Etymology.­ The species name refers to ectoparamere armed with multiple curved structures.

Description.­Male: Body size small for the genus. Head slightly narrower than pronotum. Vertex broad and flattened, densely pubescent. Frontal rostrum slightly wider than antennal scape; and slightly convex in front view, inclined dorsally and ventrally. Median ocellus smallest of the three, ovoid; lateral ocellus transversely ovoid. Eyes slightly convex. Clypeus and labrum shiny; clypeus somewhat convex and labrum proximally convex at middle. End section of maxillary palpi almost equal to the length of the third; labial palpi short, end section of labial palpi equal to the total length of remainder sections.

Pronotum broad and flattened, anterior margin straight and the posterior convex; median groove of pronotal disc distinct. Longitudinal veins of tegmina parallel. Hindwings longer than tegmina, uncovered portion slightly shorter than hind femur.

Inner tympanum shaped as elongate oval; outer tympanum absent. Hind tibiae evenly distributed with spines, armed with spurs distally (numbered 5:4); outer apical spurs two (equal in length) and three inner ones (the dorsal one longest, two times longer than the longest; ventral one shortest).

Genitalia. Lateral lobes of epiphallus triangular, inner of epiphallic lateral lobes apically armed with small hook. Middle lobes of epiphallus small, acute apically. Ectoparamere proximally rod-like, not straight, medially convex; apically expanded and shaped as triangular. The ventral of epiphallus bearing a short projection.

Coloration.­ Body colored brown. Eyes yellowish brown; frontal rostrum brown; clypeus and labrum yellowish. Pronotum ornamented with median groove. Tegmina dark brown.

Female. Resembles male. Slightly darker than male. Ovipositor smooth, brown, arrow-shaped and equal to the length of posterior femur.

Remarks. This species resembles Aphonoides acuta Ingrisch, 1997 and Aphonoides morobe Gorochov, 2008 in features of body and genitalia, but it is distinguished by the epiphallic lateral lobes and ectoparamere. A. cuvto sp.­ nov. differs from A. acuta and A. morobe in the shape of the ectoparamere. Ectoparamere A. cuvto sp.­nov. apically slightly narrowed, that of the others apically widened. Besides, the epiphallic lateral lobes of A. cuvto sp.­nov. apically obtuse and what of A. acuta apically acute.
