Key visual features: While both G. lapislazula and D. haematogaster have rounded nectophores and red-pigmented gastrozooids, D. haematogaster can be distinguished by presence of bracts, disjunct pedicular canal, and a substantial portion of the somatocyst remains in contact with the upper wall of the hydroecium.
