This species was described from southwest Thailand by Chantanaorrhapint & Seelanan (2021). It was collected in July 2013 and could not be retrieved yet, despite of revisits to the location in 2015, 2017, 2018 and 2020. Thismia clavigeroides is most similar to T. clavigera due to the form of the mitre with long erect appandages, connective and stigma charakteristics. However, T. clavigeroides has much larger flowers and longer appandages, it is whitish to grey-brown (vs. yellow-orange or pinkish red depending on the collection of T. clavigera) and its outer perianth lobes are reflexed (vs. shorter and erect in T. clavigera). Also similar in overall appearance are T. sumatrana, T. betung-kerihunensis and T. kelantanensis.
