  Comment: 'Beklemishev [...] used the class Graptolithoidea with the orders Rhabdopleuroidea and Cephalodiscoidea and including the graptolite orders Stolonoidea, Camaroidea, Tuboidea, Dendroidea and Graptoloidea. Beklemishev, thus, did not include the extant pterobranchs in the graptolites, but extended the concept of the 'graptolites' and synonymised the Pterobranchia with his more extensive class Graptolitoidea. Some graptolite workers followed his classification (see discussion in Urbanek 1986). It is here preferred to keep the name Pterobranchia as an umbrella for all hemichordates secreting a tubarium (termed rhabdosome in planktic Graptoloidea) and use the term Graptolithina for its colonial members (following Mitchell et al. 2013)' (Maletz, 2014)
