FIGURE 1 in Rediagnosis of Ichthyotrema Caballero & Bravo-Hollis, 1952 (Digenea: Gyliauchenidae Fukui, 1929), including the redescription of I. vogelsangi Caballero & Bravo-Hollis, 1952

FIGURE 1. Ichthyotrema vogelsangi Caballero & Bravo-Hollis, 1952 from the intestine of Prionurus punctatus. Paratype (UNAM 001051.09). A. View of entire worm. Note that the path of the caeca is obscured by the extensive vitellarium and that the specimen is distorted; the anterior of the body is presented dorsoventrally, whereas the posterior extremity is mounted laterally. Scale bar = 500 µm. Legend: gp, genital pore; ob, oesophageal bulb; oes, oesophagus; ph, pharynx; t, testes. B. Detail of cirrus-sac. Note that the muscular capsule surrounding the globular proximal portion of the cirrus-sac, which contains the ejaculatory duct, is contiguous with the capsule surrounding the pars prostatica and the proximal portion of the seminal vesicle. In addition, the prostate glands are external to the cirrus-sac wall, and the tails of these glands penetrate the wall laterally. Scale bar = 250 µm. Legend: pg, prostate glands; pp, pars prostatica; sv, seminal vesicle.
