Subgenus Phyllotettix Hancock, 1902b

Type species.

Acrydium compressum Thunberg, 1815

Composition and distribution

(Figs 1 , 2 ). The nominotypical subgenus includes only two species, P. compressus (Thunberg, 1815) and P. foliatus (Hancock, 1902a). These two species are very similar and may represent (subspecies of) a single species. The two species are endemic to Jamaica.

Diagnosis

(Figs 1 , 3 ). In lateral view, the posterior margin of the pronotal crest is excised and/or convex (in Rhombotettix Rhombotettix subgen. nov., it is obliquely projected and undulated); the pronotum caudally barely reaches the hind knees (reaching behind the hind knees in Rhombotettix Rhombotettix subgen. nov.).

Figures

Figure 1. Diversity of the Caribbean Pygmy Jumping Leaves, tribe Choriphyllini, genera Choriphyllum and Phyllotettix. All the specimens with available photographs are shown, representing the first variability assessment for the species of these genera. The scale bar represents 5 millimetres.

Figure 2. Biogeography of the Caribbean Jumping Leaves (Cladonotinae, Choriphyllini). Biogeographic data of the tribe Choriphyllini is scarce. The distribution map of the six species belonging to this leaf-like tribe has the distribution of three species missing, as no localities are known.

Figure 3. Annotated schematic pictorial key to genera and species of Choriphyllini. Specimens are not to scale; for size comparison see Fig. 1. The red line shows the position of the highest point of the pronotal crest. The blue arrow points to the anterior margin of the pronotum; the green arrow points to the posterior pronotal tip; and the purple arrow points to the caudal margin of the pronotal crest. Shown are silhouettes of the type specimens of each species. For C. sagrai, shown is the silhouette of Serville's (1838) drawing of the holotype. The capital sinus is marked in red and pointed out in grey.
