In the present study the presence of lysenin and lysenin-related protein 2 (LRP-2, known also as fetidin) was detected in coelomocytes retrieved from all investigated adult specimens of E. andrei, and E. fetida. They were accompanied by LRP-3 and LRP-1 in some specimens of E. andrei and E. fetida, respectively. Lysenins were not observed in a third composting lumbricid species, Dendrobaena veneta, which served as a convenient negative reference for techniques and procedures used in the study. The pore-forming potential of soluble and cellular fractions of coelomic fluid was studied towards sheep red blood cells and sphingomyelin-rich liposomes. After experimental depletion the potential was restored in parallel with rest...

The morphology of male and female reproductive organs of H. maltzani did not differ within studied populations or in comparison with closely related species. In contrast, analysis of shell morphology revealed substantial variation not supported by the genetic data. Genetics results showed surprisingly low differentiation between all Cretan populations and also mainland populations of Heleobia. They also showed that H. maltzani is conspecific with four other European species of Heleobia, thus implying that there is only one species of brackish-water Heleobia in Europe. Such a low level of genotypic differentiation is unusual for typical island species and is most probably the consequence of recent colonization of Crete. Possible scenarios of such processes are discussed.

To address the above issues, the morphology and the mitochondrial genes—cytochrome oxidase sub-unit I (COI) and ribosomal 16S—and nuclear genes—ribo-somal 18S, 28S and histone 3 (H3)—were analysed. COI and COI+16S rRNA+18S datasets gave trees with identical topology in both ML and Bayesian inference. The 24 studied populations of Pseudamnicola form 16 clades, each of them generally having low levels of intrapopulation genetic differentiation. The generalised mixed Yule coalescent (GMYC) procedure and the Automatic Barcode Gap Discovery (ABGD) analysis for COI identified 16 Pseudamnicola entities coinciding with clades of the ML tree based on 44 haplotypes and 189 sequences. The present pattern of diversity , together with dating of divergence time, reflects a short story of colonisation/recolonisation, supported by the Late Pleistocene land bridges, rather than the consequences of earlier geological events. The principal component analysis (PCA) on the shells of the molecularly distinct clades showed differences, although variability ranges often overlap. Female reproductive organs showed no differences between the clades, and penile characters differed only in some cases.
