Distribution

(Fig. 2). The Jamaican Triangular Jumping Leaf is endemic to Jamaica, no precise localities are known.

Diagnosis

(Figs 1, 3). Similar to Phyllotettix (Rhombotettix) rhombeus, but easily separated by the shape of the anterior and posterior margins of the pronotum, as seen in the lateral view. The most produced anterior part of the pronotum is just above the head, not the one on the dorsal margin as in R. rhombeus . The pronotal crest is triangular in shape and gradually descends from the highest point towards the posterior tip of the pronotum.
