Lyonsiellidae Dall 1895

Notes

Considered one of the rarest groups amongst Anomalodesmata , members of Lyonsiellidae are generally poorly sampled and under-represented in phylogenetic analyses (e. g., Combosch et al. 2017). Consequently, its family status has been debated for the past two decades. Dreyer et al. (2003) and Harper et al. (2006), mainly using a molecular approach, cast doubt on the monophyly of the Lyonsiellidae . Coan and Valentich-Scott (2012), for example, taking into account mainly shell features, considered lyonsiellids as a subfamily, Lyonsiellinae under family Verticordiidae . Crouch et al. (2021), in a budding-based calibrations approach, using a combination of molecular and morphological studies, corroborated the family level of Lyonsiellidae . More recently, however, Machado and Passos (2022) brought together for the first-time morphological characters from representatives of all Anomalodesmata families in a cladistic approach, recovering the Lyonsiellidae as polyphyletic.
