The leafhopper genus
Two new species found at Bijie City and Shibing County, Guizhou Province, China are described and illustrated,
The leafhopper genus
The characteristics of
Male pygofer lobe with hind margin sleeked or truncated slightly, basal lateral angle usually with macrosetae, sometimes absent and scattered a few fine setae in outer lateral surface. Pygofer dorsal appendage articulated to pygofer lobe with ventral appendage absent. Subgenital plate with some macrosetae in mid-ventral part, broad basally and sometimes terminal half tapering abruptly; row of stout setae along upper margin from sub-base to apex. Apex of style pointed, bifid, foot-shaped or otherwise modified. Aedeagus with dorsal apodeme well developed; aedeagal shaft tubular; gonopore sub-basal to subapical on ventral surface. Connective lateral arms long, Y- or V-shaped.
All specimens in this study were collected by the sweeping-net method. Morphological terminology used follows
Body brownish-black. Head brownish-yellow, with pair of small dark brown apical spots (Fig.
The new species is named from the Latin word “
This species can be distinguished from other species in this genus by the unique characters of the aedeagus: the aedeagal shaft with serrated marginal lamellae on both sides of apex, pair of small curved processes subapically; short dorsal apodeme and long prearium.
Male length 2.8 mm (including wing). Body yellowish. Vertex brownish-yellow, with pair of small dark brown apical spots (Fig.
The new species is named from the Latin word “
