10. Oesophagus shorter than pharynx, vitellaria extending caecal ends; pharynx/body length ratio: 1:3. 8 C. pygmaeus - Oesophagus longer than pharynx, vitellaria post caecal; pharynx/body length 1:5.1 C. dolichocotyle 11. Vas deferens single, vitellaria postcaecal C. cohni - Vas deferens double, vitellaria extending at about middle part of caeca . . .77777777 C. freitaslenti Dermatemytrema Price, 1937 When describing this species, PRICE (1937) assigned it to the subfamily Diplodiscinae. Later, YAMAGUTI (1971) set up a new subfamily, Dermatemytrematinae for it on the basis of the presence of a so-called hermaphrodite pouch. It was pointed out above, that due to the misinterpretation of the structure of the genital opening, the designation of the subfamily is not justifiable. Thus, the genus is retained again to this subfamily. Diagnosis. Diplodiscinae. Body pyriform with indistinct ridge-like collar near anterior end. Primary pharyngeal sacs moderately developed. Pharynx Megalodiscus-type; oesophagus long, bulbus present; caeca short extending anterior margin of vitellaria. Genital opening anterior to bifurcation. Cirrus pouch present, testis single, lateral. Ovary median, vitellaria consisting of relatively few large follicules, forming preacetabular band across body. Eggs large, thinshelled, few. Acetabulum large, somewhat triangular, Catadiscus - type. Lymph system consisting of 2 pairs of longitudinal canals, one pair dorsal and others ventral to intestinal caeca. Laurer's canal present, opening anterior to excretory apeture. Parasitic in endgut of turtle. Type and single species: Dermatemytrema trifoliata Price, 1937 (Fig. 13). Progonimodiscus Ver cammen-G rand jean, 1960 In 1926 ORTLEPP described Diplodiscus doyeri from the South African forg, Xenopus laevis. It was re-named by VERCAMMEN-GRANDJEAN (1960) and placed to the genus Progonimo discus, set up by himself and two subspecies were designated. PRITCHARD (1964), examining VERCAMMEN-GRANDJEAN' s original material, found that the distinguishing of the two subspecies was unjustified and the species P. doyeri (ORTLEPP, 1926) VERCAMMEN-GRANDJEAN, 1960 was accepted. GROBBELAAR' s (1922) species (D. subclavatus from South Africa) has to be listed to this species. Diagnosis. Diplodiscinae. Body cylindrical. Primary pharyngeal sacs well developed. Pharynx Microrchis-type. Oesophagus short with well developed bulb, caeca short, divergent not reaching testis. Testis single, transversely elongated, almost equatorial, median. Two vasa efferentia uniting with each other ventral to intestinal bifurcation; vas deferens sigmoid. Cirrus pouch fusiform, genital opening behind oral sucker. Ovary ovoid, submedian. Vitellaria symmetrical, lateral, situated between caecal end and acetabulum. Transverse coils of uterus reaching lateral margin of body between acetabulum and genital opening. Eggs large, numerous, embryonated. Acetabulum ventroterminal, large, complex in structure with ruffled peduncle, Progonimodiscus-type. Excretory opening dorsal in front of acetabulum. Parasitic of amphibians. Type and single species: Progonimodiscus doyeri (Ortlepp, 1926) Vercammen-Grandjean, 1960 (Fig. 24) ~~ Pseudodiplodiscus Szidat, 1939 emended Manter, 1962 This genus was set up by SZIDAT (1939) for the species Diplodiscus cornu (Diesing, 1836) Daday, 1907 found in South American fresh water fish, Doras dorsalis. Generic diagnosis was formulated by MANTER (1962).
