AbstractDigenea Carus, 1863 represent a highly diverse group of parasitic platyhelminths that infect all major vertebrate groups as definitive hosts. Morphology is the cornerstone of digenean systematics, but molecular markers have been instrumental in searching for a stable classification system of the subclass and in establishing more accurate species limits. The first comprehensive molecular phylogenetic tree of Digenea published in 2003 used two nuclear rRNA genes (ssrDNA = 18S rDNA and lsrDNA = 28S rDNA) and was based on 163 taxa representing 77 nominal families, resulting in a widely accepted phylogenetic classification. The genetic library for the 28S rRNA gene has increased steadily over the last 15 years because this marker possesses a strong phylogenetic signal to resolve sister-group relationships among species and to infer phylogenetic relationships at higher levels of the taxonomic hierarchy. Here, we have updated the database of 18S and 28S rRNA genes until December 2017, we have added newly generated 28S rDNA sequences and we have reassessed phylogenetic relationships to test the current higher-level classification of digeneans (at the subordinal and subfamilial levels). The new dataset consisted of 1077 digenean taxa allocated to 106 nominal families for 28S and 419 taxa in 98 families for 18S. Overall, the results were consistent with previous higher-level classification schemes, and most superfamilies and suborders were recovered as monophyletic assemblages. With the advancement of next-generation sequencing (NGS) technologies, new phylogenetic hypotheses from complete mitochondrial genomes have been proposed, although their power to resolve deep levels of trees remains controversial. Since data from NGS methods are replacing other widely used markers for phylogenetic analyses, it is timely to reassess the phylogenetic relationships of digeneans with conventional nuclear rRNA genes, and to use the new analysis to test the performance of genomic information gathered from NGS, e.g. mitogenomes, to infer higher-level relationships of this group of parasitic platyhelminths.

Hierarchic System

To establish a hierarchic classification system, ranks cannot be defined by the exclusive and inflexible application of phylogenetic parameters. Because both stability and practicality are prerequisites for a successful system, decisions about the delineation of genera must be made by combining phylogenetic coherency with unifying phenotypic properties of taxonomic value consistent with the needs of a hierarchic system. The phylogenetic depth (age) of a genus has no influence on the decision as long as the members of the genus can be reliably identified as such. The description of those higher taxa that are not easily definable today because of the lack of common phenotypic properties must be postponed until new insights are available. In the end this approach will be both phylogenetic and practical, thus avoiding the use of two classification systems.

Avena laevigata Schur (1860: 72) belongs to the taxonomically difficult group of perennial oats whose phylogenetic relationships, systematics, and nomenclature have been reconsidered many times (Holub 1958, 1962, Gervais 1973, Röser 1989, Lange 1995, Conti et al. 2005, Röser et al. 2009, Romero-Zarco 2011). It is affiliated with the generic name Avenula (Dumortier 1824: 122) Dumortier (1868: 68), a taxon accepted in the worldwide phylogenetic classification of the Poaceae (Soreng et al. 2015) and is the basionym of the accepted subspecies name Avenula pubescens (Hudson 1762: 42) Dumortier (1868: 68) subsp. laevigata (Schur) Holub (1976: 295) (Euro+Med 2006 onwards) distributed in the western and southern Alps as well as the southern and eastern Carpathians (Dixon 1991). The nomenclatural type of Avena laevigata (and so that of Avenula pubescens subsp. laevigata) is unknown, hence typification of this name is necessary (McNeill et al. 2012).
