The chromosomes of Szidatia joyeuxi were studied using cells of sporocysts from naturally infected molluscs Melanopsis dufouri (Castellon province, Spain). The diploid sets contain 18 chromosomes. The length of the first chromosome pair is equal to 16.9 µm and comprises up to 31.61% of the total haploid set length. In accordance with the centromere position, the S. joyeuxi karyotype structure is: 1m+ 2,3st+4a-st+5-9sm. There is a remarkable similarity between karyotypes of S. joyeuxi and other species of Cyathocotylidae (Cyathocotyle bithyniae, Paracoenogonimus ovatus and Gogatea serpentium) studied earlier. Inter-generic transformations of karyotypes were connected mainly with pericentric inversions in small chromosomes and robertsonian translocations in large elements of sets. The comparative karyometrical analysis of trematodes from related families showed the common origin of Cyathocotylidae, Diplostomatidae and Strigeidae. The main evolutionary mechanism in their speciation was found to be pericentric inversions in the small elements and robertsonian translocations, which were recognised only in the large chromosome group of Cyathocotylidae.

A new strigeid digenean, Strigea inflecta sp. nov., is described from the small intestine of the Red-legged Seriema, Cariama cristata (L.) (Gruiformes, Cariamidae) from Formosa Province, Argentina. This species is characterized by having a body plump, a cup-shaped forebody with a large opening, a sacciform hindbody, without a neck region and strongly curved dorsally, a poorly delimited copulatory bursa, wider than longer, a shallow and asymmetrical genital atrium, and a genital cone well delimited from body parenchyma, strongly muscular, inclined towards the surface ventral of the body. Another digenean species collected from Red-legged Seriema, Brachylaima yupanquii Freitas, Kohn et Ibáñez, 1967 (Brachylaimidae) is described with the addition of new morphological characters and morphometrical data. This species is reported for the first time in Argentina and C. cristata represents a new host record.

A total of eight species of furcocercous cercariae of four families (Strigeidae, Diplostomidae, Schistosomatidae and Sanguinicolidae), were found in 2005 in Lake Konnevesi in Central Finland in four snail species (Valvata macrostoma, Lymnaea stagnalis, Bathyomphalus contortus and Planorbarius corneus). Australapatemon burti (Miller, 1923), Australapatemon sp., Cotylurus brevis Dubois et Rausch, 1950, Cercaria spinulosa Ginetsinskaya, 1959 and Sanguinicola sp. are new species records for Finland. Ichthyocotylurus variegatus (Creplin, 1825) and Bilharziella polonica (Kowalewski, 1895) were first recorded as cercariae in Finland. The most common cercariae were A. burti (prevalence 13.3%) and Diplostomum pseudospathaceum Niewiadomska, 1984 (10.0%). Our study represents the first host record of Valvata macrostoma for larval stages of Australapatemon sp. and Sanguinicola sp.

Nine species of larval flukes, Notocotylus attenuatus, Echinostoma revolutum, Echinoparyphium aconiatum, Hypoderaeum conoideum, Plagiorchis elegans, Diplostomum pseudospathaceum, Australapatemon minor, Cotylurus sp., and Trichobilharzia ocellata were found in Lymnaea stagnalis in lake Kuuhankavesi (central Finland). Two species, P. elegans and E. aconiatum, are a new records from Finland and L. stagnalis was recognized as proper host for H. conoideum. In comparison with the records of Wikgren (1956) who found ten species of cercariae in L. stagnalis from the Tvärminne archipelago, our investigations revealed only five of these species: N. attenuatus, E. revolutum, D. pseudospathaceum (correct specific name for Wikgren’s D. spathaceum), Australapatemon minor (correct generic and specific names for Wikgren’s Apatemon gracilis) and T. ocellata. After Wikgren’s study on Tvärminne archipelago and Väyrynen from Northern Finland, the lake Kuuhankavesi (central Finland) are the third locality in Finland where larval trematodes have been studied.
