An unusually dark typhlocybine leafhopper (
Song Y, Yuan Z, Jiang J (2021) A new, unusually dark, typhlocybine leafhopper (Hemiptera, Cicadellidae, Typhlocybinae, Erythroneurini) from China. ZooKeys 1042: 35–40.
Morphological terminology used in this work follows
Head, pronotum and mesonotum mainly blackish brown. Face brown marked with yellow. Forewings brownish hyaline. Legs yellow. Abdomen dark brown with margins of segments yellow.
Head narrower than pronotum, short; vertex with coronal suture long and distinct; face with frontoclypeus relatively slender, anteclypeus broad, nearly pentagonal. Pronotum broad, with pyramidal anterior margin; posterior margin slightly concave. Forewing with claval vein distinct; outer apical cell much more than twice as long as wide. Hind wing with RA vein present.
Male abdominal apodemes small, not exceeding 3rd sternite.
Male genitalia with pygofer lobe with posterior margin indented apically; with few fine setae and several microtrichia scattered on dorsal and ventral parts in caudal half; with elongate articulated dorsal appendage, extended to near pygofer apex. Subgenital plate short and robust, with few macrosetae laterally in apical half and numerous short stout setae along upper margin and on distal disc in lateral view; several microtrichia on outer surface medially. Style with foot-like apex, with preapical lobe greatly enlarged. Aedeagus relatively small and simple, preatrium and dorsal apodeme well developed, the latter with dorso-lateral corners greatly extended; gonopore subapical on ventral surface. Connective Y-shaped, with stem similar in length to arms, upturned apically; central lobe small.
The genus is named after the locality of the type species, Shibing. The gender is feminine.
China (Guizhou).
The new genus belongs to
Body length, males 2.6–2.7 mm, females 2.7–2.8 mm.
Head, pronotum and mesonotum mainly blackish brown (Fig.
Male abdominal sternal apodemes short, not extending to hind margin of 3rd segment (Fig.
Male genitalia as in generic description. Pygofer not extended to apex of subgenital plate, articulated dorsal appendage slightly curved distally (Fig.
The species is named for its unusual dark color, from the Latin niger, black.
This species can be distinguished by external and male genitalia characters (see generic remarks).
