Neuterthron Ding

Neuterthron Ding, 2006: 443 . Type species: Neuterthron hamuliferum Ding, 2006 , by original designation.

Diagnosis. Small delphacids. Head quadrate; fastigium obtuse angled; median facial carina forked at base of frons. Calcar foliate, tectiform, with many small, black-tipped teeth on lateral margin. Pygofer with laterodorsal angles strongly produced and inflected ventrad. Genital diaphragm with dorsal margin incised medially, ventrocaudally prolonged into a process that surpasses posterior margin of pygofer. Aedeagus tubular and ornamented with teeth. Parameres fairly long, reaching to the level of anal segment. Anal segment ring-like, sunk deeply in dorsal pygofer emargination.

Remarks: Neuterthron is similar to Terthron Fennah (1965) using the key of Ding (2006). It differs from the latter mainly in the structure of the male genitalia. In Neuterthron the laterodorsal angles of the pygofer is strongly produced and inflected ventrad; The genital diaphragm is ventrocaudally prolonged into a process that surpasses the posterior margin of the pygofer and the aedeagus lacks a ventrobasal projection. Distribution. China (Zhejiang, Sichuan, Guizhou, Yunnan, Hubei, Shaanxi).
