Gyrodactylus gambusiae Rogers & Wellborn, 1965

( Figure 12 ; Tables 4 and 7)

Type host: Gambusia affinis Baird & Girard (“mosquitofish”, “guayacón mosquito”).

Site of infection: Fins and body.

Type locality: Welaka Lake, Putnam Co., Florida, USA.

Type material examined: One paratype ( USNPC 908–19/20).

Comments: Ventral bar not visible in paratype. The large open faced, angular marginal hook sickles of G. gambusiae are readily differentiated from those of both G. j a ro c h o sp. nov. and G. xalapensis sp. nov. ( Figures 13, 14 ). The marginal hook sickles of G. gambusiae are morphologically similar to those of Gyrodactylus milleri Harris & Cable, 2000 (all three marginal hook types - see the full description below) and G. turnbulli . The sickle point of G. gambusiae , which quickly narrows abruptly to give a short tip, however, most readily discriminates this species from the latter two, which have longer, more slender sickle points.
