“…By employing sequence data from four to five nuclear genomic loci (nuc 28S rDNA [
LSU], RNA polymerase largest [
RPB1 ] and second largest subunit [
RPB2 ], translation elongation factor 1-alpha [
EF-1α ], and for particular groups also nuc rDNA ITS1-5.8S-ITS2 [ITS]) and principles of genealogical concordance phylogenetic species recognition (
GCPSR;
Taylor et al 2000),
O’Donnell et al (2011) distinguished 41 phylogenetic species (phylospecies) in three major clades across the globe: 24 in the Elata Clade, 16 in the Esculenta Clade and one species in the
Rufobrunnea Clade. In parallel or later, many new phylospecies were distinguished by several authors, who did not always utilize the multigene approach and/or basic phylogenetic principles (such as monophyly), not to speak of
GCPSR (
Taşkın et al 2010,
2012;
Du et al 2012a;
Elliott et al 2014;
Pildain et al 2014;
Loizides et al 2016;
Voitk et al 2016a). Because binominal names can be unambiguously assigned to only a part of the phylospecies, they are usually (but not by all authors) denoted by a clade abbreviation followed by an Arabic number (Mel-1 to Mel-38 for the Elata Clade and Mes-1 to Mes-28 for the Esculenta Clade;
Taşkın et al 2010;
O’Donnell et al 2011).…”
