Systematics: This species is easily recognizable in having a slender theca, which is also peculiarly characterized in the head transparent at the anterior end. On the other hand, it is hardly distinguishable from the species, T. crenatum, by the use of pygidial characters, while the latter, too, has a remarkable theca, which is elaborately crenate on the lateral margins. (Takagi, 2022)
Structure: Theca slender, 6.8–9.3 times as long as wide when fully formed; vertex rounded; posterior end (posterior margin of abd I) truncate; anterior extremity (area enclosed approximately by vertical margin) transparent (not dark-coloured), the other dorsal surface of the theca sclerotized and dark-coloured. Antennae each represented by a thick seta arising from a shallow dermal depression, there being no tubercle to bear the seta. (Takagi, 2022)
