ABSTRACTMesocoelium malayanum sp.n. is described from the frog Rana macrodon, in Malaysia. Elongate body, broader anteriorly, measuring 1·900 (1·679–2·070) mm long by 0·404 (0·380–0·437) wide, tegument aspinose oral sucker 0·212 (0·200–0·228) by 0·202 (0·191–0·205), acetabulum 0·141 (0·132–0·150) by 0·139 (0·123–0·146), prepharynx present, oesophagus 0·115 (0·096–0·137), caeca reaching posterior ⅓ of body, anterior testis 0·097 (0·087–0·110) by 0·091 (0·087–0·100) dorsal to acetabulum, posterior testis 0·094 (0·087–0·101) by 0·092 (0·091–0·100), cirrus pouch 0·121 (0·111–0·130) by 0·047 (0·041–0·055), genital pore at left of midline of oesophagus just anterior to intestinal bifurcation, ovary 0·110 (0·091–0·127) by 0·089 (0·085–0·096) on left of body and posterior to acetabulum, vitelline glands with single follicles extending from intestinal bifurcation to ends of caeca, excretory vesicle I-shaped and eggs 0·040 (0·037–0·046) by 0·023 (0·022–0·024). Although morphologically related to M. maroccanum and M. meggitti, M. malayanum is considered to be a new species.

AbstractDolichorchis lacombeensis sp. nov., a digenean parasite of the gut of the cocoi heron, Ardea cocoi (L.), is described as a new species from Buenos Aires Province, Argentina. This new species most closely resembles D. buteii and D. tregenna in the distribution of the vitelline follicles, which reach the intestinal bifurcation in the forebody. D. buteii can be distinguished from D. lacombeensis sp. nov. by the distribution of the vitelline follicles in the hindbody, which are concentrated in midline, by the presence of a sphincter in genital pore and by the size of holdfast organ and posterior testis, which are larger, (240–400 × 176–240 and 315–464 × 240–410 µm, respectively). D. tregenna differ from the new species by their larger measurements (pseudosuckers’ length 90–100, pharynx 52–90 × 50–70 and eggs 89–104 × 48–68 µm).

Description. Body more or less elongated, narrowing anteriorly and posteriorly. Length 1·34–1·441, maximum width 0·476, maximum thickness 0·433, both measured in the region of adhesive apparatus. Entire surface of the body, except adhesive apparatus and the region posterior to second testis, covered with fine spines. Ventral folds originate approximately at centre of body and meet a little behind the level of posterior third to form a shallow cavity occupied by the adhesive apparatus. Adhesive apparatus smooth, oval, 0·4–0–44 long, 0·26–0–3 wide, with narrow central depression, anteriorly reaching acetabulum and posteriorly anterior margin of posterior testis. In it are imbedded vitelline follicles, anterior testis, ovary and anterior portions of cirrus sac and uterus.

The present investigation deals with the systematic observation of a new species of Phyllodistomum khadensis Sp. Nov. from fresh water fish Wallago attu. The worm is close to all species of genus phyllodistomum in general the body is narrow while the posterior portion of the body is broad and triangular in shape. The oral sucker is terminal. The ventral sucker is rounded in structure and larger than oral sucker. The bladder is long and tubular.The anterior testis is smaller than posterior one. Vas deferans is long, tubular and forms vasa efferentia. Female reproductive organ includes single ovary having its duct. The vitelline glands are two in number compact lobes on either side of the ootype. The eggs are oval to round in shape.

Szidatitrema yamagutii n. sp. was found in the air sacs and body cavities of 2 bearded barbets, Lybius dubius, and a white-necked myna, Streptocitta albicollis, that died at the Audubon Zoo, New Orleans, Louisiana between June, 2000 and April, 2005. The new species can be distinguished from Szidatitrema philomachii and Szidatitrema vogeli, the only species currently assigned to this genus, by having a smaller egg size (80–105 by 40–55 compared to 117–126 by 54–72 and 110 by 50, respectively) and the testes of S. yamagutii n. sp. are less obliquely positioned relative to each other. Szidatitrema yamagutii n. sp. further differs from S. philomachii by lacking an oral sucker and having larger testes (anterior testis 405 by 375 compared to 270 by 210; posterior testis 435 by 370 compared to 225 by 210) and from S. vogeli by having a shorter cirrus sac (345 compared to 554) ), smaller testes (anterior testis 405 long compared to 700; posterior testis 435 long compared to 500), a smaller ovary (220–330 wide compared to 400), and a larger postovarian space (approximately 10% of body length compared to 6%). This new species was likely introduced into the Audubon Zoo through the importation of species of Old World birds.

