In the most recent revision of the family Haploporidae Nicoll, 1914, <jats:italic>Parasaccocoelium<\/jats:italic> Zhukov, 1971 was synonymized with <jats:italic>Pseudohapladena<\/jats:italic> Yamaguti, 1952 (Overstreet &amp; Curran, 2005). Here, we restore the genus <jats:italic>Parasaccocoelium<\/jats:italic>. The species described by Zhukov can be distinguished from the species <jats:italic>Pseudohapladena sensu<\/jats:italic> Yamaguti, 1952 using a combination of the following features: (1) diffuse or absent eye-spot pigment; (2) subterminal or terminal oral sucker; (3) present or absent genital atrium; and (4) vitellarium with two large and compact vitelline masses, or vitelline follicles tubular and divided into two groups. For the species of <jats:italic>Pseudohapladena<\/jats:italic>, i.e. <jats:italic>P<\/jats:italic>. <jats:italic>scatophagi<\/jats:italic>, Yamaguti noted that the vitelline follicles occupy almost the entire post-testicular region, but in the present specimens, the vitelline follicles do not occupy the post-testicular region. Based on the diagnosis of <jats:italic>Pseudohapladena<\/jats:italic> by Overstreet &amp; Curran (2005), the genus <jats:italic>Parasaccocoelium<\/jats:italic> differs in the following features: (1) a single testis that is longitudinal, longitudinally oval, spherical, transversally oval, irregular, bilobed or V-shaped, or a testis that is subspherical to irregular to elongate; (2) the vitellarium in the lateral fields formed from large compact follicles that have an irregular form and extend between the anterior margin of the ventral sucker or pharynx and posterior margin of the testis, and the vitelline follicles do not occupy post-testicular regions; or the vitellarium consists of elongate groups of follicles that usually extend at least one-half of a body length and extend to the posterior end of the body in some and to the posterior margin of the testis in others; (3) the eggs are operculate, unembryonated and developed when laid, or the eggs in some cases are only operculate; and (4) a developed miracidium with or without an eye spot. New data have been added to the description of <jats:italic>Parasaccocoelium mugili<\/jats:italic> Zhukov, 1971 based on new material, and two new species of this genus, <jats:italic>Pa. haematocheilum<\/jats:italic> n. sp. from <jats:italic>Liza haematocheila<\/jats:italic> and <jats:italic>Pa. polyovum<\/jats:italic> n. sp. from <jats:italic>L. haematocheila<\/jats:italic> and <jats:italic>Mugil cephalus<\/jats:italic>, are described using morphological and molecular approaches. We support the taxonomic status of the genus <jats:italic>Parasaccocoelium<\/jats:italic> and its inclusion within the sub-family Waretrematinae, and we consider <jats:italic>Pseudohapladena lizae<\/jats:italic> Liu et Yang, 2002 to be a junior synonym of <jats:italic>Parasaccocoelium mugili<\/jats:italic> Zhukov, 1971.<\/jats:p>","DOI":"10.1017\/s0022149x14000443","type":"journal-article","created":{"date-parts":[[2014,6,11]],"date-time":"2014-06-11T07:25:21Z","timestamp":1402471521000},"page":"565-576","source":"Crossref","is-referenced-by-count":16,"title":["Restoration of the genus <i>Parasaccocoelium<\/i> Zhukov, 1971 (Digenea: Haploporidae) and a description of two new species from mugilid fish in the Far East of Russia"],"prefix":"10.1017","volume":"89","author":[{"given":"V.V.","family":"Besprozvannykh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.M.","family":"Atopkin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.V.","family":"Ermolenko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.Yu.","family":"Nikitenko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,6,10]]},"reference":[{"key":"S0022149X14000443_ref10","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7519(03)00049-3"},{"key":"S0022149X14000443_ref8","first-page":"237","article-title":"Digenetic trematodes from marine fishes of Waltair coast, Bay of Bengal, Families Haplosplanchnidae and Haploporidae","volume":"40","author":"Madhavi","year":"1979","journal-title":"Rivista di Parassitologia"},{"key":"S0022149X14000443_ref7","doi-asserted-by":"publisher","DOI":"10.1645\/0022-3395(2002)088[0358:TNSOPY]2.0.CO;2"},{"key":"S0022149X14000443_ref1","first-page":"277","article-title":"Contribution to the systematic of trematode family Haploporidae Nicoll, 1914","volume":"7","author":"Belous","year":"1954","journal-title":"Proceedings of Laboratory of Helminthology"},{"key":"S0022149X14000443_ref6","doi-asserted-by":"publisher","DOI":"10.1126\/science.1065889"},{"key":"S0022149X14000443_ref9","doi-asserted-by":"publisher","DOI":"10.2307\/3225173"},{"key":"S0022149X14000443_ref16","first-page":"633","volume-title":"Principles and procedures of statistics","author":"Steel","year":"1980"},{"key":"S0022149X14000443_ref17","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msr121"},{"key":"S0022149X14000443_ref3","doi-asserted-by":"publisher","DOI":"10.2478\/s11686-006-0037-1"},{"key":"S0022149X14000443_ref18","first-page":"186","volume-title":"Interrelationships of platyhelminthes","author":"Tkach","year":"2001"},{"key":"S0022149X14000443_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.parint.2009.03.006"},{"key":"S0022149X14000443_ref11","doi-asserted-by":"publisher","DOI":"10.1079\/9780851995878.0129"},{"key":"S0022149X14000443_ref12","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/14.9.817"},{"key":"S0022149X14000443_ref13","doi-asserted-by":"publisher","DOI":"10.1007\/s11230-012-9401-8"},{"key":"S0022149X14000443_ref14","doi-asserted-by":"publisher","DOI":"10.1645\/12-106.1"},{"key":"S0022149X14000443_ref19","doi-asserted-by":"publisher","DOI":"10.1023\/A:1025546001611"},{"key":"S0022149X14000443_ref5","first-page":"1","volume-title":"Mr Bayes: Bayesian inference of phylogeny","author":"Huelsenbeck","year":"2000"},{"key":"S0022149X14000443_ref20","first-page":"33","volume-title":"The DNA book: Protocols and procedures for the modern molecular biology","author":"Truett","year":"2006"},{"key":"S0022149X14000443_ref21","first-page":"146","article-title":"Parasitic worms mainly from Celebes.
