It is clear that in herpyllobiids the shape of the ectosoma of the adult female can vary markedly according to their individual reproductive state, so it is unlikely to be reliably diagnostic of species identity. So, despite these differences noted above in material from particular hosts, it will be necessary to obtain more data, preferably including molecular sequence data, before the taxonomic significance of these differences in ectosomal shape can be ascertained.</paragraph>
