Lyonsiella G. O. Sars 1872 View in CoL
Type species: Lyonsiella abyssicola (G. O. Sars, 1872) View in CoL .
Composition: Twenty valid species, of which 19 are databased ( MolluscaBase 2024) and one, Lyonsiella illaesa Machado & Sigwart , sp. nov., is newly described here.
Diagnosis: Shell small to medium size (1 to ~ 25 mm in length), thin, usually inflated, quadrate to subrectangular, inequilateral, right valve generally larger than left valve with valve margins flexuous, slightly overlapping; outer surface granular or with spinules with sparse radial lirae or folds, frequently with adhering particles; hinge plate feeble, edentate, but anterior dorsal margin of left valve may be thickened; lithodesma elongate. Ctenidium reduced to few filaments aligned horizontally in pallial cavity, sometimes outer demibranch or its ascending lamella absent. Inhalant siphon cone-shaped with eversible capacity, usually surrounded by small and arborescent-shape tentacles. Taenioid muscles sometimes well developed. Usually hermaphrodite (after Allen and Turner (1974), Poutiers and Bernard (1995), Coan and Valentich-Scott (2012)).
