Sentence:  It is clear, therefore, where any <WSD>epitype</WSD>, selected as an interpretive type, should be sought. The selection of an <WSD>epitype</WSD>, in the absence of type or authentic material, would be important, for any further molecular work will need to have available a culture of the type species of the genus which has some nomenclatural standing, i.e. a culture derived from the <WSD>epitype</WSD>. 
Meaning of the word marked with <WSD> tags:  An additional, clarifying type (specimen or illustration) of a species or lower-order taxon, provided when the holotype and paratypes from the original classification are demonstrably ambiguous or insufficient.
