Phylogenetic reconstructions of Jebram 1986 [48] (a) and Todd 2000 [8] (b) including mapping of myoanatomical characters. First are listed the presence or absence of stolonal kenozooids (sk) and the size of the peristome (ps) followed by the six muscle sets described in this work. 1) body wall and derivates, 2) apertural muscles, 3) tentacle sheath muscles, 4) digestive tract muscles (here only cardia region mentioned, see text for details), 5) lophophoral base muscles, 6) retractor muscle. Abbreviations: bc – basal cystidal muscles (transitory? in Paludicelloidea and Arachnidioidea) or adult in stolons as stolonal transverse muscles (Walkerioidea), btm - basal transveral muscle of the lophophoral base, crm - continuous frontal ring muscle at the lophophoral base, cs – cardiac sphincter, d- diagonal tentacle sheath muscles, l – long persitome, l* - the long peristome forms the stolon in this group, lg – longitudinal tentacle sheath muscles, m – mixed (meaning both short and long peristomes are present), p – parietal muscles, pb – parietovaginal band, pd – parietodiaphragmatic muscle, ps – peristome, pro – proventriculus, pv – parietovestibular muscles, r - rosette-like pore complexes, s – short peristome, sk - stolonal kenozooids, sm – smooth retractor muscles, st – striated retractor muscles
