Status A clear separation between the Encope (Echinadesma) and Encope (Encope) is difficult because all intermediate states between a continuous and fully disjunct interambulacrum 5 exist. Separation of the disjunct forms seems thus arbitrary and Echinadesma is considered as junior synonym of Encope in The Echinoid Directory. Recently, Coppard & Lessios (2017) performed a multi-gene phylogeographic analysis of the genus Encope. While they did not specifically discuss the status of the subgenus Echniodesma, they commented that Phelan's subdivision of the genus Encope was not supported by the molecular phylogeny. According to their results E. emarginata and E. grandis are part of one clade, which is incompatible with the topology implied by the subgeneric classification of Phelan. Clearly disjunction of interambulacrum 5 (the diagnostic character of Echinadesma) evolved multiple times in Encope, making the subgenus Echinadesma (when defined upon this feature) polyphyletic.
