New Annotated Records of Helminth Parasites with Light Microscopy III Acanthocephala (Archiacanthocephala and Eoacanthocephala)

Abstract

We give an account of 8 species of acanthocephalans in two classes and 4 families collected from hosts in different geographical locations in Iran, India, Canada, Russia, and the USA. Each species account is annotated and morphologically presented using light microscopy showing characteristic diagnostic features. None of these accounts has been previously published. All geographical records and many host associations are new. In the Class Archiacanthocephala, we include Moniliformis kalahariensis Meyer, 1931 cystacanths (Moniliformidae) from Blattella (Phyllodromia) germanica Linn. in Bombay, India. In the Class Eoacanthocephala, we include Neoechinorhynchus (Hebesoma) carinatus Buckner and Buckner, 1993 from Erimyzon tenuis (Agassiz) in Louisiana, Neoechinorhynchus (Hebesoma) pungitius Dechtiar, 1971 in Lake Huron, Neoechinorhynchus (Neoechinorhynchus) rutili (Müller, 1780) Hamann in Stiles and Hassall, 1905 from Leuciscus idus (Linn.) in Lake Baikal, Russia Neoechinorhynchus (Neoechinorhynchus) tumidus Van Cleave and Bangham, 1949 from Coregonus sp. in Baunt Lake, Russia, and Tanaorhampus longirostris Van Cleave, 1913 cystacanth (Neoechinorhynchidae) in Ohio. In the eoacanthocephalan family Quadrigyridae, we also describe specimens of Acanthocephalorhynchoides cholodkowskyi (Kostylew, 1928), from Capoeta damascina (Valenciennes) in Iran and provide morphometric comparisons with other collections from elsewhere.
