Subfamily Hesioninae Grube, 1850

Summers et al. (2015) modified the status of the subfamilies and tribes in Hesionidae and concluded that Hesioninae includes only the tribe Hesionini, but because there are no other tribe within the subfamily, Hesionini becomes redundant. Pleijel (1998: 107) diagnosed the Hesionini with 21 segments, body short, stout, cuticle with metallic lustre, nuchal organs coalescent, posterior prostomial incision distinct, aciculae blackish, neuropodial lobes rectangular, neurochaetae bidentate; and pharynx without papillae. Pleijel (1998) included five genera: Dalhousiella McIntosh, 1901 (see Salazar-Vallejo & Rizzo 2020), Hesione Savigny in Lamarck, 1818, Leocrates Kinberg, 1866, Leocratides Ehlers, 1908 and Wesenbergia Hartman, 1955; the latter has been replaced by Elisesione Salazar- Vallejo, 2016. After the reinstatement of Lamprophaea Grube, 1867 (spelling modified, see below), and Dalhousia McIntosh, 1885 and by regarding the other morphological patterns, the tribe would include 7 genera, plus three newly proposed genera. They can be separated with the following key.
