| description |
A large species with a broad, tall, rounded pronotal crest that slightly angles forward. The top of the pronotal crest is edged in red, and the posterior edge is yellow. The pronotum itself is usually a light brown color, but some individuals can have a greenish tint; there may be some light maculations across the pronotum in some specimens as well. The wings have a smoky tip, and the legs are concolorous with the pronotum. Males are 8-9 mm long while females are 9-10 mm (FSCA).
Nymphs are pale, mottled with gray and brown, and have a pronounced bulging "knob" on the thorax: 1, FSCA |

| comments |
This species may be most confused with Archasia belfragei, as they both have similarly shaped pronotums. However, T. extrema tends to be brownish in color while A. belfragei is greenish. But there are also slight differences in the shape of the pronotum. With A. belfragei, the pronotum is either broad or moderate in width, but there is a somewhat even, gradual curve starting from the rear to the highest point of the crest itself. With T. extrema, the pronotum is always broad and there is a kink in the crest before it sharply curves upward. This kink is largely absent or heavily reduced in A. belfragei. |
