Heterocoryne Wedler & Larson, 1986

Diagnosis: Hydroid colony stolonal; hydrocaulus unbranched; hydranth vasiform, with one whorl of long capitate tentacles and one whorl of tentacles that are composed of two to four parallel, partially-fused capitate tentacles. Gonophores single, on short pedicel, among upper whorl of simple capitate tentacles. Gonophores developing into eumedusoids.

Genetic diagnosis: 87 molecular diagnostic characters differentiate Heterocoryne from other genera in the family, specifically 21 in the 16S, 23 in the COX1, 33 in the COX3, 6 in the 18S, and 4 in the 28S ( table 2 ).

Remarks: Heterocoryne is a monotypic genus.
