Description.

Male (Figs 9A , 10A , 11A, C, E, G ). Body size small. Head small, slightly broader than anterior margin of pronotum. Frons significantly narrower than antennal scape. Eyes large and protruding laterally. Three apical joints of maxillary palpi distinctly elongate, and fifth joint apically truncated. Pronotum transverse, posterior margin conspicuously broader than anterior one. Tegmina extending over abdominal apex, and six primary veins staggered with many transverse veins between them. Visible part of hindwing is half length of tegmen. Internal tympanum large and long-oval, external one shaped as a small pit. Hind tibia bearing three dorsal spurs on each side.

Genitalia (Fig. 12A-C ). Lateral lobes of epiphallus stick-like and apically blunt. In dorsal view, these lobes are straight and hirsute on the inner margin. Ectoparamere bifurcated as two rectangular branches, and the upper larger than lower one. Rami arcuate, very long, and surpass ectophallic and endophallic apodemes.

Female (Figs 9B , 10B , 11B, D, F ). Resembles male. Body size slightly larger than male. Longitudinal veins of tegmen parallel and forming rectangular cells with some pale transverse veins (filled yellowish brown). Ovipositor falcate and similar to the species described above.

Coloration. Body greenish-brown. Head and pronotum brown. Most of the apical three joints of the maxillary pale and proximally darkly color. Tegmen yellowish-brown with green veins. The hind femur bearing an irregular dark pattern.

Measurements. Male: BL 5.95-6.26, PL 0.76-0.86, TL 4.74-4.96, HFL 4.26. Female: BL 5.64-6.15, PL 0.78-0.88, TL 4.74-5.20, HFL 4.45-4.88, OL 1.94-2.19.

Etymology.

The name refers to the green veins of the species.

Distribution

(Fig. 1 ). China (Hainan, Zhejiang, Yunnan).

Remarks.

Specimens of this species were identified as A. fujianensis (= S. fujianensis ) by He et al. (2010), but this is incorrect. The true A. fujianensis bears brown veins and a rounded ectoparamere apex, whereas those assumed to be A. fujianensis bear green veins and a squared ectoparamere apex. This species is similar with Amusurgus (Amusurgus) xanthoneurus (Chopard, 1940) in having green veins and the pattern of legs and cerci, but differs in the color of the apex of hind femur (black-brown in A. xanthoneurus vs yellow-white in F. viridipennis ) and in the distance between Cu1 and Cu2 of the tegmen in females (extremely narrow in A. xanthoneurus vs relatively wide in F. viridipennis ).
