| Summary: | FIGURE 7. Ontogenetic integration of morphological data and molecular phylogeny implying a common ancestral ontogenetic cycle of the family Trinchesiidae with veliger larva, earlier postlarval stages with oral veil and 1-2 cerata per side and adult stage with fewer cerata (less than six anterior ceratal rows), without notal edge and with acleioproctic anus. Evolutionary derived adult stages of the type species of the genera Phestilla, Catriona, Tenellia, Trinchesia, Diaphoreolis, Zelentia of the family Trinchesiidae, respectively. A. Phestilla melanobrachia Bergh, 1874. B. Catriona aurantia (Alder et Hancok, 1842), reinstated. C. Tenellia adspersa (Nordmann, 1845). D. Trinchesia caerulea (Montagu, 1804). E. Diaphoreolis viridis (Forbes, 1840). F. Zelentia pustulata (Alder et Hancock, 1854) comb. nov. I. Dorsal view and cerata cross section. II. Ventral view, anterior part. III. Radula, SEM. IV. Masticatory process of jaw, SEM. V. Penis with stylet, SEM. Abbreviations: cn, cnidosac; strikethrough cn, absence of cnidosac; st, penial stylet; Scale bars: AIII—20 µm, AIV—50 µm, AV—5 µm, BIII, BV, CIII, CIV, CV, DV, FIV, FV—10 µm, BIV, DIV, EIV, EV—20 µm, DIII, EIII, FIII—30 µm. Molecular phylogeny from Cella et al. (2016), graphically modified. All images by T.A. Korshunova and A.V. Martynov, except for AI – by O.V.
