Two new species of the leafhopper tribe
The leafhopper genus
The specimens were obtained by sweep net and morphological terminology used in this work follows
Body length male 2.1-2.3 mm; female 2.2-2.4 mm. Vertex brownish-yellow, with one irregular spot near anterior margin (Fig.
The specific name is derived from the Latin word “
Crown fore margin strongly produced and angulate medially or weakly produced, broadly rounded apically. Vertex usually with pair of dark pre-apical spots or with large median apical patch. Pronotum pale or almost entirely dark or with dark posterior margin. Forewing with venation of clavum obscure.
Male pygofer lobe rounded or angulate, without dorsal macrosetae, with sparse long fine setae. Pygofer dorsal appendage movably articulated, ventral appendage absent. Subgenital plates free, lateral margin with angulate sub-basal projection, with 2–4 basal macrosetae and distinct marginal sub-basal rigid setae forming continuous row or with marginal sub-basal rigid setae restricted to basolateral angle. Style pre-apical lobe prominent. Style apex smooth, slender or truncate and expanded, third point absent. Aedeagus dorsal apodeme not expanded in lateral view; shaft curved dorsad, smooth or denticulate distally; apex broadened, truncate or acuminate in ventral view; ventral processes placed basally, well separated from shaft. Connective median anterior lobe broad, arms short.
Crown has anterior region yellow, while posterior area is yellow-milky, wider than pronotum. Face yellow, relatively long, with anteclypeus yellow (Fig.

The new species,
Male pygofer not extended to apex of subgenital plate. Pygofer lobe rounded. Pygofer ventro-apical membranous area well developed. Subgenital plate lateral margin with angulate sub-basal projection. Subgenital plates free. Style pre-apical lobe prominent. Style apex truncate and expanded or with 3 points. Aedeagus with pre-atrium shorter than shaft or with pre-atrium about as long as shaft. Aedeagus without dorsal process or with processes on dorsal apodeme. Connective median anterior lobe broad. Connective stem absent or very short, depressed.
