Type locality.

Jamaica, without specified location ( Thunberg 1815).

Type specimens.

Holotype ♂ of Acridium compressum . Jamaica • 1 ♂; UZIU. Holotype photographs are available on the OSF, http://orthoptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=1100598).

Other specimens.

Jamaica • 1 ♀; Blue Mountains; 18.054489°N, 76.600555°W; 14 May 2022; Damany Calder leg.; iNaturalist ID: 117405730. Four photographs are available at https://www.inaturalist.org/observations/117405730).

Jamaica • 1 ♀; MfN.

Distribution

(Fig. 2 ). Jamaican Bitten Jumping Leaf is endemic to Jamaica. Until recently, no specified localities were known, but now, after the iNaturalist observation of a living individual (https://www.inaturalist.org/observations/117405730), we know for sure that the species inhabits the Blue Mountains range NE of Kingston. Phyllotettix foliatus has been reported from the same mountain range (see below).

Diagnosis

(Figs 1 , 3 ). Very similar to Phyllotettix foliatus , which is a member of the same species group. Separated by the narrow and sharp highest point of the pronotum (wide and oblique in P. foliatus ) and after it, the posterior margin of the pronotum is strongly convex (almost straight in P. foliatus ).

Measurements.

See Table 1 .

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.

Figure 5. Hancock's plate I from the " Tettigidae of North America " shows leaf-like Caribbean species under the numbers 1), 2) and 7), but has many taxonomic and nomenclatural errors. 1) - Phyllotettix foliatus (= female holotype of Hancock's Choriphyllum foliatum), 2) - Phyllotettix rhombeus (= Hancock's Choriphyllum westwoodi), 7) - Choriphyllum saussurei. (= Hancock's Phyllonotus saussurei). Source: Biodiversity Heritage Library, available at https: // www. biodiversitylibrary. org / item / 25899 # page / 10.

Figure 6. The evidence of synonymy of Choriphyllum westwoodi Hancock, 1902 a with Phyllotettix rhombeus (Felton, 1965); A. Felton's (1765) original drawing of Cicada rhombea; B. Felton's and Westwood's drawings of specimens of Phyllotettix rhombeus overlapped, showing they are almost identical; C. Westwood's (1839) drawing of a new record of Hymenotes rhombea; D. Hancock's (1902 a) establishment of the name " Choriphyllum westwoodi "; E. Hancock's (1902 a) drawing of Choriphyllum westwoodi can be regarded as type specimen designation. All specimens undoubtedly show Phyllotettix rhombeus (see Figs 1 - 3 for comparison).
