Two new species,
The leafhopper genus
Type species:
Main characteristics of genus
Male pygofer lobe with hind margin sleeked or truncated slightly, cephalo-ventral angle usually with macrosetae, sometimes absent and scattered with a few fine setae in outer lateral surface. Pygofer dorsal appendage movably articulated to pygofer lobe with ventral appendage absent. Subgenital plate broad basally, tapering to middle, subparallel-sided from middle to apex and rounded apically; with some macrosetae in mid-ventral part; row of stout setae along upper margin almost from subbase to apex. Style with shape of apex various, bifid, foot-shaped or otherwise modified. Aedeagus with aedeagal shaft tubular; gonopore sub-basal to subapical on ventral surface; with or without well-developed pre-atrial processes, dorsal apodeme well developed. Connective lateral arms long Y- or V-shaped.
The specimen was collected by the sweeping-net method. Morphological terminology used follows
Body brownish-black. Head milky yellow (Fig.
Pygofer lobe broad, with five macroseta at cephalo-ventral angle of lobe and one macroseta at junction area with anal tube (Fig.
The specific epithet is derived from the Latin word “
This species is similar to
Body brownish-yellow (Fig.
Subgenital plate slightly concave near middle area, with three macrosetae on outer surface (Fig.
The new species is named from the Latin word “
