Taxonomy Kupriyanova et al. (2015:283): "Hydroides externispina is easily recognisable because of its two large, strongly curved inwards dorsal verticil spines as well as dark curved outwards lateral and external spinules. This species can be confused with H. tambalagamensis Pillai, 1961 because of similar dark curved outwards lateral spinules on the verticil spines in both species. H. externispina differs from H. tambalagamensis by the presence of two enlarged curved inwards dorsal verticil spines, whereas in H. tambalagamensis all verticil spines are of the same size. The presence of these two large inwards-curved dorsal verticil spines makes H. externispina similar to H. glasbyi Sun et al., 2015, however, the latter species lacks conspicuous externally curved lateral spinules on smaller verticil spines."
