURE 1 G; redrawn from Goto 1894) does not appear to be completely in profile in a flattened dorsoventral orientation. Goto (1894) described the uterus as opening into the “genital atrium” near the common genital pore but Yamaguti (1968) depicted the uterus as having a separate aperture. Goto (1894) based his description on careful observations of whole and sectioned material. Furthermore, in all other species of Capsaloides , the uterus joins the male copulatory organ canal just before the common genital pore. Therefore, it is likely that Yamaguti’s depiction of a separate uterine aperture is incorrect.
We examined 2 voucher specimens identified by LamotheArgumedo as C. sinuatus . These worms were collected from the gills of T. audax caught off Mazatlan, Mexico. We cannot distinguish these apparent C. sinuatus specimens from the holotype of C. cristatus . The dorsomarginal body sclerites of the 2 voucher specimens are identical to C. cristatus . Of particular note is the presence of the left anterior isolated group of dorsomarginal body sclerites (6–7 isolated sclerites with 6–10 cusps) in the 2 voucher specimens which was not described for C. sinuatus by Goto (1894). If these voucher specimens are indeed C. sinuatus , this provides further support for the synonymy of C. cristatus with C. sinuatus . However, until typematerial is located or additional specimens from the typelocality are collected, we choose not to make this decision.
