Taxon discussion

This species is easily recognizable by the 2 - 5 pairs of pinnae, cuneate at base, and tubular yellow to orange glands on the receptacle ( Smith 1983). The presence of these glands is shared with T. (Meniscium) andreana  (Sodiro) C.V.Morton, the closest species to T. (Meniscium) arcana  ( Smith 1983).
