Genus Phyllotettix Hancock, 1902b

Phyllonotus = Phyllonotus Hancock, 1902a (preoccupied with Phyllonotus Swainson, 1833, Mollusca).

Zaphyllonotum = Zaphyllonotum Caudell, 1909 (type species Choriphyllum foliatum Hancock = Phyllotettix foliatus ).

Type species.

Acrydium compressum Thunberg, 1815 (= Phyllotettix compressus ).

Composition and distribution

(Figs 1 , 2 ). Four species are assigned to two subgenera, each with two species. The nominotypical genus includes P. (P.) compressus and P. (P.) foliatus , while the Phyllotettix Rhombotettix subgen. nov. includes P. (R.) plagiatus comb. nov. and P. (R.) rhombeus . All species are endemic to Jamaica.

Diagnosis

(Figs 1 , 3 ). The anterior margin of the pronotum is undulated (smooth in Choriphyllum ). The capital sinus is short, shallow and wide. The highest point of the pronotum is behind the middle (before the middle or in the middle in Choriphyllum ). Apex of the pronotum oblique or sharp (strongly truncated in Choriphyllum ).

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.
