Phyllotettix (Rhombotettix) plagiatus (Walker, 1871), comb. nov.

Choriphyllum plagiatum Walker, 1871: 845 (original description); Thomas 1873: 245 (brief re-description); Hancock 1907: 13 (included in the catalogue); Kirby 1910.: 6 (listed in the catalogue); Silva et al. 2019: 3, 6, 7 (status of the types, re-description, included in the key, holotype photograph). Taxonomic and nomenclatural history.

Phyllonotus plagiatum Hancock, 1902: 45-46 (included in the key, brief re-description).

Type locality.

Jamaica, without specified locality ( Walker 1871).

Type specimen.

Holotype of Choriphyllum plagiatum . Jamaica • 1 ♂; BMNH. Photograph on the OSF, http://orthoptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=1100630.

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.

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.
