Rauiella scita
Rauiella scita is more likely to be confused with Leskea (Leskeaceae) than with any other Thuidiaceae. However, the abundant paraphyllia and multipapillose laminal cells distinguish R. scita. As in R. praelonga, the distal portion of the costa of the branch leaves is covered with laminal cells, but in R. scita the apical cell of the branch leaves is truncate and multipapillose, unlike the smooth, pointed apical cell in R. praelonga.
