148 JOURNAL OF THE HELMINTHOLOGICAL SOCIETY OF WASHINGTON, 66(2), JULY 1999 Figure 1. Pseudacanthostomum panamense. A-D, holotype from Galeichthys (=Arius) seemani, Panama (IBUNAM 947), ventral view. A: oral sucker; B: ventral sucker and terminal genitalia; C: anterior part of body; note extent of vitelline follicles; D: posterior extremity; note connection of intestinal ceca with excretory bladder and presence of uroproct; E-H, acetabular region; note variation in anterior extent of vitelline follicles (E, F: specimens from Ariopsis assimilis, Mexico; G, H: specimens from A. seemani, Columbia; E: dorsal view, ventral follicles omitted; F, G: ventral view, dorsal follicles dashed; H: ventral view but dorsal follicles drawn in full and ventral follicles dashed). Scale bars in millimeters. Abbreviations: e, eggs; exb, excretory bladder; gp, genital pore; ic, intestinal ceca; sr, seminal receptacle; sv, seminal vesicle; u, uterus; up, uroproct; vf, vitelline follicles; vs, ventral sucker. duct; genital pore close to anterior margin of ventral sucker (Fig. IB). Ovary transversely elongate, slightly lobate (Fig. 1C) or with almost indistinct lobes (Fig. 2A), pretesticular. Seminal receptacle oval, preovarial or anterolateral to ovary (Fig. 1C). Vitelline follicles numerous, dorsally filling space between ventral sucker and ovary, ventrally forming 2 lateral bands starting at acetabular level or posterior to ventral sucker and reaching posteriorly to anterior margin of anterior testis (Figs. 1E-G, 2G); exceptionally, vitelline follicles preacetabular. Uterus sinuous, with numerous loops, reaching to body extremity posteriorly and completely filling body posterior to ovary (Fig. 2A, G, F). Metraterm thin-walled, opening into hermaphroditic duct. Eggs operculate, rather variable in size (Figs. 3, 4). Excretory bladder Y-shaped, long, with anterior branches anterolateral to intestinal ceca, reaching to pharynx (Figs. 1C, 2A, C, F).

Adults from Ariopsis seemani, Colombia (A—D, G); nietacercariae from Dormltator latifrons, Mexico (E, H, I); adults from A. assimilis, Mexico (F, J, K). A, E, F: total view. B, H-K: oral sucker with circumoral spines. B: tegumental spines on only the right side and subtegumental gland cells on the left side are illustrated. C: detail of acetabular region with terminal genitalia; note connection of dorsal vitelline follicles (dashed) at level of ovary. D: posterior extremity with connection of intestinal ceca, opening to the outside, with the excretory bladder (uroproct). G: posterior part of body; note vitelline follicles reaching posteriorly to level of anterior testis. Scale bars in millimeters. Copyright © 2011, The Helminthological Society of Washington
