' known only from sclerites; these have internal chambers that are sub-perpendicular to the central canal, to which they are connected by narrow channels. The chambers are the same diameter, ~40 µm, as the longitudinal canals in '' Australohalkieria''; their greater number and arrangement as lateral rather than longitudinal bodies reflects the greater size of the ''Sinosachites'' sclerites, which measure about 1–2 mm in length. The sclerites are probably synonymous with ''
