Scaphotettix Matsumura, 2014

Scaphotettix Matsumura, 1914: 227; Zahniser & Dietrich, 2013: 118.

Type species: Scaphotettix viridis Matsumura, 1914 .

Diagnosis. Body dorsoventrally flattened. Head slightly narrower to slightly wider than pronotum; crown longer medially than length next to eye; ocelli on anterior margin of crown, close to eye; face angularly convex dorsally in profile; anteclypeus narrowing towards apex; antennae arising near upper corners of eye. Forewing with outer subapical cell extended to wing margin. Male genitalia. Pygofer lobe elongate, with one or two elongate processes at mid-ventral margin, extending caudally, rarely curved medially ( S. aurantiacus), dorsal margin rarely with a short internal process on each side ( S. aurantiacus). Subgential plate long-triangular with uniseriate row of macrosetae on lateral margin. Style elongate and linear, with margin between inner and outer basal arms strongly oblique; preapical lobe undeveloped; apical process tapered to acute or rounded apex, short and curved laterally, rarely elongate and curved medially ( S. aurantiacus). Connective with arms broadly arched, stem reduced, connective rarely trapezoidal ( S. aurantiacus). Aedeagal shaft simple, curved dorsally with or without processes; gonopore apical on ventral surface; rarely with distinct basal apodeme and preatrium present ( S. aurantiacus).

Distribution. Oriental and Pacific region.

Remarks. Scaphotettix was revised by Dai et al. (2009) who adequately described the genus; all previously described species except the type species were removed from the genus and three species were described as new. Subsequently, Zahniser & Dietrich (2013) transferred the genus from Athysanini to Mukariini .
