| Descripción: | Genitocotyle acirrys, a parasite of fishes of the Embiotocidae family in California, U.S.A. is redescribed, taking into consideration that after Park's original description, it has only been quoted. Redescription is necessary since there are some structures that were not given precisely. The oral sucker is smaller than the acetabulum ; a muscular genital sucker is present; the pharynx adheres to the oral sucker ; testes are slightly slanted, one behind the other and large; the seminal vesicle which is diffuse, extends [rom the middle of the ventral sucker to the genital pore level; there is no cirrus pouch; genital pore anterior to the intestinal bifurcation and sinestral; there are only a few large eggs; vitelline glands arise a little behind the ventral sucker and are composed of small vitelline follicles; the vesicle is saculiform. We have identified it in fishes of the Sciaenidae family (Genyonemus lineatus), also from California, U.S.A.Dactylostomum winteri Caballero y C. et Caballero R., 1971 is a parasite of Paralabrax maculatojasciatu (Steindachner, 1868) in Baja California, Mexico. We have also identified it in Clinocottus analis australis Hubbs, 1926, from California, U.S.A. These specimens are a little different from the type species. They are smaller, and the vitelline glands reach to the posterior border of the acetabulum, further, the host and the locality are different. |