AbstractA new species of Acanthocolpidae, Stephanostomum adlardi is described from the serranid Plectropomus leopardus from Lizard Island in the northern Great Barrier Reef. It differs from all previously described acanthocolpids in the structure of the oral sucker which is extended into dorsal and ventral lobes each bearing a row of spines. A phylogenetic tree estimated from combined nuclear small and partial large ribosomal RNA gene sequences shows that, despite the unusual oral sucker structure, the species is a true member of the genus Stephanostomum. The molecular results also suggest that Monostephanostomum nolani is derived from within Stephanostomum.

AbstractA new species of Skrjabinolecithum (Digenea: Waretrematinae), Skrjabinolecithum pyriforme n. sp., has been found in the intestines of Liza haematocheila and Mugil cephalus from the Primorsky Region, Russia. These worms differ from S. vitellosum and S. lobolecithum by the presence of two caeca, as do S. spasskii, S. indicum and S. bengalensis. These species differ morphologically from S. pyriforme n. sp. by a number of features, including body width, oral sucker, pharynx, eggs and ratio of length and width of the body. The most similar species to S. pyriforme n. sp. is Platydidymus flecterotestis (Zhukov, 1971) with some differences in maximal body length, testis and egg sizes. The results of molecular analysis confirmed that this new species belongs to Skrjabinolecithum on the basis of close relationships with S. spasskii-type species.

A new species is of the genus Sanguinicola Plehn, 1905 described, Sanguinicola platyrhynchi n. sp., digenetic parasite of visceral cavity of Hemisorubim platyrhynchos (Valenciennes, 1840) from the floodplain of the upper Paraná River, Brazil. The species has been thus included because of the presence of separate dorsal genital pores, while differing from other species of the same genus mainly in digestive apparatus features, genital pore position, and infection site. Emendation of generic diagnosis is included.

Odhner's specimens of Gymnophallus somateriae were studied and are assigned to a new genus and new species because of the wide genital pore located between the ventral sucker and the intestinal bifurcation. Paragymnophallus odhneri also differs from G. somateriae as described by Levinsen (1881) and Ching (1973), in the body spination, 2:1 sucker ratio, nature of the vitellaria, and the egg size. G. somateriae reported by Ryzhikov et al. (1966) from Somateria spectabilis in Chutkova is considered to be P. odhneri because of the checkerboard arrangement of spines, 2:1 sucker ratio, and small eggs. Pending reexamination of the genital pore, G. bilis Brinkmann, 1956 and G. minor Ryzhikov, 1962 could belong to Paragymnophallus. The new genus, most similar to Gymnophallus in the bipartite seminal vesicle, follicular vitelline glands, and Y-shaped excretory bladder, differs in the location and size of the genital pore, larger sucker ratio, and large pharynx. The wide genital pore some distance from the ventral sucker and the large oral sucker are like that of Parvatrema but Parvatrema has a club-shaped seminal vesicle, minute body, compact vitellaria, and V-shaped excretory bladder. A key to the genera of Gymnophallidae is included.

AbstractChoanocotyle platti sp. nov. (Digenea, Choanocotylidae) is described from the northern long-necked turtle, Chelodina rugosa (Pleurodira, Chelidae) from the Daly and Mary Rivers, Northern Territory, Australia. This is the fifth known member of Choanocotyle. Choanocotyle platti sp. nov. differs from Choanocotyle nematoides Jue Sue et Platt, 1998 and Choanocotyle hobbsi Platt et Tkach, 2003 by smaller body length, larger oral sucker, relatively greater distance between tests, and prepharynx with an infolded posterior region. In addition the new species does not have the looped cirrus sac characteristic of Choanocotyle nematoides. Comparison of sequences of 18S, ITS (ITS1, 5.8S, ITS2) and partial 28S regions of nuclear rDNA among all 3 species strongly supports the status of Choanocotyle platti sp. nov. as a new species.
