Molecular phylogenetic hypotheses of the superfamily Phillinoidea showing relationships between Aglajidae genera, based on a concatenated dataset of four markers (COI, 16S, H3, 28S). Outgroup taxa are collapsed by their families, aglajid taxa except Aglaona gen. nov. by their genera. A, Bayesian inference, posterior probabilities higher than 0.9 are shown in the respective node. B, maximum likelihood; bootstrap values higher than 60% are shown in the respective nodes.Published as part of Chaban, Elena M., Ekimova, Irina A., Schepetov, Dimitry M. & Chernyshev, Alexei V., 2022, The new genus Aglaona: the first abyssal aglajid (Heterobranchia: Cephalaspidea: Aglajidae) with a description of two new species from the north-western Pacific Ocean, pp. 198-214 in Zoological Journal of the Linnean Society 196 on page 202, DOI: 10.1093/zoolinnean/zlab115, http://zenodo.org/record/703528

Aglajidae Pilsbry 1895
No full textFAMILY AGLAJIDAE PILSBRY, 1895 (1847) Diagnosis (modified from Zamora-Silva & Malaquias, 2018): Shell internal, typically reduced, but welldeveloped bulloid in some species. Mantle typically with caudal asymmetrical lobes. Gizzard plates absent. Radula typically absent; when present, radular formula 1:0:1 or 2:1:0:1:2; inner laterals bearing one or two large or many small denticles on inner border. Penial papilla with chitinous stylet or plate. Yellow gland present (in histologically studied specimens). Sensory mound on anterior part of head with numerous bristles over surface, or without bristles in some species. Fifteen genera have been included in the family (MolluscaBase eds, 2021a) and another new genus, Aglaona, which is described below.Published as part of Chaban, Elena M., Ekimova, Irina A., Schepetov, Dimitry M. & Chernyshev, Alexei V., 2022, The new genus Aglaona: the first abyssal aglajid (Heterobranchia: Cephalaspidea: Aglajidae) with a description of two new species from the north-western Pacific Ocean, pp. 198-214 in Zoological Journal of the Linnean Society 196 on page 204, DOI: 10.1093/zoolinnean/zlab115, http://zenodo.org/record/703528
