Moser, 1925
Only a single anterior and posterior nectophore produced, although the latter may be reduced or suppressed entirely. Anterior nectophore usually apically pointed and usually larger than posterior one. The bracts of the free-swimming eudoxids usually are helmet-shaped. The bulk of the diphyid species is contained in this subfamily divided amongst about 7 genera, with most being included in the catch-all genus Lensia. In several species the posterior nectophore is either not developed or has not been described. Some, particularly within the genus Lensia, are very difficult to distinguish specifically. Similarly many eudoxid stages remain unknown. It is, therefore, impossible to give a comprehensive description for every part of every species.
