Systematics: This species is very similar to T. gracile in the characters of the trullae and in having no dorsal macroducts scattered on the pygidium. It is, however, remarkably different not only from T. gracile but also from the other known species in having the theca elaborately crenate on the lateral margins. (Takagi, 2022)
Structure: Theca ca.3.0–3.9 times [n=10] as long as wide when fully formed, rounded on both anterior and posterior ends, subparallel and elaborately crenate on lateral margins. Antennae each represented by a thick seta arising from a shallow dermal depression, there being no tubercle to bear it. (Takagi, 2022) In this species, the first-instar nymphs of both sexes are provided with long marginal setae around the body probably for wind-dispersal. (Takagi, 2022)
